DuPont Sorona and Sateri’s EcoCosy have together developed a new fabric called StretchCosy. The fabric uses a blend of Sorona, a partially plant-based fiber, and Sateri’s ultra-comfortable and near weightless EcoCosy fibers to achieve a soft material that is highly stretchable, shape-retaining and, most importantly, sustainably sourced.
StretchCosy combines the mechanical stretch of Sorona stretch fibers, which gives it excellent stretch and long-lasting, consistent recovery, with the soft, cotton-like breathability and smooth silk-like texture of EcoCosy for an unparalleled fabric that is high-performing and well-suited for fashion and sportswear.
Created in 2019, StretchCosy is a fabric breakthrough that made it possible for natural plant-based fibers to be more extensively used in various applications, e.g. t-shirts, shirting, bottoms, jackets, dresses, hoodies and underwear. Previously, cellulosic fibers were rarely found in sportswear, due to concerns such as pilling. The combination of Sorona and EcoCosy in StretchCosy has eliminated this concern, hinting at the future of activewear where performance combined with sustainability will be the norm.
