WILMINGTON  [22.08.08] Invista introduced a new recycled versionof its Coolmax polyester fibre at the recent Outdoor Retailer showin Salt Lake City, where US legwear brands DeFeet and Injini bothlaunched socks with the new Coolmax EcoTech fibre.

Invista says this new Coolmax EcoTech fibre has been underdevelopment since May 2007 and is derived from post-consumerbottles made of polyethylene terephthalate (PET), which are thencleaned and converted into polymer flakes. These flakes are thenconverted into polymer chips, melted and extruded into polyesterfibre that can then be spun into yarn.

"Both Coolmax EcoTech and the current Coolmax fabrics aremade with the unique 4-channel cross section for high-performancepermanent moisture movement," said Invista. "Tests forabsorbency, wicking, hand, dyeability, and abrasion resistanceshowed Coolmax EcoTech fibres to be equivalent to existingCoolmax fabric standards."

Invista also says that the new recycled version of Coolmax alsogoes one step further, with demonstrated superior results overcurrent Coolmax fabrics when tested for whiteness and pilling.

Shane Cooper, the founder of technical sock brand DeFeet said,"We care deeply about the environment, and we are so excitedto see this great brand expanding its product line to includeCoolmax EcoTech fibre from recycled materials. What a phenomenaluse for plastic bottles!"
