What Is T-400?

T-400 is a high-performance elastic fiber developed by DuPont, designed to offer stretch and recovery without the use of traditional spandex. It’s a bicomponent fiber made from two different polymers—polyester (PET) and polytrimethylene terephthalate (PTT)—which are extruded side-by-side. This unique structure gives T-400 its natural elasticity and excellent dimensional stability.

 Key Features of T-400

• Stretch & Recovery: Provides comfortable stretch and excellent shape retention without the drawbacks of spandex (like yellowing or degradation over time).

• Wrinkle Resistance: Maintains a smooth appearance even after repeated wear and washing.

• Moisture Management: Offers quick-drying and moisture-wicking properties for enhanced comfort.

• Colorfastness: Superior dyeability and resistance to fading compared to spandex blends.

• Durability: Withstands repeated laundering and wear, making it ideal for long-lasting garments.
