DuPont, Unifi collaborate for Eco-Friendly Apparel Insulation using Plant Material and Plastic Bottle
DuPont Industrial Biosciences (DuPont) collaborates with Unifi, Inc. to create high-performance, renewably sourced garment insulation, offering leading apparel brands a new sustainable choice for cold-weather products. DuPont Soronapolymer and Unifi REPREVE, leaders in the materials space, are used to produce cold-weather apparel insulation that is uniquely soft and extremely durable, with excellent shape retention.
DuPont Sorona, made from 37 percent renewable plant-based ingredients, when compared to Nylon 6, uses 30 percent less energy with 63 percent fewer greenhouse gas (GHG) emissions. Sorona has exceptional softness, stain free and uncompromising durability qualities. Everything from carpeting to Indian sarees uses this polymer.
Unifi’s proprietary process recycles plastic bottles into certified fiber REPREVE, which is then used in thousands of different fabrics and products available globally.
Michael Saltzberg, global business director for Biomaterials at DuPont, said, “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. The new insulation’s unique warmth and durability will bring customers streamlined outerwear, made from eco-friendly materials, while maintaining maximum warmth and breathability”.
Unifi continues to build on its success by expanding its offering of branded recycled performance fibers that offer functional benefits, added comfort, and aesthetic advantages.
DuPont is known for inventions that include fibers such as nylon, Lycra, Kevlar, and rayon — the world’s first man-made fiber. In addition to Sorona, DuPont’s biomaterials group has focused its innovations on creating other high-performing, sustainably sourced materials.
Ning Hongjun, president Unifi Asia Pacific, commented, “This collaboration will give customers the freedom to choose a new type of garment insulation — one that is better for the environment without compromising performance. With our expertise in recycled polyester staple fiber and DuPont Industrial Biosciences’ industry-leading Sorona, we look forward to seeing this breakthrough technology be widely adopted by leading brands.”
