Triexta (PTT)

(Polytrimethylene terephthalate, one of three types of polyester)
Triexta Carpet BCF Filament Fiber
TriextaTextile Filament Fiber

First U.S. Commercial Triacetate Fiber Production: 2003, Mohawk Industries

Current U.S. Triexta Fiber Producers: Mohawk Industries, Pharr Yarns

Federal Trade Commission Definition for Triexta Fiber: See definition for Triexta. (Complete FTC Fiber Rules here.)

Basic Principles of Triexta Fiber Production — Triexta is made by reacting PDO (1,3 propamediol) with either terephthalic acid or its methyl ester in the presence of an antimony catalyst. The reaction is carried out at high temperature and vacuum to achieve the high molecular weights need to form useful fibers by melt spinning. PDO, a product made from sustainable plant sources (corn glucose), contributes to Triexta’s eco-friendless.

Triexta Fiber Characteristics

  • More durable and resilient than conventional PET polyester
  • A matte luster comparable with nylon as opposed to the high  luster of PET polyester
  • Stain resistant
  • Greater softness comparable with nylon and PET polyester
  • Ultraviolet (UV) ray resistance
  • Elasticity (sag resistant)
  • Eco-friendliness with up to 37% of polymer derived from corn glucose rather than petroleum

Some Major Triexta Fiber Uses

  • Apparel
  • Home Furnishings: Carpets, rugs
  • Other Uses: Automotive mats, headliners, and upholstery
