Triexta Fiber Classification is Generic in Name Only
Fibers made from PTT, the innovative DuPont polymer, are classified under the generic name triexta by the U.S. Federal Trade Commission (FTC). The PTT polymer, also known as poly (trimethylene teraphthalate), is sold under the DuPont™ Sorona® brand to a variety of markets including carpet, apparel and automotive flooring.
What makes Sorona® different from other fibers is that it uniquely combines many benefits in a single product. It offers exceptional durability and stain resistance and the ability to blend with and enhance the performance of other natural and man-made fibers. This combination of performance benefits was so unique that in 2009, the FTC granted a new fiber generic – triexta – for homo fibers made from PTT.
Fibers made from triexta are used in carpet, apparel and automotive flooring. Apparel fabrics made with Sorona® offer durability and softness, ultraviolet (UV) ray resistance and outstanding elasticity, while resisting sag over time. Apparel manufacturers, including Izod, Timberland, Calvin Klein Golf and Spun Bamboo, have incorporated Sorona® fibers into their product lines. Automotive manufacturers are using Sorona® in mats, headliners and upholstery for auto interiors.
But for the FTC, it was the outstanding performance of Sorona® in floor covering that really stood out. The FTC based its generic name decision on test results of residential carpets, which demonstrated that triexta significantly outperforms carpets made from polyester in resilience and durability. Triexta fibers provide a unique combination of exceptional durability and stain resistance compared to other fibers.
"The designation of the generic triexta is significant and further validates the importance of the superior performance and distinct attributes offered by Sorona®," said John P. Ranieri, vice president, DuPont Industrial Biosciences. "In addition to the performance advantages recognized by the FTC, Sorona® is made in part from renewably sourced ingredients. It is the most transformative polymer to be introduced into the fiber industry in the last 20 years."
"Our dealers told us that the current generic was misleading to consumers, and that they found it difficult to clearly communicate the benefits of this different and superior product when it fell into the same category as traditional polyester products," said Jeff Lorberbaum, chairman and chief executive officer, Mohawk Industries. "We are thrilled with the FTC’s ruling. Carpets with triexta offer a true performance advantage to customers."
Benjamin Davies, who works for floor covering dealer Special Effects/Garmar in North Carolina adds: "We have found that the PTT products have had a superior history as far as resilience and stain resistance as well as much softer hand feel."
In the United States, the triexta classification for Sorona® continues the long tradition of DuPont innovation in the polymer and fiber industry. DuPont has discovered and commercialized revolutionary fibers including nylon, rayon, DuPont™ Kevlar® and Nomex®.
