Unitin’s sustainability efforts, making yarn from waste

Spain’s Unitin is a leading supplier of indigo dyed yarns and fabrics. The company has always been concerned to work with the most advanced standards, both on the technical as well as the environmental fronts, and is now giving one more step toward a zero waste policy.

Producing indigo warps and wefts in a continuous and modern machinery generates a certain quantity of leftovers. Approximately three to five per cent of total production is not usable and has to be rejected.

Now Unitin has the technology to reuse all indigo cotton leftovers and make yarn out of them. In order to assure that the yarn will have the right strength to be used in any textile application, either knits or wovens, the indigo cotton leftovers are mixed with recycled polyester fibers. Unitin also offers a few sets of sustainable fabrics made with the new recycled yarns with sustainable Tencel yarns. The use of the already indigo-dyed cotton eliminates the need to dye the yarn, saving water and energy. Also the final garment wash will demand less water and chemicals. All production is certified under the Global Recycled Standard.

Unitin is a part of Industrias Morera, a textile group specializing in dyeing and finishing on piece and yarn. It has been in the textile business since 1924, and is composed of four departments: yarn die, piece dye, upholstery and denim.
