LYCRA® T400® fiber is an all-in-one polyester-based fiber solution for performance fabrics. Also available as LYCRA® T400® EcoMade fiber, made with recycled PET and plant-based materials.
This exceptional bicomponent fiber solves a wide range of consumer problems: It's quick-drying, moisture-wicking, comfortable, and easy care. Plus, it's extremely durable, resisting damage and providing long-lasting performance benefits in soft, smooth fabrics that retain their shape for a lasting fit. It withstands industrial laundering, too, proving itself essential in the workwear segment.
