Covation Biomaterials is showcasing its two new bio-based products, Xatryx and Sorona Elasterell-p fibre, at the Functional Fabric Fair in New York City (July 7–9). 

Xatryx bioPTMEG is a bio-based polyether glycol made from corncobs, a renewable non-food agricultural by-product. PTMEG is a building block for elastane, and the bio version can be used as a drop-in replacement to the petroleum-derived version to reduce the fibre’s carbon footprint.
