DuPont and Unifi Join Forces to Create Breakthrough Eco-Friendly Cold-Weather Apparel Insulation (10/11/17)
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.
REPREVE® is a high-quality fiber containing recycled materials, including plastic water bottles. Unifi’s proprietary process turns plastic bottles into certified fiber, which is then used in thousands of different fabrics and products available globally.
“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,” said Michael Saltzberg, global business director for Biomaterials at DuPont. “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 has a 45-year heritage as a textile solution provider driven by manufacturing innovation and creating differentiation for its customers. The company continues to build on its success by expanding its offering of branded recycled performance fibers that provide functional benefits, added comfort and aesthetic advantages. Unifi spent more than three years developing REPREVE with quality and performance as the primary goal – and recycled as the added benefit.
DuPont has a rich and deep history in the textile market, with inventions that include fibers such as nylon, Lycra®, Kevlar® and rayon – the world's first man-made fiber. More recently, in addition to Sorona®, DuPont’s biomaterials group has focused its innovations on creating other high-performing, sustainably sourced materials – the building blocks of products that consumers use every day.
“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,” said Ning Hongjun, president Unifi Asia Pacific. “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.”
DuPont’s industry-leading excellence in the biomaterials industry has received a number of accolades over the past year, including the Platts Global Energy “Breakthrough Solution of the Year” award for a partnership with ADM on a novel process to produce FDME from fructose; Frost & Sullivan’s award for 2017 European Company of the Year Award for bio-based materials; and, most recently, PLASTICS’ 2017 Innovation in Bioplastics Award.
