Yarn maker Unifi Inc is launching a nylon 6,6 version of its Repreve branded yarn, which is made solely from recycled materials.

Unif has also worked in partnership with Burlington Worldwide, a division of International Textile Group, and United Knitting to develop new woven and knit fabrics using the new yarn.

ITG will feature Repreve nylon under the Generations Collection, targeting technical sportswear; and United Knitting will introduce Repreve nylon in a series of new eco-friendly knit fabrics for activewear.

The production of Repreve offsets the need to produce virgin polyester and nylon from petroleum-based resources, with its current annual production estimated to conserve the equivalent of 6m gallons of gasoline.

Repreve nylon will be launched at the Outdoor Retailer Summer Market 2008 trade show, which takes place from 8-11 August at the Salt Palace in Salt Lake City, Utah.
