Puma has collaborated with Central Saint Martins, the London-based arts and design college, on a new collection that focuses on sustainable technologies in textile manufacturing. The Puma X CSM collection comprises a range of footwear, apparel and accessories that use environmental-friendly dyeing technologies such as “Dope Dye” and digital printing. These technologies are said to have resulted in a reduction in water consumption of up to 17.4 percent, depending on the product. Dope dyeing uses less chemicals, energy and water as compared to conventional wet processing, since one step in the dyeing process is eliminated. Digital printing is also said to help reduce waste and chemicals. The collection uses cotton from the Better Cotton Initiative, a non-profit that promotes better standards in cotton farming and practices.
