Covation Biomaterials LLC (CovationBio) is presenting its two latest bio-based innovations, Xatryx and Sorona elasterell-p fiber, at the Functional Fabric Fair being held in New York City.

One of the company’s latest innovations is Xatryx bioPTMEG, a second-generation bio-based polyether glycol produced from corncobs, a renewable and non-food agricultural by-product. It is designed as a direct replacement for conventional petroleum-based polytetramethylene ether glycol (PTMEG). It allows manufacturers to switch to the bio-based material without making changes to their existing production processes. The material is suitable for performance apparel applications that use spandex, polyurethanes, and thermoplastic elastomers.

CovationBio is also showcasing Sorona elasterell-p fiber, the first U.S.-made bicomponent stretch fiber produced with 37% plant-based Sorona polymer. The fiber provides long-lasting stretch and shape retention without the need for elastane. Sorona elasterell-p fiber is designed for a wide range of apparel applications, including activewear, athleisure, workwear, uniforms, and other garments that require durable stretch and lasting comfort.

“Functional Fabric Fair brings together the designers and developers shaping the future of performance apparel, and these are the people we developed these innovations for,” said Steven Ackerman, CEO of CovationBio. “Together, Xatryx and Sorona elasterell-p fiber help our partners improve product performance, simplify adoption, and reduce their environmental impact.”
