Consumption after Corona: Consumers focus on Quality and Sustainability

Study by Roland Berger and Potloc

  • Consumers expect more quality (67%) and sustainability (51%) from brands and products
  • Small retail stores are trendy and score with exclusive product range
  • Furniture, household and garden articles remain in focus

The Covid pandemic has changed the purchasing behavior. Consumers are focusing primarily on brands with high quality standards (67%) and sustainable products (51%). Even though the trend towards online shopping remains unbroken, small stores in particular can score points with exclusive product ranges. Almost a third (32%) of consumers visit these types of stores more frequently than before the crisis. These are the core findings of the "Decoding Consumer Behavior" study published in fall 2021 by Roland Berger and Potloc, for which 2,100 consumers from twelve countries were surveyed.

The Covid pandemic has changed the purchasing behavior. Consumers are focusing primarily on brands with high quality standards (67%) and sustainable products (51%). Even though the trend towards online shopping remains unbroken, small stores in particular can score points with exclusive product ranges. Almost a third (32%) of consumers visit these types of stores more frequently than before the crisis. These are the core findings of the "Decoding Consumer Behavior" study published in fall 2021 by Roland Berger and Potloc, for which 2,100 consumers from twelve countries were surveyed.

"Overall, consumers are much more positive about the future and, for the most part, do not want to cut back further in 2022. This is good news for retailers, who had to overcome an unprecedented cut with the pandemic," says Thorsten de Boer, Partner at Roland Berger. "However, brands and retailers should take into account that consumers have different priorities when making decisions today. They also expect a consistent online presence across platforms and devices more than ever. And when they enter a store, they are looking for an exclusive experience."

Customers focus on goods for their own homes and everyday needs
In the immediate purchasing decision, value for money (68%) and quality (56%) are the most important criteria for consumers. Here, too, sustainability is becoming increasingly important. One-third want to give even greater consideration to this criterion in the future. Sustainability has finally reached the consumer," says Richard Federowski, Partner at Roland Berger.

A look at the shopping baskets shows that the focus continues to be on products for everyday needs and the home (furniture, household and garden articles). 37% have spent more money on food this year, for example, and 29% also want to make additional investments here in 2022. "The trend towards cocooning, i.e. retreating into a private domestic life, continues to have an impact. The demand for business outfits, will tend to remain at a low level in the near future," says Federowski. "Fashion from the sports and leisure sector also continues to be in high demand, and sustainability aspects will increasingly have to be taken into account in collections. However, purchases here will be made primarily online because it is simply more convenient for most people."

City center retailers can score with customer service and product ranges
Online retailing continues to gain ground globally. Online retailing continues to gain ground globally. A third of the people surveyed said they would order more online in 2021 than in the previous year. Above all, free delivery and the ability to return items easily and free of charge are important to customers. "Consumers have learned how convenient and fast online shopping can be, and this is true across all product categories - including groceries to an increasing extent," says de Boer. Services such as (virtual) advice, click-and-collect or live shopping currently play only a minor role in online shopping, but will become essential in the future.

The situation is very different when it comes to shopping in stores. German consumers in particular are flocking to city centers to enjoy the benefits of personal advice (51%). While frequencies are not yet at pre-Corona levels, conversion rates are very good. They also want to access exclusive product ranges (37%) and celebrate their shopping. "Therein lies an opportunity for retailers and city centers," says de Boer. "However, in order to compete, even small retailers can no longer do it without a digital component. To do so, they need to take their exclusive experiences to social platforms. They also know their clientele well and often sit on valuable data - this potential of 'small data' and 'communities' needs to be tapped."

Funding Project Raw Material Classification of Recycled Fibers

For centuries, old textiles have been used to make tear fibers and processed into new textile products. This effective recycling is one of the oldest material cycles in the world. Today, it is not only clothing that is recycled, but also high-quality technical textiles. As the products of the textile industry evolve, so do the demands on textile recycling. The basis for this is a clear assessment and classification of raw materials.

For centuries, old textiles have been used to make tear fibers and processed into new textile products. This effective recycling is one of the oldest material cycles in the world. Today, it is not only clothing that is recycled, but also high-quality technical textiles. As the products of the textile industry evolve, so do the demands on textile recycling. The basis for this is a clear assessment and classification of raw materials.

In the research project of the German Institutes of Textile and Fiber Research Denkendorf (DITF) and the Sächsisches Textilforschungsinstitut e.V. (STFI - Saxony Textile Research Institute), a methodology is being developed that will make it possible to analyze the tearing as well as the subsequent processes with regard to fiber quality. The systematic analysis should make it possible to optimize the subsequent spinning processes in such a way that the recycled content of the yarn can be increased without the yarn properties differing significantly from those of a yarn consisting of 100% good fibers. These yarns can then be processed into sustainable textile products such as clothing or composite components.

The project, which is funded by the BMWi/IGF, is scheduled to run for two years and will end on December 31, 2022. The main benefits for the participating companies are to enable them to make greater use of secondary raw materials, to open up new markets through technologies or products developed in the project, to initiate synergies and long-term cooperation, and to prepare a joint market presence.    

The project includes several steps:

  • Material selection and procurement
    Cotton fibers to be processed are obtained from used textiles (T-shirts) and waste from the cotton spinning mill. Aramid fibers are processed from used protective clothing and technical textiles.
  • Optimization of the preparation / dissolution of the textiles
    To ensure that the fibers are detached from the corresponding textiles as gently as possible and with a not too high reduction, exact settings have to be found for the tearing process, which are technologically very demanding and require a lot of experience.
  • Determination of the quality criteria for the evaluation of the fiber dissolution
    In order to define the quality criteria, the fibers coming from the tearing mill are determined by means of an MDTA-4 measuring device from Textechno GmbH & Co. KG. The criteria determined are to be used to characterize the (lowest possible) fiber shortening caused by the tearing process.
  • Determination of optimized settings in the spinning process
    In order to determine the optimum settings for producing a yarn from the recycled fibers, they are spun after the rotor spinning process. By adjusting the spinning process, the aim is to produce a yarn that has good uniformity and also appropriate firmness.
  • Production and comparison of yarns from recycled raw materials
    In order that the recycled fibers - consisting of aramid and cotton - can each be used to produce an area-measured material, the material is to be processed at industrial scale. For this purpose, the fibers are processed over a complete blowroom line with following sliver production over adapted cards. After drawing and the following roving production, yarns are produced according to the rotor or ring spinning process. The finished yarns are used to produce knitted fabrics.
  • Coordination, analysis of results and preparation of reports
    The final report is prepared by the DITF and the STFI. The results will be transferred through publications, technical information to associations and trade fair presentations. Regular meetings with the participating companies are planned.

Textination spoke with Stephan Baz, Deputy Head of the Competence Center Staple Fiber, Weaving & Simulation, Head of Staple Fiber Technology and Markus Baumann, Research Associate at the Competence Center Staple Fiber, Weaving & Simulation (both DITF) as well as Bernd Gulich, Head of Department Nonwovens/Recycling and Johannes Leis, Research Associate Focus Nonwovens/Recycling (both STFI) about the current status of the funding project.

What is the current status of the project?
We are currently in the phase of carrying out trials and the iterative optimization of several project components. As expected, several loops are necessary for the mechanical preparation itself and also for the adjustment of the spinning process with the different variants. Ultimately, after all, the project aims at coordinating the processes of mechanical preparation and spinning as processing in order to achieve optimum results. At the same time, determining the quality criteria of the fibers produced is not trivial. This also requires the further development of processes and test methods that can be implemented productively in industry and that allow the quality of the fibers produced to be assessed effectively and unaffected by residual yarns, for example. What is really remarkable is the interest and willingness of the industry to drive the project work forward. The considerable quantities of materials required for our trials were purchased from ReSales Textilhandel und -recycling GmbH, Altex Textil-Recycling GmbH & Co. KG and Gebrüder Otto GmbH & Co. KG. Furthermore, with Temafa Maschinenfabrik GmbH, Nomaco GmbH & Co. KG, Schill + Seilacher GmbH, Spinnerei Neuhof GmbH & Co. KG and Maschinenfabrik Rieter AG, many members of the project-supporting committee are actively involved in the project, from consulting to the providing of technologies. The company Textechno Herbert Stein GmbH & Co. KG has provided a testing device of the type MDTA4 for the duration of the project and supports our work with regard to the evaluation of the mechanically prepared fibers. We are of course particularly pleased about this, as it has allowed us to look at and analyze several technologies in both mechanical preparation, testing and spinning. We expect to be able to make more detailed statements at the beginning of the coming year.

Which approaches do you think are particularly promising?
With regard to technologies, we must refer to the evaluation and analysis of the trials, which are currently still ongoing. We will be able to go into more detail in the first quarter of next year.

Of course, things are already emerging. With meta-aramid waste, promising approaches could be found very quickly; with post-consumer cotton, this is considerably more complex. Obviously, there is a link between the quality of the raw material and the quality of the products. In some cases, we have already been able to determine very low average fiber lengths in the procured goods; to a certain extent, these are of course directly reflected in the output of our processes. From this, and this is not a new finding, a great importance of the design of the textiles is again derived.

What are the challenges?
In addition to the expected high short fiber content, the residual yarns after the tearing process are an issue of particular focus. The proportion of these residual yarns can vary between the materials and preparation technologies, but the further dissolution of the products of the tearing process is essential.

If the processes are considered further in a utilization phase, the question of design naturally also arises for the best possible use of recycled fibers. Many problems, but also the approaches to solutions for the use of comparatively short fibers, can also be expected to apply to the (multiple) use of mechanically recycled fibers.

Can we speak of upcycling in the final product?
We see yarn-to-yarn recycling neither as upcycling nor downcycling, but as closed-loop recycling. The background is that the products are to go into the same application from which they came and have to compete with primary material. This means that certain specific requirements have to be met and at the same time there is considerable price pressure. In the case of downcycling, a significant reduction in properties is accepted, while in the case of upcycling, the higher-priced application can make up for the reprocessing effort. In the attempt to produce yarn material again from yarn material, both are only permissible to a small extent. This represents the particular challenge.

What does a recyclate prepared from used textiles mean for the spinning process?
Part of this question is to be answered in the project by the detailed classification of the processed fibers and is thus the subject of the tests currently underway. It turns out that, in addition to the rather obvious points such as significantly reduced fiber length, process disturbances due to undissolved fabrics and yarn pieces, there are also less obvious aspects to be considered, such as a significantly increased outgoing quantity for processing in the spinning process. The outgoing quantity is of particular interest here, because in the end the newly produced yarn should also contain a considerable proportion of prepared fibers.

What consequences does this have for textile machinery manufacturing?
The consequences that can already be estimated at the present time are that, particularly in the processing of cotton, the machinery in the spinning preparatory mill is specialized in the processing of (new) natural fibers with a certain amount of dirt. In contrast to new fibers, processed fibers are clean fibers with a significantly higher proportion of short fibers. Elements that are good at removing dirt also reject an increased amount of short fibers, which can lead to unintentionally high waste quantities under certain circumstances. It is therefore necessary to adapt the established machine technology to the new requirement profile of the raw material "processed fibers". Analogous adaptations are probably necessary along the entire processing chain up to the yarn. In the drafting system of the spinning machine, of course, this is due more to the high short fiber ratio than to elements that have been optimized for cleaning out dirt and foreign substances.

Cellulose Fibre Innovation of the Year 2022: Cellulose Fibre Solutions are expanding from hygiene and textiles as well as non-wovens up to alternatives for carbon fibres for light-weight applications.

Great submissions made the nomination for the Innovation Award difficult. All of them present promising sustainable solutions in the field of cellulose fibres value chain. Six of them now get the chance to demonstrate their potential to a wide audience in Cologne (Germany), and online.

For the second time, nova-Institute grants the “Cellulose Fibre Innovation of the Year” within the framework of the “International Conference on Cellulose Fibres 2022” (2-3 February 2022). The advisory board of the conference nominated six  products, ranging from cellulose made of orange- and wood pulp to a novel technology for cellulose fibre production. The presentations, election of the winner by the conference audience and the award ceremony will take place on the first day of the conference.

Cellulose fibres show an increasingly expanding wide range of applications, while at the same time markets are driven by technological developments and political framework conditions, especially bans and restrictions on plastics and increasing sustainability requirements. The conference provides rich information on opportunities for cellulose fibres through policy assessment, a session on sustainability, recycling and alternative feedstocks as well as latest development in pulp, cellulose fibres and yarns. This includes application such as non-wovens, packaging and composites.

Here are the nominees:
Carbon Fibres from Wood – German Institutes of Textile and Fiber Research Denkendorf (Germany)
The HighPerCellCarbon® technology is a sustainable and alternative process for the production of carbon fibres made from wood. The technology starts with wet spinning of cellulosic fibres using ionic liquids (IL) as direct solvent in an environmentally friendly, closed loop filament spinning process (HighPerCell® technology). These filaments are directly converted into carbon fibres by a low-pressure stabilisation process, followed by a suitable carbonisation process. No exhaust fumes or toxic by-products are formed during the whole process. Furthermore, the approach allows a complete recycling of solvent and precursor fibres, creating a unique and environmentally friendly process. Carbon fibres are used in many lightweight applications and the fibres are a sustainable alternative to fossil-based ones.

Fibers365, Truly Carbon-Negative Virgin Fibres from Straw – Fibers365 (Germany)
Fibers365 are the first carbon-negative virgin straw fibres on the market. The Fibers365 concept is based on a unique, state of the art process to provide functional, carbon negative, and competitive non-wood biomass products such as virgin fibres for paper, packaging and textile purposes as well as high value process energy, biopolymer and fertilizer side streams. The products are extracted from the stems of annual food plants such as straw by a chemical-free, regional, farm level steam explosion pulping technology, allowing an easy separation of the fibres from sugars, lignin, organic acid and minerals. In the case of annual plants, CO2 emissions are recaptured within 12 months from their production date, offering “instant”, yearly compensation of corresponding emissions.

Iroony® Hemp and Flax Cellulose – RBX Créations (France)
Iroony® is a branded cellulose made by RBX Créations from hemp. This resistant hemp plant grows quickly within in a few months, massively captures carbon and displays a high content of cellulose. The biomass is directly collected from French farmers who cultivate without chemicals or irrigation, in extended rotation cycles, contributing to soil regeneration and biodiversity. For a diversified supply, the hemp can be combined with organically-grown flax. Through its patented process, RBX Créations extracts high-purity cellulose, perfectly suitable for spinning technologies such as HighPerCell® of DITF research centre. The resulting fibres display versatile properties of fineness, tenacity and stretch, for applications like clothing or technical textiles. Iroony® combines low impact, trackability and performance.

SPINNOVA, Sustainable Textile Fibre without Harmful Chemicals – Spinnova (Finland)
Spinnova’s innovative technology enables production of sustainable textile fibres in a mechanical process, without dissolving or any harmful chemicals. The process involves use of paper-grade pulp and mechanical refining to turn pulp into microfibrillated cellulose (MFC). The fibre suspension consisting of MFC is extruded to form textile fibre, without regeneration processes. The Spinnova process does not generate any side waste, and the environmental footprint of SPINNOVA® including 65 % less CO2 emissions and 99 % less water compared to cotton production. Spinnova’s solution is also scalable: Spinnova targets to reach 1 million tonnes annual production capacity in the next 10 to 12 years.    

Sustainable Menstruation Panties: Application-driven Fibre Functionalisation – Kelheim Fibres (Germany)
Kelheim’s plant-based and biodegradable fibres contribute significantly to a sustainable future in the field of reusable hygiene textiles. Through innovative functionalisation they are specifically adjusted to the requirements of the single layers and thereby reach a performance comparable to that of synthetic fibres. A unique duality in fibre technology is created: sustainably manufactured cellulosic fibres that allow for high wearing comfort and reusability with extraordinary, durable performance. Fibre concepts comprise Celliant® Viscose, an in-fibre infrared solution and Danufil® Fibres in the top sheet, Galaxy, a trilobal fibre for the ADL, Bramante, a hollow viscose fibre, in the absorbing core and a water repellent woven fabric, a biodegradable PLA film or a sustainable coating as a back sheet.

TENCEL™ branded Lyocell Fibre made of Orange and Wood Pulp – Orange Fiber (Italy)
Orange Fiber is the world's first company to produce a sustainable textile fibre from a patented process for the extraction of cellulose to be spun from citrus juice leftovers, which are more than 1 million tonnes a year just in Italy. The result of our partnership with Lenzing Group, leading global producer of wood-based specialty fibres, is the first ever TENCEL™ branded lyocell fibre made of orange and wood pulp. A novel cellulosic fibre to further inspire sustainability across the value chain and push the boundaries of innovation. This fibre, part of the TENCEL™ Limited Edition initiative, is characterized by soft appeal and high moisture absorbance and has already obtained the OEKO-TEX Standard 100 certificate and is undergoing a diverse set of other sustainability assessments.

IT solutions for stable supply chains

Global supply chains comprise complex networks, making them particularly vulnerable. The UK is a prime example of this, where logistics problems are currently resulting in empty supermarket shelves and closed gas stations. Fraunhofer experts provide IT solutions that counteract supply bottlenecks in international goods traffic and maintain robust supply chains.

Earthquakes in South America, floods in Germany or political unrest in Asia: all compromise supply chains. A research team at the Fraunhofer Institute for Industrial Mathematics ITWM is developing mathematical methods that can be used to calculate how to minimize risks to supply chains. “Mathematically speaking,” explains Dr. Heiner Ackermann, Deputy Head of Optimization – Operations Research, “these disruptive events create a multidimensional decision problem.”

Earthquakes in South America, floods in Germany or political unrest in Asia: all compromise supply chains. A research team at the Fraunhofer Institute for Industrial Mathematics ITWM is developing mathematical methods that can be used to calculate how to minimize risks to supply chains. “Mathematically speaking,” explains Dr. Heiner Ackermann, Deputy Head of Optimization – Operations Research, “these disruptive events create a multidimensional decision problem.”    

Cushioning risks without additional costs
Ackermann’s team of experts analyze the properties of supply chains using mathematical models. The failure scenarios simulated on the basis of these calculations show at which points there is a greater need for action. In the second step, the researchers focus on holistic optimization – for a more robust supply chain that can cushion risks without incurring major costs. The experts package all variables into a multicriteria optimization problem. In this way, they determine the best possible solution for the triad of resilience, cost and risk. Algorithms calculate the optimum balance and with it various options for raw materials, suppliers and warehousing. Even the use of alternative materials is considered. The top priority: as few assumptions as possible. “Our work has set the ball rolling – companies that previously relied on Excel spreadsheets and their gut feeling are now engaging in very fruitful discussions,” explains Ackermann, adding: “Whether you are dealing with supply chains or supply networks, mathematics is a universal and very effective tool.”

Early detection of potential supply shortages
The Fraunhofer Institute for Material Flow and Logistics IML also offers highly effective support for testing and optimizing supply chains with its Order-To-Delivery-NETwork (OTD-NET) simulator. Thanks to this tool, planning and material flow processes from order to delivery can be continuously assessed. “OTD-NET maps even highly complex supply chains in full and at all levels, including the planning and information flow processes. Using various parameters, it is possible to accurately model cooperation between supply chain partners on the computer,” specifies Marco Motta, Head of Supply Chain Engineering at Fraunhofer IML.
 
Combining digital twins of supply chains with simulations
The tool set examines networks particularly with regard to customer promises in terms of delivery reliability and quality, etc., costs, environmental considerations and, in the analysis of alternative scenarios, resilience. “In the simulation, I can easily play around with demand peaks, a slump in the respective market or scenarios in which production is disrupted,” explains the Fraunhofer IML expert. In this way, forecasts can be made about how a supply chain will react in a state of emergency. Logistics assistance systems that combine a digital twin of the supply chain with simulations show dispatchers which cargo ships have loaded which parts, where these are located and when the consignment will be available at the required location. Supply for the next 20–30 weeks can thus be depicted for global networks, enabling potential bottlenecks to be detected early on. Tracking is also a distinguishing feature of the solution for demand and capacity management. Not only is the number of parts affected displayed but planners can also directly see the impact of this on the whole of production.
 
Most recently, both the automotive and medical sectors have suffered from supply bottlenecks. Saskia Sardesai, Senior Scientist at Fraunhofer IML, is leading different research projects in which OTD-NET is being used to increase resilience in value creation networks for medical supplies. “Especially smaller and medium-sized companies were addressing this problem using existing spreadsheet analysis tools. However, this approach does not identify dynamics.” This is where OTD-NET comes into play: The simulation dynamically shows over a long period whether all parts will be at the right location at the right time. “If all parts are available except for those from my transatlantic supplier and there is no alternative supplier in Europe, I will quickly have a break in my chain lasting over a month,” outlines the specialist.

Increasing the European manufacturing sector’s resilience to future pandemics In the European research project “CO-VERSATILE”, overseen by Sardesai, participants are doing everything in their power to increase the European manufacturing sector’s resilience to future pandemics. The supply chain should be able to react quickly and effectively to a sudden spike in demand for strategic medical supplies. To that end, experts at Fraunhofer IML have developed a simulation model that takes into account future peaks and fluctuations in demand as well as supplier risks. Companies are immediately given an overview of which effects they will have to face. “We have created very simple models to facilitate rapid feedback and implementation for a variety of companies,” explains the project manager. Particular attention was paid to capacities, lead times, transportation frequency and possible supply restrictions. Users can see how individual factors interplay – an invaluable advantage compared to the long-standing Excel solution.

Toray Industries: A Concept to change Lives

Founded in January 1926, Tokyo-based Japanese chemical company Toray Industries, Inc. is known as the world's largest producer of PAN (polyacrylonitrile)-based carbon fibers. But its overall portfolio includes much more. Textination spoke with Koji Sasaki, General Manager of the Textile Division of Toray Industries, Inc. about innovative product solutions, new responsibilities and the special role of chemical companies in today's world.

Toray Industries is a Japanese company that - originating in 1926 as a producer of viscose yarns - is on the home stretch to its 100th birthday. Today, the Toray Group includes 102 Japanese companies and 180 overseas. They operate in 29 countries. What is the current significance of the fibers and textiles business unit for the success of your company?

Toray Industries is a Japanese company that - originating in 1926 as a producer of viscose yarns - is on the home stretch to its 100th birthday. Today, the Toray Group includes 102 Japanese companies and 180 overseas. They operate in 29 countries. What is the current significance of the fibers and textiles business unit for the success of your company?

The fibers’ and textiles’ business is both the starting point and the foundation of Toray's business development today. We started producing viscose yarns in 1926 and conducted our own research and development in nylon fibers as early as 1940. And since new materials usually require new processing methods, Toray also began investing in its own process technology at an early stage. On the one hand, we want to increase our sales, and on the other hand, we want to expand the application possibilities for our materials. For this reason, Toray also began to expand its business from pure fibers to textiles and even clothing. This allows us to better respond to our customers' needs while staying at the forefront of innovation.

Over the decades, Toray has accumulated a great deal of knowledge in polymer chemistry and organic synthesis chemistry - and this know-how is the foundation for almost all of our other business ventures. Today, we produce a wide range of advanced materials and high-value-added products in plastics, chemicals, foils, carbon fiber composites, electronics and information materials, pharmaceuticals, medicine and water treatment. However, fibers and textiles remain our most important business area, accounting for around 40% of the company's sales.

What understanding, what heritage is still important to you today? And how do you live out a corporate philosophy in the textile sector that you formulate as "Contributing to society through the creation of new value with innovative ideas, technologies and products"?

Toray has consistently developed new materials that the world has never seen before. We do this by focusing on our four core technologies: Polymer chemistry, organic synthetic chemistry, biotechnology and nanotechnology. We do this by focusing on our four core technologies: Polymer chemistry, organic synthetic chemistry, biotechnology and nanotechnology. For textiles, this means we use new polymer structures, spinning technologies and processing methods to develop yarns with unprecedented properties. We always focus on the needs and problems of the market and our customers.

This approach enables us to integrate textiles with new functions into our everyday lives that natural fibers and materials cannot accomplish. For example, we offer sportswear and underwear that absorb water excellently and dry very quickly, or rainwear and outdoor clothing with excellent water-repellent properties that feature a less bulky inner lining. Other examples include antibacterial underwear, uniforms, or inner linings that provide a hygienic environment and reduce the growth of odor-causing bacteria. People enjoy the convenience of these innovative textiles every day, and we hope to contribute to their daily comfort and improve their lives in some way.

In 2015, the United Nations adopted 17 sustainable development goals – simply known as the 2030 Agenda, which came into force on January 01, 2016. Countries were given 15 years to achieve them by 2030. In your company, there is a TORAY VISION 2030 and a TORAY SUSTAINABILITY VISION. How do you apply these principles and goals to the textile business? What role does sustainability play for this business area?

Sustainability is one of the most important issues facing the world today - not only in the textile sector, but in all industries. We in the Toray Group are convinced that we can contribute to solving various problems in this regard with our advanced materials. At the same time, the trend towards sustainability offers interesting new business approaches. In our sustainability vision, we have set four goals that the world should achieve by 2050. And we have defined which problems need to be addressed to achieve this.

We must:

  1. accelerate measures to combat climate change,
  2. implement sustainable, recycling-oriented solutions in the use of resources and in production,
  3. provide clean water and air, and
  4. contribute to better healthcare and hygiene for people around the world.

We will drive this agenda forward by promoting and expanding the use of materials that respond to environmental issues. In the textile sector, for example, we offer warming and cooling textiles – by eliminating the need for air conditioning or heating in certain situations, they can help reduce energy costs. We also produce environmentally friendly textiles that do not contain certain harmful substances such as fluorine, as well as textiles made from biomass, which use plant-based fibers instead of conventional petrochemical materials. Our product range also includes recycled materials that reduce waste and promote effective use of resources.

The TORAY VISION 2030, on the other hand, is our medium-term strategic plan and looks at the issue of sustainability from a different angle: Toray has defined the path to sustainable and healthy corporate growth in it. In this plan, we are focusing on two major growth areas: Our Green Innovation Business, which aims to solve environmental, resource and energy problems, and the Life Innovation Business, which focuses on improving medical care, public health, personal safety and ultimately a longer expectancy of life.

Innovation by Chemistry is the claim of the Toray Group. In a world where REACH and Fridays for Future severely restrict the scope of the chemical industry, the question arises as to what position chemistry can have in the textile industry. How do chemistry, innovation and sustainability fit together here?

The chemical industry is at a turning point today. The benefits that this industry can bring to civilization are still enormous, but at the same time, disadvantages such as the waste of resources and the negative impact on the environment and ecosystems are becoming increasingly apparent. In the future, the chemical industry will have to work much more towards sustainability - there is no way around it.

As far as textiles are concerned, we believe there are several ways to make synthetic materials more sustainable in the future. One of these, as I said, is materials made from plants instead of petrochemical raw materials. Another is to reduce the amount of raw materials used in production in the first place – this can be achieved, for example, by collecting and recycling waste materials from production or sales. Biodegradable materials that reduce the impact of waste products on the environment are another option worth pursuing, as is the reduction of environmentally harmful substances used in the production process. We are already looking at all of these possibilities in Toray's synthetic textiles business. At the same time, by the way, we make sure to save energy in our own production and minimize the impact on the environment.

Toray's fibers & textiles segment focuses on synthetic fibers such as nylon, polyester and acrylic, as well as other functional fibers. In recent years, there has been a clear trend on the market towards cellulosic fibers, which are also being traded as alternatives to synthetic products. How do you see this development – on the one hand for the Toray company, and on the other hand under the aspect of sustainability, which the cellulosic competitors claim for themselves with the renewable raw material base?

Natural fibers, including cellulose fibers and wool, are environmentally friendly in that they can be easily recycled and are rapidly biodegradable after disposal. However, to truly assess their environmental impact, a number of other factors must also be considered: Primarily, there is the issue of durability: precisely because natural fibers are natural, it is difficult to respond to a rapid increase in demand, and quality is not always stable due to weather and other factors.

Climatic changes such as extreme heat, drought, wind, floods and damages from freezing can affect the quantity and quality of the production of natural fibers, so that the supply is not always secured. In order to increase production, not only does land have to be cleared, but also large amounts of water and pesticides have to be used to cultivate it – all of which is harmful to the environment.

Synthetic fibers, on the other hand, are industrial products manufactured in controlled factory environments. This makes it easier to manage fluctuations in production volume and ensure consistent quality. In addition, certain functional properties such as resilience, water absorption, quick drying and antibacterial properties can be embedded into the material, which can result in textiles lasting longer in use.

So synthetic fibers and natural fibers, including cellulose fibers, have their own advantages and disadvantages – there is no panacea here, at least not at the moment. We believe: It is important to ensure that there are options that match the consumer's awareness and lifestyle. This includes comfort in everyday life and sustainability at the same time.

To what extent has the demand for recycled products increased? Under the brand name &+™, Toray offers a fiber made from recycled PET bottles. Especially with the "raw material base: PET bottles", problems can occur with the whiteness of the fiber. What distinguishes your process from that of other companies and to what extent can you compete with new fibers in terms of quality?

During the production of the "&+" fiber, the collected PET bottles are freed from all foreign substances using special washing and filtering processes. These processes have not only allowed us to solve the problem of fiber whiteness – by using filtered, high-purity recycled polyester chips, we can also produce very fine fibers and fibers with unique cross sections. Our proven process technologies can also be used to incorporate specific textures and functions of Toray into the fiber. In addition, "&+" contains a special substance in the polyester that allows the material to be traced back to the recycled PET bottle fibers used in it.

We believe that this combination of aesthetics, sustainability and functionality makes the recycled polyester fiber "&+" more competitive than those of other companies. And indeed, we have noticed that the number of requests is steadily increasing as companies develop a greater awareness of sustainability as early as the product planning stage.

How is innovation management practiced in Toray's textile division, and which developments that Toray has worked on recently are you particularly proud of?

The textile division consists of three sub-divisions focusing on the development and sale of fashion textiles (WOMEN'S & MEN'S WEAR FABRICS DEPT.), sports and outdoor textiles (SPORTS WEAR & CLOTHING MATERIALS FABRICS DEPT.) and, specifically for Japan, textiles for uniforms used in schools, businesses and the public sector (UNIFORM & ADVANCED TEXTILES DEPT.).

In the past, each division developed its own materials for their respective markets and customers. However, in 2021, we established a collaborative space to increase synergy and share information about textiles developed in different areas with the entire department. In this way, salespeople can also offer their customers materials developed in other departments and get ideas for developing new textiles themselves.

I believe that the new structure will also help us to respond better to changes in the market. We see, for example, that the boundaries between workwear and outdoor are blurring – brands like Engelbert Strauss are a good example of this trend. Another development that we believe will accelerate after the Corona pandemic is the focus on green technologies and materials. This applies to all textile sectors, and we need to work more closely together to be at the forefront of this.

How important are bio-based polyesters in your research projects? How do you assess the future importance of such alternatives?

I believe that these materials will play a major role in the coming years. Polyester is made from purified terephthalic acid (PTA), which again consists of paraxylene (PX) and ethylene glycol (EG). In a first step, we already offer a material called ECODEAR™, which uses sugar cane molasses waste as a raw material for EG production.

About 30% of this at least partially bio polyester fiber is therefore biologically produced, and the material is used on a large scale for sportswear and uniforms. In the next step, we are working on the development of a fully bio-based polyester fiber in which the PTA component is also obtained from biomass raw materials, such as the inedible parts of sugar cane and wood waste.

Already in 2011, we succeeded in producing a prototype of such a polyester fiber made entirely from biomass. However, the expansion of production at the PX manufacturer we are working with has proven to be challenging. Currently, we are only producing small sample quantities, but we hope to start mass production in the 2020s.

Originally starting with yarn, now a leading global producer of synthetic fibers for decades, you also work to the ready-made product. The range extends from protective clothing against dust and infections to smart textiles and functional textiles that record biometric data. What are you planning in these segments?

In the field of protective clothing, our LIVMOA™ brand is our flagship material. It combines high breathability to reduce moisture inside the garment with blocking properties that keep dust and other particles out. The textile is suitable for a wide range of work environments, including those with high dust or grease levels and even cleanrooms. LIVMOA™ 5000, a high quality, also demonstrates antiviral properties and helps to ease the burden on medical personnel. The material forms an effective barrier against bacteria and viruses and is resistant to hygroscopic pressure. Due to its high breathability, it also offers high wearing comfort.

Our smart textile is called hitoe™. This highly conductive fabric embeds a conductive polymer – a polymer compound that allows electricity to pass through - into the nanofiber fabric. hitoe™ is a high-performance material for detecting biosignals, weak electrical signals that we unconsciously emit from our bodies.

In Japan, Toray has developed products for electrocardiographic measurements (ECGs) that meet the safety and effectiveness standards of medical devices. And in 2016, we submitted an application to the Japanese medical administrative authorities to register a hitoe™ device as a general medical device – this registration process is now complete. Overall, we expect the healthcare sector, particularly medical and nursing applications, to grow – not least due to increasing infectious diseases and growing health awareness among the elderly population. We will therefore continue to develop and sell new products for this market.

In 1885, Joseph Wilson Swan introduced the term "artifical silk" for the nitrate cellulose filaments he artificially produced. Later, copper, viscose and acetate filament yarns spun on the basis of cellulose were also referred to as artifical silk. Toray has developed a new innovative spinning technology called NANODESIGN™, which enables nano-level control of the fineness and shape of synthetic fibers. This is expected to create functions, aesthetics and textures that have not existed before. For which applications do you intend to use these products?

In NANODESIGN™ technology, the polymer is split into a number of microscopic streams, which are then recombined in a specific pattern to form a new fiber. By controlling the polymer flow with extreme precision, the fineness and cross-sectional shape of the fiber can be determined much more accurately than was previously possible with conventional microfiber and nanofiber spinning technologies. In addition, this technology enables the combination of three or more polymer types with different properties in one fiber – conventional technologies only manage two polymer types. This technology therefore enables Toray to specify a wide range of textures and functions in the production of synthetic fibers that were not possible with conventional synthetic fibers – and even to outperform the texture and feel of natural fibers. Kinari, our artificial silk developed with NANODESIGN technology, is a prime example here, but the technology holds many more possibilities – especially with regard to our sustainability goals.

What has the past period of the pandemic meant for Toray's textile business so far? To what extent has it been a burden, but in which areas has it also been a driver of innovation? What do you expect of the next 12 months?

The Corona catastrophe had a dramatic impact on the company's results: The Corona catastrophe had a dramatic impact on the company's results: In the financial year 2020, Toray's total sales fell by about 10% to 188.36 billion yen (about 1.44 billion euros) and operating profit by about 28% to 90.3 billion yen (about 690 million euros). The impact on the fiber and textile business was also significant, with sales decreasing by around 13% to 719.2 billion yen (approx. 5.49 billion euros) and operating profit by around 39% to 36.6 billion yen (approx. 280 million euros).

In the financial year 2021, however, the outlook for the fibers and textiles sector is significantly better: So far, the segment has exceeded its goals overall, even if there are fluctuations in the individual areas and applications. In the period from April to June, we even returned to the level of 2019. This is partly due to the recovering sports and outdoor sector. The fashion apparel market, on the other hand, remains challenging due to changing lifestyles that have brought lock-downs and home-office. We believe that a full recovery in business will not occur until the travel and leisure sector returns to pre-Corona levels.

Another side effect of the pandemic that we feel very strongly, is the growing concern about environmental issues and climate change. As a result, the demand for sustainable materials has also increased in the apparel segment. In the future, sustainability will be mandatory for the development and marketing of new textiles in all market segments. Then again, there will always be the question of how sustainable a product really is, and data and traceability will become increasingly important. In the coming years, the textile division will keep a close eye on these developments and develop materials that meet customers' needs.

Live in Munich: PERFORMANCE DAYS in Hall A6
In Hall A6 on the grounds of the New Trade Center in Munich, trade visitors can look forward to an extensive portfolio of exhibitors showcasing their latest functional textiles and fabric innovations for the upcoming winter season, winter 2023/24. Exhibitors who are unable to present their highlights on site can also be accessed via the PERFORMANCE DAYS LOOP digital platform throughout the course of the fair. As part of the newly developed “remote booths” concept, trade visitors will for the first time also find collections from exhibitors who cannot be in Munich in person for the trade show. Interactive exchanges via chat, call or video call is planned.

Two further PERFORMANCE DAYS fairs are planned as live events: The Functional Fabric Fair by PERFORMANCE DAYS in Portland, Oregon, USA on November 17-18, 2021 and Functional Textiles Shanghai by PERFORMANCE DAYS on December 6-7, 2021. Registration is open at www.functionalfabricfair.com/ and www.functionaltextilesshanghai.com/

PERFORMANCE FORUM together with USA Fair
As part of the PERFORMANCE FORUM, a select jury of experts assembles for two days prior to the fair to exchange views on the latest fabric innovations for the winter 23/24 season. In order to ensure a more global market overview, the PERFORMANCE FORUM will curate highlights for the first time in conjunction with the US fair in Portland. Consequently, the next fair in Munich will not only feature the latest products from exhibitors at the Munich fair, but also highlights from the fair in Portland. This year’s Focus Topic in cooperation with the Vaude Academy will engage with the topic “The Sustainable Future of Nylon” and a specific hand-chosen selection of fabric materials. Furthermore, as part of the winter fair, the “sustain & innovate” conference on sustainability, organized in close cooperation with SAZsport, will take an in-depth look at the topic comprising all its aspects along with speakers, webinars and discussion rounds. The program will be broadcast live from the fair and thus accessible for all who wish to follow it online in digital form.  

Eco Award and Performance Award for Innovative Winter Fabrics 23/24
This year, in addition to a PERFORMANCE AWARD, the jury also presented an ECO PERFORMANCE AWARD. An integral part of the winter edition of PERFORMANCE DAYS is the presentation of the fabric highlights and accessory trends in the respective categories for the Winter Season 2023/24 at the PERFORMANCE FORUM. The well-known segments will be joined for the first time this winter by the Shoes & Bags category, while the renowned Lifestyle Category will be continued under its new title, “Function Meets Fashion”. The high level of innovation and quality of many of the fabrics submitted this year are particularly striking.

“The fusion of the two PERFORMANCE FORUMs of our fairs in Munich and Portland has lead to a significant increase in quality and innovation. Thanks to the new partnership, not only were we able to get new, exciting manufacturers on board, but there was also a significant increase in participation in general“, says Marco Weichert, CEO of PERFORMANCE DAYS.

Natural fabrics such as organic cotton, wool or canvas remain in demand. These are joined by significantly more plant fibers such as hemp, coconut shell, bamboo or fibers derived from pineapple or banana leaves. The additional use of castor oil, zinc or ginger supports the antibacterial effect, ensures enhanced breathability, optimum temperature management and makes the fabric soft, light and kind to the skin. The topic of recycling presents itself in various new facets and features exciting trends. The portfolio ranges from the recycling of marine waste, such as old buoys, plastic waste or fishing nets, to the recycling of waste from the automotive and computer industries, such as old car tires or computer chips. Natural dyeing methods are also gaining increasing importance, as is the recycling of materials into the textile loop.

In the Marketplace, visitors have the opportunity to view over 13,000+ products from exhibitors, including the fabric highlights of the individual categories at the PERFORMANCE FORUM. In order to be able to present the fabrics to the digital visitors as realistically as possible in terms of feel, design and structure, the PERFORMANCE FORUM has been equipped with groundbreaking 3D technology, including innovative tools such as 3D images, video animations and U3M files for download.

In addition to the PERFORMANCE AWARD WINNER, which goes to drielease/Optimer, there is also an ECO PERFORMANCE AWARD WINNER, awarded to Long Advance.

Completely new look: With the innovative Dricomfort Geo, drirelease turns to a blend of 6 % Lycra, 44 % polyester and 50 % recycled polyester. The processing of the various fibers in the knitting process, in combination with the Dricomfort GEO finishing, makes the reversible interlock fabric unique.

Unique, new pattern and knit designs are possible thanks to a special jacquard knitting process used to process the recycled polyester yarn. The material impresses with its lightness and versatility. The GEO technology also ensures optimal body temperature management. The adaptable technology provides excellent thermal regulation features through efficient heat management and enhanced moisture transport to optimize comfort and performance. Moreover, GEO boasts UV protection up to 50+.

New recycling variant: Long Advance presents LNT-21191-Z4C, a post consumer nylon that opens up a new world to recycling. The fabric, which consists of 7 % elastane and 93% recycled polyamide via Mass Balance, introduces new facets to the topic of recycling. BASF is using tire waste from now on and processes them into a new fiber. fiber. Due to the recycling, the need for synthetic fabrics are reduced to replace petroleum-based plastics with plastics made from renewable raw materials.

NGST - Next Generation Protective Textiles

  • Efficient Production of Novel, High-Quality Infection-Protective Textiles

 
Considerable shortages of protective textiles, especially respirators, occurred during the SARS-CoV-2 pandemic, which were exacerbated by the lack of sufficient production capacity in Germany and the EU at the time. Short-term retooling at EU companies as well as importing goods often did not lead to success, as these protective textiles were of highly variable quality, which had a negative impact on safety.

The "Next Generation Protective Textiles" initiative aims to remedy this situation by researching new approaches for the production of high-quality protective textiles.

The "NGST" project is divided into several subtasks
The project includes:

  • Efficient Production of Novel, High-Quality Infection-Protective Textiles

 
Considerable shortages of protective textiles, especially respirators, occurred during the SARS-CoV-2 pandemic, which were exacerbated by the lack of sufficient production capacity in Germany and the EU at the time. Short-term retooling at EU companies as well as importing goods often did not lead to success, as these protective textiles were of highly variable quality, which had a negative impact on safety.

The "Next Generation Protective Textiles" initiative aims to remedy this situation by researching new approaches for the production of high-quality protective textiles.

The "NGST" project is divided into several subtasks
The project includes:

  • qualified selection of basic materials
  • studies on up-scaling to create the conditions for a rapid expansion of production capacities
  • development of novel antiviral coatings
  • comprehensive biological and material science analysis to verify the improved properties and also to open up new methods of quality control.

The protective textiles to be developed in the project have a wide range of applications beyond use in the medical field and in civil protection. In principle, wherever immediate cleaning and disinfection are difficult or special filtration tasks are necessary, such as in mobile or stationary filter systems for air purification or for individual personal protection.

In this project, the Fraunhofer IGCV is researching the development of a manufacturing process for nonwovens as a basis for infection protection and filtration media based on wet nonwoven technology. Compared to the state of the art (meltblown technology), this is potentially characterised by significantly increased production capacities as well as increased flexibility with regard to material variety. The main challenges here are the very high quality requirements based on low basis weights for processing the finest possible micro-staple fibres..
          
Pursuing novel approaches to increase quality and productivity in the production of protective textiles
The aim is to provide optimised nonwoven materials as a starting material for subsequent antiviral coatings, and to assess and demonstrate the high technological potential of wet nonwoven technology in this field of application.

For this purpose, an existing pilot wetlaid nonwoven line was specifically modified on a pilot plant scale. This makes it possible to produce nonwoven materials from micro-staple fibres in the required very high quality in terms of uniformity, basis weight, blending and thickness profile with high reproducibility. A standard PP nonwoven was used as a comparison system, which was produced according to the current state of the art using meltblown technology. In addition to the PP comparison variants, however, the processing of PLA, viscose and PET staple fibres, among others, was also investigated. The focus here is on maximum fibre fineness (microfibres) in each case in order to achieve the largest possible specific fibre surface or effective area in the nonwoven. In order to emphasise the significantly increased flexibility of wetlaid technology, particularly innovative variants based on modified bi-component fibres with maximised fibre surface area as well as split fibres are also being conceptually tested.

In addition to aspects of direct material and process development, the scale of the pilot plant provides a comprehensive data basis for estimating a later scaling up to an industrial series. This should create a technological starting point for the ramp-up of an efficient, national production of fleece-based infection control materials based on wet-laying technology.

FESPA back with first live events in Europe

FESPA has kick-started business recovery in the speciality print and signage communities with the successful return of FESPA Global Print Expo and European Sign Expo 2021 (12 – 15 October 2021) after a two-year gap.

The first live FESPA events in Europe since Spring 2019 attracted a strong audience dominated by business leaders, who came with an appetite to update their industry knowledge with a view to short- and medium-term investment.

FESPA has kick-started business recovery in the speciality print and signage communities with the successful return of FESPA Global Print Expo and European Sign Expo 2021 (12 – 15 October 2021) after a two-year gap.

The first live FESPA events in Europe since Spring 2019 attracted a strong audience dominated by business leaders, who came with an appetite to update their industry knowledge with a view to short- and medium-term investment.

International audience of senior decision-makers
Visitors came from more than 100 countries, with a strong emphasis on the Benelux region and Germany which accounted for 49% of the audience, in line with expectations given the location in Amsterdam. Other strongly represented countries were Italy, France, the United Kingdom, Spain and Poland. As anticipated, the challenges for long-haul travellers due to COVID-related restrictions resulted in fewer visitors from outside Europe than usual for a Global Print Expo event. In total, the events attracted 7,850 unique visitors, 42% of whom attended for more than one day, bringing total visits to 11,130.

Close to half of all visitors (44%) were owners or managing directors, reinforcing the significance of the event as a springboard for business recovery and forward planning. Two in three visitors influence or make final purchasing decisions in their business.

54% of visitors stated that they were visiting FESPA for the first time, indicating a thirst for market knowledge, insight and inspiration following the commercial challenges of the pandemic.

Sources of inspiration
Printeriors was once again a popular attraction for visitors. Inspired by nature and curated by FESPA’s Textile Ambassador, Debbie McKeegan, the feature highlighted digitally printed applications targeted at printers operating in or looking to expand into interior décor. In collaboration with industry suppliers including Imageco, Kornit Digital, PONGS, swissQprint and TTS, the products displayed were produced using a series of high-end technologies, print processes and materials.

The World Wrap Masters Europe 2021 competition was also a key area of interest. In addition to a series of demonstrations and workshops from wrap experts, visitors saw competitors battle it out for the title of the “World Wrap Master of Europe 2021”. On day four, Norman Brübach from Germany was crowned the winner and will go on to compete against regional champions in the World Wrap Masters Final 2022 at FESPA Global Print Expo 2022 in Berlin.

For members of the community unable to attend the event in person, FESPA and its exhibitors provided an array of live-streamed and virtual content. The FESPA Live sessions involved conversations with key exhibitors, printers and print experts on the latest trends and innovations and these attracted 5,125 views throughout the four-day event. The recordings of the sessions are also still available to watch on demand.

Neil Felton, FESPA CEO comments: “Feedback from exhibitors was effusive, with many commenting on the upbeat mood among visitors, the unmatched value of face-to-face conversations with senior decision-makers, the enthusiasm for the new technologies and consumables on display, and the overriding sense of optimism for the future. The buzz in the halls was energising and the impression was that delegates felt very confident and happy to be in a live event environment again after such a long time.”

Neil Felton concludes: “The past two years have undoubtedly been challenging for everyone in our community. To move forward, printers and signmakers need to unearth new opportunities, explore the latest technologies and meet with peers to share ideas. This year’s events were an important milestone in our collective recovery and we hope that our next Global Print Expo and European Sign Expo, which will return to Messe Berlin, Germany, from 31 May – 3 June 2022, will finally put our whole global community back in motion.”

More than 1,200 exhibitors from 56 nations will present themselves to trade visitors in 10 halls at the Düsseldorf exhibition centre.

"The anticipation for the fair was great. This year we were particularly looking forward to the personal exchange with the industry. The positive exhibitor feedback confirms that the players in occupational health and safety want a live platform. And with the A+A we deliver what only a trade fair can offer. Tactile product presentations and innovations as well as planned and accidental encounters with the entire industry," says Birgit Horn, Project Director A+A.

Exciting topics and best practices at the A+A Congress
Parallel to the A+A trade fair, the 37th International Congress for Occupational Safety and Health deals with numerous current topics and challenges of the scene. It is organised by the Federal Working Group for Safety and Health at Work (Bundesarbeitsgemeinschaft für Sicherheit und Gesundheit bei der Arbeit, Basi). In more than 25 series of events, well-founded specialist knowledge and current political topics are conveyed and intensively discussed for all stakeholders in matters of safety and health at work, on site and in some cases also digitally. "Even the opening event will be interesting. Social partners and other stakeholders will discuss the impact of the pandemic on occupational safety and health and the return to the 'new normal' that is now beginning," says Basi Managing Director Dr Christian Felten.

At the A+A Congress, renowned experts from the field of occupational safety and health will provide answers to central questions such as: How does the digitalisation of work affect the health and safety of employees? How do I, as an occupational safety specialist, advise companies and employees on this? How should decentralised workplaces be managed in a safe and healthy way? How do you determine a healthy balance between mobile and stationary work? What is the need for occupational prevention in the case of musculoskeletal stress and what is the current need for prevention in the case of activities involving carcinogenic hazardous substances and bio-substances? There are many interesting events on this and many other topics, further information can be found at www.basi.de/kongress. .

Trend topics at the A+A 2021
Digital performance and sustainability determine the current discussion and will continue to strongly influence the future of work. In addition to these two megatrends at A+A 2021, the focus of the framework programme is on solutions for the future (Future Solutions), new working worlds (New Work) and the topic of hygiene and pandemics.

A+A Live: Experience safe and healthy work with all senses
Best practices using state-of-the-art products and processes will be communicated under the label "A+A live" in the Trend Forum, the Theme Park Operational Fire Protection and Emergency Management, the Robotics Park and the Start UP Zone.

In Hall 10, trade visitors will find the Safety and Health Meeting Point, the competence centre for all occupational health and safety issues. This is where Basi's member and partner organisations present themselves..

The Robotics Park is also located in Hall 10, it is divided into the Self Experience Space and the Exoworkathlon. The partner of the Robotics Park is the Fraunhofer IPA from Stuttgart.

Micromechanical Simulation of the Resilience of Nonwovens

Nonwovens are an important component of different products of several uses, e.g. transport of humidity in sanitary products, insulation materials or filters. Nonwovens are usually produced on large engineering facilities. For this, experimental studies of design with regard to the optimization of these nonwoven-structures prove to be very difficult.

Influence Design Parameters
There are so many parameters of design, as for example fibers, surface weight or type of nonwoven bonding and finishing that are affecting the properties of nonwovens. For the change of one single parameter, e.g. the material of fiber, it is necessary to adapt the whole process of fabrication from the spinning of the fibers via their stacking to the nonwoven hardening.

There are so many parameters of design, as for example fibers, surface weight or type of nonwoven bonding and finishing that are affecting the properties of nonwovens. For the change of one single parameter, e.g. the material of fiber, it is necessary to adapt the whole process of fabrication from the spinning of the fibers via their stacking to the nonwoven hardening.

Following the production of such a prototype a time consuming and cost-intensive characterization of the properties of nonwovens carried out experimentally has to be done.  Therefore, for this reason detailed studies considering several parameters of design are uneconomic.

Thus, micromechanical models of simulation are developed at Fraunhofer ITWM in cooperation with Procter & Gamble Service GmbH (P & G). By means of these models it is possible to forecast numerically the effective properties of nonwovens for diverse parameters of design. To virtually modify and optimize individual parameters in this connection it is only necessary to adapt the corresponding inputs of the model.

Fast Predictions Possible
In this case, the focus of the numerical predictions is primarily lying on the time-dependent behavior of the nonwovens.  The dynamic properties can be determined by means of numerical simulation of cyclic measurements. In doing so, a good correspondence of simulation and measurements is obtained.

Compared to experiments the required time of simulation for the behavior in case of low frequencies does not change. Therefore, we can obtain rapid forecasts for the long-term behavior (month till years) and the corresponding resilience of nonwovens using numerical models. A lot of alternatives can be simulated and studied within a few hours.

The fact that not only effective (macroscopic) properties of nonwovens can be computed, but also local physical values such as distribution of tension in binding agents and fibres is a further advantage of this micromechanical  approach. So, the simulation contributes to a better understanding of the properties of nonwovens.

Future designs deal with an extension of the models with regard to simulation of the productionv processes. By this, a fully digitalized layout design of nonwovens, from the manufacturing process till the optimization of functionality is possible.

Making companies crisis-proof: Resilience as an extended security concept

Companies today face a variety of increasingly complex risks. Not least the pandemic has shown how crises can pose an existential threat to companies. The FReE tool of the Fraunhofer Institute for High-Speed Dynamics, Ernst-Mach-Institut, EMI, allows companies to measure their resilience and subsequently be prepared for upcoming crisis scenarios.
 

Companies today face a variety of increasingly complex risks. Not least the pandemic has shown how crises can pose an existential threat to companies. The FReE tool of the Fraunhofer Institute for High-Speed Dynamics, Ernst-Mach-Institut, EMI, allows companies to measure their resilience and subsequently be prepared for upcoming crisis scenarios.
 
Our world is highly complex and prone to disruption: Natural disasters, cyberattacks, power outages, terrorist attacks, pandemics and other crisis scenarios can threaten companies existentially. The corona pandemic has shown us how vulnerable the German economy really is: According to the Federal Statistical Office, in 2020 the economy fell into a deep recession after ten years of growth; especially in the second quarter of 2020, economic output saw a historic slump. There will be other crises after this pandemic. The classic methods of risk analysis and risk management, which only take into account expected risks, do not adequately protect companies against major losses.

“Companies often only consider the most likely scenarios rather than focusing on possible crisis events,“ says Daniel Hiller, Head of business unit Security and Resilience at Fraunhofer EMI in Freiburg. Teams at Fraunhofer are establishing resilience as a new security concept to help prepare organizations and companies for crises. The results of their research work include the online tool Fraunhofer Resilience Evaluator FReE and the KMU-Lagebild software, both designed to enable companies to measure and evaluate their resilience and to carry out a resilience analysis before, during and after a disruptive event.
 
The five-stage concept “Prepare, Prevent, Protect, Respond and Recover”
The online tool FReE allows companies to plan resilience strategically, to implement the abstract concept in their company and to put it into practice on management level. FReE is based on the five-stage concept “Prepare, Prevent, Protect, Respond and Recover.”  

The software comes with a list of 68 questions related to the five resilience stages. The answers provide the company with some initial information needed to assess resilience. The five stages are ordered chronologically, starting with a what-if scenario. During this Prepare stage companies prepare for disruptive situations, which helps avert damage using preventive measures during the Prevent stage.

“An aluminum processing plant, for example, might want to protect its premises with security fences and cameras, because thieves usually break in at night to steal aluminum,“ says Hiller, illustrating the first two stages using a classic example. The Protect stage, as the name suggests, aims to protect; this might include safeguarding important infrastructures or buildings with additional concrete layers or walls. If it was not possible to stave off the disaster, the Respond stage comes into play. It is now important to quickly identify the cause and extent of the damage and to preserve critical supply functions. After the incident, companies should systematically draw lessons from the crisis in order to be better able to avert future risks and to boost their resilience in a cyclical iterative process – researchers call this stage Learn and Adapt.
 
The FReE tool takes the user through the list of questions, which are ordered chronologically into the sections before, during and after a disruption and cover all company divisions. These including personnel, finance, infrastructure and technology. The tool allows you to filter by division during the evaluation process. “For example, a controller can set the filter such that only results related to finance are shown,” says Hiller. Possible questions include: “Is there a disaster manager in the event of a disruption?“, “What are their qualifications and powers?” or “What are the financial reserves for emergencies?” The evaluation is shown in the radar chart, with the worst result being at zero percent in the graticule.

FReE is available in three versions: The free web-based quick version includes 15 questions. The full version, which includes the complete list of 68 questions, is available on a project basis. The accompanying consulting project is based on the paid version. As part of the consulting project, Hiller and his team work together with the companies to develop appropriate measures to boost resilience and eliminate weak spots. Furthermore, additional questions can be added to the FReE tool to adapt it to the needs of specific industries. Many SMEs are already using the quick version and are planning to update it to the full version.

KMU-Lagebild project
While FReE enables companies to assess their resilience on their own, the KMU-Lagebild project supports them in carrying out a comprehensive resilience assessment. The researchers model all procedures and processes on the computer using the available data. By inputting hypothetical disruption scenarios, you can see how the system reacts to them and which countermeasures have to be taken. “By asking yourself not only what the most likely disruptions are, but also what potential incidents there are, you broaden your view of the risks. What’s more, resilient companies exhibit a high level of adaptability and flexibility,” says Hiller in summary.

Checkpoint Systems: Retail Technology Solutions – Success needs a Team

Checkpoint Systems, a division of CCL Industries, is a global leader in retail solutions. The portfolio ranges from electronic article surveillance as well as theft and loss prevention to RFID hardware and software and labeling solutions. The aim is to provide retailers with accurate, real-time inventory, speed up the replenishment cycle, prevent out-of-stocks and reduce theft to improve product availability and the customer shopping experience.

Checkpoint Systems, a division of CCL Industries, is a global leader in retail solutions.

The aim is to provide retailers with accurate, real-time inventory, speed up the replenishment cycle, prevent out-of-stocks and reduce theft to improve product availability and the customer shopping experience.

Textination spoke with Miguel Garcia Manso, Business Unit Director Germany at Checkpoint Systems, where the 44-year-old industrial engineering graduate has been working since 2018. With many years of international retail experience, he knows the needs of the retail industry very well. Before that, Miguel Garcia Manso lived in Madrid for almost 15 years, where he worked for the Spanish food retailer DIA. There he also accompanied the introduction and roll-out of article surveillance projects.

 

If you had to present Checkpoint Systems and its portfolio to someone who is not a retail professional – what would you say?

We are the retail partner and our job is to help retailers make shopping as pleasant as possible for their customers. Put simply, our solutions ensure that the right product is in the right place at the right time when the end consumer wants to buy it, instead of standing in front of an empty shelf in the worst-case scenario. Our portfolio ranges from individual anti-theft products to solutions that cover the entire supply chain and provide the greatest possible transparency of inventory.

 

It's been a long journey from the 1960s, when a small team in the U.S. developed a method to prevent the theft of books from public libraries, to becoming the international leader in 21st century article surveillance, operating in 35 countries. What legacy is still important to you today, and how would you describe the spirit at Checkpoint Systems?
 
Both questions have the same answer: On the one hand, innovative strength and, on the other, consistent exchange with the retail industry. Both have been in the focus at Checkpoint Systems from the very beginning. We develop our products and systems in close exchange with the industry, actively seek dialogue, listen to what is needed in everyday life, etc. This is very important to us and is also regularly used as a selling point for Checkpoint Systems. We definitely want to continue this.

 

You offer hardware and software technologies for retail, which is a very complex market. How do the requirements of retailers from the fashion, outdoor and textile industries differ from those of other industries?

The reasons why retail companies contact us are similar across all industries. They all want to delight their customers, retain them in the long term, and generate more sales. The ways to achieve this may differ: From omni-channel strategies for the fashion sector, to article surveillance solutions for high-priced electrical or cosmetic products, and to RFID-based fresh food solutions for food retailers to reduce food waste.
The requirements of the industries differ, especially when it comes to labels. Depending on the size and price of the product as well as the desired technology, we recommend different labels – or develop them in close coordination with the customer. For the Polish fashion company LPP, for example, we have just developed a special dual RF and RFID tag that blends harmoniously into the store design.

 

Magic word RFID – the contactless and automated reading and storing of data based on electromagnetic waves is the centerpiece of your technologies. You even encourage your customers to develop their own RFID strategy. What do you mean by this and are you sure that all retail companies will be able to do this on their own?

We develop the strategy together with our customers, usually as part of a pilot project. Until a few years ago, the introduction of RFID technology was actually more complex and usually involved a project lasting several years. Today, however, we can quickly calculate for each retailer in the context of a small pilot project, how much more profitable they can be with RFID and what their return on investment is. We usually start with a store scan, followed by pilot testing in selected stores, including individual training and on-site support. And by the time it is implemented in all stores, the customers themselves are RFID experts and have an understanding of what they can do with the real-time data. 

 

What does the keyword "customized" mean for Checkpoint Systems? To what extent can you map the individual needs of each customer? Or can you make every retail company – whether chain or boutique – "happy"?

We give high priority to personalized solutions. This concerns, on the one hand, the product itself and, on the other, the size of the company. As you already indicate, large retail chains obviously have different needs than small boutiques. For O₂, Telefónica Germany’s core brand, for example, we have just specially adapted our AutoPeg tags for theft protection. Instead of the standard yellow, the tags for O₂ are white with blue lettering to match the store design.
This also shows the development in the area of article surveillance in general: When article surveillance was still in its infancy, antennas and labels were mainly functional. Nowadays, they blend harmoniously into the overall look of the store design. Retailers no longer have to choose between design and functionality.

 

How is innovation management practiced in your company and which developments that Checkpoint has worked on recently are you particularly proud of?

In recent months, we have worked intensively – together with the German Employers' Liability Insurance Association (Berufsgenossenschaft Handel und Warenlogistik) – on the testing and certification of our article surveillance systems and now we can proudly say: We are the first manufacturer in Germany whose EAS systems have been tested by the CSA Group, an internationally recognized and accredited provider of testing and certification services. The CSA Group has confirmed that our radio frequency-based EAS systems comply with all standards and guidelines applicable in Germany with regard to exposure to electromagnetic fields. No safety distances need to be maintained.
The background is as follows: Retailers in Germany are obliged to prepare a risk assessment if they use an EAS system. The CE declaration of conformity, which they receive from the manufacturer when purchasing an EAS system, is not sufficient for this purpose. By testing our systems, we have created the best conditions for our customers to make such an assessment. We have also provided the relevant documents to the Employer's Liability Insurance Association.

We are also proud of the fact that we have managed to increase the clearance widths of our NEO antennas for article surveillance from two meters to 2.70 meters. This gives retailers significantly more freedom in store design. In general, store design is also a good keyword at this point: With our free-standing antennas, the design of the NS40 or even the possibility of incorporating antennas into checkout systems, we have contributed a great deal to making article surveillance aesthetically pleasing and harmoniously integrated into the whole.

 

The Covid-19 period was a disaster, especially for the stationary retail. In recent months, companies have increasingly moved in the direction of e-commerce – whether via individual store solutions or marketplaces – in order to compensate for at least part of the decline in sales. What is your advice to retailers: Can only omni-channel businesses be successful today and in the future?

Yes, that is definitely our advice to retailers. Omni-channel solutions are not going to disappear, but will continue to become more common and will be indispensable in the near future. Retailers are well advised to adapt to this new situation – also regardless of Corona – and to invest in the expansion of functioning omni-channel solutions. Customers expect the product they want, to be available when they enter a store. And if not, that they can easily have it delivered to the same store or shipped to their home. This only works with very high inventory transparency, for example through our RFID solutions.

 

Keyword: economic efficiency. Creating the much-vaunted personalized perfect shopping experience for the customer costs money, doesn't it? Stock availability, reducing inventories through clearance sales, shelf management, logistics and returns processing – to what extent can you support retailers in increasing their profitability?

NOT creating the perfect shopping experience costs a lot more – dissatisfied customers who haven't found what they want won't come back. To keep up with customer demand, many retailers therefore stock far too much products. In our experience, this amounts to an average of 42,000 items. That costs. These retailers pay high costs for warehouse space, need a lot of time for inventory processes, and end up having to reduce products significantly in order to reduce inventories.
The key to greater profitability lies in inventory accuracy. With the help of RFID technology, we can increase this to up to 99 percent. This allows us to avoid under- or overstocking, reduce the amount of storage space required, and optimize processes, including inventory. RFID can read hundreds of tags simultaneously and is more accurate and faster than manual counting. Experience shows that retailers can increase their sales by an average of three percent with our RFID technology.

 

Even if the situation in retail has eased to some extent as a result of the vaccinations, the shopping situation in on-site stores – viewed optimistically – also requires special precautions, at least for the next few months. With "safer shopping," you offer a package of various components for this purpose. What does it cover?
 
SmartOccupancy is our simple solution for controlling the number of people in salesrooms in real time. The system counts the number of people entering and leaving using Visiplus 3D, an overhead people counting sensor. When the maximum capacity is almost reached, SmartOccupancy sends an alert to the staff. This allows the staff to respond to current occupancy counts in real time, contributing to a safer environment for employees and customers. Those responsible can use SmartOccupancy to implement official instructions on the maximum number of people safely and reliably; manual counting is no longer necessary. A visual capacity indicator clearly shows customers at the door whether they are allowed to enter the store or not.
The second solution is primarily of interest to the textile and clothing industry as well as the footwear market: Inventory Quarantine is a software solution for secure, automated returns (SaaS-based). It allows retailers to park returned goods in an automated quarantine queue for a few hours. After the pre-defined time has passed, Inventory Quarantine notifies employees via push message that the piece of clothing or shoe can be cleared back to the floor or re-tagged as available in the online store. This means that items are only released when they are deemed safe for resale – while ensuring that items are put back on sale promptly. The solution helps retailers keep track of returned goods and minimize the time when products are not available on sale.

 

"Ethical consumption has finally become an attitude and has arrived in the middle of society," trend researcher Peter Wippermann commented on the results of the Otto Group's latest trend study "Living More Consciously". What does sustainability mean to Checkpoint Systems as a company, how do you reflect this finding in your product portfolio and how do you support your customers in achieving sustainability goals?

Sustainability is definitely an important topic for us at Checkpoint Systems. We regularly review our products and processes to see how we can work even more resource-efficiently, reduce production waste and lower our CO2 emissions. This also includes, how we can further reduce the power consumption of our antennas. We only develop and sell RF antennas. This technology is not only safer in terms of exposure to electromagnetic fields, but also more environmentally friendly: RF antennas require 40 to 70 percent less energy than other technologies.

Virtual Quality Inspection Optimizes Production of Filter Nonwovens

Nonwoven production received more attention than ever before from the general public in Corona times, because the technical textile is crucial for infection protection. The ultra-fine nonwoven products are manufactured in so-called meltblown processes. A cross-departmental team at the Fraunhofer Institute for Industrial Mathematics ITWM in Kaiserslautern is optimizing the entire production chain in the »ProQuIV« project. Simulations help to guarantee the product quality of the filter material despite fluctuations in production.

Nonwoven production received more attention than ever before from the general public in Corona times, because the technical textile is crucial for infection protection. The ultra-fine nonwoven products are manufactured in so-called meltblown processes. A cross-departmental team at the Fraunhofer Institute for Industrial Mathematics ITWM in Kaiserslautern is optimizing the entire production chain in the »ProQuIV« project. Simulations help to guarantee the product quality of the filter material despite fluctuations in production.

The abbreviation »ProQuIV« stands for »Production and Quality Optimization of Nonwoven Infection Protection Clothing«. This is because bottlenecks in the production of these materials were particularly evident at the beginning of the Covid 19 crisis. For the meltblown nonwovens, this optimization of the product quality is also particularly difficult because the textiles react very sensitively to fluctuations in the manufacturing processes and material impurities.

Digital Twin Keeps an Eye on the Big Picture
»Meltblown« is the name of the industrial manufacturing process whose ultra-fine fiber nonwovens are responsible for providing the crucial filtering function in face masks. In this process, the molten polymer is forced through nozzles into a forward-flowing, high-speed stream. It is stretched and cooled in a highly turbulent air flow.

»The overall process of filter media production – from the polymer melt to the filter medium – presents a major challenge in simulation,« explains Dr. Konrad Steiner, head of the »Flow and Materials Simulation« department. »In the project, we kept the big picture in mind and developed a completely integrated evaluation chain as a digital twin. In doing so, we take several key components into account at once: We simulate the typical production processes of nonwovens, the formation of the fiber structures and then the material properties – here, in particular, the filter efficiency. This allows us to quantitatively evaluate the influences of the manufacturing process on the product properties.« In each of these individual areas, Fraunhofer ITWM and its experts are among the leading research groups internationally.

Homogeneity of the Material – Fewer Clouds in the Simulation Sky
In the meltblown process, a key factor is the behavior of the filaments in the turbulent, hot and fast air flow. The properties of the filaments are strongly influenced by this air flow. The quality of the filaments – and thus the quality of the nonwovens – is influenced by many factors. Dr. Dietmar Hietel, head of the »Transport Processes« department, knows what this means more precisely in practice. His team has been working at Fraunhofer ITWM for years on the simulation of various processes involving filaments, threads, and fibers. »The focus of the project is the so-called cloudiness, i.e. the non-uniformity of the fiber distributions in the nonwoven,« explains Hietel. »We are investigating the question: How homogeneous is the fabric? Because the quality of the products can be greatly improved if we increase the uniformity. Our simulations help figure out how to do that.«

Objective Evaluation of the Homogeneity of Nonwovens
The researchers also use appropriate image analysis techniques to quantify this cloudiness. The power spectrum plays a special role here. »The cloudiness index (CLI) describes homogeneity complementary to local basis weight and its variance,« describes Dr. Katja Schladitz. She brings her expertise in image processing to the project. »Our CLI ensures a robust assessment of the homogeneity and can thus be used for different material classes and imaging techniques to be used as an objective measure.« The frequencies that go into the CLI calculation can be chosen so that the CLI is meaningful for the particular application area.

Filtration: How Efficient Are the Filters?
For the upscaling to industrial processes such as mask production, the ITWM expertise in filters is also included in the project. The »Filtration and Separation« team led by Dr. Ralf Kirsch has been working for years on the mathematical modeling and simulation of various separation processes.

»What's special about this project is that we calculated the efficiency of the filters for fluctuations of varying degrees in the fiber volume fraction,« emphasizes Kirsch. »This allows us to specify up to what level of cloudiness the required filter efficiency can be achieved at all.« As a current example of this, the figure depicts in the graphic the efficiency of a filter material for N95 masks as a function of the inhomogeneity of the nonwoven.

ITMW Methods Support Across the Entire Process Chain
In »ProQuIV«, digital twins and calculations from Fraunhofer ITWM support a holistic view and better understanding of the processes. The production of technical textiles thus not only becomes more efficient, but the nonwovens can be developed virtually without having to realize this in advance in a test facility. In this way, production capacities can be increased while maintaining or even increase the quality. Together with long-term partners from industry, the research can be put into practice quickly and efficiently.

Simulations save textile companies experiments, allow new insights, enable systematic parameter variations and solve upscaling problems that can otherwise lead to bad investments during the transition from laboratory plant to industrial plant. However, virtual implementation of nonwoven production also opens up new opportunities for optimization at other levels. For example, acoustic insulating nonwovens or even hygiene nonwovens can also be optimized in terms of their product quality precisely with regard to the material properties to be achieved – while taking into account the process fluctuations that occur.

The project is part of the Fraunhofer-Gesellschaft's »Fraunhofer versus Corona« program and was completed in April 2021. The results will flow into several follow-up projects with the nonwovens industry.

Art meets Science: Prototyping Lab for textile electronics

Anyone who thinks of research laboratories only in terms of protective suits and clean rooms is not quite right: Since April, patterns, seams and mannequins have not been uncommon in the new Textile Prototyping Lab (TPL) at Fraunhofer IZM in Berlin. With the TPL, there is now a place where creative high-tech textiles are produced and which already distinguishes itself from the style of usual research laboratories by its design. As a collaborative project with the Weißensee Kunsthochschule Berlin, textile-integrated electronics are created here for a wide range of applications from architecture to medicine.

Anyone who thinks of research laboratories only in terms of protective suits and clean rooms is not quite right: Since April, patterns, seams and mannequins have not been uncommon in the new Textile Prototyping Lab (TPL) at Fraunhofer IZM in Berlin. With the TPL, there is now a place where creative high-tech textiles are produced and which already distinguishes itself from the style of usual research laboratories by its design. As a collaborative project with the Weißensee Kunsthochschule Berlin, textile-integrated electronics are created here for a wide range of applications from architecture to medicine.

Since its opening, the lab has been available to designers and product developers to prototype individual visions in the field of e-textiles. The possibilities are virtually unlimited: From interfaces between textiles and electronics to the testing of process chains, parts of the laboratory or even the entire laboratory can be used freely. In addition to the pure development and construction work, the premises can be converted in a few moves and repurposed for workshops or exhibitions.

Malte von Krshiwoblozki, who is providing scientific support for the project at Fraunhofer IZM, cited other advantages: “Not only the modular workstations and the meeting area are attractive for joint project work, especially the machinery offers a wide range for interested parties. The ‘sewing and embroidery’ work area, for example, is equipped with several sewing machines as well as a computer-controlled embroidery machine. It thus becomes central to the TPL, as textile finishing with small-format machines is the focus of this lab's work.” Another work area covers “Cutting & Separating” with a laser cutter and a cutting plotter. In addition, there are several presses and laminators, a soldering station and a 3D printer.

In the TPL, beginners can also try their hand at e-textiles and expand their knowledge: The prototyping kit developed at Fraunhofer IZM, which includes a series of electronic modules, LEDs and sensors that can be embroidered by hand as well as by machine, is particularly helpful in this regard.

“For particularly durable electronic textiles, the textile bonder developed and built by Fraunhofer IZM researchers can also be used in cooperative projects of the Textile Prototyping Lab. The versatile modules of the prototyping kit are deliberately designed so that integration into the textile can take place not only with classic textile technology such as embroidery during the prototyping phase, but also for subsequent, more industrial implementations using the textile bonder. In keeping with the motto ‘sharing is caring’ and the principle of interdisciplinarity, we at Fraunhofer IZM are available to provide advice and support during the realization of the textile projects, so that the artists' ideas can be enriched using such new technology,” said Malte von Krshiwoblozki.

Even before the opening of the laboratory, the collaboration between the Weißensee Kunsthochschule Berlin and Fraunhofer IZM had already produced developments that combine art and research in revolutionary ways. For example, a light rail for lamps that is made of a soft and conductive textile belt was created in cooperation with the designer Stefan Diez. For the Hans Riegel Foundation's Touch Tomorrow educational project, an interactive jacket was developed that can control the color of integrated LEDs via arm movements. The team of the Textile Prototyping Lab is looking forward to upcoming, exciting and agile projects and is open for ideas from start-ups, SMEs as well as industry partners.

Next Horizons: Heimtextil presents Trends 2022/23

With “Next Horizons”, Heimtextil is presenting its design forecast for the new season 2022/23 – analysed by international trend researchers and packed with valuable inspiration and inspiring content. The new trend themes take sustainability and resource conservation in the heart of their approach. The international trade fair for home and contract textiles takes place from 11 to 14 January 2022 in Frankfurt am Main.

With “Next Horizons”, Heimtextil is presenting its design forecast for the new season 2022/23 – analysed by international trend researchers and packed with valuable inspiration and inspiring content. The new trend themes take sustainability and resource conservation in the heart of their approach. The international trade fair for home and contract textiles takes place from 11 to 14 January 2022 in Frankfurt am Main.

Three international design agencies form the Heimtextil Trend Council. Together, they develop a well-founded global vision of the coming interior trends. Alongside the Heimtextil Trend Council, Heimtextil management has established a trend forecast for the coming season and presented it live via an online conference on 1 September 2021 from Frankfurt am Main. Trend Council members Anja Bisgaard Gaede from SPOTT trends & business, Anne Marie Commandeur from Stiljinstituut Amsterdam and Kate Franklin and Caroline Till from London studio FranklinTill shared their insights into the future of the industry. Designers, interior architects and decorators get inspired by the design forecast for the new season.

Next Horizons: long-term and circular mindset
The Next Horizons are not a fixed goal or a finish line – they are mindsets. These are made up of long-term thinking, accepting that the best way to impact the world is simply not to. Paradoxically, we have begun our transition to sustainability by addressing the problems within our manufactured system instead of transforming our approach to not create waste or imbalance. Transforming our nexus begins with accepting our economies are embedded within nature. The composition of design should be accessed, made and recirculated in tune with a long-term and circular mindset and simply not create waste. The Heimtextil Trends 22/23 “Deep Nature”, “Hyper Nature”, “Beyond Identity” and “Empowered Identity” explore these new mindsets for “Next Horizons”.

Heimtextil Trends in a new digital format
With “Next Horizons”, Heimtextil is breaking new ground and, for the first time, making trend information fully available in a digital format. The brand-new online platform of Heimtextil introduces the trends richly illustrated via colours, short films, bespoke imagery, key designer features and a soundtrack. The new online platform and all trend activities are directed by SPOTT trends & business from Denmark.

The Future Materials Library is now digital
Curated by Futures Agency FranklinTill, The Future Materials Library was launched in 2020 and is now available online at www.heimtextil-trends.com/future. This collection of exciting interior material innovations from around the world celebrates radical designers, innovative manufacturers and environmentally conscious producers who are helping to turn the current, linear system of production and consumption into a circular model.

Heimtextil Trends 22/23 – overview
Deep Nature – Rebalance by relearning

“Deep Nature” explores our ecosystem’s strategies: it’s our legacy and future all at once. We need to relearn and give into untamed texture, slow process, natural structures and living colours. “Deep Nature” is a long-term transformation and relearning process which gives us the ability to rebalance the natural world for a regenerative future. The colour scale for “Deep Nature” has a harmonious and soft expression used for untamed patternmaking. Mouldy, herbal tones and delicate tones of blue and rouge create a calm, tonal, and earthy approach.

Hyper Nature – Reconnect with nature via technology
“Hyper Nature” is about reconnecting to nature through technology. The theme is a digital facilitator of nature’s blueprint, fusing technology and nature for a protopia state and creating a better tomorrow step by step. Responsive materials, technical fibres, fluid patterns and microscopic structure describes materials and textiles for “Hyper Nature”. Bioscience brings inspiration to colours of both bright and lucid and blurred nuances of green and grey. Reflections and artificial light create new perceptions of nature-based colours. Coral, salmon and light raspberry are highlights.

Beyond Identity – Values more than physical attributes
“Beyond Identity” addresses the future with hopeful messages and soft and powerful defiance toward existing norms, leaving identity in flux. For the world of home interiors and textiles “Beyond Identity” works with recycled synthetic fabric, vintage silk and satin, natural-coloured textiles and new cellulose-based textiles. They are formed via the uncontrolled colouration process of a pastel-coloured look resembling the constant flux of identity. The colours scale for “Beyond Identity” features a range of pastels, complemented with a familiar grey and pale khaki as muted transferral colours.

Empowered Identity – Empower artisanship to sustain culture
“Empower Identity” is about creating sustainable cultural connections, renewing artisan sources of inspiration in a collaborative way. Empowering Identity encourages forming new connections between heritage cultures and future generations. Recycled and heritage textiles combined with textile craft techniques as tufting, embroidered appliqué and Cross-stitch are in focus in “Empower Identity”. Primary colours resemble their colour pigment origins to support the heritage expression of the theme. Sparks of coral and a greyed lilac accompany these primary tones. Multi-coloured usage is key.

We are in a truly historic and exciting time for the textile services industry. We are all well-aware that our industry is the key to providing sustainable solutions and ecofriendly best practice. We had a series of webinars at ETSA dedicated to sustainability and circular economy being key elements of the Green Deal and our larger companies such as industrial laundries, key textile manufacturers and innovative machinery companies, are all up to the task and providing effective solutions. Our national associations too, members of ETSA, are all working synergistically to exchange their best ways forward, in Europe and beyond as we have also partners from the US. These efforts within ETSA’s value chain make us really proud and eager to go the extra mile, guiding our members also towards those areas which seem to be the most challenging. For instance, the new EU Climate Law, which calls for 55% CO2 reductions by 2030: this means that European industries will all have to do better to make us reach these targets in less than nine years. We know ETSA could represent the right network to identify the best way forward on this issue and truly perform and deliver what the EU is advocating for.

How can the textile services industry contribute to achieving circular economy in the textile industry?
Elena Lai:
The business model of textile services is inherently circular. By having a business model which is focused on renting and reusing textiles we can see a litany of benefits that it can offer to the EU’s Circular Economy Action Plan. Firstly, in renting textiles. Through rented textile services, textile service companies can extend the lifecycle of products and thus reduce the amount of production that is necessary to occur in the first place, while also reducing the amount of wastewater and energy needed in the laundry process. Secondly, through re-use and repair textile products can remain in consumer hands for longer, which is paramount as our industry is one that battles against planned obsolescence. Both of these are important pillars to our industries that will help both consumers and the planet. Lastly, by continuing to expand recycling and upcycling we can minimise waste, ensuring that a product stays inside the European economy as long as possible. These are all important steps and help us do our part to help Europe reach its emissions and sustainability goals.

Textile recycling is a very important point. How do you think the textile recycling rate can be increased?
Elena Lai:
The Commission will mandate separate waste sorting of textiles by the year 2025, thus recycling, upcycling and end of life re-use must be improved. A ban on the burning of unused textiles will also soon take effect, this will incentivise further recycling and waste reduction. Fundamentally what we in textiles services need to do is to continue to reduce, re-use and recycle. We can increase the rate of recycling by making consumers aware of rented textiles and textile services so to increase the public demand for such services.

How can sustainability in textile services be further improved?
Elena Lai:
In order to boost sustainability in our industry we need to build on the existing culture of innovation and entrepreneurship where exciting, new, out-of-the-box ideas can be developed and refined. EU programs like Horizon Europe, which emphasise green and digital solutions to common problems are an excellent way to empower citizens, textile service firms and local communities to take the initiative and take matters into their own hands. The EU’s Due Diligence legislation is one example of somewhere we can see both consumers and firms come together and take proactive action to improve sustainability, not only in textiles and textile services, but in European industry more broadly. To put it clearly, we have to strengthen our technological innovation while also empowering consumers, authorities and textile service firms, we believe our work at the EU level helps to make this a reality.

How does ETSA promote new projects in the field of sustainability?
Elena Lai:
We at ETSA have been hard at work lobbying EU policymakers for responsible legislation, while also spreading awareness of the industry’s best practice to the public. Recently ETSA has also become an EU Commission Climate Pact Ambassador. This is an exciting opportunity which will allow ETSA to work closely with European Institutions to inform and inspire real climate action amongst our members, national associations and the industry as a whole. ETSA is a platform where stakeholders, citizens, industries and European Union representatives can come together and have a dialogue on the best ways to improve Europe’s sustainability. Furthermore, we have been hard at work disseminating information on the best practice that will help Europe get to 55% emissions reductions, as well information on chemicals, waste-water, microplastics and other salient environmental issues. Our work is far from being done but we look forward to continuing to strive and advance via our focused Working Group on Environment and our webinars to make the world green and sustainable again.

What role will circular economy/sustainability play at Texcare?
Elena Lai:
A central role, several European and World Leaders have underlined, is that Climate Change is the most important issue of our time and it is imperative we act now. Climate Change is also an issue with a global spill over and therefore we all have a clear incentive to find solutions and work in synergy with each other. We need future-oriented dialogue which understands the urgent need for sustainability across the entire textile value chain. ETSA in synergy with one of our members, DTV, is working hard to put together a panel at Texcare dedicated to the sustainability debate, with lots of members and participants to get engaged.

What does ETSA expect from this year's Texcare?
Elena Lai:
We at ETSA are excited to be at Texcare, we think it’s a great opportunity to not only network and converse with other relevant actors in the industry but also to share best practice, concerns and most of all opportunities. Due to the pandemic we had a difficult year 2021 and this event will really enhance a stronger engagement of key actors in this sector. The need for green, sustainable and digital solutions is nonetheless imperative. We are looking forward to hearing of ways that the industry across the world not only continues to adapt to the evolving COVID situation, but also how it is embracing the green and digital transition that has been emphasised as being the futuristic approach by our EU policymakers. We at ETSA wholeheartedly look forward to this event.

Texcare International will take place from November 27 December 1, 2021 in Frankfurt am Main.

Air, Water, Oil: What PLA bioplastic can filter well - and what not

Air filters have been discussed so often in recent days in the fight against the pandemic. With filter material made of nonwoven fabric, they block the way back into rooms for aerosols containing viruses. But how can these devices not only protect health, but also be operated with filter material that is as environmentally friendly as possible?

Air filters have been discussed so often in recent days in the fight against the pandemic. With filter material made of nonwoven fabric, they block the way back into rooms for aerosols containing viruses. But how can these devices not only protect health, but also be operated with filter material that is as environmentally friendly as possible?

Under clearly defined conditions, the bioplastic polylactide (PLA), also known as polylactic acid, is suited for this purpose. This can be deduced from results obtained by researchers from the Zuse community in the recently completed "BioFilter" research project. The key question for this and other potential applications of biofilters is: How do the special properties of PLA affect the filter performance and durability? After all, PLA can have practical disadvantages compared to its fossil-based competitors. Its material tends to be brittle and it doesn't particularly like high temperatures beyond 60 degrees Celsius. As a biogenic material, polylactic acid is also potentially more susceptible to abrasion and organic degradation processes. This can play an even greater role in the use of filters, e.g. in sewage treatment facilities, than in air filters. Industrial customers, however, naturally want a durable, reliable product.

From monofilament to nonwoven
Against this background, the researchers studied the PLA properties in order to test nonwovens for biofilters on this basis. The German Textile Research Center North-West (German Textile Research Center North-West - DTNW) and the Saxon Textile Research Institute (STFI), where the nonwovens were produced, were involved. Granules from various commercially available manufacturers were used. However, the research did not start with nonwovens, in which the fibers are deposited close together in different layers, but with so-called monofilaments, i.e. fibers made of PLA that are comparable to threads. DTNW and STFI initially carried out tests on these monofilaments, e.g. in a climate chamber for aging and durability.

As can be seen in the picture, the monofilaments became brittle after only two weeks at higher temperatures from 70 degrees Celsius, as the DTNW authors recently reported in the Journal Applied Polymer Materials. Under normalized conditions, however, the monofilaments showed no measurable reduction in stability even after almost three years, and the PLA nonwovens were in no way inferior to their fossil-based counterparts in terms of filter performance. "In my opinion, the focus for the use of PLA as a filter material will be on applications where relatively low temperatures are present, with which PLA copes very well," says DTNW scientist Christina Schippers.

Besides temperature and humidity consider other factors
For the researchers, however, the project, which was funded by the German Federal Ministry for Economic Affairs and Energy, was not just about the suitability of polylactide for air filters, but also for other applications, such as filtering water. In addition, the research revealed that when evaluating filter media made from bio-based and biodegradable nonwovens, it is important to consider other influencing factors, such as mechanical loads caused by air currents, in addition to temperature and humidity. "The innovative core of the project was to evaluate the possibilities and application limits of PLA nonwovens as filter media with sufficient mechanical properties and long-term stability," says project leader Dr. Larisa Tsarkova. Like her colleagues at STFI, DTNW is involved in the Zuse Community's Bioeconomy Cluster, in which researchers from nonprofit institutes cooperate under the guiding principle of "Researching with Nature." "For us, the bioeconomy is a top cross-industry topic that connects numerous institutes of the Zuse Community and is lived through collaborations such as with the 'Bio-Filter'," explains the future STFI managing director Dr. Heike Illing-Günther.

Cooperation in the Bioeconomy Cluster
With the results obtained from the "Bio-Filter" project, DTNW and STFI now want to continue working in order to be able to make derivations for clearly described areas of application for PLA nonwoven filters in the future. These possible fields of application extend far beyond room air filters and thus beyond the pandemic. For example, the water-repellent property of PLA is potentially interesting for filters in large-scale kitchens for water-oil filtration or also in the industry for engine oils.

The research is also so important, because PLA is already quite well established in individual consumer-related segments - keyword: carrier bags. Traditionally, lactic acid was used to preserve food, for example in sauerkraut. Today, PLA is obtained via a multi-stage synthesis from sugar, which ferments to lactic acid and polymerizes this to PLA, as Kunststoffe.de explains. PLA is one of the best-known bioplastics, but has not always been readily available due to strong demand in recent years. The Netherlands-based company Total Corbion has announced plans to start up a PLA plant with an annual capacity of 100,000 tons in Grandpuits, France, by 2024. It would be the largest plant of its kind in Europe, with Asia leading the way so far.

Innovative wound care: Customized wound dressings made from tropoelastin

Customized, biomedically applicable materials based on tropoelastin are being developed in a joint project by Skinomics GmbH from Halle, Martin Luther University Halle-Wittenberg and the Fraunhofer Institute for Microstructure of Materials and Systems IMWS. The material combines biocompatibility, durability, biodegradability and favorable mechanical properties similar to those of skin. Preclinical tests have confirmed that it is suitable for use as a wound dressing material used in the treatment of chronic and complex wounds.

Customized, biomedically applicable materials based on tropoelastin are being developed in a joint project by Skinomics GmbH from Halle, Martin Luther University Halle-Wittenberg and the Fraunhofer Institute for Microstructure of Materials and Systems IMWS. The material combines biocompatibility, durability, biodegradability and favorable mechanical properties similar to those of skin. Preclinical tests have confirmed that it is suitable for use as a wound dressing material used in the treatment of chronic and complex wounds.

Particularly in the context of an aging society, special wound dressings are gaining in importance. The treatment of complex wound diseases such as venous ulcers, leg ulcers, or foot ulcers is challenging for medical staff, long-term and painful for those affected and cost-intensive for the healthcare system. Innovative protein-based materials are now being used for the treatment of such wounds. However, since they are made from animal tissues, they carry increased risks of infection or can result in undesirable immune reactions. In addition, there are increasing reservations in the population about medical products of animal origin.

In the joint research project, the project partners are currently developing customized, biomedically applicable materials based on human tropoelastin. This precursor protein is converted in the body to elastin, a vital and long-lived structural biopolymer that has exceptional mechanical properties and thus gives the skin and other organs the elasticity and resilience they need to function.

“Elastin is chemically and enzymatically extremely stable, biocompatible and does not produce immunological rejections when used as a biomaterial in humans. Therefore, we want to create new and innovative solutions for the treatment of complex wounds based on human tropoelastin,” says Dr. Christian Schmelzer, Head of the Department of Biological and Macromolecular Materials at Fraunhofer IMWS.

Individual wound treatment
As part of the research project led by Prof. Dr. Markus Pietzsch of Martin Luther University Halle-Wittenberg, the researchers succeeded in developing a biotechnological process for modifying tropoelastin. The modified tropoelastin is processed at Fraunhofer IMWS. Here, an electrospinning procedure is used to produce ultra-thin nanofibers with diameters of only a few hundred nanometers. The resulting nonwovens are further crosslinked to stabilize them for the respective application. The procedures developed have been optimized so that biomedical parameters such as pore size, stability and mechanical properties are variable and can thus be customized to meet the requirements of the respective wound treatment. The materials produced using the new procedures are being investigated by Skinomics GmbH in initial preclinical tests with regard to their skin compatibility and have already achieved promising results.

At the end of the project by the end of this year, applications for intellectual property rights are to be filed, building the basis for a subsequent product development phase for certified medical products.

Stand-up paddle board made from renewable lightweight mater

Stand-up paddling has become a popular sport. However, conventional surfboards are made of petroleum-based materials such as epoxy resin and polyurethane.

Researchers at the Fraunhofer Institute for Wood Research, Wilhelm-Klauditz-Institut, WKI, want to replace plastic boards with sustainable sports equipment: They are developing a stand-up paddle board that is made from one hundred percent renewable raw materials. The ecological lightweight material can be used in many ways, such as in the construction of buildings, cars and ships.

Stand-up paddling has become a popular sport. However, conventional surfboards are made of petroleum-based materials such as epoxy resin and polyurethane.

Researchers at the Fraunhofer Institute for Wood Research, Wilhelm-Klauditz-Institut, WKI, want to replace plastic boards with sustainable sports equipment: They are developing a stand-up paddle board that is made from one hundred percent renewable raw materials. The ecological lightweight material can be used in many ways, such as in the construction of buildings, cars and ships.

Stand-up paddling (SUP) is a sport that is close to nature, but the plastic boards are anything but environmentally friendly. As a rule, petroleum-based materials such as epoxy resin, polyester resin, polyurethane and expanded or extruded polystyrene are used in combination with fiberglass and carbon fiber fabrics to produce the sports equipment. In many parts of the world, these plastics are not recycled, let alone disposed of correctly. Large quantities of plastic end up in the sea and collect in huge ocean eddies. For Christoph Pöhler, a scientist at Fraunhofer WKI and an avid stand-up paddler, this prompted him to think about a sustainable alternative. In the ecoSUP project, he is driving the development of a stand-up paddle board that is made from 100 percent renewable raw materials and which is also particularly strong and durable. The project is funded by the German Federal Ministry of Education and Research (BMBF). The Fraunhofer Center for International Management and Knowledge Economy IMW is accompanying the research work, with TU Braunschweig acting as project partner.

Recovering balsa wood from rotor blades
“In standard boards, a polystyrene core, which we know as styrofoam, is reinforced with fiberglass and sealed with an epoxy resin. We, instead, use bio-based lightweight material,” says the civil engineer. Pöhler and his colleagues use recycled balsa wood for the core. This has a very low density, i.e. it is light yet mechanically stressable. Balsa wood grows mainly in Papua New Guinea and Ecuador, where it has been used in large quantities in wind turbines for many years – up to six cubic meters of the material can be found in a rotor blade. Many of the systems are currently being disconnected from the grid. In 2020 alone, 6000 were dismantled. A large proportion of this is burnt. It would make more sense to recover the material from the rotor blade and recycle it in accordance with the circular economy. “This was exactly our thinking. The valuable wood is too good to burn,” says Pöhler.

Since the entire sandwich material used in conventional boards is to be completely replaced, the shell of the ecological board is also made from one hundred percent bio-based polymer. It is reinforced with flax fibers grown in Europe, which are characterized by very good mechanical properties. To pull the shell over the balsa wood core, Pöhler and his team use the hand lay-up and vacuum infusion processes. Feasibility studies are still underway to determine the optimal method. The first demonstrator of the ecological board should be available by the end of 2022. “In the interests of environmental protection and resource conservation, we want to use natural fibers and bio-based polymers wherever it is technically possible. In many places, GFRP is used even though a bio-based counterpart could do the same,” Pöhler sums up.

Patented technology for the production of wood foam
But how is it possible to recover the balsa wood from the rotor blade — after all, it is firmly bonded to the glass-fiber reinforced plastic (GFRP) of the outer shell? First, the wood is separated from the composite material in an impact mill. The density differences can be used to split the mixed-material structures into their individual components using a wind sifter. The balsa wood fibers, which are available as chips and fragments, are then finely ground. “We need this very fine starting material to produce wood foam. Fraunhofer WKI has a patented technology for this,” explains the researcher. In this process, the wood particles are suspended to form a kind of cake batter and processed into a light yet firm wood foam that holds together thanks to the wood’s own binding forces. The addition of adhesive is not required. The density and strength of the foam can be adjusted. “This is important because the density should not be too high. Otherwise, the stand-up paddle board would be too heavy to transport.”

Initially, the researchers are focusing on stand-up paddle boards. However, the hybrid material is also suitable for all other boards, such as skateboards. The future range of applications is broad: For example, it could be used as a facade element in the thermal insulation of buildings. The technology can also be used in the construction of vehicles, ships and trains.
