The LYCRA Company, a globally recognised leader in crafting cutting-edge and sustainable fibre and technology solutions for the apparel and personal care sectors, unveiled its latest breakthrough—LYCRA® FiT400™ fibre designed specifically for knits.

This innovative EcoMade offering is a distinctive bicomponent fibre meticulously crafted to enhance the performance and comfort of knitted fabrics. It boasts a resilient, soft hand feel, minimal shrinkage, and exceptional uniformity. LYCRA® FiT400™ fibre is crafted from 60% recycled PET and 14.4% bio-derived resources, holding the prestigious GRS certification.

Featuring two distinct polyester polymers, this fibre creates a helical crimp that imparts permanent stretch and recovery properties to fabrics. Moreover, it enhances breathability, offers cooling comfort, and exhibits resistance to chlorine.

Beyond its performance attributes, LYCRA® FiT400™ fibre plays a pivotal role in advancing circularity—an imperative focus for The LYCRA Company. Rigorous tests, conducted under specific conditions, showcased the fibre's recyclability, affirming the technical feasibility of this process.

Steve Stewart, Chief Brand and Innovation Officer at The LYCRA Company, remarked, “We developed LYCRA® FiT400™ fibre to deliver sought-after performance benefits and elevate the softness of knit fabrics. This innovation aligns with the growing demand for more sustainable solutions, utilising recycled and bio-derived materials.”

The marketing strategy for LYCRA® FiT400™ fibre involves a trade-focused campaign—“It's Time for Better.” This campaign seeks to disrupt the activewear, athleisure, and swimwear sectors with a powerful message: consumers and the planet deserve superior products that offer enhanced functionality while reducing environmental impact.

Fabrics and garments powered by LYCRA® FiT400™ fibre are eligible for LYCRA® XTRA LIFE™ or COOLMAX® EcoMade brand hangtags, provided they meet stringent brand quality standards. Both these brands enjoy widespread consumer recognition on a global scale.
