DuPont Biomaterials’ Sorona fiber has unique stretch applications. Garments today no longer need spandex for athletic movement. Sorona fibers are a replacement for spandex (or elastane), achieving long-lasting, mechanical stretch and recovery with a better-for-the-planet profile. Sorona fibers are bio-based, use lower dying temperatures and are recyclable unlike bamboo or rayon. Sorona can be used as a standalone elastane alternative – one that does not breakdown over time with heat, washing, UV rays, or chlorine exposure and is recyclable in any normal polyester recycling stream. With mechanical stretch and recyclability at its core, the Sorona brand is offering innovative solutions to this industry-wide challenge. Whether incorporated into yoga tights or a luxury gown, Sorona fiber’s versatility and mechanical, long-lasting stretch make it an excellent replacement for spandex.

Companies which are into knit fabrics, denim fabrics or woven fabrics utilise textured yarns to provide the fabrics optimal stretch performance. These fibers are 37 per cent bio-based and can be used in a variety of applications, including seamless knitted T-shirts and other apparel as well as knitted footwear. Australian brand Think Love Live’s Serotonin shorts and Endorphin tights are made from 70 per cent lyocell and 30 per cent Sorona fibers for optimal comfort and stretch.
