The U.S. Federal Trade Commission (FTC) has determined that fibers made from polytrimethylene teraphthalate (PTT), 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 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.

“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 Ranieri, vice president and general manager, DuPont BioMaterials Group.  “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 fibers industry in the last 20 years.”
