World’s largest manufacturer of spandex, Hyosung TNC and a leading global producer of regenerated cellulosic fibers, the Lenzing Group, have joined forces to launch a new yoga fabric collection.
This collaboration unites a shared vision for sustainable innovation, blending certified low-impact fibers, performance engineered for modern movement, and inspiration drawn directly from nature.
The new collection will debut at the Functional Fabric Fair (FFF) in Portland, Oregon, from November 12-13. Both companies will showcase a yoga-inspired concept garment range designed by Hyosung TNC's Fashion Design Center. The fabrics are made using various blends of Lenzing’s Tencel and Lenzing Ecovero with Refibra technology alongside Hyosung TNC’s certified regen Bio Spandex (partially made with renewable resources), 100 per cent recycled regen Spandex, and creora color+ Spandex.
The collection was developed with technical expertise from Pacific Textiles, a premium circular knit partner specializing in sustainable fabric production. This partnership successfully optimized the fabric structure and heat-setting process to ensure consistent stretch and a natural, soft-hand feel. The joint effort maintains the signature smoothness of Tencel fibers while achieving excellent stretch and recovery, resulting in a premium yoga and athleisure fabric that perfectly balances sustainability and performance.
According to Nicole Schram, Head-Global Technical Development, Lenzing, the company’s. partnership with Hyosung TNC beautifully illustrates this idea of collaborative cooperation, exemplifying how material innovation and cross-industry collaboration can accelerate the transition to bio-based, traceable, and scalable alternatives—delivering on both technical excellence and environmental responsibility.
Simon Whitmarsh-Knight adds, the regen Bio Spandex uniquely pairs with Lenzing’s luxurious wood-based fibers to create this perfect sustainable solution. Collaborative partnerships are essential as the textile industry strives for innovative and high-performance solutions across the value chain to meet brand and consumer sustainability objectives.”
Hyosung TNC will highlight its expanded regen Bio Spandex range, detailing the transition of the fiber's renewable feedstock from corn to sugarcane. This change enables lower carbon emissions without compromising performance. To ensure full traceability and transparency, the company has joined the VIVE Sustainable Supply Program.
Hyosung TNC will also showcase other innovative performance fibers at FFF, including creora Conadu Polyester and creora EasyFlex Spandex.
