Schoeller’s coldblack technology has been specifically optimised for use on knitted and woven fabrics so brands can now expand their product application uses, with the support from Südwolle Group, a leading manufacturer of high quality yarns.

Wool is well known for its various property benefits, including insulation, natural antibacterial protection, odour control, light weight and nearly wrinkle free composition. Not only in the winter time, but also in summer particularly merino wool, a special high-quality type of wool, regulates moisture balance and thus the body temperature. The fibres can absorb a great deal of moisture or sweat and transport it away from the body. Warm ambient air quickly dries the material and causes a cooling evaporation, which makes it very comfortable to wear merino apparel in the summer time.

coldblack technology from Schoeller aims to support the natural properties of wool because it reliably reduces heat build-up when exposed to the sun. Together with the help of Südwolle Group, the finish has been optimised specifically for the use in merino apparel. The yarn manufacturer chooses coldblack for a variety of uses, especially for knitting and weaving yarns for sports and outdoor apparel and develops such products individually according to its customers’ requirements.

“coldblack is part of our product range for the summer time, which we will be presenting at OutDoor show in Friedrichshafen,” said Stéphane Thouvay, Managing Director Product Management & Innovation at Südwolle Group.

“The technology reduces not only heat build-up, but also enhances the natural UV protection of wool without affecting the look and feel of the fabric. Therefore, coldblack perfectly fits into our yarn selection for sports and outdoor apparel, for example in our collection Yarn in Motion. For end consumers garments made of coldblack yarns can optionally be labelled with hangtags.”

When used in high-quality woolen fabrics, coldblack has already proven its performance and is being used by renowned brands in various collections of men’s suits, according to the manufacturer. Since 2008, the technology has been licensed by more than 200 brands, in sports particularly in the field of cycling, triathlon and golf. All components of the finish are bluesign approved.
