DuPont and Unifi Join Forces to Create Breakthrough Eco-Friendly Cold-Weather Apparel Insulation

The combination of Sorona® and REPREVE® provides brands the opportunity to use a high-performance, durable insulation that dries quickly and keeps its shape even after washing.

DuPont Industrial Biosciences (DuPont) announced today a collaboration with Unifi, Inc. to create high-performance, renewably sourced garment insulation, offering leading apparel brands a new sustainable choice for cold-weather products. This partnership brings together two leaders in the materials space with unique product offerings, combining DuPont™ Sorona® polymer and Unifi REPREVE® to produce cold-weather apparel insulation that is uniquely soft and extremely durable, with excellent shape retention.

DuPont™ Sorona® is made from 37 percent renewable plant-based ingredients, using 30 percent less energy with 63 percent fewer greenhouse gas (GHG) emissions as compared to Nylon 6. The exceptional softness, inherent stain resistance and uncompromising durability of Sorona® offers customers in a wide range of industries a more sustainable, high-performance materials option. The polymer has been used in everything from carpeting to Indian sarees.
