MIT researchers developed a fiber computer and networked several of them into a garment that learns to identify physical activities.

What if the clothes you wear could care for your health?
MIT researchers have developed an autonomous programmable computer in the form of an elastic fiber, which could monitor health conditions and physical activity, alerting the wearer to potential health risks in real-time. Clothing containing the fiber computer was comfortable and machine washable, and the fibers were nearly imperceptible to the wearer, the researchers report.

Unlike on-body monitoring systems known as “wearables,” which are located at a single point like the chest, wrist, or finger, fabrics and apparel have an advantage of being in contact with large areas of the body close to vital organs. As such, they present a unique opportunity to measure and understand human physiology and health.
The fiber computer contains a series of microdevices, including sensors, a microcontroller, digital memory, bluetooth modules, optical communications, and a battery, making up all the necessary components of a computer in a single elastic fiber.

The researchers added four fiber computers to a top and a pair of leggings, with the fibers running along each limb. In their experiments, each independently programmable fiber computer operated a machine-learning model that was trained to autonomously recognize exercises performed by the wearer, resulting in an average accuracy of about 70 percent.

Surprisingly, once the researchers allowed the individual fiber computers to communicate among themselves, their collective accuracy increased to nearly 95 percent.
“Our bodies broadcast gigabytes of data through the skin every second in the form of heat, sound, biochemicals, electrical potentials, and light, all of which carry information about our activities, emotions, and health. Unfortunately, most — if not all — of it gets absorbed and then lost in the clothes we wear. Wouldn’t it be great if we could teach clothes to capture, analyze, store, and communicate this important information in the form of valuable health and activity insights?” says Yoel Fink, a professor of materials science and engineering at MIT, a principal investigator in the Research Laboratory of Electronics (RLE) and the Institute for Soldier Nanotechnologies (ISN), and senior author of a paper on the research, which has been published in Nature.

The use of the fiber computer to understand health conditions and help prevent injury will soon undergo a significant real-world test as well. U.S. Army and Navy service members will be conducting a monthlong winter research mission to the Arctic, covering 1,000 kilometers in average temperatures of -40 degrees Fahrenheit. Dozens of base layer merino mesh shirts with fiber computers will be providing real-time information on the health and activity of the individuals participating on this mission, called Musk Ox II.

“In the not-too-distant future, fiber computers will allow us to run apps and get valuable health care and safety services from simple everyday apparel. We are excited to see glimpses of this future in the upcoming Arctic mission through our partners in the U.S. Army, Navy, and DARPA. Helping to keep our service members safe in the harshest environments is a honor and privilege,” Fink says.

He is joined on the paper by co-lead authors Nikhil Gupta, an MIT materials science and engineering graduate student; Henry Cheung MEng ’23; and Syamantak Payra ’22, currently a graduate student at Stanford University; John Joannopoulos, the Francis Wright Professor of Physics at MIT and director of the Institute for Soldier Nanotechnologies; as well as others at MIT, Rhode Island School of Design, and Brown University.

Fiber focus
The fiber computer builds on more than a decade of work in the Fibers@MIT lab at the RLE and was supported primarily by ISN. In previous papers, the researchers demonstrated methods for incorporating semiconductor devices, optical diodes, memory units, elastic electrical contacts, and sensors into fibers that could be formed into fabrics and garments.

“But we hit a wall in terms of the complexity of the devices we could incorporate into the fiber because of how we were making it. We had to rethink the whole process. At the same time, we wanted to make it elastic and flexible so it would match the properties of traditional fabrics,” says Gupta.
 
One of the challenges that researchers surmounted is the geometric mismatch between a cylindrical fiber and a planar chip. Connecting wires to small, conductive areas, known as pads, on the outside of each planar microdevice proved to be difficult and prone to failure because complex microdevices have many pads, making it increasingly difficult to find room to attach each wire reliably.

In this new design, the researchers map the 2D pad alignment of each microdevice to a 3D layout using a flexible circuit board called an interposer, which they wrapped into a cylinder. They call this the “maki” design. Then, they attach four separate wires to the sides of the “maki” roll and connected all the components together.
“This advance was crucial for us in terms of being able to incorporate higher functionality computing elements, like the microcontroller and Bluetooth sensor, into the fiber,” says Gupta.

This versatile folding technique could be used with a variety of microelectronic devices, enabling them to incorporate additional functionality.

In addition, the researchers fabricated the new fiber computer using a type of thermoplastic elastomer that is several times more flexible than the thermoplastics they used previously. This material enabled them to form a machine-washable, elastic fiber that can stretch more than 60 percent without failure.

They fabricate the fiber computer using a thermal draw process that the Fibers@MIT group pioneered in the early 2000s. The process involves creating a macroscopic version of the fiber computer, called a preform, that contains each connected microdevice.

This preform is hung in a furnace, melted, and pulled down to form a fiber, which also contains embedded lithium-ion batteries so it can power itself.
“A former group member, Juliette Marion, figured out how to create elastic conductors, so even when you stretch the fiber, the conductors don’t break. We can maintain functionality while stretching it, which is crucial for processes like knitting, but also for clothes in general,” Gupta says.

Bring out the vote
Once the fiber computer is fabricated, the researchers use a braiding technique to cover the fiber with traditional yarns, such as polyester, merino wool, nylon, and even silk.

In addition to gathering data on the human body using sensors, each fiber computer incorporates LEDs and light sensors that enable multiple fibers in one garment to communicate, creating a textile network that can perform computation.

Each fiber computer also includes a Bluetooth communication system to send data wirelessly to a device like a smartphone, which can be read by a user.

The researchers leveraged these communication systems to create a textile network by sewing four fiber computers into a garment, one in each sleeve. Each fiber ran an independent neural network that was trained to identify exercises like squats, planks, arm circles, and lunges.

“What we found is that the ability of a fiber computer to identify human activity was only about 70 percent accurate when located on a single limb, the arms or legs.
However, when we allowed the fibers sitting on all four limbs to ‘vote,’ they collectively reached nearly 95 percent accuracy, demonstrating the importance of residing on multiple body areas and forming a network between autonomous fiber computers that does not need wires and interconnects,” Fink says.

Moving forward, the researchers want to use the interposer technique to incorporate additional microdevices.

Arctic insights
In February, a multinational team equipped with computing fabrics will travel for 30 days and 1,000 kilometers in the Arctic. The fabrics will help keep the team safe, and set the stage for future physiological “digital twinning” models.

“As a leader with more than a decade of Arctic operational experience, one of my main concerns is how to keep my team safe from debilitating cold weather injuries — a primary threat to operators in the extreme cold,” says U.S. Army Major Mathew Hefner, the commander of Musk Ox II. “Conventional systems just don’t provide me with a complete picture. We will be wearing the base layer computing fabrics on us 24/7 to help us better understand the body’s response to extreme cold and ultimately predict and prevent injury.”
 
Karl Friedl, U.S. Army Research Institute of Environmental Medicine senior research scientist of performance physiology, noted that the MIT programmable computing fabric technology may become a “gamechanger for everyday lives.”

“Imagine near-term fiber computers in fabrics and apparel that sense and respond to the environment and to the physiological status of the individual, increasing comfort and performance, providing real-time health monitoring and providing protection against external threats. Soldiers will be the early adopters and beneficiaries of this new technology, integrated with AI systems using predictive physiological models and mission-relevant tools to enhance survivability in austere environments,” Friedl says.

“The convergence of classical fibers and fabrics with computation and machine learning has only begun. We are exploring this exciting future not only through research and field testing, but importantly in an MIT Department of Materials Science and Engineering course ‘Computing Fabrics,’ taught with Professor Anais Missakian from the Rhode Island School of Design,” adds Fink.

This research was supported, in part, by the U.S. Army Research Office Institute for Soldier Nanotechnology (ISN), the U.S. Defense Threat Reduction Agency, the U.S. National Science Foundation, the Fannie and John Hertz Foundation Fellowship, the Paul and Daisy Soros Foundation Fellowship for New Americans, the Stanford-Knight Hennessy Scholars Program, and the Astronaut Scholarship Foundation.

Price pressure, reluctance to buy and changing demands on the longevity of products. Retailers around the world are facing similar challenges. Heimtextil Trends 25/26, curated by the Milan-based design platform Alcova, consciously addresses these challenges and provides valuable inspiration and conclusive solutions. Visitors will find these in the Trend Arena in Hall 3.0 at Heimtextil from 14 to 17 January 2025.

With its three themes - ‘Naturally Uneven’, ‘Radically Restructured’ and ‘Regenerative’ - Heimtextil Trends 25/26 focuses on key values such as integrity, longevity and ecological awareness. These themes reflect what is becoming increasingly important to customers: Products that not only impress with their aesthetics, but also fulfil ethical and ecological requirements. These approaches can be experienced live in the Trend Arena - from material qualities and colours to innovative production processes. Retailers will be given concrete inspiration and tools to orientate their product range towards more conscious consumption. After all, consumers' purchasing decisions are clear: long-lasting, highquality products that are also produced in a socially and environmentally responsible way are very popular. A recent study conducted by IFH on behalf of Messe Frankfurt confirms this. Consumers are becoming increasingly selective and weigh things up carefully before making a purchase decision. When they decide in favour of a product, it must be convincing in all areas: durable, high quality - but also sustainable. After all, the majority of Europeans attach great importance to sustainability when it comes to home textiles. Aspects such as long-lasting products, recyclable materials and transparency are among the key criteria.

The beauty of the imperfect: ‘Naturally Uneven’
‘Naturally Uneven’ celebrates the rawness and authenticity of natural materials. Fabrics such as linen, hemp, jute and wool stand for organic structures and handmade perfection in the imperfect. Small imperfections and natural grains make each piece unique and tell stories of craftsmanship and originality. The colour palette emphasises this natural aesthetic: soft grey like untreated stone, unbleached fibre tones and the delicate ‘Rose of Permanence’, which symbolises down-to-earthness and timelessness.

Innovation meets sustainability: ‘Radically Restructured’
This theme shows how advanced technologies and environmentally conscious design merge. The focus is on recycled materials that minimise the consumption of resources and set new standards in textile production. Heavy and light, transparent and opaque - these contrasts create a fascinating interplay of structure and appearance. In terms of colour, bold shades such as ‘End of Petrol’ and ‘New Green Deal’ dominate, visualising the upheaval. Techniques such as 3D weaving, digital printing and laser cutting reflect the innovative power that characterises this approach.

Redefining circular thinking: ‘Regenerative’
‘Regenerative’ embodies the principles of renewal, growth and circularity for customers who want to help shape a more sustainable future. Here you will find a mix of natural, recycled and bio-based fibres from linen, hemp and recycled wool to textiles that have been upcycled or reused. Handcrafted elements and techniques underline the focus on imperfection and individuality, while colours such as ‘Regenerative Azure’ or ‘Repairable Green’ convey the theme in all its many facets.

Textile Exchange launched the first Materials Market Report in 2013 as a comprehensive, annual publication that provides unique data and insights into global fiber and raw materials production.

The Materials Market Report shares best available data on global fibre and material production volumes alongside program-specific volumes and other insights such as the number of certified sites. For the purpose of this report, leather, rubber, and down are considered non-fibre raw materials and are therefore included separately from the section and charts on ‘global fibre’.

It helps inform the textile industry’s efforts to reduce emissions associated with raw material production in line with a 1.5-degree temperature rise pathway. The report highlights the urgency to accelerate the transition to fibres from preferred sources, intensify efforts to significantly reduce reliance on virgin fossil-based materials, and invest in strategies that separate value creation from the need for extracting new materials.

It’s important to note that the compilation of global market data for fibres and raw materials is challenging and the quality of available data is often limited. The collection of primary data from suppliers is beyond the scope of this report so Textile Exchange relies on secondary data from industry associations, international organizations, governmental organizations, standard setters, and research institutes.

While Textile Exchange has collected, analysed, and compiled this information in all good conscience and has cross-checked it wherever possible, the report is intended for general guidance and information purposes only. Data gaps and inconsistencies are common in global market data, so modelling has often had to be applied.

Global fibre production reached an all-time high of 124 million tonnes in 2023, according to the latest Materials Market Report– which looks at total volumes used for apparel, home textiles, footwear, or any other application.

The data shows that the market share of virgin fossil-based synthetics continued to increase in 2023, with a decline in that of cotton and recycled fibres. Other key takeaways from the report’s data include:

• Record fibre production: Despite industry efforts, global fibre production has more than doubled since 2000. The last year’s 124 million tonnes represents a 7% increase from 116 million tonnes in 2022, and is expected to rise to 160 million tonnes in 2030 if current trends continue.
• Synthetics continue to dominate: The production of virgin fossil-based synthetic fibres increased from 67 million tonnes in 2022 to 75 million tonnes in 2023. Polyester remained the most produced fibre globally, accounting for 57% of total fibre production.
• Recycled synthetics face challenges: Although recycled polyester fibre production slightly increased in 2023, the overall market share of recycled polyester decreased from 13.6% to 12.5%. For polyamide (nylon), the second most used synthetic fibre, recycled fibres constituted only 2% of the total market share. These trends are attributed to the lower prices and continued production of virgin synthetics, as well as current limitations in recycling technologies. Less than 1% of the global fibre market came from pre- and post-consumer recycled textiles.
  
  The combined share of all recycled fibres slightly decreased in 2023, from around 7.9% to 7.7%, mainly due to an increase in the production of fossil-based polyester, which had lower prices than recycled polyester. Fossil based synthetics production increased from 67 million tonnes in 2022 to 75 million tonnes in 2023. Meanwhile, less than 1% of the global fibre market came from pre- and post-consumer recycled textiles.
• Cotton production saw a slight decline: Total global cotton volumes fell slightly from 25.1 million tonnes in 2022 to 24.4 million tonnes in 2023. However, the share of cotton produced under sustainability programs remained stable, accounting for 29% of all cotton produced.
• Certified wool climbs: Data showed positive trends for wool produced under standards such as the Responsible Wool Standard (RWS), ZQ, SustainaWOOL (GREEN and GOLD), Sustainable Cape Wool Standard (SCWS) and Climate Beneficial programs. This increased from 4.2% in 2022 to 4.8% in 2023. Recycled wool continued to account for around 6% of the global wool market.
• Certified mohair and cashmere reached almost half of market share: Certified fibres such as mohair and cashmere saw notable growth, both with market shares of 47%.
• Manmade cellulosic fibres production increased: Overall MMCF production increased from 7.4 million tonnes in 2022 to 7.9 million tonnes in 2023, representing 6% of the global fibre market.

The report highlights a continued reliance on new virgin fossil-based synthetic materials, threatening to undermine the industry’s commitments to its climate goals. It also shows the current limitations of textile-to-textile recycling and an urgent need for innovative solutions, with most recycled polyester still coming from PET bottles.

Amid these concerns, one positive trend that stands out is the increased industry demand for responsible animal fibres through programs like the Responsible Mohair Standard (RMS) and Responsible Alpaca Standard (RAS), both contributing to better animal welfare and environmental management. This indicates the potential of farm-level standards of this kind to increase market recognition of more sustainable practices on the ground.

“We hope this data serves as a clear call to action for the industry, highlighting both the successes and the critical areas where we must intensify our focus to meet climate targets,” said Claire Bergkamp, CEO of Textile Exchange.

“Unlocking textile-to-textile recycling pathways will be essential to reducing reliance on virgin synthetics. Equally important is continuing to support those on the ground who are driving the transition from conventional systems to preferred materials. It is more urgent than ever to support those who have already invested in preferred systems, while also enabling the transition away from conventional at scale.”

Tufts researchers harness protein from silk to make virus-sensing gloves, surgical screws that dissolve in your body, and other next-generation biomedical materials

About a mile northwest of Tufts’ Medford/Somerville campus, on the fourth floor of a refurbished woolen factory, there is a shrine to silk. Glass vases filled with silkworm cocoons and washed silk fibers sit artfully on a shelf across from a colorful drawing of the life cycle of Bombyx mori, the domesticated silk moth. Farther in, more cocoons in wall-mounted cases border a large, close-up image of silk fibers, and displays hold dozens of prototypes made from silk, including smart fabrics, biosensors, a helmet that changes color upon impact, and potential replacements for materials like leather, plastic, and particle board.

The only things missing are the silkworms themselves, but Fiorenzo Omenetto, the director of Silklab and the Frank C. Doble Professor of Engineering at Tufts, said they will be arriving soon. The lab is building a terrarium so that visitors can view the animals.
“We’re going to have a celebration of silkworms and moths,” Omenetto said.

Silk has been cultivated and harvested for thousands of years. It is best known for the strong, shimmering fabric that can be woven from its fibers, but it also has a long history of use in medicine to dress injuries and suture wounds. At Silklab, Omenetto and his colleagues are building on silk’s legacy, proving that this ancient fiber could help create the next generation of biomedical materials.

Silk moth caterpillars, known as silkworms, extrude a single sticky strand of silk from their mouths to form cocoons, which are harvested by silk farmers to make silk thread. At its core, silk is a mixture of two proteins: fibroin, which provides the fiber’s structure, and sericin, which binds it together. With a few steps in the lab, Tufts researchers can remove the sericin and dissolve the fibers, turning a dry cocoon into a fibroin-filled liquid.

“Nature builds structural proteins that are very tough and very strong,” Omenetto said. “Your bricks are these fibroin proteins floating in water. From there, you can build whatever you want.”
Starting with shipments of dried cocoons from silk farms, Omenetto and his colleagues have been able to create gels, sponges, clear plastic-like sheets, printable inks, solids that look like amber, dippable coatings, and much more.

“Each of the materials that you make can contain all these different functions, and there’s only 24 hours in a day,” Omenetto said with a laugh. “This is why I don’t sleep.”

Biocompatible and Biodegradable
When Omenetto arrived at Tufts almost two decades ago, his research was focused on lasers and optics—silk wasn’t in the picture. But a chance conversation with David Kaplan, the Stern Family Professor of Engineering and chair of the biomedical engineering department, set him on a new path.

Kaplan, who has been working with silk since the early ’90s, was designing a silk scaffold that would help rebuild a person’s cornea, allowing cells to grow between the layers. He needed a way to ensure that the growing cells would have enough oxygen and showed the small, transparent sheet to Omenetto, who was immediately intrigued by the material. Omenetto was able to use his lab’s lasers to put tiny holes in Kaplan’s silk cornea. More collaborations quickly followed.
“We’ve worked together incessantly since then,” Kaplan said.

One of those lines of research has been finding ways to use silk to help repair and regrow bone, blood vessels, nerves, and other tissue. Silk is biocompatible, meaning it doesn’t cause harm in the body and breaks down in predictable ways. With the right preparation, silk materials can provide necessary strength and structure while the body is healing.

“You can mold and shape silk to whatever you need, and it will hold that volume while the native tissue regrows into the space and the silk material degrades,” Kaplan said. “Eventually it’s 100 percent gone, and you’re back to your normal tissue.”

Some of this work has already been approved for use by the U.S. Food and Drug Administration. A company called Sofregen, which spun out of Kaplan and Omenetto’s research, is using an injectable silk-based gel to repair damaged vocal cords, the tissues that regulate air flow and help us speak.

On their own, sturdy silk structures can keep their size, shape, and function for years before degrading. But in some instances, such as those involving surgical screws and plates intended for use in rapidly growing children, this pace would be too slow. The researchers had to find a way to speed up the time it takes for dense silk biomaterials to break down. They introduced an enzyme that our bodies produce naturally into the silk to hasten the breakdown process. The idea is that the enzyme would sit dry and inactive within the silk device until the structure is installed in a person, then the device would hydrate and activate the enzyme to digest the material more rapidly.

“We can titer in just the right amount of enzyme to make a screw go away in a week, a month, a year,” Kaplan said. “We have control over the process.”

Currently, Kaplan and his lab are working on other small, degradable medical devices that would help cut down on the number of surgeries that patients need. Ear tubes, for example, are often surgically implanted to help alleviate chronic ear infections and then need to be surgically removed. Kaplan and his colleagues have designed silk-based ear tubes that degrade on their own and can even carry antibiotics.

“As someone with a daughter who went through six surgeries on her ear, I know how helpful this could be,” Kaplan said.

From the perspective of European consumption, textiles have on average the fourth highest negative life cycle impact on the environment and climate change, after food, housing and mobility. A shift to a circular textile production and consumption system with longer use, and more reuse and recycling could reduce those impacts along with reductions in overall consumption. One important measure is circular design of textiles to improve product durability, repairability and recyclability and to ensure the uptake of secondary raw materials in new products.

Key messages

• In 2019, the EU textile and clothing sector had a turnover of EUR162 billion, employing over 1.5 million people across 160,000 companies. As was the case in many sectors, between 2019 and 2020, the COVID-19 crisis decreased turnover by 9% for textiles as a whole and by 17% for clothing.
• In 2020, textile consumption in Europe had on average the fourth highest impact on the environment and climate change from a global life cycle perspective. It was the consumption area with the third highest impact on water and land use, and the fifth highest in terms of raw material use and greenhouse gas emissions.
• To reduce the environmental impacts of textiles, a shift towards circular business models, including circular design, is crucial. This will need technical, social and business model innovation, as well as behavioural change and policy support.
• Circular design is an important enabler of the transition towards sustainable production and consumption of textiles through circular business models. The design phase plays a critical role in each of the four pathways to achieving a circular textile sector: longevity and durability; optimised resource use; collection and reuse; and recycling and material use.

Textiles are identified as a key value chain in the EU circular economy action plan and will be addressed in the forthcoming European Commission’s 2022 EU strategy for sustainable and circular textiles and EU sustainable products initiative. This briefing aims to improve our understanding of the environmental and climate impacts of textiles from a European perspective and to identify design principles and measures to increase circularity in textiles. It is underpinned by a report from the EEA’s European Topic Centre on Circular Economy and Resource Use available here.

1. Production, trade and consumption of textiles
Textiles is an important sector for the EU economy. In 2019, the EU textile and clothing sector had a turnover of EUR162 billion, employing over 1.5 million people in 160,000 companies. As was the case for many sectors, between 2019 and 2020, the COVID-19 health and economic crisis decreased turnover by 9% for textiles as a whole and by 17% for clothing (Euratex, 2021).

In 2020, 6.9 million tonnes of finished textile products were produced in the EU-27. EU production specialises in carpets, household textiles and other textiles (including non-woven textiles, technical and industrial textiles, ropes and fabrics). In addition to finished products, the EU produces intermediate products for textiles, such as fibres, yarns and fabrics (Köhler et al., 2021).

The textiles sector is labour intensive compared with others. Almost 13 million full-time equivalent workers were employed worldwide in the supply chain to produce the amount of clothing, textiles and footwear consumed in the EU-27 in 2020. This makes the textiles sector the third largest employer worldwide, after food and housing. Most production takes place in Asia, where low production costs come at the expense of workers’ health and safety.
 
Textiles are highly globalised, with Europe being a significant importer and exporter. In 2020, 8.7 million tonnes of finished textile products, with a value of EUR125 billion, were imported into the EU-27. Clothing accounts for 45% of imports in terms of volume, followed by household textiles, other textiles and footwear (Eurostat, 2021a). The EU imports mainly from China, Bangladesh and Turkey, and exports mainly to the United Kingdom, Switzerland and the United States (Euratex, 2020).

Consumption
European households consume large amounts of textile products. In 2019, as in 2018, Europeans spent on average EUR600 on clothing, EUR150 on footwear and EUR70 on household textiles (Köhler et al., 2021; Eurostat, 2021b).

The response to the COVID-19 pandemic, involving stay-at-home measures and the closure of companies and shops, decreased textile production and demand overall (Euratex, 2021). As a result, the consumption of clothing and footwear per person decreased in 2020, relative to 2019, while the consumption of household textiles slightly increased. Average textile consumption per person amounted to 6.0kg of clothing, 6.1kg of household textiles and 2.7kg of shoes in 2020 (see Figure 1).

Apart from this COVID-related drop in consumption in 2020, the estimated consumption of clothing and footwear stayed relatively constant over the last decade, with slight fluctuations between years (see Figure 2). Similarly, the consumption of household textiles was also relatively steady, with a slight increase over the decade.

When calculating the ‘estimated consumption’ based on production and trade data from 2020, and excluding industrial/technical textiles and carpets, total textile consumption is 15kg per person per year, consisting of, on average:

• 6.0kg of clothing
• 6.1kg of household textiles
• 2.7kg footwear.

For 2020, this amounts to a total consumption of 6.6 million tonnes of textile products in Europe. Textile consumption estimates are uncertain, as they vary by study, often using different scopes and calculation methods.

2. Environmental and climate impacts of textiles
The production and consumption of textiles has significant impacts on the environment and climate change. Environmental impacts in the production phase result from the cultivation and production of natural fibres such as cotton, hemp and linen (e.g. use of land and water, fertilisers and pesticides) and from the production of synthetic fibres such as polyester and elastane (e.g. energy use, chemical feedstock) (ETC/WMGE, 2021b). Manufacturing textiles requires large amounts of energy and water and uses a variety of chemicals across various production processes. Distribution and retail are responsible for transport emissions and packaging waste.

During use and maintenance — washing, drying and ironing — electricity, water and detergents are used. Chemicals and microfibres are also emitted into the waste water. Meanwhile, textiles contribute to significant amounts of textile waste. At the end of their life, textiles often end up in general waste and are incinerated or landfilled. When textile waste is collected separately, textiles are sorted and reused, recycled or disposed of, depending on their quality and material composition. In 2017, it was estimated that less than 1% of all textiles worldwide are recycled into new products (Ellen MacArthur Foundation, 2017).

To illustrate the magnitude of the impacts of textile consumption on raw material use, water and land use and greenhouse gas emissions compared with other consumption categories, we have updated our calculations of the life cycle environmental and climate impacts in the EU. We used input-output modelling based on data from the Exiobase database and Eurostat. In line with the reduced textile consumption level in 2020 because of the COVID-19 pandemic, the environmental impacts decreased from 2019 to 2020.

Raw material use
Large amounts of raw materials are used for textile production. To produce all clothing, footwear and household textiles purchased by EU households in 2020, an estimated 175 million tonnes of primary raw materials were used, amounting to 391kg per person. Roughly 40% of this is attributable to clothes, 30% to household textiles and 30% to footwear. This ranks textiles as the fifth highest consumption category in Europe in terms of primary raw material use (see Figure 3).

The raw materials used include all types of materials used in producing natural and synthetic fibres, such as fossil fuels, chemicals and fertilisers. It also includes all building materials, minerals and metals used in the construction of production facilities. Transport and retail of the textile products are included as well. Only 20% of these primary raw materials are produced or extracted in Europe, with the remainder extracted outside Europe. This shows the global nature of the textiles value chain and the high dependency of European consumption on imports. This implies that 80% of environmental impacts generated by Europe’s textile consumption takes place outside Europe. For example, cotton farming, fibre production and garment construction mostly take place in Asia (ETC/WMGE, 2019).

Water use
Producing and handling textiles requires large quantities of water. Water use distinguishes between ‘blue’ water (surface water or groundwater consumed or evaporated during irrigation, industry processes or household use) and ‘green’ water (rain water stored in the soil, typically used to grow crops) (Hoekstra et al., 2012).

To produce all clothing, footwear and household textiles purchased by EU households in 2020, about 4,000 million m³ of blue water were required, amounting to 9m³ per person, ranking textiles’ water consumption in third place, after food and recreation and culture (see Figure 4).

Additionally, about 20,000 million m³ of green water was used, mainly for producing cotton, which amounts to 44m³ per person. Blue water is used fairly equally in producing clothing (40%), footwear (30%) and household and other textiles (30%). Green water is mainly consumed in producing clothing (almost 50%) and household textiles (30%), of which cotton production consumes the most.

Water consumption for textiles consumed in Europe mostly takes place outside Europe. It is estimated that producing 1kg of cotton requires about 10m³ of water, typically outside Europe (Chapagain et al., 2006).

Land use
Producing textiles, in particular natural textiles, requires large amounts of land. The land used in the supply chain of textiles purchased by European households in 2020 is estimated at 180,000 km², or 400m² per person. Only 8% of the land used is in Europe. Over 90% of the land use impact occurs outside Europe, mostly related to (cotton) fibre production in China and India (ETC/WMGE, 2019). Animal-based fibres, such as wool, also have a significant land use impact (Lehmann et al., 2018). This makes textiles the sector with the third highest impact on land use, after food and housing (see Figure 5). Of this, 43% is attributable to clothes, 35% to footwear (including leather shoes, which have a high land use impact because of the need for cattle pasture) and 23% to household and other textiles.

Greenhouse gas emissions
The production and consumption of textiles generate greenhouse gas emissions, in particular from resource extraction, production, washing and drying, and waste incineration. In 2020, producing textile products consumed in the EU generated greenhouse gas emissions of 121 million tonnes carbon dioxide equivalent (CO₂e) in total, or 270kg CO₂e per person. This makes textiles the household consumption domain responsible for the fifth largest impact on climate change, after housing, food, transport and mobility, and recreation and culture (see Figure 6). Of this, 50% is attributable to clothes, 30% to household and other textiles, and 20% to footwear. While greenhouse gas emissions have a global effect, almost 75% are released outside Europe, mainly in the important textile-producing regions in Asia (ETC/WMGE, 2019).

About 80% of the total climate change impact of textiles occurs in the production phase. A further 3% occurs in distribution and retail, 14% in the use phase (washing, drying and ironing), and 3% during end of life (collection, sorting, recycling, incineration and disposal) (ECOS, 2021; Östlund et al., 2020).

Textiles made from natural fibres, such as cotton, generally have the lowest climate impact. Those made from synthetic fibres (especially nylon and acrylic) generally have a higher climate impact because of their fossil fuel origin and the energy consumed during production (ETC/WMGE, 2021b; Beton et al., 2014).

3. Design as an enabler of circular business models for textiles
To reduce the environmental and climate change impacts of textiles, shifting towards circular business models is crucial to save on raw materials, energy, water and land use, emissions and waste (ETC/WMGE, 2019). Implementing and scaling circular business models requires technical, social and business model innovation; as well as enablers from policy, consumption and education (EEA, 2021).

Circular design is an important component of circular business models for textiles. It can ensure higher quality, longer lifetimes, better use of materials, and better options for reuse and recycling. While it is important to enable the recycling and reuse of materials, life-extending strategies, such as design for durability, ease of reuse, repair and remanufacturing, should be prioritised. Preventing the use of hazardous chemicals and limiting toxic emissions and release of microplastics at all life cycle stages should be incorporated into product design.

Designing for circularity is the most recent development in design for sustainability. Expanding a technical and product-centric focus to a focus on large-scale system-level changes (considering both production and consumption systems) shows that this latest development requires many more disciplines than traditional engineering design. Product design as a component of a circular business model depends on consumer behaviour and policy to realise its potential and enable implementation. Figure 7 shows the linkages between the circular business model, product design, consumer behaviour and policy. All are needed to slow down and close the loop, making it circular.

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?

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.

The interview was conducted by Ines Chucholowius, Managing partner Textination GmbH

With her textile project "kunst.werke" [art.works], artist Britta Schatton draws attention to Thuringia's diverse art and cultural landscape. Together with photographer Marcel Krummrich, she portrays nine members of the Thuringian art world. The decisive and binding accessory is a hand-dyed and hand-printed scarf made of merino wool-silk-felt, that is individually produced for each artist - each unique piece is created from the personal perception of the respective wearer.

The pandemic has forced many artists to look for another, a virtual audience, due to the restrictions. This was not always successful. Therefore, it is part of the project to give all portrayed a voice about their personal situation in the time determined by Corona. These statements are to be heard on virtual stages.

Britta Schatton emphasizes: “We all share the basic need to regularly experience and create art and culture as an integral part of life - even in times of pandemic. People need art - art needs people. Especially in pandemic times, when art and culture are increasingly threatened existentially."

The freelance artist prefers to work with felt and has completed her education at the Filzschule Oberrot in Baden-Württemberg under the guidance of Inge Bauer, Beatriz Schaaf-Giesser and Lyda Rump. Since 2012, qualifications with national and international textile artists such as Liz Clay (GB), Pam de Groot (AU), Britta Ankenbauer (DE), Ricarda Aßmann (DE) and Ute Herre (DE) followed. In 2014 she became a member of the artist group TAT Textil Art Thüringen.
          
In 2021, she received a special grant from the Free State of Thuringia for the "kunst.werke" project and was assigned to design the honorary awards for the Bundesgartenschau (Federal Garden Show), which will take place in Erfurt in 2021.

An exhibition of the portraits can be seen in the store gallery ARTenVielfalt of Britta Schatton in Erfurt. Part of the revenue from the sale of the scarves and loops from the limited series will be used to support an institution for the promotion of youth art.

As a result of the Corona pandemic, the PERFORMANCE DAYS fair on December 9^th - 10^th and the accompanying sustain&innovate conference for sustainability on December 10 could only take place in digital form. Nevertheless: exhibitors, visitors and partners can look back on a successful event. The focus topic “Nothing to Waste – Closing the Loop“ relating to the issue of the textile circular economy in the course of the sustain&innovate conference also provided great discussion material while generating a positive response.

The PERFORMANCE DAYS team also expresses its satisfaction. Because despite the event being solely a digital event on the 9^th and 10^th of December 2020, an estimated 15,000 participants made extensive use of the comprehensive online offerings of the 191 digital exhibitors, among them drirelease/OPTIMER, Merryson, Stotz, HeiQ, Schoeller Textil, Long Advance, Dry-Tex, Utenos, Fidlock, Cifra, dekoGraphics and Jia Meir, during the week of the fair. The popular “Contact Supplier” function was supplemented with a new online tool that allows exhibitors to be contacted directly via chat, call or per video. A total of 3,250 fabric sample orders were placed with exhibitors. The variety on offer included fabric innovations for Autumn/Winter 2022/2023 within the top class PERFORMANCE FORUM and an extensive digital supporting program via live-stream with informative webinars, talks and rounds of discussions. Best of all: the resulting videos will be available on demand on the PERFORMANCE DAYS website free of charge.  
 
Finally standard: PERFORMANCE FORUM with sustainable materials
Innovative, sustainable and cutting-edge: the 240 fabrics plus accessory trends at this year’s PERFORMANCE FORUM impressed throughout with exciting environmentally conscious solutions. Natural fibers such as hemp, organic cotton, bamboo, wool or coconut shell remain in demand, while manufacturers are also increasingly refraining from the use of environmentally harmful chemicals, avoiding microplastics, advocating natural dyeing processes and either trying to return fabrics to the cycle, recycle plastic and other waste in order to produce fibres in such a way that they are biodegradable. This environmental awareness is also reflected in this year’s FOCUS TOPIC – so here the 24 best fabrics not only score in terms of sustainability, but also demonstrate that they are both functional and can be returned to the textile cycle, true to the motto “Nothing to Waste – Closing the Loop.   

In the Marketplace section, visitors have the opportunity to view more than 9,500 exhibitor products, including the fabric highlights of the individual categories of the PERFORMANCE FORUMS. In order to be able to digitally present the fabrics to visitors as realistically as possible in terms of feel, design and structure, the Forum has been equipped with innovative 3D technology, including innovative tools such as 3D images, video animations and U3M files for download.  

From fiber to fiber: successful sustain&innovate conference generates discussion  
Textile circular economy is considered part of the solution to the global waste problem, curbing the consumption of resources and reducing climate damaging greenhouse gases. But what exactly is the circular economy and how can it succeed? Most importantly, how far are fiber manufacturers in developing mono-component fabrics that can eventually be returned back into the textile cycle?    
The Focus Topic of this year’s sustainability conference, launched in cooperation with SPORTSFASHION by SAZ, offered a platform for discussion and strove to enlighten with evocative talks, discussion rounds and webinars. Christiane Dolva, Head of Sustainability at Fjällräven, got to the heart of the matter at the start of the expert talks on the second day of the fair, outlining how important emotional consistency is for the brand itself and ultimately also for the consumer – especially when it comes to textile recycling. Durability, good quality, in combination with timeless design are more important than ever today and in the future in terms of sustainable action. Added to this is the possibility of reviving products by means of a repair service. Equally exciting: the development of new technologies in terms of recycling. Erik Bang from the H&M Foundation provided a first glimpse of the new Greenmachine, which should make it possible to separate mixed fabrics such as cotton and polyester as early as 2021. Alternatively, old clothing is converted into new fibres thanks to companies such as WornAgain, Re:newcell, Spinnova or Infinited Fiber, which soon promises to be more than just a mere vision. For those who wish to gain insight into the supply chain of their purchased garment, the start-up know your stuff lets customers track the journey of the respective garment by simply scanning a QR code on the garment in a store or online.    
 
Free extensive retrospective
The next edition of PERFORMANCE DAYS is planned as a hybrid fair and will take place on May 19^th and May 20^th, 2021 in Munich as well as online. Until then, the PERFORMANCE DAYS platform will remain accessible, for instance with the Marketplace and further inspiring topics of (video) material stories to make online sourcing even easier. The talks from the first day of the fair and the conference will be accessible free of charge on the fair website.

TREND REPORT

• Winter sports trends for 2020/2021
• The winter sports industry is increasingly focusing on sustainability
• ISPO Munich (January 26 to 29) to showcase next season’s products

Health will be one of the next decade’s megatrends. The sports industry is, for its part, one of the growth drivers, not least because society now views fitness as a synonym for health. In the future, athleticism will have an ever greater bearing on our everyday lives.

“Medical fitness” refers to ensuring both a sporty lifestyle and the right medical care tailored to the individual needs. Winter sports are also set to assume a challenging yet important role in the future as a vehicle for teaching values within society. Veit Senner, Professor of Sports Equipment and Sports Materials at the Technical University of Munich, says: “Sports must be used as an emotional Trojan Horse for teaching skills and in particular for teaching values.”

There are also other challenges that will need to be faced in the next few years: Children and adolescents need to be encouraged to lead more active lifestyles and our aging population needs to be kept fit and mobile for as long as possible. Senner believes that winter sports could hold the key for today’s youth: “We need to demonstrate the kinds of educational content and values that can be taught through sports.” Attractive products and services therefore need to be created for children. The latest winter sports trends and pro ducts will be showcased at ISPO Munich from January 26 to 29.

Textile manufacturers are giving the winter sports industry an eco-boost
Swedish label Klättermusen impressed the ISPO Award jury so much with its first fully compostable down jacket “Farbaute” that they named it the Gold Winner in the Outdoor category and the winner of the ISPO Sustainability Award.

The first 100% biodegradable down jacket biologically decomposes on the compost heap after around three months (all apart from the zippers and a few snap fasteners which can be removed and reused).

When washed it does not release any microplastics into the environment. Norwegian clothing manufacturer Helly Hansen is launching a new membrane technology for winter 2020/2021 which can be produced without any additional chemicals. The microporous Lifa Infinity membrane is made using a solvent-free process and, together with a water-repellent Lifa outer material, provides extremely impressive protection from the elements. Helly Hansen’s new Lifa Infinity Pro technology also uses the spinning jet dyeing process whereby the color pigments are already injected during the fiber production process. This can save up to 75% water. What’s more, no harmful wastewater is produced.

The winter sports industry is increasingly focusing on sustainability
“The really big trend is for biopolymer fabrics and materials,” says Senner. “The idea is to replace the many different types of plastics that are used in the sports industry with biopolymers.” Together with his team, he is working hard to conduct in-depth research in both areas. This is a trend which French ski brand Rossignol has also identified, whereby it has focused on the use of raw and recycled materials for the production of its new Black Ops Freeride skis. The Black Ops Sender TI model was crowned the winner in its category by the ISPO Award jury.

Alpina Sports is also exploring new ecological avenues and launching a completely sustainable back protector made from 100% sheep’s wool, obtained exclusively from sheep in Switzerland and Norway. The back protector, which consists of three layers of pressed sheep’s wool, meets the standards for protection class 1 and boasts all the impressive properties that the natural material has to offer: In icy temperatures it remains supple, can both warm and cool the wearer, and is odorless. The ISPO Award jury chose Alpina Sports’ “Prolan Vest” as the “Product of the Year”* in the Snowsports Hardware category.

Swedish label Spektrum uses plant-based polymers made from castor oil as well as corn and recycled polyester for its ski and snowboard goggles. The ISPO Award jury was extremely impressed with both the ecological aspects and the execution and named the “Östra Medium” model the Gold Winner.
