A new sustainable program by Unitin is turning waste into yarn.

The Spanish dye and finishing company announced Monday the launch of recycled indigo yarns. The new implementation has been set up to reuse all the indigo cotton leftovers modern machinery generates while producing continuous indigo warps and wefts and make yarn out of them. Unitin blends the “leftovers” with recycled polyester to ensure the yarn will have the correct strength to be used in knit and woven applications.

As a first step, the company introduces count Ne 7/1 Pes/Cot 50/50 in two shades, dark and light. Twisted yarns are also offered. A few sets of sustainable fabrics are made with the new recycled yarns with sustainable Tencel yarns. As this production is made of Unitin leftovers, only a limited stock will be available.

Unitin always been concerned to work with the most advanced standard both on the social as well as the environmental responsibility, and is now giving one more step toward a zero-waste policy.

Approximately 3-5 percent of total indigo warp and weft production is not usable and has to be rejected, Unitin reported. The use of the already indigo-dyed cotton eliminates the need to dye the yarn, saving water and energy, while the final garment wash will demand less water and chemicals. All production is certified under the Global Recycled Standard.
