Celanese and Under Armour develop new recyclable fiber for performance stretch fabrics

Celanese and Under Armour collaborated to develop a new fiber – NEOLAST, for performance stretch fabrics. This innovative material will offer the apparel industry a high-performing alternative to elastane, an elastic fiber that gives apparel stretch, also known as spandex.

Celanese and Under Armour jointly develop NEOLAST fiber for performance stretch fabrics.

NEOLAST fibers are produced using a proprietary solvent-free melt-extrusion process, which eliminates potentially hazardous chemicals typically used to create stretch fabrics made with elastane.

Solvent-free melt-extrusion process for producing the new fibers.

The fibers also deliver increased production precision, allowing spinners to dial power-stretch levels up or down and engineer fibers to meet a broader array of fabric specifications.

NEOLAST fibers feature outstanding stretch, durability and comfort. Using recyclable elastoester polymers, the fibers also address sustainability challenges associated with elastane, including recyclability.

As end users transition to a more circular economy, Celanese and Under Armour are also exploring the potential of the fibers to improve the compatibility of stretch fabrics with future recycling systems and infrastructure.
