NylaNova secures nylon-6 recycling supply deal
NylaNova has secured a prospective buyer for the recycled nylon feedstock it is developing from post-consumer waste.
The Evanston, Illinois-based chemical recycling company announced a partnership Wednesday with nylon-6 producer Nylene, which will source caprolactam recovered through NylaNova’s recycling process. Caprolactam is the chemical building block used to manufacture nylon-6, a material found in apparel, carpets and industrial products.
NylaNova’s technology, developed at Northwestern University, uses selective catalysts to break down nylon-6 waste into caprolactam that can be used to produce new nylon. The company says its process can handle mixed apparel, carpet and industrial scrap without pre-sorting, recovering more than 90 percent of the material.
Nylene operates an established nylon-6 recycling facility in Arnprior, Ontario, where it has used depolymerization technology since 1966. The agreement would give the manufacturer an additional source of recovered caprolactam for its nylon production.
“The real test of a recycling technology is whether a producer will buy the material and put it into production,” said Yosi Kratish, founder and chief technology officer of NylaNova. “Nylene knows exactly what quality their customers will accept. Meeting that standard is what we set out to do.”
NylaNova said it has demonstrated its process at the metric-ton scale using commercially available equipment. An independent third-party life cycle assessment found that its recovered caprolactam generated 95 percent fewer greenhouse gas emissions than conventional virgin production, according to the company. It also claims the material can compete with virgin caprolactam on price.
Norrøna, Uluu develop seaweed-based performance fiber
Seaweed could become a feedstock for the next generation of outdoor performance fabrics.
Norwegian outdoor apparel company Norrøna has partnered with Australian materials developer Uluu to explore fibers made from seaweed-derived polymers, to eventually incorporate the material into its products.
The companies have already produced an initial fiber combining Uluu’s seaweed-derived polyhydroxyalkanoate, or PHA, with polylactic acid, or PLA. Norrøna will work with one of its suppliers to evaluate the material’s durability and other performance characteristics before determining whether it can be used in outdoor apparel.
Uluu produces PHA through a fermentation process that converts sugars extracted from seaweed into polymers with plastic-like properties. The company says its material has passed TÜV biodegradability tests for marine and home composting environments. However, those results should not be taken as evidence that the newly developed blended fiber has the same properties.
“Building the next generation of outdoor materials requires brands to get involved before every question has been answered,” said Jørgen Jørgensen, CEO and fourth-generation owner of Norrøna. “For nearly a century, Norrøna has developed products around the demands of the outdoors. We are now bringing that experience upstream, helping shape the fiber itself around what outdoor performance requires.”
The partnership marks Uluu’s first development project in textiles. Its materials have previously been explored for applications in other industries, including packaging and automotive products.
Stadion brings London-made leather bag to new collection
London womenswear label Stadion is preparing to release the Orna Bag, a 450-pound ($606) leather handbag inspired by the plastic carrier bags found in neighborhood corner shops.
Part of the brand’s upcoming Apostasy of Dinner collection, the bag is handmade in London’s Seven Sisters neighborhood using leather sourced from Barcelona-based Inter Leather. Its interior features 100 percent organic cotton poplin sourced and custom-printed through London textile manufacturer Maake, while the hardware comes from UK suppliers.
Inter Leather sources hides from the food and livestock industry, according to Stadion. The brand describes the leather as a byproduct of meat production.
Founded in March 2024 by three school friends working out of a two-bedroom flat in Hackney, Stadion designs and manufactures its products locally. The self-funded company operates on a made-to-order model, producing pieces after customers purchase them rather than maintaining conventional inventory.
The Orna Bag will follow the same approach, with orders assembled in London and an estimated fulfillment window of two to four weeks. The bag is currently available to join a waitlist, although Stadion has not announced a release date.
Spinnova, Outlast eye temperature-regulating textiles
Finnish textile technology company Spinnova has signed a nonbinding letter of intent with Germany’s Outlast Technologies to explore using Spinnova fiber in temperature-regulating and insulating textiles.
The companies will investigate combining Spinnova’s mechanically produced cellulosic fiber with Outlast’s phase-change materials—which absorb, store and release heat—and its Aersulate aerogel insulation technology. The aim is to develop materials for performance apparel and other technical textile applications.
“We want Spinnova fiber to compete on performance as well as natural comfort,” said Mikko Lassila, Spinnova’s chief commercial officer. “Outlast brings established technologies for temperature regulation and insulation, and this collaboration gives us an opportunity to explore how they can be combined with our fiber. If successful, we believe this could open new applications for Spinnova fiber, broaden our addressable markets and support our long-term commercial scale-up strategy.”
Eco Age puts alternative performance materials on the runway
A windbreaker made entirely from wood-based lyocell, a wetsuit comprising natural rubber and garments designed to come apart for recycling were among the pieces presented at Eco Age’s inaugural “Fashion. For a Future.” runway at ISPO Amsterdam.
The showcase, held Nov. 4-5 and curated by the team behind the Green Carpet Fashion Awards, brought together outdoor brands, designers and materials developers to demonstrate alternatives to conventional synthetic performance apparel.
Participating companies included Armedangels, Finisterre, Craghoppers, Reima and The Mills Fabrica, which presented technologies from six materials innovators.
Armedangels showed a windbreaker with a ripstop shell woven entirely from Tencel Lyocell, without a synthetic membrane or intentionally added PFAS. The company says the fabric provides wind protection, breathability and light water repellency. The garment was named among Time’s Best Inventions of 2026.
“Outerwear has long relied on plastic and PFAS to keep the weather out,” said Julia Kirschner, impact and innovation director at Armedangels. “With this windbreaker, we wanted to challenge that default and choose nature over oil: a dense weave with wood-based Tencel Lyocell fibers that protects against wind and light rain.”
Other demonstrations included Dimpora’s waterproof membrane made with more than 60 percent biobased content derived from castor oil, Amphico’s approach to producing color through woven yarns rather than dye baths and Resortecs’ heat-responsive stitching, which allows selected garment seams to be separated for repair or recycling.
Sparxell presented plant-cellulose pigments that use structural color rather than conventional dyes, while Nuyarn demonstrated a performance wool yarn designed to provide stretch without added elastane. Synflux also showed a Goldwin collaboration incorporating Spiber’s Brewed Protein fiber and other biobased materials.
Finisterre contributed a jumper made with regenerative wool and a Yulex natural-rubber wetsuit. London College of Fashion students presented sportswear assembled from unsold merchandise, deadstock textiles and damaged secondhand outerwear.
Karl Mayer replaces hydraulic system in warping machine
Karl Mayer has replaced the hydraulic press-roll system in its Warpdirect 2.0 warping machine with an electric version designed to reduce maintenance. The German textile machinery manufacturer will demonstrate the upgrade at ITMA Asia 2026 alongside equipment for controlling yarn tension and reducing sizing consumption.
The company will demonstrate its Warpdirect 2.0 direct warping machine alongside the HSB Size Box, a component of its Prosize sizing system.
Warpdirect 2.0, introduced last year, can operate at warping speeds of up to 1,200 meters per minute, according to Karl Mayer. The latest version replaces a hydraulic press-roll mechanism with an electric system designed to reduce maintenance while maintaining yarn alignment and beam quality.
The machine can be configured with different tensioning systems for staple fibers, denim yarns, silk and technical textiles. Karl Mayer will also demonstrate upgrades to its optical yarn monitoring and tension-control technologies.
“Our machines produce warp beams of the highest quality with high process efficiency,” said Enzo Paoli, president of Karl Mayer’s Warp Preparation Business Unit. “This offers particular advantages to textile manufacturers who are focused on generating real added value in a highly competitive market.”
The company’s HSB Size Box is designed to reduce the amount of sizing chemicals applied to yarns before weaving. Karl Mayer says the system can cut sizing consumption by up to 10 percent, likely reducing material costs and the resources required to remove sizing agents during subsequent textile processing.
Ororo introduces Bluetooth-controlled heated apparel
Heated apparel company Ororo is adding Bluetooth controls to its clothing, allowing wearers to adjust garment temperatures through a smartphone rather than relying exclusively on physical buttons.
The Las Vegas-based company introduced its first Bluetooth-enabled heated liner vest on Nov. 3, along with a mobile app for iOS and Android.
The unisex vest incorporates five heating zones positioned across the abdomen, lower back and shoulders. Its quilted construction includes a wind- and water-resistant exterior, adjustable waist closure and external battery pockets. Through the app, customers can adjust heat settings, monitor battery levels, set timers and review garment usage. An Eco Mode is intended to extend battery runtime, while low-battery alerts notify wearers when charging is needed.
“Our app gives customers more control over their warmth, from customizable heat levels and using Eco Mode to extend battery runtime to setting timers and tracking usage,” said Ororo CEO Mark Hu.
