The new DynaPelTM zipper uses GTT EMPEL® technology to eliminate the need for a PU film
Atlanta, GA (Nov 16, 2023) - YKK announces the release of its new DynaPelTM water-repellant zipper featuring GTT EMPEL® technology. Designed to be compatible with garment recycling systems, DynaPelTM uses EMPEL® technology instead of the standard PU film to achieve its water repellency. The lack of a PU film helps remove one of the barriers of textile-to-textile recycling of performance apparel by eliminating the urethane material, which presents challenges to garment recycling processes.1
“DynaPelTM is a valuable addition to our growing collection of fasteners designed for circular systems,” said Terry Tsukumo, Vice President, Product Strategy Division, Global Sales Headquarters, YKK Corporation. “By employing EMPEL® technology, we can achieve the robust water protection expected from YKK® products while eliminating the challenges that PU poses to recycling systems.”
Conventional chemical and mechanical garment recycling systems cannot process the polyurethane film commonly used on water-repellent zippers, necessitating the removal of zippers from garments before recycling. This additional processing step often deters recyclers from accepting garments with PU zippers, resulting in unnecessary waste.
EMPEL® technology uses advanced green chemistry devoid of PFAS and a specialized manufacturing process that allows the chemistry to penetrate the yarn and encapsulate it with a water-repellent layer through molecular cross-linking. The molecular cross-linking creates an extremely durable layer that is highly resistant to abrasion and invisible to the eye.
“DynaPelTM represents a new generation of sustainable, high-performance water-repellant zippers,” stated Tsukumo. “It is the future of water protection for zippers.”
DynaPelTM zippers were showcased at the Outdoor Retailer trade show in Salt Lake City and will be featured at the ISPO trade fair in Munich, Germany. Notably, DynaPelTM has been nominated for the Best New Product Award in the ISPO Textrends competition held at ISPO.
