The Lycra Company/Suedwolle: Sustainable dyeing process for wool blends

摘要

The provider of fiber and technology solutions The Lycra Company, Wilmington, DE/USA, and the manufacturer of worsted products Suedwolle Group, Nuremberg/Germany, have partnered to bring GRS certified cationic dyeable Coolmax EcoMade long staple yams into the wool market. Among the existing types of recycled polyester that can be blended with wool, Coolmax EcoMade technology distinguishes itself by its cationic dyeability. This property considerably facilitates the dyeing process in piece or cone dyeing and enables a gentler dyeing process at lower temperatures using less energy. This not only helps to ensure that the touch and handle of the wool are not impacted, but is also a positive development for sustainability within this market. Furthermore, generally, a cationic dye process tends to deliver better color and color fastness.
