Intelligent Textiles as Protection against PAH Toxins

Fraunhofer IWS Supports Industry Partners in the Development of New Protective Suits for Firefighters.
Polycyclic aromatic hydrocarbon (PAHs) are considered harmful to health, especially as potential carcinogens. For example, the molecular compounds of carbon and hydrogen atoms can arise in house fires when mattresses, curtains, wooden beams, plastic, or other objects made of organic materials burn.

Polycyclic Aromatic Hydrocarbons PAH enter the body through the skin and are deposited in fatty tissue. Because the human defense systems are unaware of the ring-shaped carbon compounds, the body does not break down these pollutants – they accumulate and concentrate. This increases the risk of carcinoma over the years. According to “Deutsche Gesetzliche Unfallversicherung” (DGUV) studies, this risk is limited if protective clothing is worn correctly. However, minor carelessness can lead to problematic exposures when firefighters are on duty for decades.

This increases the risk of carcinoma over the years. According to “Deutsche Gesetzliche Unfallversicherung” (DGUV) studies, this risk is limited if protective clothing is worn correctly. However, minor carelessness can lead to problematic exposures when firefighters are on duty for decades.

To better protect firefighters from these risks, the Fraunhofer Institute for Material and Beam Technology IWS in Dresden, together with partners from industry, has laid the groundwork for developing novel anti-PAK protective suits. The German Federal Ministry of Education and Research (BMBF) is funding the project with 1.24 million euros until December 2023 as part of the “Research for Civil Security” program.
 
The innovative protection concept of the new suits includes high-materials and intelligent monitoring: Modern nonwovens, as a central component of the protective suits, effectively prevent skin contact with the pollutants. Ultraviolet sensors are also integrated into the fabrics to determine when the textile protective shield is saturated with PAH and needs to be replaced. This provides double safety for rescue personnel. The new protective clothing has already passed the first tests in fire containers.

PAK-Accumulation over a Lifetime of Work Increases Cancer Risk
“On a single job, it may only be a few micrograms of PAH that get onto the skin through openings in the protective suit,” explains Felix Spranger, Group Manager Gas and Particle Filtration at Fraunhofer IWS. “The treacherous aspect of PAH is that they can continue to accumulate in the firefighters' bodies over an entire working life. Studies from Germany and the U.S. have shown increased incidences of cancer in this occupational group. Therefore, it was important to find solutions incorporating new technological approaches such as smart textiles.” For this purpose, Fraunhofer IWS joined forces with four other partners in 2020 to form the project “3D-Funktionsvliesstoffe mit integrierter Gassensorik für die Schutzbekleidung von Einsatzkräften” (3D-PAKtex, Engl: “3D functional nonwovens with integrated gas sensor technology for the protective clothing of emergency personnel”). To protect firefighters from the harmful PAH in flue gases and soot swirls in burning houses in the future, the collaborative partners pursued a two-pronged concept: on the one hand, the focus was on the development of fleece-based new filters, and on the other hand, on a sensor concept to monitor their functionality.
 
Activated Carbon Fleeces Filter Ring Molecules from Flue Gas
Fraunhofer IWS first identified suitable porous activated carbons that bind PAH particularly well. Project partner Norafin fixed these adsorbents with special binders in nonwovens optimized for fire applications. Norafin's partner S-GARD integrated the new additional nonwovens into a demonstration suit. The manufacturer added small closure pockets at sleeve openings, waistbands, and other points, which can accommodate the new additional filters using press studs at those points where, in the worst case, smoke gases could still enter the suit despite all insulation. If smoke gas flows past these spots, the fleece binds the toxins.

In addition, project partner JLM Innovation equipped the new filter fleeces with specifically engineered monitoring sensors based on fluorescence spectroscopy. These mini-spectrometers emit ultraviolet light of a precisely defined wavelength. When these UV rays hit PAH, the ring molecules first absorb their energy and then send back other UV rays at a slightly different wavelength. The sensors measure the returned light: The more intense, the higher the PAH concentration in the fleece. An electronic control unit in the firefighter's breast pocket evaluates this data and sends it to a smartphone via Bluetooth. The development and implementation of the repective software was accomplished by ATS Elektronik. It enables the rescuers to see in real-time how their PAH filters are filling up and when they need to be replaced.

In laboratory tests, the new nonwoven activated carbon filters have significantly reduced the flue gas PAH load. This was followed by practical simulations in fire containers: Experienced testers donned the suit prototypes, and set fire to mattresses, then rubber tires and other test objects in a shielded container to try out the new protective clothing in different fire scenarios.

“We will thoroughly evaluate these findings and continue to monitor the market to make a well-founded decision on possible series production,” announced Jonas Kuschnir of S-GARD. The new protective approach against PAHs entails certain additional costs, but the project’s results were promising.
 
High Market Potential for Intelligent Textiles Expected
Whatever the outcome of this decision, “3D-PAKtex” has, in any case, led to a considerable gain in expertise for the collaborative partners. The topic will also continue to occupy Fraunhofer IWS. Felix Spranger: “We still see some approaches, for example, to further improve the new protection technology's sensors and interfaces. From feedback, we know that industry partners still perceive great potential in such smart textiles, even beyond protective firefighting clothing.”

This is also consistent with the findings of international observers. For example, analysts at the British market research company IDTechEx expect the market for electronically enhanced or “smart” textiles to grow to the equivalent of around 713 million euros by 2033. Annual growth rates averaging 3.8 percent are expected.

Closing the loop on PET recycling

Ecole Polytechnique Fédérale de Lausanne (EPFL) spin-off DePoly has developed a method for recycling polyethylene terephthalate (PET) at ambient temperature, even when it’s dirty or mixed with other plastics. The firm confirmed the feasibility of its method with a pilot capable of processing 50 metric tons per year. Having recently raised CHF 12.3 million, DePoly is now building a pilot plant with 10 times that capacity.

The firm confirmed the feasibility of its method with a pilot capable of processing 50 metric tons per year. Having recently raised CHF 12.3 million, DePoly is now building a pilot plant with 10 times that capacity.

PET is a ubiquitous plastic used in everything from clothing and shoes to bottles and packaging. Because it’s recyclable, the material has earned solid green credentials. Switzerland produces 45,000 metric tons of PET bottles a year. Yet according to Swissrecycling, some 20% of these bottles aren’t recycled because they’re dirty or mixed with other plastics, so they end up being incinerated. However, the global PET recycling rate is less than 50%, according to a study, conducted for the environmental NGO Zero Waste Europe, so Switzerland is still a strong performer on this front.

In a bid to reduce the carbon footprint associated with PET, DePoly has developed a method for processing it at ambient temperature, even when it’s soiled or tightly interwoven with other fibers. The firm’s demonstrator has a capacity of 50 metric tons per year, and it now plans to use the CHF 12.3 million it raised a few days ago to build a pilot plant. This larger plant – scheduled to open in 2024 and capable of processing 500 metric tons a year – should prove that DePoly’s method is feasible at scale.
 
No need for sorting  
Samantha Anderson, originally from Canada and now DePoly’s CEO, moved to Switzerland in 2015 to begin her PhD at EPFL. When she first unveiled her PET recycling process, which she developed at EPFL’s Laboratory of Molecular Simulation (LMSO) in Sion, it seemed remarkably simple: plastics of all types and colors are mechanically ground then mixed with various chemical compounds – the exact recipe for which is a closely guarded secret. A few hours later, any non-PET plastics remain intact and can be separated out for further processing. The PET, meanwhile, is broken down into terephthalic acid (a powder) and ethylene glycol (a liquid), which can be used to make new material. The method slots seamlessly into existing recycling processes and could be adapted to other kinds of plastics. “Since there’s no heating involved, our method preserves the integrity of other materials like cotton, which is often mixed with PET in clothing and other items” says Anderson.

After graduating in 2019, Anderson decided she wanted to use her expertise to do “something useful for society.” Together with DePoly’s other founders – Bardiya Valizadeh and Christopher Ireland – she spent months testing different formulas for her process. The breakthrough moment came late one Friday when, for the first time, she saw the PET start to decompose before her eyes. By the time she returned to the lab on Monday morning, it had completely broken down. All that remained was for the team to refine the formula and adjust the dosages, hoping that their method would work for larger volumes of PET. Chemical processes can have a major drawback: the pollution they generate often outweighs any gains. “The substances we use are available over the counter, and they aren’t single-use,” says Anderson.

The DePoly team will now start building its first large-scale pilot plant in Valais. The facility will handle dirty and unsorted PET that can’t be recycled via the usual channels. The firm seems to be turning heads on the domestic startup scene: it won the prestigious >>venture>> Grand Prize in 2019 for its technology, and it’s been listed as one of the top 100 Swiss startups for the past three years in a row. But Anderson already has her sights set on the international market. Wouldn’t it be better to eliminate the issue at source by phasing out plastics from our lives? “I’m the first to admit that’s a better option,” she says. “But that’s still a long way off. In the meantime, we’re incinerating tons of PET every day just because it’s slightly soiled or hasn’t been properly sorted.”

Textile dyes were derived from nature before synthetic dyes, discovered by WH Perkin in 1856, revolutionised the textile industry. Today, 90% of our clothing is synthetically dyed, but the toxic effects and ecological impact are extremely harmful to humans and the environment. Over the years, a significant amount of effort has gone into phasing out harmful chemistry and there are consistent efforts to develop non-hazardous chemistry. Today, many alternative dyes from natural sources such as plants, microorganisms, algae and recycled materials are available, however the lack of clarity on their performance and scale makes it difficult for the industry to switch to these sustainable options.

Over the course of a year, 15 selected dyestuff innovations will participate in lab and pilot trials. Innovators will go through extensive compliance and toxicity testing to ensure they are safe for commercial use. Testing and validating the performance of these innovative dyes and pigments on various textile substrates will be supported by the supply chain partners Paradise Textiles and RDD Textiles, University and labs partners NimkarTek, Institute of Chemical Technology and UNICAMP. Furthermore, participating Fashion for Good partners, textile experts and ZDHC will support this project with their expertise and encourage next steps for industry implementation.

After the completion of the project, Fashion for Good will continue developing the library with additional innovators, materials, fabric constructions, testing methods and innovative colouration machineries to enable innovation implementation in the fashion industry.

Smart Home: Textile-based solution for seamless integration of IoT devices

A growing number of people are equipping their homes with smart, networked devices. However, the required connections are not always located where they are needed. The solution: smart textile surfaces that make walls and floors in the living area usable for cable-based power supply and communication. The innovative technology was developed by a consortium led by the German Research Center for Artificial Intelligence (DFKI) in the ConText project funded by the German Federal Ministry of Education and Research (BMBF).

The innovative technology was developed by a consortium led by the German Research Center for Artificial Intelligence (DFKI) in the ConText project funded by the German Federal Ministry of Education and Research (BMBF).

There are many ways to make living environments intelligent. Thanks to the so-called Internet of Things (IoT), living objects can be connected with each other in such a way that they make our everyday lives easier in many ways. However, private households generally lack comprehensive low-voltage and communication connections to install IoT components such as temperature sensors, microphones, or light signals where they are needed. As a result, the devices usually operate on batteries and wireless technologies, which makes them susceptible to interference and failures.

Textile-based power supply, communication, and interaction
But how can the desire for creativity and flexibility in the use of smart home systems be met while at the same time dispensing with unfavorable energy supply and data communication? This was the question addressed by a consortium of industry and research partners in the ConText ("Connecting Textiles") project, which has now been completed. Inspired by the possibilities of smart textile materials, such as those already used in the manufacture of smart clothing, the partners investigated the potential of electronic textiles for cable-based low-voltage power supply and communication in indoor spaces. In an exploratory and use-oriented process, they developed an infrastructure that takes advantage of wired connections while integrating invisibly into textile surfaces. The so-called Connecting Textiles not only enable the flexible attachment of actuators and sensors in living areas by means of freely positionable patches, but also power supply and communication with smart home systems. In addition, the developed infrastructure provides haptic interaction modalities for intuitive control of IoT devices.

Demonstrators provide infrastructure via textile wallpaper
Demonstrators produced in the project implement the Connecting Textiles using a wallpaper as an example. The wallpaper consists of several layers: a magnetic backing layer that increases the adhesion between the patches and the wallpaper, a functional layer with woven-in conductor tracks that distribute the current vertically through the wallpaper, and a decorative top layer. To create the conductive traces, the partners investigated various woven and non-woven materials, such as those used today for standard wallpaper, as well as different processing techniques, including screen printing and weaving. Woven samples proved to be the most suitable for the functional layer due to their comparatively high conductivity. The electrical contacting of a wallpaper strip is made via the baseboard, which also connects adjacent wallpaper strips to enable large-area applications. The strip also contains the necessary electronics as well as functions that monitor the current flow to detect possible damage to the wallpaper or incorrectly applied strips.

User-oriented development of intuitive interaction elements
Functional patches serve as the central interaction elements of the Connecting Textiles, which can be flexibly attached to the wallpaper either with the help of magnets or by means of microneedles mounted on the back. The patches can either contain an IoT functionality, e.g., a sensor, or connect one or more IoT devices to integrate them into the smart home system. Control and configuration of the devices can also be done directly on the wallpaper via an additional interaction patch fabricated by screen printing on textile. Pattern recognition software captures the basic patterns of gesture interactions and allows control gestures and interaction sequences to be defined by the user. The interaction concept was developed and evaluated in the project in a participative way with the direct involvement of users.

Dr. Serge Autexier, ConText project manager at DFKI's Cyber-Physical Systems research department: "Thanks to the commitment and very good collaboration of the project partners, we have succeeded in demonstrating the feasibility of Connecting Textiles as a flexible, adaptable and easily configurable interaction medium that can be seamlessly integrated into Smart Homes. This not only opens up new possibilities for the confection of functional textile surfaces, but also for the development of novel IoT applications and the creative design of personalized human-environment interaction beyond the application context of home environments.”

One of the demonstrators developed in the project is integrated into the infrastructure of the Bremen Ambient Assisted Living Lab (BAALL) of DFKI as part of the Smart Home environment.

ConText was funded by the German Federal Ministry of Education and Research (BMBF) from July 1, 2019 to Dec. 31, 2022.

Clothing embedded with 1,200 tiny solar panels

  • The future of wearable tech

Textiles embedded with more than a thousand miniature solar cells - which are capable of charging a smart watch or mobile phone - have been developed by researchers at Nottingham Trent University.

Research overseen by Dr Theodore Hughes-Riley, associate professor of Electronic Textiles at the Nottingham School of Art & Design, has led to the development of a woven textile embedded with 1,200 photovoltaic cells.

The e-textile is an advanced prototype which could be incorporated into a piece of clothing such as a jacket, or used as part of an accessory such as a backpack. The cells combined together are capable of harnessing 400 milliwatts (mWatts) of electrical energy from the sun – enough to charge a basic mobile phone or smartwatch.

  • The future of wearable tech

Textiles embedded with more than a thousand miniature solar cells - which are capable of charging a smart watch or mobile phone - have been developed by researchers at Nottingham Trent University.

Research overseen by Dr Theodore Hughes-Riley, associate professor of Electronic Textiles at the Nottingham School of Art & Design, has led to the development of a woven textile embedded with 1,200 photovoltaic cells.

The e-textile is an advanced prototype which could be incorporated into a piece of clothing such as a jacket, or used as part of an accessory such as a backpack. The cells combined together are capable of harnessing 400 milliwatts (mWatts) of electrical energy from the sun – enough to charge a basic mobile phone or smartwatch.

Fitted with strong but very flexible wiring, it is designed to be exposed to the same forces as everyday clothing and can be washed in a machine at 40°C with other laundry.

The solar cells - which measure only five millimetres in length and 1.5 millimetres in width - are embedded in a waterproof polymer resin and cannot be felt by the wearer.

“This prototype gives an exciting glimpse of the future potential for e-textiles,” said Dr Hughes-Riley, of the university’s Advanced Textiles Research Group (ATRG).

“Until now very few people would have considered that their clothing or textiles products could be used for generating electricity," explains Hughes-Riley. “And the material which we have developed, for all intents and purposes, appears and behaves the same as any ordinary textile, as it can be scrunched up and washed in a machine. But hidden beneath the surface is a network of more than a thousand tiny photovoltaic cells which can harness the sun’s energy to charge personal devices. Electronic textiles really have the potential to change people’s relationship with technology, as this prototype shows how we could do away with charging many devices at the wall. This is an exciting development which builds on previous technologies we have made and illustrates how it can be scaled up to generate more power.”

The material - which measures 51cm by 27cm - is breathable and chemically stable as all the solar cells are made from silicon. Tests showed that the material generated a power output of 335.3 mWatts in 0.86 sunlight. Under 1.0 sun it would generate up to 394 mWatts.

The project team included Dr Neranga Abeywickrama, who worked as a postdoctoral research fellow in Energy Harvesting and Management in Textiles, and PhD candidate Matholo Kgatuke, research associate in the Weaving of Electronic Textiles.

Ms Kgatuke, of the Nottingham School of Art & Design, said: “This project shows how e-textiles can be at the forefront of sustainability and that they have the potential to reshape our existing conceptions of technology. We have combined long-established weaving techniques with modern technology to create future products which may change people’s perceptions of clothing and electronics.”

The Future of Natural Textile Dyes

  • Lab-grown Pigments and Food By-Products

As the environmental impact of the fashion and textile industries becomes clearer, the demand and need for sustainable alternatives is growing. One international research group aims to replace toxic synthetic dyes with natural alternatives, ranging from plants to microbes to food waste.
 
Walk into any clothing store and you'll find a rainbow of fluorescent shirts, pastel sweaters and blue jeans that rotate in and out of style each season. The colours of each garment are pristine, eye-catching and identical, but there are consequences hidden in those racks of colourful clothes.

Walk into any clothing store and you'll find a rainbow of fluorescent shirts, pastel sweaters and blue jeans that rotate in and out of style each season. The colours of each garment are pristine, eye-catching and identical, but there are consequences hidden in those racks of colourful clothes.

Our planet and the factory workers producing our clothes are paying a steep price: toxic chemicals used in the synthetic dyeing process pollute waterways and soil.
Introduced in the 1860s, synthetic dyes and pigments have become commonplace in the textile industry. These dyes are part of the reason why clothes of every colour imaginable are so readily available: they offer quick and easy alternatives to the natural sources of colour that used to be the only option.

While this synthetic process has become normalised, using natural pigments to dye textiles has been part of human history for thousands of years.
BioColour suggests it's time to revisit and reimagine this long history.

Associate Professor in Design at Aalto University and member of the BioColour research group Kirsi Niinimäki explains, ‘We’re looking back in history to see how we can bring the information we had before synthetic chemicals existed to the current day, but also how we can apply it in a more modern way by working with the [textile] industry.’

BioColour is an international research consortium of designers, material scientists, biologists, mathematicians and engineers. These researchers from Finnish, American and Brazilian universities and research institutes work together to find non-toxic and biodegradable natural alternatives to synthetic dyes and pigments.
 
Natural dyes at an industrial scale
BioColour’s research isn't just about identifying and testing natural colour sources, it's also about working with the textile industry and consumers to bring widespread change to the new normal of synthetic colours.

One such example comes from Finnish design house Marimekko. Using dyer’s woad, a plant native to Finland, the project tested this alternative to synthetic indigo, a dye that's created using toxic chemicals like formaldehyde.

This collaboration revealed an additional perk of natural dyes: as a Finnish design house, by using a plant cultivated in Finland, Marimekko could tell a local story with dyer’s woad that wasn’t possible with synthetic indigo.

Such collaborations are an opportunity to challenge and learn from each other, says Niinimäki. While BioColour challenges industry partners to work with different methods and recipes that draw on historical practices, industry partners put dye recipes to the test outside of precise laboratory conditions.

‘In a laboratory, it’s possible [adjust] processes, but when we go to the industry, it’s not possible to precisely modify the recipes,’ says Niinimäki, ‘we have to accept the industrial processes and what comes out of them.’

The textile industry isn't the only source of collaboration: Food and agricultural industries create massive amounts of biowaste that spell untapped potential of natural dyes. By-products such as onion skins and willow bark from these industries can be used to dye clothing, creating new side streams and reducing waste.

Though the details are still secret, Niinimäki also described an ongoing collaboration with a food company that aims to investigate how much pigment can be extracted from food waste material. They will also test the durability of said colours.

Changing attitudes towards colour
Ensuring consumers are willing to purchase naturally dyed textiles is vital in the quest to replace synthetic dyes. Yet, consumers still find this concept to be a strange one, according to Niinimäki.

Synthetic dyes are appealing because they provide long-lasting and identical colours between each garment. As Niinimäki points out, however, that ‘sameness’ is one of fast fashion’s problems.

‘Blue is a trendy colour, but why does everything have to be the same blue? Even in mass production, why can’t we accept that there might be different kinds of blue? Why does everything have to be the same?’

Natural dyes, which are not as stable, may look different from garment to garment and even fade over time.
These fading colours don't need to be seen as a negative, however.

Niinimäki believes fading colours open the door to an attractive new type of design: garments could be designed to reveal new patterns as certain colours fade over time.

While BioColour’s consumer studies aim to identify and change current attitudes to colours and textiles, other researchers in the group are investigating the durability and longevity of natural dyes. Fading colours may offer interesting design potential, but they aren't the only option.

Drawing on history to invent the future
Natural sources of colour aren't limited to plants and mushrooms—the world of microbes offers huge potential for the future of dyes and pigments.

Bacteria can be a source of non-toxic biodegradable pigment and a method of helping dyes to stick to textile fibres. Using bacteria in the natural dyeing process harkens back to the slower pace of fashion, as it can take weeks of growing and feeding the bacteria.

This use of bacteria in the dyeing process has inspired BioColour collaborators from the VTT Technical Research Centre to investigate lab-grown colourants. Their research explores how the DNA of microbes can be modified to produce a variety of different pigments that could be scaled to wider textile production.
 
Lab-grown colourants are a particularly promising future because, as Niinimäki explains, there is limited land to cultivate plants for dyes. Climate change is and will continue to change our environment and cause food and water insecurity. This means resources will need to be diverted to food cultivation.

These pigment-producing microbes expand the possibilities of non-toxic, biodegradable dyes while saving land and resources in the process.
While it may be drawn from history, the research behind natural dyes is anything but old news.

Study: More investment needed in fiber-to-fiber recycling infrastructure

Fiber-to-fiber textile recycling legislation and policies are steadily increasing and are one of the key strategic components to support the transition to a circular economy in the fashion industry.

At the same time, the demand for an infrastructure for collecting, sorting and recycling end-of-life textiles is likely to increase across the EU. Adapting this infrastructure will require significant investment. In order to plan these holistically in the future, it is necessary to understand both the characteristics of the used textiles available on the European market and the business case for monetization through recycling.

Fiber-to-fiber textile recycling legislation and policies are steadily increasing and are one of the key strategic components to support the transition to a circular economy in the fashion industry.

At the same time, the demand for an infrastructure for collecting, sorting and recycling end-of-life textiles is likely to increase across the EU. Adapting this infrastructure will require significant investment. In order to plan these holistically in the future, it is necessary to understand both the characteristics of the used textiles available on the European market and the business case for monetization through recycling.

Fashion for Good, the global initiative for sustainable fashion presented on September 27, 2022 the final report on the project "Sorting for Circularity Europe", which was launched in May last year with the aim of filling knowledge gaps and studying materials in depth. The project aims to analyze the types of waste generated, the quantities available as raw material for recycling, and the potential for channeling textile waste as raw material for innovative solutions. The report provides preliminary meaningful information on the basis of which informed decisions can be made for further investments, policy developments and next steps towards a circular economy.

Overall, the Sorting for Circularity Europe study concludes that in six European countries - Belgium, Germany, the Netherlands, Poland, Spain and the United Kingdom - 494,000 tons, or 74%, of low-value post-consumer textiles are readily available and suitable for closing the loop in the apparel and textile sector each year.

This presents promising opportunities for value recovery through mechanical and chemical recycling, diverting textiles from less circular uses such as downcycling to nonwovens, insulation or filling materials, the wipes industry and incineration. This equates to a potential value gain of EUR 74 million per year if sorted textiles are reintroduced into the textile value chain.

By using innovative near-infrared (NIR) technology to determine the composition of garments - a task traditionally performed manually - the project analyzed 21 tons of used clothing. The on-site surveys took place over two periods, fall/winter 2021 and spring/summer 2022, to account for seasonal changes in garments entering sorting facilities. The project focuses on textiles that cannot be reused in their original form and are therefore considered "non-reusable" and textiles that can only be resold at low prices = "low-value reusable textiles".

Cotton is the predominant fiber with 42%, although a relevant share of this category could be elastane. Cotton is followed by a high proportion of material blends (32%), of which almost half are polycottons (12%). Based on three characteristics: material composition, presence of interfering factors such as zippers and buttons, and color, 21% of the materials studied were considered suitable for mechanical recycling, while 53% appeared suitable for chemical recycling. However, the removal of interfering materials for chemical recycling must be technically and financially feasible, otherwise only about one-fifth of the total potential feedstock would be eligible for chemical fiber-to-fiber recycling.

The amount of low-value textiles collected is expected to increase, partly due to increasing consumption and disposal, but also due to new legislation, such as the Waste Framework Directive, which requires separate collection of textiles across Europe by 2025. However, the current and future potential of these textiles for the circular economy is difficult to exploit; raw material prices for current uses (e.g. wipes) are sometimes more economical than fiber-to-fiber recycling prices. This could change if current recycling technologies are scaled up and further investments are made to integrate operations such as automatic sorting and the removal of impurities in the sorting process.

Overall, a solid business case for low-value textile sorting is needed to maintain and increase sorting capacity in Europe. This also highlights the need for increased investment in infrastructure that can sort and prepare textiles for reuse and recycling. To support the maintenance and further expansion of this sorting capacity in Europe, policy and future legislation will play a key role in ensuring the environmental, social and financial sustainability of these stages of the apparel and textile value chain.

Based on the project results, the authors make the following recommendations:

Use of the sorters' handbook and the report "Sorting for Circularity Europe" as a guide to conduct further trials and to continue building knowledge on fiber composition, sorting and recycling processes. This could be further supported by local authorities, industry and civil society dealing with textile or household waste streams.
  2. Open access to trials and data that can support and guide investment in the necessary infrastructure.
  3. Update and use the recycler database to increase knowledge of mechanical and chemical recycling destinations.
  4. Joining digital platforms such as Reverse Resources and Refashion Recycle to tap into and connect the supply of and demand for post-consumer textiles.

For brands and manufacturer
74% of low-value used textiles could be used as raw material for recycling. While this is a significant proportion, there still remains 26% that cannot be recycled due to their composition, the presence of multiple layers and/or non-removable contaminants.

  1. Priority for the design of an appropriate life cycle.
    For products designed for longevity, there should be a strong focus on durability and long-term performance. Ultimately, recycling textiles in line with the waste hierarchy should be the last resort and not the goal in itself.
  2. Further commitment to adopt circular design practices that prioritize mono-materials, reduce disruptive factors as much as possible, and include recycled fibers in the product portfolio, as required by the Ecodesign Regulation for sustainable products in the European Union.

For policy makers
Sorting companies in European countries run the risk of not being able to continue their business as usual if the share of these low-quality textiles in the collected volumes continues to increase. In addition, current sorting and logistics costs may pose a financial challenge for chemical recyclers to acquire these textiles in large volumes.

  1. Consider the introduction of Extended Producer Responsibility (EPR) schemes with sufficient financial support to alleviate pressure on the business base of sorting companies to manage future volumes of collected textiles.
  2. Introduce an environmental subsidy to lower the price of recycled fiber as the industry expands. This subsidy could alleviate cost pressures on recyclers, potentially facilitating the purchase of non-renewable raw materials at prices competitive with other commercial destinations such as wipes.
  3. Introduce legislation at different stages of the clothing and textile life cycle to influence the potential for recycling the non-depletable portion of PCT (post-consumer textiles), such as the introduction of mandatory eco-design requirements that include a fiber-to-fiber recyclability perspective for products.
  4. Assessment of any unintended consequences that might result from setting mandatory targets for preparation for reuse and recycling (to be considered by the European Commission by 2024).
  5. Align rules on sorting criteria for reuse and recycling across the EU to help harmonize standards and requirements of the sorting industry for preparing textiles for reuse and recycling.
  6. Examining how digital labeling and product passports can improve the traceability of materials in the textile value chain at the end of their useful life in the long term.

For consumers
Purchasing and disposal decisions also have an impact on the end of the use of textiles. Priority should be given to purchasing products made of a single material or blends that are limited to two components, as well as aesthetic decorations and accessories. Clothing and home textiles must be disposed of according to regulations. To extend the life of products, repairing, reselling and exchanging are options.

Dissolvable stitches that improve clothing recycling

Resortecs has developed an innovative solution that helps solve a widespread fashion industry challenge: how to recycle garments more effectively.
 
The challenge relates to stitched clothes such as jeans or jackets, that need to be taken apart before their constituent materials can be recycled. The existing disassembly process is time-consuming and costly, as the garment and its components are held together by a synthetic high-strength thread, which in most cases is polyester. Before recycling, the garment has to be separated and the thread removed, otherwise the quality of the recycled product will be compromised.

Resortecs has developed an innovative solution that helps solve a widespread fashion industry challenge: how to recycle garments more effectively.
 
The challenge relates to stitched clothes such as jeans or jackets, that need to be taken apart before their constituent materials can be recycled. The existing disassembly process is time-consuming and costly, as the garment and its components are held together by a synthetic high-strength thread, which in most cases is polyester. Before recycling, the garment has to be separated and the thread removed, otherwise the quality of the recycled product will be compromised.

Resortecs has designed a new type of thread that makes the disassembly process easier. Their threads are available for different melting-points (150° C, 170° C and 200° C) and dissolved using a commercial oven. The choice of thread depends on the type of garment that is being taken apart. The Resortecs® solution allows up to 500kg of garments (=>1000 pairs of jeans) to be dismantled at the same time.

Why it’s an example of the circular economy
Currently less than 1% of all garments are recycled to a high quality. The rest are downcycled, incinerated or landfilled, translating into a loss of USD 100 billion worth of material annually.

The production of new materials to replace those that are landfilled or incinerated, accrues significant environmental and social impacts, including massive freshwater consumption, land degradation and greenhouse gas emissions. For example, 2.4% of the world’s arable land is cultivated with cotton, but growing cotton accounts for 24% of the world’s annual demand for insecticides.

There are many factors that contribute to the low rate of garment recycling. One key contributor is the high cost associated with disassembly, which due to complicated and durable designs is a predominantly manual process. Furthemore, according to industry research including data from garment recycling companies in Pakistan, between 30 - 52% of denim is lost during disassembly.

In the Resortecs® process only 10% maximum of textile material is lost, and the integrity of the textile is not damaged, meaning that new garments can use a higher percentage of recycled material. Furthermore the process makes the garment dismantling process much easier and five times faster. This improves the effectiveness and economic viability of recycling, particularly in countries where labour costs are high.      

Business and environmental benefits
Resortec’s enabling technologies reduce the use of virgin materials which can save costs and reduce exposure to unpredictability in resource prices and changing regulations. In the past years, consumer trends have shifted towards more environmentally conscious choices, including the use of recycled materials. And because 50% of carbon emissions and 75% of water use occurs in the production and material processing stage, this model also hugely reduces negative environmental impacts.

The journey continues
There are no silver bullets in the circular economy and often a product might be described as ‘circularish’, to reflect the continuing journey of improvement.

For Resortec’s technology to realise its full potential, other actors in the fashion system need to play their part. For example, reverse supply chains (sorters and recyclers) must adapt and optimise their operations to suit these new solutions. Designers and brands also need to understand the limitations and push the limits of circular design, for example by designing/specifying reusable buttons and zips. Policy makers need to send the right signal to the market, such as France’s forthcoming anti-waste law which bans disposal of unsold clothes into landfills.
          
As well as system changes, there are also potential improvements in the technology. Currently Resortecs uses a plastic based thread, which when melted should ideally be recovered and re-spun rather than discarded. The thread could also be sourced from recycled or regenerative production methods.

There is clearly already a growing appetite for Resortec’s technology which is already being piloted by 25 international fashion brands with at least one Resortec-enabled product already on the market. As the fashion industry continues to evolve, simple but powerful innovations such as this can help unlock the potential of a circular economy for fashion.

Second Skins: e-Textiles redefined

As part of the European STARTs project Re-FREAM, designers, technologists and scientists researched together on future as well as sustainable technologies for the textile industry. In the research focus area of e-Textiles, the fashion tech expert Malou Beemer from the Netherlands worked with an international team consisting of Profactor, EMPA, Wear It Berlin and Fraunhofer Institute for Reliability and Microintegration IZM on adaptive garments that can adapt to the practical and social needs of users.

As part of the European STARTs project Re-FREAM, designers, technologists and scientists researched together on future as well as sustainable technologies for the textile industry. In the research focus area of e-Textiles, the fashion tech expert Malou Beemer from the Netherlands worked with an international team consisting of Profactor, EMPA, Wear It Berlin and Fraunhofer Institute for Reliability and Microintegration IZM on adaptive garments that can adapt to the practical and social needs of users.

Malou Beemer approaches garment sustainability though her deep understanding of the social functionality of garments. Her research reflects on how design can change the way we want, wear, and discard fashion. Could smart garments be equipped to improve and maintain their desirability? Her modular Second Skins garment system combines adaptive parts which create a personal light symphony. Its composition responds to the aesthetic need for novelty, for interaction, and for standing out.

Beemer started with deconstructing the idea of the garment itself. First, she explains, “we stepped away from the idea that a garment always has two legs or two sleeves”. Instead, the team decided to visualize it as components. The next step was researching the activation of responsive and reactive textiles elements, which could be modulated to create novelty.

With a main focus on evening and party wear, a category showing high single use behavior, the choice fell on color changes based on LED patterns. With her Re-FREAM partners, she conceived a garment consisting of a base layer integrating LED lights with IZM Fraunhofer, a diffuse layer which alters the light with Profactor, and a top layer which gives a final shape to the garment as well as allowing for further updates. Wearers can upload LED color patterns, then modulate them with a tap sensor. Due to the construction and modular bonding technique the garment can be repaired when needed or even completely disassembled and the end of life.

Beemer uses the customization of garment colors, patterns, and structures to enhance garment lifespans. She defines sustainability through longevity: the goal is garments that update, perhaps for decades. Her wearable tech designs also aim to enhance social interactions with others. A particularly innovative aspect of her concept is her aim for new levels of garment agency. She envisions clothing which cares for us, according to our social and aesthetic needs. Instead of passive and polluting garments, Beemer envisions fashion as a second skin, with different layers which can shift properties. Allowing for such inbuilt versatility gives garments an active role in their survival, as well as in ours.

Together with the Fraunhofer team, Beemer created two undergarments integrating PCBs (printed circuit boards) and LEDs: one that centered more around the neck, and one more centered around the ribs, below the bust. The Second Skins project uses hardware modules developed by IZM. IZM developed an Arduino-based modular hardware platform that enables easier, more flexible and more reliable integration of e-textile prototypes and small series into textiles. Modules already available include various sensors (temperature, proximity, pulse, IMU) as well as actuators, RGB LEDs, ADC, µC, Bluetooth and more. In addition to the conventional sewing of the modules using electrically conductive yarn, all modules also offer the possibility of integrating them mechanically and electrically in a single step using the proprietary e-Textile Bond technology developed at IZM.

Here, for example, Smart IMU modules record the wearer's body language and movement data, and proximity sensors are also integrated. The sensor data obtained can be used to control individual lighting effects of the RGB LED display, through which the wearer communicates non-verbally with her surroundings. All modules can be freely placed on the garment during the design process. For power supply and communication with the process unit, a textile 4-wire IIC bus conductor made of a thermoplastic insulated hybrid conductor of stranded material and reinforcing textile fibers is embroidered onto the undergarment, thus connecting the modules. The electrical connection between the module and the textile bus is then made using the e-Textile bonding technology described above, which provides reliable but also repairable contacting without the need for additional additives such as pastes, fluxes or the like. Due to the remeltability of the thermoplastic adhesive, the module can also be thermally removed from the carrier again. The inner layer between the upper and lower garment contains thin textile layers that allow masking of the lighting effects by means of 3-D printing or lamination, thus allowing the user to customize the lighting design.

After a Corona-related break of three years, the leading trade fairs Techtextil and Texprocess are once again presenting the renowned Innovation Awards. The award-winning new developments from areas such as New Products, Sustainability and Automation demonstrate: Textile innovations and technologies provide impulses for many branches of the industry and promise market and sales success far beyond their own sector. 13 winners from seven categories will be honored at a public awards ceremony at Techtextil and Texprocess on 21 June, 2022.
 
As is the case for many other industries, times are challenging for the textile industry: the consequences of Corona, the Ukraine war, strained supply chains, sustainability issues, rising energy prices and recruitment problems - the industry is under pressure from many sides. But more than almost any other industry, it is also very adept at meeting these challenges with new ideas, developments and business models. This year's Innovation Awards at the leading trade fairs Techtextil and Texprocess are another example of this. With their new products, materials, solutions and processes, the 13 award winners are demonstrating in an exemplary manner that textile innovations are the ideal way to create market opportunities and boost future business revenues, out of the challenges of the present.

Techtextil Innovation Award and Texprocess Innovation Award
The Techtextil and Texprocess Innovation Awards will be presented on 21 June, 2022 in Hall 9.0. Textile innovations selected by international expert juries will be awarded prizes and presented publicly on the four days of the trade fair in Hall 9.1 (Techtextil) and 9.0 (Texprocess), in some cases for the first time.

World's first: first woven heart valve without postfabrication
In the "New Product" category, the Techtextil Innovation Award goes to the Institute of Textile Machinery and High Performance Material Technology (ITM) at the Technische Universität Dresden. Together with medical product manufacturers and heart surgeons from the Cardiovascular Center Würzburg and the Universitätsklinikum Würzburg, textile researchers from the ITM have succeeded in developing the world's first woven heart valve that does not require a single seam or other joining technique. "Our new development should also help children with heart valve defects in the future by growing with the heart of the young patients - avoiding repeated surgical interventions," says Dr.-Ing. Dilbar Aibibu, research group leader for biotextiles and medical textiles at ITM. Worldwide, cardiovascular diseases are among the most common causes of death; several million people die from them every year. When patients receive heart valve replacements, artificial mechanical or biobased solutions are usually used. If ITM has its way, the woven valve, which won the Techtextil Innovation Award, should become a beneficial alternative in the future.

Reuse of waste from a natural source
In the "New Material" category, RBX Créations (France) receives the Innovation Award for a novel cellulose fiber made from hemp waste. The material, named Iroony®, was developed with regard to the following question: Hemp is now grown either to make fiber or to produce hemp oil - but could not the two be combined? RBX Créations has now succeeded in developing a process for extracting cellulose from the waste of oilseed hemp. Spun into textile fibers, it can be used to produce sustainable textiles, packaging and other "green" products. The award is given to RBX Créations for its continuous and successful efforts to convert waste from a renewable source into a valuable cellulose fiber that meets the highest sustainability standards.

Fiber shielding technology for hospitals, electric cars and server farms
The Techtextil Innovation Award in the "New Technology" category goes to Aachen-based FibreCoat GmbH and Deutsche Basalt Faser GmbH from Sangerhausen (Saxony-Anhalt) for the joint development of an aluminum-coated basalt fiber. It combines the strength of basalt with the electrical conductivity of aluminum. According to FibreCoat, electromagnetic shielding as wallpaper in buildings in hospitals or server farms, among other places, should be up to 20 times cheaper than with conventional aluminum foil thanks to the new development. Another attractive and particularly fast-growing market is shielding solutions for electric cars. Robert Brüll, CEO of FibreCoat: "For a young company like ours, winning the Techtextil Innovation Award is an important milestone. We are honored to receive this prestigious award from the independent jury of experts. In particular, the confidence of our customers and visibility gained as a result are crucial for a start-up like FibreCoat on the road to market success."
 
More sustainable hygiene products such as diapers
Kelheim Fibres GmbH from Kelheim in Bavaria and the Saxon Textile Research Institute (STFI) in Chemnitz receive the Techtextil Innovation Award in the "New Concept" category for the development of novel, thermally bonded nonwovens based on cellulose for the production of reusable products with high absorbency. Consumers should no longer have to choose between high-performance or environmentally friendly products. Nature and performance of hygiene products go hand in hand thanks to the innovation of Kelheim, STFI and the Berlin-based start-up SUMO. Dr. Marina Crnoja-Cosic, Director New Business Development at Kelheim Fibres: "It is a great honor and pleasure for us to receive the Techtextil Innovation Award together with our partners. We see the award not only as a distinction for the project presented, but also as recognition of our innovation strategy. After all, in dialogue with partners we can react more quickly to current trends, develop in a more targeted manner and accelerate the commercialization of innovative solutions."

Waste from the automotive industry as a resource
Another Techtextil Innovation Award in the category "New Approaches on Sustainability & Circular Economy" honors a process that uses natural leather waste from the automotive industry to produce innovative textile coatings. It was developed by CITEVE, the Technology Center for Textile and Clothing in Portugal, and partners ERT Têxtil Portugal, CeNTI and CTIC (all Portugal). After CITEVE researchers discovered that cutting operations in the automotive industry generate a large amount of natural leather classified as waste, they sought a solution to reuse it. The expert jury recognizes the development as a successful industrial symbiosis: "Waste from one industrial sector is used here as a resource in another. The work of the CITEVE researchers thus supports an important trend toward a resource-efficient, environmentally friendly and sustainable textile industry."

Compostable textile coating
The Techtextil Innovation Award in the category "New Approaches on Sustainability & Circular Economy" goes to the textile research institute Centexbel (Belgium) for a bio-based and compostable dispersion for textile coatings and printing inks. The new development does not require solvents and brings a completely new type of polymer for coatings and printing inks to the market. According to the expert jury, the innovation is an important step for the textile coating industry towards more products based on renewable resources.

Fashion from pineapple peel
The Italian company Vérabuccia is honored in the "Performance Fashion Award" category for an innovative production process for the fashion and design sector. The patented process is designed to transform fruit waste into fashion highlights. A first material is the so-called "Ananasse". According to Vérabuccia, the special feature of this is that unlike other plant leathers, which tend to imitate real animal leather, it retains the original appearance of a pineapple skin; this emphasizes the origin of the raw material. With the Techtextil Innovation Award, the jury honored the unconventional thinking of the young Italian label, whose originality proves that innovative and appealing fashion can be developed from surprising materials.
 
100 percent compostable binder for nonwovens
In the "New Technology" category, the company OrganoClick (Sweden) receives the Techtextil Innovation Award for the development of a 100 percent bio-based binder for nonwovens applications that is made from waste components and is therefore said to be fully compostable. The innovation is designed to replace plastic-based binders. Because nonwovens are often made from non-degradable plastics, the Swedish company specializes in developing compostable material alternatives from wheat bran, fruit or crab shells, among others. This convinced the jury of the Techtextil Innovation Awards: "OrganoClick receives the award for its efforts to find bio-based raw material alternatives to replace oil-based materials."

Formaldehyde-free & bio-based coating system
The third award in the category "New Approaches on Sustainability & Circular Economy" goes to Deutschen Institute für Textil- und Faserforschung Denkendorf (DITF) from Baden-Württemberg and the company TotalEnergies - Cray Valley (France). Together, they have developed a novel, formaldehyde-free coating system. It is based on non-toxic hydroxymethylfurfural (HMF) derived from biomass waste. These HMF-based dip formulations are capable of replacing formaldehyde-based adhesion promoters on a one-to-one basis. For background: in tires, conveyor belts or V-belts, rubber materials are reinforced by cord. The quality of such cord composite systems with high-strength fibers such as polyester, aramid or polyamide and rubber is determined by the adhesion properties of the fibers to the matrix. In the established manufacturing process, adhesion promoters made of resorcinol-formaldehyde-latex (RFL) are used. However, formaldehyde has been classified by the EU as a proven carcinogen and mutagen since 2014. The jury therefore welcomes the health and environmentally friendly new development. It contributes to a more sustainable textile industry and the reduction of harmful chemicals.
