LYCRA® T400® TECHNOLOGY

T400®

Offers the stretch and recovery of spandex in a polyester fiber

Why choose LYCRA® T400® technology?

The challenge:    

For designers, garment makers and brands that have end uses requiring spandex-free stretch, choose the original elasterell-p bicomponent polyester fiber from The LYCRA Company.

The solution:                       

LYCRA® T400® technology is a great choice for stretch apparel that keeps it shape and delivers excellent aesthetics. An inherently elastic elastomultiester polyester fiber, this technology can replace textured yarn in just about any stretch textile used for clothing. This fiber’s unique structure also provides moisture-wicking properties, which makes it a qualifying fiber for COOLMAX® technology branding.
