The U.S. Federal Trade Commission (FTC) has ruled that fibers made from PTT1, the latest polymer innovation from DuPont, offer a unique combination of attributes which merit a new generic name, triexta. PTT polymer sold for the manufacture of triexta for apparel and flooring applications is sold under the DuPont™ Sorona® brand. Triexta fibers are informed to provide a unique combination of exceptional durability and stain resistance compared to previously available fibers. The FTC based its decision on testing of residential carpets, which demonstrated that triexta significantly outperforms carpets made from polyester in resilience and durability. DuPont also discovered and commercialized well-known high performance fibers such as nylon, rayon, DuPont™ Kevlar® and Nomex ®.
Fabrics made with Sorona® are claimed to offer exceptional durability and softness; built-in permanent stain and ultraviolet (UV) ray resistance and outstanding elasticity while resisting stretch and sag over time. As per the company, Sorona® fabrics provide a carbon dioxide reduction of 30% while the Sorona® manufacturing process reduces greenhouse gas emissions by 63%, compared to conventional nylon made from petroleum. Fibers made from Sorona® are sold into a variety of markets including floorcovering, apparel and upholstery. The company recently completed the construction and start up of the new capacity expansion at Kinston, North Carolina.
