US Nonprofit organisation the Apparel Impact Institute (AII) has estimated the fashion industry’s emissions for 2024 at just over 1 gigatonne, an increase of 6.3% compared with the year before. According to AII, this increase was mainly driven by an increase in the amount of fibre used to produce apparel, particularly polyester. Tiertwo activity, which is textile processing, has the largest share of the apparel sector’s emissions, with 51% of the total. Raw material production is next, with a 26% share. • The Textile Exchange’s newly published annual report for 2025 shows more than 100,000 sites around the world are certified to its material sustainability standards. The company said its standards collectively grew 12% year on year, more than 30 million hectares of land are certified to its Responsible Wool Standard and a record 423 brands and retailers reported into its Materials Benchmark. However, the fashion industry remains off track to meet the goal of reducing greenhouse gas emissions from fibre and raw material production by 45% by 2030, in line with the Paris Agreement.

SPORTSTEXTILES WHEN SYNTHETICS BET ON RENEWABLE OVER FOSSIL
Occupying a middle ground between natural and petrochemical, synthetic fibres made from renewable resources may hit the right chord with brands looking to lighten their environmental footprint. But these biopolymers also come with their fair share of issues, related to land use, price competitiveness, and the term ‘bio’ itself, which can have many meanings.
When synthetics bet on renewable over fossil
B
iopolymers come in many forms. The cellulose in cotton is a natural biopolymer, whereas that of manmade cellulosic fibres has been modified, or regenerated, to use an industry term. Not entirely natural. Biosynthetic fibres, derived from renewable rather than fossil resources, are yet another category. Their building blocks, or monomers, come from industrial sugars, such as glucose, or from oils, such as castor bean oil. They combine the performance characteristics of synthetics with the draw of a lighter, biogenic carbon footprint. While this sounds like the best of both worlds, biopolymers have largely remained marginal players in the market. The complex chemistry of converting biomass into chemicals makes them more expensive than petrochemical synthetics. They also face competition on the sustainability front, as ‘recycled’ is considered an easier sell than ‘bio’. Although brands claim to be looking to reduce their emissions, biopolymers do not seem to benefit from these (often halfhearted) efforts. In its latest, 2026 materials report, Textile Exchange estimates that the market share of biobased polyester was 0.01% of global production in 2025. Ahead by a slim margin, biopolyamides are said to make up around 0.5% of the total market for nylon. Anticipating that demand will eventually materialise, fibre producers have been investing heavily in technologies and factories to produce plantderived chemicals and ingredients. Korean fibre producer Hyosung has launched production at a brandnew factory in Ho Chi Minh City, Vietnam, with the capacity to produce 50,000 tonnes of biobased butanediol (BioBDO) per year. A $1 billion investment. The site was chosen for its proximity to a Hyosung elastane facility, further lightening the footprint of its regen Bio Elastane. The company says it is prepared to increase capacity to 200,000 tonnes annually if market demand follows. The Lycra Company is also betting that brands will switch to its bioderived elastane and has 04
been actively campaigning for the adoption of its Renewable Lycra fibre. Its launch was made possible by the construction of a 66,000tonne peryear bioBDO factory in Eddyville, Iowa. A $300 million investment by Qore, jointly owned by US group Cargill and Germanybased HELM, it sources corn within a 100mile radius. Describing the company’s strategy, Alistair Williamson, The Lycra Company’s head of sustainability, tells Sportstextiles that “the strongest appeal is that Renewable Lycra fibre helps brands and mills move away from fossilbased resources without asking them to compromise on the performance consumers expect from Lycra fibre. It delivers the same stretch, recovery, comfort, fit and durability, while offering 70% plantbased content derived from annually renewable feedstock”.

Scaling up CovationBio, a DuPont spinoff now owned by Chinese textile group Huafon, was the first to industrialise production of a biopolyester, a polytrimethylene terephthalate (PTT), with 37% renewable content. The launch of Sorona goes back to the early 2000s. Huafon is now investing in a new biobased platform, bioPTMEG, to which it has applied the brand name Xatryx. It recently sold its stake in Primient Covation, which produces bioBDO, to Primient while securing sourcing rights. It has announced it is investing RMB 10 billion (or €1.2 billion) in a 50,000tonneperyear bioPTMEG plant in Qidong, Jiangsu Province, referring to it as its new C4 Platform because the factory will convert C4 chemicals (those with four carbon atoms), including BDO, into bioPTMEG. “The C4 Platform facility utilises a new process called Advanced ThermoChemical technology that was developed inhouse by CovationBio to create Xatryx products,” says Mosha H. Zhao, marketing director for the C4 Platform. “The first phase of the Qidong plant achieved mechanical completion in April 2026 and has officially initiated production of its first commercial batches of Xatryx, which is designed as a dropin replacement for fossilbased PTMEG.” This compound can be used to make SPORTSTEXTILES ISSUE TWO 2026

elastane, polyurethanes and thermoplastic elastomers. Huafon plans to launch its own a bioelastane. UPM Biochemicals is a newer name in the fibre industry. The Finnish company converts wood into sugar and produces bioMEG, a building block for polyester, among other nonfossil chemicals. It has invested €550 million to build an industrialscale biorefinery in Leuna, west of Leipzig, in Germany. With an announced capacity of 220,000 tonnes per year, the company claims that it is the largest such facility in Europe. Production of bioMEG, bioMPG and ligninbased renewable functional fillers began late last year. The company can also deliver a renewable naphtha from its biorefinery in Lappeenranta, Finland. “Together, these renewable carbon sources enable pathways towards polyester with significantly reduced fossil carbon content and ultimately even 100% woodbased polyester solutions,” says Holger John, sales manager for glycols at a division the company calls UPM Next Generation Renewables. “More broadly, our analysis of future textile pathways shows that the industry’s key challenge is not synthetic fibres themselves, but the fossil carbon on which they currently depend. When comparing different pathways for the textile sector, a key conclusion is that renewable and recycled carbon should not be viewed as competing solutions. The strongest outcomes are achieved when both are allowed to scale together.”
Better biomass Derived from renewable resources, and major agricultural crops such as corn and sugarcane, choosing to use biosynthetics inevitably raises questions about land use, and the long running foodversusfuel debate. As seen earlier, they make up a small portion of textile fibres, and an even smaller part of farming. In its latest report, ‘Biobased Building Blocks and Polymers’ published in February 2026, the Nova Institute in
06
Germany pegs global demand for biomass (for all uses) at 13.7 million tonnes per year. Feed production makes up the majority (57%), and some 0.026% are used to make biopolymers. With regards to land use, it says that the production of 4.5 million tonnes of biobased polymers in 2025 required 3.6 million tonnes of biomass, grown on 0.016% of agricultural land. This, the report notes, is due to the high area efficiency of sugarcane and maize crops, which are the main feedstocks used in the production of biobased polymers. While this data helps clear the confusion on land usage, the issue continues to haunt the biofuels, bioplastics and biopolymers industries. Food sovereignty is a sensitive issue, and many brands and corporations prefer to steer clear of the topic. Biomass is ranked in three categories: food, nonfood and nonagricultural. Firstgeneration feedstocks are derived from maize, sugarcane and sugar beets. Agricultural waste (corn stover, wheat straw) and wood residues make up what are called secondgeneration feedstock. Thirdgeneration ones are those that avoid terrestrial agriculture, the most commonly cited example is algae. Carbon extracted from flue gases is another thirdgeneration, nonfood and nonagricultural source of carbon. Earlier this year, Hyosung announced it had switched from corn to sugarcane, which it sources from Brazil, a country with an overcapacity for sugar production, says Simon WhitmarshKnight, marketing and sustainability director for Hyosung Textiles. This change also “removes one step in the production process as there is no need to convert corn into sugar,” he adds. The resulting bioelastane can now claim 70% biobased content. The company also offers a version that is 98% biomassderived. “It is a combination of 70% from sugarcane and 28% mass balance plantbased biomass,” he says. Other companies are switching from food to

also sees “exciting opportunities in combining Sorona with natural fibres to enhance their performance while maintaining their natural comfort and aesthetics. Sorona helps bring together the best of nature and performance.” It is a key macro trend for Mr WhitmarshKnight, at Hyosung: “Personal wellness drives demand for biobased elastane, and it is particularly important in nexttoskin applications.” With elastane’s biggest producers investing in biopolymers, could bioelastanes be more prevalent than plantderived polyesters or nylons? Maybe not, as the stretch fibre makes up a small portion of a fabric’s composition. Others argue that recycled is easier to sell. For elastane, present only in blends, this is a formidable challenge. Finally, biopolymers suffer from the double meaning of the prefix ‘bio’ in many languages. At a panel talk at Première Vision in September, René Bethmann, senior innovation manager for Vaude, highlighted this point: “Germans are sceptical of biobased polymers, due in part to the double meaning of bio, which also refers to organic. No one questions the technology, but rather the impact on land use and farming. We need to be able to explain this better because consumers have many questions about biobased.” Recycled, he also noted, is an endoflife solution, whereas biobased is a beginningoflife solution. Could this be a first, smart step in helping biosynthetics grow?
nonfood biomass. CovationBio now uses corn cobs to make its Xatryx bioPTMEG. In Italy, Fulgar has reduced corn in favour of castor bean oil in the production of its EVO biopolyamide. A solution that offers better performance, as Daniela Antunes, marketing manager tells Sportstextiles. At a panel talk at Future Fabrics Expo in Brussels last June, Jerry Luo, the cofounder of the Chinese PEF producer LeafBio, said the company had switched to agricultural straw waste in 2025. “In our process, we turn cellulose into glucose to make PEF. We can use cellulose from textiles and cardboard, but textile waste is 50% more expensive than agricultural waste,” he told the audience.
Matching nature All producers of biopolymers claim that their plantbased solutions are dropin replacements for fossilderived chemicals. Biosynthetics are thus virtually indistinguishable from conventional manmade fibres. This is a good point, but not an easy sell. To emphasise their renewable plantbased origins, they are often paired with natural fibres. This trend has been gaining traction amid growing concerns about microplastic pollution and the added pull of a polyester backlash on social media. “In activewear, Renewable Lycra fibre can strengthen the overall materials story, particularly when combined with natural or manmade cellulosic fibres,” says Mr Williamson. At CovationBio, Kiki Chen, in charge of marketing communications for Sorona Apparel,

3M expands Thinsulate and Scotchgard into performance fabrics
U
nveiled during UTMB MontBlanc in Chamonix, the two new platforms represent a significant development for a materials developer traditionally associated with insulation and fabric protection. The move sees 3M extend both Thinsulate and Scotchgard into functional fabrics designed to combine several performance characteristics within a single textile construction, targeting the evolving requirements of outdoor and active apparel. Rather than focusing on a single performance attribute, the new platforms have been developed around the idea that outdoor garments increasingly need to respond to different conditions and levels of activity. For apparel developers, this means balancing properties such as thermal performance, breathability, moisture management, weather protection and weight within the same garment.
Thinsulate moves into multifunctional fabrics 3M Thinsulate Outdoor Comfort has been developed as a dualfunction fabric combining thermal performance, breathability and moisture management. The construction uses a waterrepellent outer surface designed to protect against splashes and light rain, while its inner surface provides moisturewicking performance to move perspiration away from the wearer. A fleece structure is intended to balance two potentially conflicting requirements in active outdoor apparel: allowing heat to escape during periods of activity while providing warmth as temperatures fall or activity levels decrease. This combination positions the platform for garments required to perform across changing temperatures, weather conditions and levels of physical exertion rather than being designed around a single end use.

3M is expanding two of its bestknown textile brands into new areas of the performance apparel market, with the launch of Thinsulate Outdoor Comfort and Scotchgard Outdoor Performance. The development reflects one of the recurring challenges facing designers of performance apparel: managing the relationship between the wearer's activity level and the surrounding environment. During higherintensity activity, breathability and moisture management become increasingly important as the wearer generates heat and perspiration. When activity levels fall, or temperatures drop, retaining warmth becomes a greater consideration. 3M's approach with Outdoor Comfort is to bring these requirements together within one fabric construction rather than treating them as entirely separate functions. The waterrepellent exterior adds another element to the system, providing protection against splashes and light rain while the moisturewicking interior is designed to move perspiration away from the wearer. The result is a material platform intended to support comfort across a broader range of outdoor environments, including periods of higher activity as well as colder, wet or rainy conditions.

A lighter approach from Scotchgard 3M Scotchgard Outdoor Performance, meanwhile, takes a lighterweight approach. The new fabric platform combines water repellency and breathability with a lightweight construction and is designed for changing weather conditions, everyday outdoor activities and commuting. Designed to repel splashes and light rain, the material is intended to reduce the discomfort associated with moisture and wet weather while remaining breathable during activity. Its lightweight construction is also designed to provide a flexible wearing experience, with 3M identifying everyday outdoor activities and commuting among its potential applications. Outdoor Performance brings together water repellency, breathability and a lightweight construction, with the platform designed to support comfort and versatility across changing weather conditions and a range of everyday outdoor activities. The positioning also takes the technology beyond highly specialised outdoor garments and into the increasingly broad area in which performance apparel overlaps with everyday clothing. For textile and apparel developers, that reflects a market in which consumers increasingly expect functional properties from garments that may be worn across different activities and environments rather than exclusively for a particular sport or end use.
Broadening the performance proposition Taken together, the two launches represent a broader move by 3M towards integrated textile solutions. Instead of treating insulation, protection and wearer comfort as entirely separate technologies, the company is seeking to incorporate multiple functional properties within fabric constructions that apparel brands can use to address different performance requirements. 3M said: “Outdoor apparel continues to evolve as consumers expect greater versatility, comfort and performance from every garment. Outdoor Comfort and Outdoor Performance represent an exciting new direction for both the Thinsulate™ and Scotchgard™ brands. By combining multiple functional benefits into innovative fabric constructions, we are giving apparel partners new possibilities to design products for today's outdoor lifestyle.” The development is particularly notable for Thinsulate and Scotchgard because of the established identities of the two brands. Thinsulate has traditionally been associated with lightweight insulation and thermal comfort, while Scotchgard has built its position around protection and enhanced fabric functionality. The new platforms broaden those propositions by combining several wearer benefits within the material itself. For apparel brands, the intention is to provide greater flexibility when developing products expected to perform across changing environments and activity levels.
Inspired by changing outdoor conditions The decision to introduce the new platforms during UTMB MontBlanc also provides a relevant setting for the technologies. Mountain environments can expose users to rapidly changing weather, temperatures and activity levels — the same variables that Outdoor Comfort and Outdoor Performance have been designed to address. For 3M, launching the technologies in Chamonix therefore connects the development of the materials with the realworld conditions encountered by outdoor users. The company accompanied the launch with activities involving
SPORTSTEXTILES SERVING THE PERFORMANCE TEXTILE INDUSTRY SINCE 1995
the international trailrunning community gathered in Chamonix for UTMB week, including a community run with athletes, partners and outdoor enthusiasts. But from a textile perspective, the more significant development is the extension of two established 3M material brands into new functional fabric platforms. By combining properties including moisture management, breathability, water repellency, thermal performance and lightweight comfort in different constructions, 3M is positioning the two platforms around versatility rather than a single performance function. For apparel developers, that creates another approach to designing garments intended to respond to the changing conditions encountered by today's outdoor consumer.

atural performance and wellness are emerging as key drivers of demand, and seamless knitting is answering this call with nextgeneration fibres, smart textiles and digital precision in garmentmaking technology. The evolution of nexttoskin performance was the topic of the very first webinar jointly organised by Performance Days and Sportstextiles, who have created a new platform for innovation and knowledge sharing. The notion of wellness has now gone beyond the spa, says Nichole de Carle, creative director and material innovation specialist, who is also Performance Days’ bodywear curator. It has not only expanded into skincare and food, it is also weaving its way into the textiles we wear next to the skin. “Consumers are monitoring their sleep and people who are active integrate recovery into their routines. So, the question now is how can textiles, which we wear against the skin 24/7, address these new demands?” she asks. For Jillian Samis, Tefron’s head of marketing and design, wellness is an integral part of everyday life. This global manufacturer of seamless knitted apparel is actively seeking to address the many facets of these new consumer expectations. “Our research into recovery sleepwear was sparked by the use of Whoop health trackers, which also monitor sleep,” she says. Taking silk pyjamas as a starting point, the team added infraredreflecting yarns to promote recovery by activating blood flow. “This choice of fibres accompanies a wellness journey, speeds up muscle recovery and complements the smart tech devices that people are increasingly wearing,” she points out.
A new material intelligence German highend wool spinner Südwolle Group is also exploring nextgeneration fibre blends. Its alginate fibremerino wool blend yarns won a Performance Days innovation award last March. The algae fibre is derived from brown seaweed and is the result of a collaboration with a Chinese university. “The algae yarn brings the benefits of strong moisture absorption and a very soft feel Whoop, the maker of health and performance tracking devices, designs apparel with locations to house a wearable pod during workouts.

against the skin. In addition, perhaps surprisingly, it has a high fireresistance. The pure alginate fibre has a limiting oxygen index (LOI) of 45%,” says Lukas Vogl, Südwolle’s marketing specialist and head of Südwebs, its innovation hub. “With these innovation projects, our goal is to expand the industry’s toolbox and offer a platform for customers willing to explore new concepts.” An enhanced, performance silk development will be showcased at the next Performance Days show (Munich, October 13 and 14), teases Ms de Carle. “We are working on a project that pairs silk with graphene and for the new cellulosics forum that will be inaugurated at the show.” The silk fibres provide breathability and the graphene delivers recovery. These properties have been tested and validated, she says. “This introduces a new way to wear silk for an active lifestyle.” Reacting to the bad buzz surrounding polyester, now a synonym for cheap or fake, Lukas Vogl argues that rather than pitting natural fibres against synthetics ones, a new material intelligence is needed. This is a view shared by Jillian Samis: “When you blend synthetics with natural fibres, you get the best of both worlds”. Zoë Rosenberg, Whoop’s lead materials developer for accessories and apparel, agrees that when making fibre decisions, you need to ask yourself what the product is going to be used for: is it for performance or is it for fashion? Whoop makes fitness and health wearables that can be worn on the wrist, as is the custom, or embedded in clothing, to give users more flexibility in how they use the device. The brand’s apparel and accessories range includes smart nooks for a wearable but removable pod, keeping the device in place and positioning it to capture quality data. Whoop currently offers a selection of ‘podenabled’ items, from brassieres and underwear to shorts and teeshirts. It has chosen seamless knitting as the best solution for comfort and performance. “We find seamless knitting useful because you can pattern in functionality as well as varied levels of compression. Our device requires a certain amount of compression to avoid motion artefacts,” says Ms Rosenberg. Approved locations for the Whoop pod include the biceps, the side torso and upper glutes. A more compressive and targeted structure is knitted at these locations to keep the pod close to the skin and prevent excess movement while avoiding compression throughout the entire garment. Seamless knitting is a hightech, zerowaste manufacturing method that has become the industry standard for baselayers, as it enables ventilation, compression, wicking and thermoregulating zones to be engineered into a single garment. “With seamless, you can knit down to the pixel, you can combine different fibres and gauges, while avoiding cutting and sewing,” says Ms Samis. Tefron’s new recovery sleepwear is designed to be worn close to the skin allowing the infraredreflecting yarn to optimally return energy to the body. However, seamless does not necessarily imply tightfitting. “This type of

knitting is historically associated with fitted leggings and sports bras. But we are investigating hybrid constructions that combine seamless with cutandsewn knits to create innovative twoinone solutions,” she notes. Südwolle is also working on a project that challenges the notion that seamless clothing has to be fitted. The results of this research will be presented at Performance Days. A space to watch.
New markets In addition to hybrid constructions and looser shapes, seamless knitting is moving into new markets, such as running and hiking. “There’s a real opportunity for seamless outdoor clothing, and I am not sure consumers have picked up on this,” says Ms De Carle, who believes that seamless can do much more than many people previously thought. She mentions Tefron’s Terrain Collection as a clever take on this new trend. “It combines natural fibres with a mosquitorepellent yarn and is designed for performance. You can climb in these seamless outdoor pieces.” Ms Samis adds that Tefron has also developed performance wool tops with UV protection and ventilation zones that “can easily be worn in everyday life”. The head of marketing and design for Tefron also notes that seamless is inexplicably absent from swimwear, despite being ideally suited to the manufacturing technique. “We could engineer swimwear with compression zones and builtin support for the chest.” Travel wear could benefit from seamless constructions as well. “When considering comfort and how a garment is constructed, there is definitely space to explore. It may not be conventional technical performance, but it does perform for the user,” she adds. These new directions recall the former buzzy athleisure trend. While the term may be dated, all agree that the concept is not. “Many of the garments we see today are athleisure in disguise,” says Mr Vogl. “They may be street casual or business casual, but they have the feel of athleisure: clothing that feels and looks good. In my mind, the properties have evolved even if the style has been left behind.” Ms de Carle sums it up: “Brands have normalised performance beyond exercise. Consumers have moved on from athleisure. It is not dead in the water, but we are now looking to curate a welledited wardrobe. We are dressing for sleep, commuting, work, sports and travel. The thread that connects all of these is wellness.”

dvanced textiletotextile recycling is becoming a reality, and with it the promise of making polyester textiles infinitely recyclable. Unlike mechanical or thermomechanical processes, depolymerisation techniques using solvents or enzymes are said to produce highgrade rPET. Several companies are now moving from demonstration stage to industrial production, with factories under construction at Reju, Circ and Carbios in France, Gr3n in Spain and Syre in Vietnam. The real action in textiletotextile recycling is in fact already up and running in Asia. China’s Jiaren operates a 20,000tonne facility in Shaoxing through a jointventure with Teijin using a technology originally developed by the Japanese company. Another production line is planned in a jointventure with Thailandbased Indorama Ventures, with an announced goal of achieving an annual spinning capacity of 100,000 tonnes of textilerecycled PET. In Australia, Blocktexx runs a 10,000tonne recycling factory for polycotton textile waste in Loganholme, Queensland. In China, ReoEco inaugurated a 10,000tonne facility in Huai’an, Jiangsu, this past August. Its longterm vision is to increase this capacity to 100,000 tonnes in 2027, and 1 million tonnes in 2030. The breakthrough ReoEco claims is that its BioCulus process uses enzymes rather than solvents to depolymerise polyester. Instead of high heat and pressure, enzymatic recycling takes

These conditions result in a lower environmental impact than chemical recycling and require a nontoxic environment to enable the enzymes to work and remain active. “This is the beauty of enzymatic recycling,” says Stefan Edkvist, ReoEco’s business development director. “We are continually filtering out those enzymes that are either too slow or too fast, to keep the best ones for the process.” This has enabled the company to improve their productivity. “Our enzymes are getting stronger and more efficient. Last year, the depolymerisation process took 12 hours, this year, we have reduced that to six to seven hours.” Another claimed advantage of this recycling method is that the enzymes are engineered to target a specific polymer. “By nature, our enzyme focuses on PET and breaks it down into its monomers. Dyes and other chemicals are filtered out. Nonpolyester fibres such as cotton, wool and others are filtered out too,” Mr Edkvist tells

Sportstextiles. These unaltered materials can then be treated by other recyclers. “We send them back to our sorter who recycles that waste into outdoor flooring.” ReoEco produces its own enzymes that convert polyester back into purified terephthalic acid (PTA) and monoethylene glycol (MEG). Mr Edkvist says that the company’s R&D team includes 18 PhDs. The BioCulus process requires textiles containing a minimum of 90% polyester. The company sources postconsumer waste from two collectorsorters located an hour away from the factory. It has also partnered with brands to take in their offcuts and unused bolts of fabric. “We have spent the last three years securing feedstock,” he says, adding that a third collectorsorter has now joined the ecosystem. At the recycling plant, the sorted textile waste undergoes an additional AIpowered sorting to weed out any nonpolyester items that might have slipped into a batch. Mr Edkvist insists on the highly controlled nature of the system in place at ReoEco. “There are more than 1,000 checkpoints throughout the process. If something goes wrong, we need to know fast and fix the problem, no matter what stage it occurs at: sorting, shredding, reactors, filtration, purification or polymerisation.” All of these checkpoints are automated, meaning that once the feedstock arrives at the plant, no further manual operations are required. These multiple screenings also enable ReoEco to claim that BioCulus yields a very pure form of polyester that is higher in quality than standard virgin petrochemical polymers. “This naturally came as a surprise to us when we compared the two. We do not know the reason, but the fact remains. Our process is carried out with great attention to detail,” he says. Since depolymerisation reverts a polymer to its original building blocks, it is difficult to prove the presence of recycled content. Thanks to its integrated production and careful screening, ReoEco has obtained GRS certification for all its products (filament and fabrics). The textile waste feedstock is measured physically. Mr Edkvist admits that it is impossible to be 100% sure with postconsumer waste. To back its claims, ReoEco embeds a DNA tracer in the polymer during the BioCulus process.
A near perfect score ReoEco says it recovers 99% of the polyester input. A near perfect score. At a panel talk held at Première Vision Paris last September, Emmanuel Robin, textile market manager for Carbios, a French company that has also patented an enzymatic recycling process for PET and polyester, claimed a recovery rate of 95%. Blocktexx, which uses a different process called Separation of Fibre Technology (S.O.F.T.), says it reclaims 93% of its polyester and cotton input. A vertically integrated manufacturer, ReoEco produces T2T rPET filaments from the chips and makes knitted and woven fabrics. It also operates a bottle flake recycling facility, with an annual
capacity of 100,000 tonnes. This bottle flake rPET helps to bridge the price gap, as ReoEco offers fabrics made from a blend of 80% postconsumer bottle flakes and 20% postconsumer textile waste. This offers brands a way to gradually increase uptake of T2T rPET in their ranges, by offsetting the higher cost of textiletotextile rPET. Mr Edkvist expects T2T rPET to be available at the same price as bottle flake rPET by the end of next year. “But whether bottle flake or T2T, we need to recycle our waste,” he points out. The business development manager of ReoEco is also intent on reducing other apparel industry impacts, specifically those related to dyeing. This is a mission he first put in practice at SpinDye, a Swedish company specialising in dopedyed yarns, that avoid traditional wet dyeing processes. The first shade ReoEco is offering in its FixDye range of dopedyed yarns is a (blue) black. He is confident that the vision once pursued by SpinDye will now be realised on a much larger scale by ReoEco. “With BioCulus, we went from 500 kg to 10,000 tonnes. This is a true breakthrough for the industry, as it reduces the need for virgin polymers.” He says that what is now critically needed are highvolume customers.

Rather than approaching material selection simply by fibre or construction, organising the collection around finished applications allows development teams to begin with the performance requirements of the product they are creating.
Building a mill partnership Atextile was announced as the first official CORDURA Adventurer™ mill partner during Intertextile Shanghai Apparel Fabrics in August. The Xiamenbased textile manufacturer specialises in performance woven and laminated fabrics for outdoor, sports and workwear markets, with capabilities spanning lamination, coating and functional finishing. The partnership combines Atextile's manufacturing and technical development capabilities with the material expertise, global network and ingredientbrand platform of CORDURA® Advanced Fabrics. “This partnership is about working together to solve real market needs,” says Ryan Castanet, director of business development at CORDURA® Advanced Fabrics. “By collaborating closely with mill partners like Atextile, we can deliver meaningful innovation faster, pairing material performance with a trusted brand platform that helps designers and brands move forward with confidence.” For Atextile, the collaboration also provides a platform through which it can expand its presence within the international outdoor market. “As a strategic partner, CORDURA® brand's empowerment and implementation of products will help us gain a stronger market share, and CORDURA® brand will also bring added endorsement to many brands,” says Figo Wu, CEO of Atextile.
Taking the story through to the finished product The programme extends beyond the fabric itself. Brands selecting qualifying fabrics from the CORDURA Adventurer™ collection will also have access to CORDURA Adventurer™ hangtags and sewin labels, allowing the material technology and ingredientbrand story to remain visible through to the finished garment.
For designers and product developers, the combination of a curated fabric collection, defined application categories and onproduct branding is intended to create a more connected route from initial material selection through to the consumerfacing product. The Performance Days presentation will give European designers, developers and sourcing teams their first opportunity to explore the expanded collection and examine the individual fabric constructions firsthand. Atextile will showcase the 50fabric CORDURA Adventurer™ collection at booth U14 at Performance Days, Munich, October 13–14. The collection will subsequently be presented by CORDURA® at booth 644 at Functional Fabric Fair, Portland, Oregon, October 27–28.

SPORTSTEXTILES POOLED THINKING ON FOOTWEAR RECYCLING
Pooled thinking on footwear recycling
D
utch sustainability hub Fashion for Good does a great job at uniting brands and the supply chain. It organises pilots addressing various challenges, helping to scale up, increase adoption or support with data novel materials and processes. Following seven years of focusing on textiles, in 2024 it announced a series of projects that would apply the research and collaborative development blueprint to the footwear sector, under a banner called Pioneering the Future of Footwear One of the biggest topics taking up headspace in the fashion industry is circularity – how can we keep materials in use longer and recycle elements when they no longer serve their purpose? With an estimated 23.8 billion pairs of shoes produced annually, the vast majority of these ending up in landfill and less than 1% recycled, this is a question that needs some answers, compounded by incoming regulation such as Extended Producer Responsibility schemes, Digital Product Passports and stronger circularity requirements. This is a sticking point for shoe companies – not least because of the multitude of materials, glues and components that they work with. But also in a practical sense. How can shoes be collected and sorted in a way that makes both economic and environmental sense?

Leading brands have supported Fashion for Good pilots to pool knowledge on circular thinking and search for solutions to the complex problems holding footwear recycling back. Collaborative working is the only way, Fashion for Good has concluded. At the start of last year, it launched Closing the Footwear Loop, which brings together 15 brands and four innovators to test ideas and pool resources, orchestrated by Dutch nonprofit Circle Economy. It addresses the lack of endoflife infrastructure, complex multimaterial designs and the need for unified circularity approaches. Fashion for Good describes its findings as the first largescale, productlevel dataset on nonrewearable shoes. “The footwear industry stands at a critical turning point,” says its managing director, Katrin Ley. “With billions of shoes produced annually and 90% ending up in landfills, 'Closing the Footwear Loop' represents our most ambitious effort yet to reimagine how we design, use and dispose of shoes.”

Adidas, Inditex, Otto Group, On, PVH Corp, Reformation, Target, Zalando, Arc'teryx Equipment, Coach, Dr Martens, Decathlon, Deichmann, Deckers Brands, Footwear Distributors and Retailers of America, Lululemon, Puma Group and Vivobarefoot are partners demonstrating a healthy appetite from brands to gain some clarity.

Wheat from the chaff The first phase of the study was conducted through research, stakeholder interviews and an onground analysis. Recycler Modare in Barcelona sorted 7,200 post consumer shoes, finding 4% cream [top] quality, 42% as Grade 2 quality rewearable, and 50% as nonrewearable. The best quality shoes are generally resold in Europe, with lower grades exported to countries such as Pakistan, UAE and India. The report noted the rise of peertopeer trading platforms means the most valuable shoes stay in that system, limiting the value for sorters. From this batch, 1,200 nonrewearable items were sent for analysis by CETIA, a French innovation centre dedicated to the recycling of fashion goods. It is common practice to first shred and later identify and separate footwear materials, meaning that purification and classification is only possible after shredding. However, the team enlisted UKbased Matoha, which adapted its handheld infrared spectroscopy devices from clothing for this project. These machines take a reading before the shoe is physically broken down. “In practical terms, this means shoes could be scanned at collection, sorting or disassembly stages to make faster decisions about reuse, resale, repair or recycling routes,” Chris Newton, Matoha’s chief commercial officer, tells Sportstextiles. “The benefit of rapid identification technology is speed and better decisionmaking. If operators can quickly understand what they are handling, they can sort materials more effectively, reduce contamination and potentially direct products into highervalue reuse or recycling streams.” However, these devices face constraints with footwear. NIR scanners could not recognise 40% of the soles’ makeup. One of the main reasons is the inability to recognise carbon black, which does not reflect light that can be read by spectrometers, and which made up a third of the soles in the sample. The scanners also have problems with leather, due to the way the tanning process alters the surface, as well as any material that is heavily coated, or with thick prints, or blends of certain materials. Adhesives and dirt can also impact readings. In many cases, scanning specific exposed components or partially disassembled sections gives the best results, says Newton. “We see the technology as a powerful decisionsupport tool rather than a ‘magic scanner’ that solves every challenge instantly.”
Flies in the ointment The complexity of shoes compounds the problem. A single running shoe can contain up to 65 parts assembled through more than 360 steps. In the sample, half of the shoes were bonded with

”
strong adhesives, which prevents the clean separation and identification required for highvalue closedloop recycling. Even seemingly simple shoes combine multiple polymers, foams, textiles, rubbers and glues. Only 10% had midsoles and outsoles made of the same material, and those made from SBR (styrene butadiene rubber) and vulcanised rubber cannot be broken down chemically due to the crosslinkers. SBS (styrenebutadienestyrene), TPU (thermoplastic polyurethane) and EVA (ethylenevinyl acetate) are technically capable of mechanical recycling but need to be isolated from adhesives and thermoset contaminants. All of these stages add time, energy and, crucially, cost. In terms of disassembly, another major problem was noted: around 90% of shoes had external disruptors such as logos, patches and trims, and 22% of the shoes had internal disruptors including adhesives, metals, hardpoints and blended materials.
Added insight To complement the study, Spanish sorter Picvisa and French company The 8 Impact also conducted trials. To meet the requirements for Picvisa’s optical sorting machinery, a footwear sample was mechanically shredded and separated by density through machinery made by Eldan Recycling. At

this stage, material loss varied depending on the type of shoe: for boots, around a quarter of the material was lost, but for performance shoes, this rose to 70%. The flakes were then sorted using Picvisa’s Ecoflake machine. Its study showed while high levels of efficiency can be achieved under controlled conditions, significant challenges remain when dealing with complex waste streams; the shoes need better preprocessing and separating to gain more acceptable results. Impact 8 gave a more positive verdict. The company is based near Lyon, and runs a successful line transforming old trainers and tennis balls into compounds for outsoles. Presorting is conducted by collectors and social enterprises, ensuring consistency and low variability. Impact 8 shreds then separates the materials, recovering the rubber at a rate of 99% purity. This is ground to a fine powder that forms the base of the new soles. The French company concludes “endtoend sneaker recycling is technically viable, industrially scalable and capable of delivering recycled materials that are functionally competitive with virgin materials”. Recycled rubber and EVA could achieve price parity through volume and margin control, it says, but this requires early collaboration with design and supply chain teams as well as offtake commitments from brands and manufacturers.
First findings At the start of this year, the Closing the Footwear Loop partners met at Adidas’ headquarters in Germany to discuss initial findings. Adidas, Decathlon, Footwear Innovation Foundation and Vivobarefoot shared their stories, and materials innovators pitched their products. The first report from the project, published in June, concludes gains can be made from making shoes with fewer blended materials, avoiding black, using fewer heavy coatings, and reducing decorative disruptors. Data collection throughout the manufacturing processes will be essential to enhance sorting accuracy, it says. There needs to be infrastructure and systemlevel improvements for feedstock accessibility, including preprocessing, to enable component separation, contaminant removal and refurbishment. With a quarter of the unwearable shoes found to have no damage, there also need to be more education on the consumer side, with quick wins including tying shoelaces together when they are disposed of, so the pair doesn’t separate in transit. Interviews are now being held regarding the design process to understand how visual guidance for stakeholders can be developed, and a pilot with disassembly specialist Idelam to separate out TPU/PU, EVA, leather and rubber using supercritical CO2 has been agreed. The teams want to work out how circularity can be designed in from the start, and how deeper connections can be made across the chain to enable collectors, sorters and recyclers to work more closely with brands. “The path forward involves strengthening circular design practices, promoting the rewear potential, improving sorting and preprocessing

capacity and technology, and establishing robust data systems,” concludes the report. “Transforming nonrewearable shoes from a complex waste challenge into a valuable material resource is challenging but possible through collaborative intervention. By grounding policy and innovation in evidence, the footwear sector can take decisive steps towards closing the loop.”
NATURE’S BOUNTY In a separate footwear pilot, Fashion for Good and its partners are analysing whether biobased polymers could replace petrobased plastics for soling. Commonly made from PU, TPU, EVA and rubber, soles are said to represent 40% of the total mass of a shoe, making a significant contribution to its carbon footprint. The Next Stride project unites Adidas, Target and Zalando with material innovators Algenesis Labs, Balena, Evoco, Kuori and Yulex, with UKbased SATRA testing the performance. Gudrun Messias, director of sustainability direction at adidas, said: “We will work with innovators to explore if biobased materials can potentially lower the environmental impact of footwear soles while at the same time meeting or even enhancing the highperformance standards our athletes and consumers expect from Adidas products.” The project will conclude this autumn.
THE 8 IMPACT LAUNCHES OKTARA French circular tech company The 8 Impact exhibited in the innovation section of Première Vision in September as one of the finalists of the ANDAM (National Association for the Development of Fashion Arts) prize for 2026. Founders Marie SoudréRichard and Hélène Guerret have developed and patented a fully mechanical recycling process for rubber found in postconsumer footwear and tennis balls. After a disassembly process, the rubber is decontaminated, achieving a purity rate of close to 100%, the company said. The regenerated rubber is then mixed with virgin material, and the final product, branded Oktara, has 30% recycled content. “This is a high proportion for postconsumer waste,” Marie SoudréRichard told Sportstextiles. The decontamination process is essential in working with postconsumer waste and guarantees that Oktara is REACh compliant and free of any toxic substances. Some of the coloured speckles are deliberately kept in in to show traces of the product’s former life. Oktara has already been used by a number of footwear manufacturers, including Veja, Eram and Decathlon. Outdoor brands and even companies in trail running are currently testing it. Earlier this year, the startup raised €2 million from a group of investors including Collateral Good, Bpifrance, Makesense, UI Investissement and Fashion for Good.

A
n ingredient brand that has a strong reputation for enhancing safety for snowsports enthusiasts is now taking large strides in yearround apparel, footwear and equipment. Stockholmbased Recco has been supplying its twocomponent safety technology to winter sports brands and, crucially, to searchandrescue (SAR) teams since the 1980s. Since 2015, it has also been working with brands that want to use the technology in products for hiking, trekking, trailrunning, biking and other activities that help people enjoy the mountains all year round. “This part of the business is growing more and more,” says Recco’s head of brand and marketing, Julia Granhed. The part of the solution that goes into outdoor products is a reflector. Following application instructions from Recco, brands or their manufacturing partners incorporate these reflectors into their products as an integral component. There are several versions, in different sizes and constructions, but each “weighs nothing”, Ms Granhed says, and adds little expense.
Mirror images These reflectors are a passive technology, she explains. They require no battery or charge. They function like a mirror. The second part of the Recco system is a detector that, following the

Safety system developer Recco is still snowsportsfocused but is encountering increasing brand demand for its reflectors in trekking, cycling and trailrunning collections too. same analogy, functions like a flashlight. Point a flashlight at a mirror and the light shines back. Point a Recco detector at one of the reflectors and it responds. This works using harmonic radar. The detector emits a radio frequency signal and the reflector sends a signal back. “It is important for us to keep working on both parts of the system,” Ms Granhed says. Brands have been able to incorporate the reflectors into yearround products without any special considerations. The system operates in exactly the same way. The reflectors are now in jackets, running vests and other garments in collections from brands including Arc’teryx, Helly Hansen, Scott, Rab, Patagonia and Mammut. They are in footwear from Scarpa, Zamberlan, Asolo and Hoka. They are also in mountainbiking backpacks from CamelBak and in cycling helmets as well as ski helmets from safety helmet specialist POC.

“
Walking and running may seem easy activities, but people need to know how to prepare, how to act and how to stay safe.
JULIA GRANHED, RECCO
”
In season, out of season There are several reasons for this widening appeal. These activities are more popular than ever, Julia Granhed continues. And she makes it clear that the rescue community has also been pushing for yearlong options for using Recco detectors to find people. “Less snow and shorter winters are part of this,” she explains. “Resorts are having more visitors outside the ski season and brands think that there is a growing need for safety education in these environments. Walking and running may seem easy activities, but people need to know how to prepare, how to act and how to stay safe.” A tripplan and a charged phone are commonsense components of this. Recco reflectors can be too, plus making sure friends or family members know an intrepid trekker is Reccoequipped. The company has begun offering standalone reflectors that people can attach easily to a backpack or a helmet, but it is committed to continue working with brands and hopes more of them will integrate the unintrusive technology into gear for spring, summer, autumn and winter.
Lived experience Extensive testing and lived experience have helped Recco and rescue organisations work out the best ways to integrate the reflectors into products and the best way to receive a signal from them when the circumstances require. For example, the positioning of the reflectors matters. An ideal place to put them in a jacket, Julia Granhed explains, is in the brim of the hood, just above eyelevel, or at the nape of the neck, where there is a natural curve. Helly Hansen places reflectors in jackets and trousers that outdoor enthusiasts may wear together. In these cases, Recco’s suggestion is that the brand put the reflector near the right shoulder of the jacket but in the left leg of the trousers, or viceversa. The explanation for this brings us to the second part of the twocomponent solution. The setup needs to make the exchange with the detector as easy as possible to make finding a stricken person as likely as possible. The recommended placements of reflectors are based on extensive testing and research, in order to guarantee optimal performance of the system. Also, the Recco system does not work if the reflectors are under water,
but the handheld detector can pick up a return signal from up to 80 metres through the air or from 30 metres through snow. Attached to a helicopter, the SAR will pick up the signal at a height of 100 metres. It is this that makes it an efficient way to search large areas for lost people in the outdoors.
Since the 1980s, search and rescue teams have been using Recco technology to help them find avalanche victims. Now the technology’s appeal is widening. CREDIT: RECCO
Extra eyes One of the organisations that has built up long experience of testing and deploying the technology is pioneering Swiss rescue organisation Air Zermatt. This organisation has been using helicopters to find climbers and skiers on the Matterhorn and in the surrounding area for almost 60 years. It was an early supporter of the Recco system and continues to use the technology and to work with the developer on new ideas. There are handheld detectors now that weigh 900 grammes and are about the same size as a book, Ms Granhed says. This means members of a ski patrol and SAR team can carry the technology in a backpack. In the technology provider’s early years, its handheld detectors weighed 16 kilos. A detector that helicopter SAR crews can carry as a payload is heavier, weighing 80 kilos, to prevent it

from swinging around too much. She explains that airborne and groundbased search teams work well together, each with their own detection technology. “If you fly over a field, say, it is striking how easy it is to spot bright colours. POC has helmets in bright pink, orange or yellow and other easytosee colours. This is a great idea. Looking for someone wearing black or dark green is not so easy, especially if there are trees in the area.” Harmonic radar’s superpower is that it can pick out targets in highclutter areas. SAR specialists have told Recco that the technology can serve as extra eyes for them, eyes that can see objects the human eye cannot. And if a signal does come through, it will often be faster to share the location with quick, mobile colleagues on the ground and let them reach the person in trouble.
A problem to solve It was Julia Granhed’s father, Magnus, who founded Recco. He had lost a friend in an avalanche in Åre in the early 1970s; and took part in the search and rescue. “The rescue team had dogs, but there was no real use of any electronic tools,” the founder’s daughter says. “Transceivers existed, but their use was very limited in those days. Magnus had a Master of Science in Engineering and his two passions are skiing and technology. So, he had knowledge and a big interest in solving this particular problem.” These days, backcountry skiers and others who go off the beaten track will carry avalanche transceivers, smart phones, GPS trackers, a power bank and other tools for staying safe and searchable. Having Recco reflectors in one or more component of their kit is a complement, not a replacement, Julia Granhed insists. She sees it very clearly: “You can argue that GPS is better or that an iPhone is better, but why compare? Why choose? All tools are good, but you never know if one will run out of battery or where and when the
22
signal may disappear. If you also add a Recco reflector, you optimise your chances.” Fresh from a discussion she took part in with cycling, ski and running brand Scott at the 2026 Ultra Trail of Mont Blanc event in Chamonix at the end of August, she says Recco reflectors are not about adding performance to a product. Instead, they add to safety. “This is like insurance,” she explains. “It is something you hope you will never need to use, but you know you should have it just in case.” She argues that what Recco offers can also help brands by giving them something important to include in their dialogue with consumers. She also thinks acting as a bridge between outdoor brands and the SAR community is an important service, one that could help save time and money when an incident occurs, one that can make the search process safer for rescuers, one that can save lives. Safety helmet specialist POC is among the brands that have begun fitting Recco reflectors into products for year-round use. CREDIT: RECCO

SPORTSTEXTILES A MILE IN THESE SHOES
A mile in these shoes
S
cottish middledistance athlete Josh Kerr has broken the world record for the mile. He achieved the feat in July, running the distance (just over 1,600 metres) in 3 minutes, 42.6 seconds. This breaks the previous record, which had stood for 27 years, by half a second. He said afterwards that breaking the mile record had been his main goal for this year and that he had planned meticulously for his recordbreaking run, which came at a wider athletics event at the London Stadium. This preparation included working intensely with footwear brand Brooks Running to develop a pair of custom, raceday spikes. The Seattlebased company called the new shoe the Hyperion 222 because the whole project had a clear target from the start: for Josh Kerr to complete the distance in 3 minutes 42, working out at 222 seconds. Originally from Edinburgh, Josh Kerr became a Brooks athlete in 2018 after completing a highly successful college athletics career while studying at the University of New Mexico. He pitched Project 222 to the company in 2025 and serious work to make the dream come true began in March this year.
History rewritten The Hyperion 222 shoe is the result of what the company has called “rigorous testing”, which took into account the athlete’s individual biomechanics and racing rhythm. Features in the finished shoe include a finetuned carbon plate system and a oneofakind upper. Brooks also supplied a raceday speed suit featuring aerodynamic and temperatureregulating functionality. Josh Kerr was the sole tester of the suit, which Brooks said contained “our lightest materials ever” to allow the athlete to focus solely on his recordattempt. With the new record in the bag, Brooks said: “When preparation meets belief, history can be rewritten.”
Target date Josh Kerr went public with the Project 222 plans in March. He says now that committing this early to a specific date [the London Stadium event was already in the calendar for July 18] helped. “It meant there was no turning back,” he remarks. “Everything was built around that one day. It was a pressureday, but I think you have to have that pressure.” Pacemakers were part of the recordattempt, but it was still what the athlete refers to as “a real race”, and he thinks that helped too, as did having “a team of incredible, worldclass people” working with him. March to July is a long time to prepare for a run that you hope will last only 222 seconds. There was, immediately, a lot of publicity about it and many media demands. There were also lots of training sessions to work through, with

FOOTWEAR TECHNOLOGY
Meticulous detail went into a oneoff shoe that Brooks Running developed for one athlete in one race this summer. The result is a new world record for the mile. injuryavoidance one of the key objectives, and a strict diet to follow. “Then there were the mindset problems from the pressure I was under,” he says. “It all had to work together.” He makes the point that there are many opportunities when running, say, a twohour marathon to control the variables that can occur. You have time to make splits faster or slower if, say, the wind conditions change. There is time to work out the strategies other runners are deploying and decide how best to respond to them. “When you only have 3 minutes, 42 seconds’ worth of variables, there are not that many things you can do,” he observes.
Personal best This means preparation was almost everything and, clearly, this includes the shoes. The Hyperion 222 were completely custommade for this particular athlete to run a worldrecord time over this specific distance. They were built around his unique footstrike using a last moulded from his foot. Each shoe has “an extreme rocker geometry”, which meant the wearer could launch himself off the toe instantly, with this asymmetrical pushoff offering what the company has called “an ultraaggressive ride”. The shoe also features an optimised foam compound for cushioning. Brooks has not revealed the composition of the foam, but it was able to keep the weight of each shoe down to a reported 100 grammes by measuring exactly how much foam to use (to suit Josh Kerr’s body weight) and where in the shoe to put it. For example, the athlete’s landing pattern is forefootbiased, making less foam in the heel possible. The carbonfibre plate, which Brooks has described as the stiffest plate it has ever made, has integrated traction and titanium pins for what it terms “fulltilt racing”.
Technology waits for no one The new mile worldrecordholder says he is completely convinced that he could only have run the time he achieved in the specific shoes he developed with Brooks. He says technology will continue to advance and, as a consequence, record times for the mile, the marathon and most other distances will continue to come down. But running shoes have undergone countless iterations and

improvements since previous worldrecord holder, Moroccan athlete Hicham El Guerrouj ran the mile in 3 minutes, 43.13 seconds. That was in Rome in 1999. All of the advances in footwear materials and construction that have taken place in the whole of the twentyfirst century so far were not enough to beat that time, until now. In general, one advantage today’s athletes have from recent footwear construction developments, according to Josh Kerr, is that lighter weights, greater spring, increased comfort and protection mean that training sessions, as well as races, are taking less toll on runners’ feet and bodies. This means recovery between training and events takes less time and no more “hobbling around on a Saturday” after a week’s work. The Hyperion 222 is special, though. There are unconfirmed reports that a very limitededition public version of the shoe may become available, but it is, essentially, a oneoff.
Head of sports marketing at Brooks, Garrett Heath, says the whole of Project 222 was historic, for the company, the athlete and for the sport. “Josh set out to chase one of the toughest records in athletics and succeeded through courage, preparation and belief. We are honoured to have supported him on this journey.” Immediately after his momentous run on July 18, Josh Kerr said the Brooks team, “the people who created the spikes”, were fundamental in creating the new record and that he got over the line in 222 seconds because of the job that they had done.

SPORTSTEXTILES WATER WORRIES
Water worries
C
otton Australia, the main representative body for cotton growers there, has contributed a detailed submission to a review of national water conservation strategies. Australia approved a farreaching programme through its Water Act 2007. Almost 20 years on, it is this act that is now subject to a formal, independent review. In its submission to the review, Cotton Australia has argued that the focus should be on “getting better results from the system we have”, rather than what it called “another round of major changes”. General manager of the organisation, Michael Murray, says the review offers an opportunity to take stock of what Australia has already achieved and focus on what will make the biggest difference now to farmers and to rural communities. “We need to focus on getting better outcomes from the system we have,” Mr Murray says, “while giving growers and regional communities the certainty they need to plan for the future.”
Millennium Drought Australia brought in the Water Act 2007 because the start of this century was a time of a severe lack of rainfall, especially in the south and southeast of the country. This period is now known as the Millennium Drought. This began in the late 1990s following a strong El Niño weather pattern in the winter (July and August) of 1995. By

SUSTAINABILITY
The representative body of cotton farmers in Australia has said an independent water review should focus on full implementation of current water management policies rather than try to develop new ones. 2003, reports were calling it the worst drought since Europeans first settled in Australia. It took until 2010 or 2011 for the drought to break. Cottonproducing regions were severely affected. Records show that cotton farmers in Menindee in New South Wales and Biloela in Queensland, for example, reported zero cotton production at times during this period. There are widespread reports of the El Niño weather pattern that is developing now being the strongest on record and this has led to speculation, in Australia and elsewhere, of important consequences, including conditions being hotter and drier than average in the southern hemisphere summer of 20262027. The official line from Australia’s Bureau of Meteorology is that no two El Niño patterns are the same and that a strong El Niño does not necessarily mean drought in Australia. There have been occasions when a

”
of water consumed) of cotton farmers in Australia has improved by more than 50% since 1997. Nevertheless, even in Australia, cotton production is a significant user of water resources. Cotton Australia estimates that its members will consume between 6 million and 7 million litres of water per hectare. Most of Australia’s cotton farms are in the Murray Darling Basin. This is an area that covers more than 1 million squarekilometres of landmass, with six of Australia’s seven longest rivers flowing through it. In addition to cotton, it is of critical importance to food production in Australia. The effects of the Millennium Drought there led to the government to form a specific MurrayDarling Basin Plan after the Water Act 2007 came into law. Tensions built up because the federal government pushed to take over the management of the river system from the states (Queensland, New South Wales, Victoria and South Australia) and territory (Australian Capital Territory) that share the basin’s land and water. Some of those tensions remain. strong El Niño has led to more, not less rain there. “El Niño is only one factor,” the bureau insists. In any case, this is not the reason for holding a review of the Water Act 2007 now. There was a stipulation in the 2007 act for a review to take place within 20 years; this is why the government has set up scrutiny of it now. The independent review launched in March 2026. There was indepth consultation with representatives of Australia’s first nations in May, followed by a public consultation exercise that finished in August. There will be a draft report in November, with a final report going to government ministers at the end of February 2027.
Better than average Setting the scene for the cotton sector’s contribution to the consultation, Michael Murray explains that the organisation he leads represents around 1,500 cotton growers. For context, the Indian government puts the number of cotton farms there at around 6 million. Australia’s cotton industry has been the subject of praise from the national government, specifically from the department of agriculture, water and environment, which has claimed producers of the fibre in Australia have achieved waterefficiency levels that are three times better than the global average. Official figures also show that the wateruse productivity (a reference to output for the volume
What the cotton industry has asked for Cotton Australia’s submission sets out 24 recommendations covering water entitlements, markets, environmental outcomes, planning, regulation and regional communities. The recommendations include an appeal to have market needs as the numberone priority when the authorities take decisions on reallocating water resources from one state to another. The list also includes a request that “genuine stakeholder consultation” take place before and after any new legislation on water is drafted. The cotton organisation also calls on the federal government of Australia to resist “tilting its focus” towards the environmental ambitions that the 2007 act lays out. Its fear is that this would come at the possible expense of social and economic outcomes, which Cotton Australia argues are just as important. Of course the environmental aims are important too. In some cases, Australia has obligations under international treaties to preserve wetlands, to protect migratory species and so on. “The Water Act remains fundamentally fit for purpose,” Cotton Australia insists. “The next phase should focus on practical implementation, evidencebased decision making, market confidence and longterm resilience. Continued investment in infrastructure, environmental delivery, community capacity and transparent governance will provide greater returns than further regulatory complexity.”

Warpspeed: Liebaert takes aerodynamic performance from fabric to finished garment
B
uilt on the company's Nanostitch platform, Warpspeed has been developed for brands seeking aerodynamic performance without compromising the fit and comfort required in closefitting sports apparel.
Built on the finest warp knitting machines in the world Warpspeed is produced on custommade warp knitting machines that Liebaert has spent decades refining — widely regarded as the finest in the world for this class of construction. The equipment enables Warpspeed's engineered jacquard geometries to be knitted directly into the fabric, achieving a level of surface uniformity and dimensional control that standard knitting machinery simply can't replicate. Rather than adding a separate aerodynamic treatment, the surface structure is integral to the textile itself. The same dense, precisely controlled knit also delivers the fourway stretch and secondskin hand feel for which Nanostitch is known.
Tested at the fabric level — and the garment level Windtunnel testing is standard practice in aerodynamic fabric development, but Liebaert's work on Warpspeed demonstrates how sensitive aerodynamic performance can be to changes in textile construction. Testing at Bike Valley in Belgium on a 110mm cylinder showed that CS 2915 WATT, a polyamidebased construction, recorded a 23.1% lower CdA than the naked reference at 10 m/s. The development programme also revealed that changing the yarn can change the aerodynamic characteristics of the fabric. Liebaert found that the polyamide (PA) version of WATT

Liebaert's new Warpspeed family combines engineered aerodynamic surfaces with fourway stretch and a secondskin feel — with performance tested at both fabric and finishedgarment level. outperformed the polyester (PES) version tested, demonstrating that performance cannot necessarily be attributed to surface geometry alone. With CS 2324 TRCK, however, the polyamide and polyester versions delivered broadly similar results, suggesting that the influence of fibre choice can itself vary according to textile construction. Perhaps most intriguing is a development currently being explored by Liebaert. When the polyester CS 2324 TRCK fabric was tested inside out, changing the surface presented to the airflow, it produced a substantial reduction in CdA at higher speeds. This construction remains under development. The results demonstrate how yarn selection, knitted geometry, surface orientation and operating speed can all influence aerodynamic performance — supporting Liebaert's decision to develop Warpspeed around speed profiles rather than individual sports.

Testing carried out at Bike Valley in Belgium on a 110mm cylinder showed that CS 2915 WATT, a polyamide-based construction, recorded a 23.1% lower CdA than the naked reference at 10m/s. ==>CS 2324 TRCK, a polyamidebased construction, recorded a 23.1% lower CdA than the naked reference at 8m/s.
Liebaert also tests completed Warpspeed garments in the wind tunnel, allowing seams, panel transitions, garment construction and body position to be taken into account. A fabric that performs well in isolation can behave differently once cut, sewn and worn in motion. Finishedgarment testing therefore provides brands with aerodynamic data that more closely reflects conditions encountered by an athlete in use. A full Warpspeed report covering the windtunnel methodology and results is available to brands on request.
WATT and TRCK: built around speed profiles Rather than developing separate fabrics for individual sports, Liebaert has organised Warpspeed around two principal constructions — WATT and TRCK. WATT has been developed for sustained highspeed effort, including road racing, triathlon and time trial, where aerodynamic drag is a major consideration. TRCK is designed for more variable speeds and riding conditions, including track and gravel applications, where airflow and the interaction between athlete, textile surface and surrounding conditions present different requirements. Defining fabrics according to speed profile rather than sport also opens possibilities in other categories. Speed skating, for example, shares characteristics with the sustainedspeed profile addressed by WATT. For brands, development can therefore begin with the garment's intended speed, conditions and use case rather than requiring an entirely separate fabric for every sporting category.
Made in Europe, backed by 135 years Warpspeed is produced entirely at Liebaert's facility in Deinze, Belgium, with knitting, dyeing and finishing on one production site, giving the company control over manufacture and providing customers with production traceability. Liebaert holds ISO 9001, ISO 14001 and ISO 50001 certifications, together with STeP certification and a toplevel DETOX TO ZERO assessment. The fifthgeneration, familyowned company says it reinvests more than 10% of annual revenue in technologies aimed at reducing its environmental footprint, alongside continued investment in manufacturing and textile innovation.

One platform, three performance directions Warpspeed sits alongside two other technologies built on Nanostitch: Graphecool™, a graphenebased cooling technology for hotweather performance, and Thermal, designed for heat retention in cold conditions. All three share the same underlying platform and Liebaert's Belgian manufacturing operation, allowing brands to develop aerodynamic, cooling and thermal products through one textile platform and manufacturing partner.
From Performance Days to product development Warpspeed will make its soft launch at Performance Days in Munich in October, where brands and product developers can see the WATT and TRCK fabrics and discuss potential applications with Liebaert. Following the launch, brands can request samples, technical data sheets and consultation to match applications to the appropriate construction and speed profile.

SPORTSTEXTILES VALUE THAT LASTS
Value that lasts
K
eela Outdoors has been repairing clothing in the UK since it was launched in 1989, but has recently formalised its circular strategy through The Legacy Project. This includes Reclaim, where surplus fabric is made into something new; the Clothing Hospital, which repairs wearable gear; and Second Life, where endoflife gear is given new purpose. Sales director Samantha Fernando explains how this feeds into a wider philosophy of encouraging consumers to extend garments’ lifespan while lessening impact on the planet. Can you tell us about Keela’s circular strategy and how this feeds into The Legacy Project? We are a manufacturer; that’s a little bit different from other brands. For us, it starts with making kit that lasts, then helping people keep it in use for as long as possible through correct care and repair, if needed. Repair has been part of what we do for decades, and The Legacy Project brings that together with looking at how garments can be repurposed when they’re no longer suitable for their original job. It’s about seeing what still has value rather than automatically treating an old garment as waste. Because we own and operate our manufacturing facilities, we have the people, skills and equipment to do much of this inhouse. That gives us a real opportunity to learn from the kit that comes back and feed those lessons into future designs.

DIALOGUE
Samantha Fernando, Sales director for Keela Outdoors. Can you tell us a bit more about Keela’s manufacturing footprint? We have a manufacturing facility in Glenrothes, Scotland, and we’ve got a 100% owned manufacturing unit in Sri Lanka, which our senior managers regularly visit. This footprint makes us flexible. During COVID, for example, in Scotland, we made 750,000 certified gowns for the National Health Service and repurposed our manufacturing facilities for them over two years. The gowns were all manufactured in the UK and the fabric was made in Dundee, so that helped the government reduce supply chain vulnerability.
Sam Fernando, sales director at the family-run company, says the garments offer protection against the wildest of conditions. ALL CREDITS: KEELA OUTDOORS
How much do you make in the UK versus in Sri Lanka? Sri Lanka is our main factory. We do short runs in Scotland, but also a lot of premium products. Liam Gallagher wore one of our jackets at Glastonbury in the 1990s, and when Oasis had their revival in summer 2025, the fans started asking about the jacket. So, we redid that jacket exactly as it was. It was part of our Albion Collection, made in the UK, and it sold out in a matter of hours.

Keela’s Prosport Jacket features a waterproof, windproof and highly breathable 2-layer hard shell, with comfortable four-way stretch for freedom of movement.
We also do special measures and help people to solve problems. For instance, the curling GB Paralympic team needed trousers that didn’t have zips for their wheelchair users. We have that capability. How does the manufacturing set-up feed into circular thinking, and how do you promote it? As a manufacturer, you always end up with little bits of fabrics, and mills often don’t have a way to get rid of it. We’ve been creating products out of this, such as a jacket made from mixed tapes and different kinds of fabrics. At the Outdoor Trade Show in Liverpool, we brought a sewing machine to demonstrate how easy it is to repair and repurpose products. I turned cuffs with PrimaLoft insulation in into a pocket for my iPhone, and made dry bags to put shoes in. If I can do it, anybody can do it! It’s about getting people to think about repairing and repurposing rather than throwing stuff away. Is this one of the services you offer in Scotland? We have created YouTube videos teaching people how to do it, but they can send product back to us, too. We had a lady whose husband had died, and she didn’t want to get rid of his jacket. So, we turned it into a backpack so that it could still be with her when she goes walking in the mountains. How do you spread the word about this? It’s not necessarily about the PR of companies doing repairs, it’s also thinking about the bigger picture. We promote using a 30degree wash. The impact of 10 million people in the UK washing at 30 degrees rather than 40 in a year is equivalent to 1,500 homes’ annual energy use. We also promote “wear more, wash less”. We’re very much a society that will wash trousers after a day, whereas the older generation wore things for a much longer time and that alone improves the footprint. Do you also use finishes that might promote longer wear? We use Polygiene’s antimicrobial finishes, to help things stay fresh. There is research that shows – depending on the product and what it is used for – 30% of a footprint is to do with the purchase but the other 70% is actually about your use and the eventual disposal. So, yes, we need to do all the good stuff with the product, but if we can also encourage our customers to wear more, wash less, and then also wash more effectively, care for, repair when they can, and recycle appropriately at the end, that’s a really good outcome.
We’re going to be expanding on this. We do a lot with outdoor professionals, for instance in the public sector. We can show them how to do a quick repair on a hill, helping to extend the life of the garment. Can you tell us where the company’s main markets are? Keela is predominantly UK, but we also do big contracts overseas, for instance for outdoor professionals such as rescue teams, where the garments need to do the job. How do you find out about material developments for these high-performance fabrics? We have excellent relationships with R&D facilities and mills that have been built up through decades of partnership and collaboration. In addition, we visit, we inhouse research and often new innovators come to us first. Can you tell us about the benefits of your Insect Sheild range? Insect Shield is from a US company whose insectrepellent treatment is bonded to the fabric fibres. It’s designed to last through repeated washing, which makes it particularly useful for people who spend their working day outdoors. Here in Scotland, we’re all familiar with midges, but ticks are another concern because of the potentially serious illnesses they can carry. One of our customers is a wellknown wildlife photographer who spends a lot of time lying in fields to get his shots. He’s told us it’s made a huge difference to

how he works, giving him extra reassurance (although checking for ticks is still important!). We’ve always seen the value for outdoor professionals, but there’s growing interest from people heading into the hills for leisure, too. With more people trail running, we’re extending the range into socks and accessories, and we’ve now added Insect Shield to leggings as well. What is Keela best known for? We are not fast fashion. We have mountain eering jackets that nothing gets through. One has been out for about 25 years, and everybody loves it. We also use a lot of PrimaLoft in our insulation, because we think the way they manufacture their product is great. Our System Dual Protection (SDP) received a Queen’s Award for Enterprise. The twolayer system uses an outer fabric that is waterproof, breathable and tape sealed. We use a technology that can suck away condensation in liquid or gas form from an air gap and a membrane means it can’t go back in. We’re an engineering company so we’ve looked at it from a physics point of view: it doesn’t matter how good we make that fabric, it’s always going to get clogged with water or dirt, and therefore can’t breathe. So, by doing a “double glazing”, like a house, you don’t get the condensation forming in quite the same way. All our top jackets have this. What was it like to receive the Queen’s award? It was great to get into the taxi and say, “Take us to Buckingham Palace!” and to meet the Queen. Prince Philip and Princess Anne and other members of the royal family were around. It was a brilliant day. So, Keela is family business? Yes, my father founded it in the 1980s. I joined later and did repping for seven years and loved it. Then I moved back to Scotland and worked my way up. You have to put a lot of blood, sweat and tears into a family business, you never get time off!
What other products are your best sellers? We do some threelayer jackets that people can easily pack away. We have a long jacket that is waterproof and breathable, using the same fabric we use in our mountain jackets. It looks like a fashion jacket, but it has all the features and performance you need, including a twoway zip and PrimaLoft Gold, making it great for dog walkers or wearing in the city. Do you feel like your customers understand the ingredient brands? Yes, many outdoor professionals have favourite fabrics and technologies, such as PrimaLoft, Cordura and even SDP. They’re keen to understand the technical details and have a real appreciation for the innovation behind them and how that translates into performance.

A jacket containing Ventile fabric is given a new lease of life at the Glenrothes factory.
Are there any new fabrics in the collection that are particularly interesting? We have one that offers 30,000/30,000 for waterproofness / breathability, but it’s so light. It packs down to almost nothing and weighs similar to a Mars bar. Where do you source your fabrics? We work with British mills such as British Millerain, as well as mills across Europe and Taiwan. We greatly value these partnerships, many of which have developed over decades. Can you tell us more about your collaborations? We really enjoy working with people, and one of our collaborations is with the National Trust for Scotland. Our ‘Where Nature Leads’ range takes inspiration from places they care for, including Glencoe, St Kilda, Staffa and Ben Lomond, with a percentage of sales going back to help protect them. What we hadn’t realised was that some of their pathbuilding teams were already wearing our kit – and apparently they love it! The range includes gilets, ponchos and hoodies, too. What are the big issues that outdoor brands are considering now? One of the big issues in the industry is still the question of DWR (durable water repellency) and finding nonPFAS versions that perform. Moving away from PFAS brings technical challenges. We need alternatives that deliver the protection people depend on, while keeping durability and repairability firmly in view. Waste recycling is also a big consideration.
