Under Armour Inc., Baltimore, has launched a collection of men’s and women’s sports apparel
featuring coldblack®, a textile finishing technology developed through a cooperation between
Schoeller Technologies AG and Clariant International Ltd., both based in Switzerland.
The technology enables dark-colored fabrics to reflect rather than absorb the sun’s rays.
According to Schoeller and Clariant, textiles treated with coldblack reflect up to 80 percent of
heat rays and are guaranteed to offer a minimum ultraviolet protection factor of 30. The technology
is bluesign® approved and meets Oeko-Tex® Standard 100, class I-IV, requirements.
Schoeller and Clariant have developed 144 separate coldblack formulations for a range of
fabrics including knitted and woven 100-percent polyester and blends with elastane and polyamide in
a variety of colors. The fabrics also feature Switzerland-based Sanitized AG’s Sanitized®
antimicrobial fabric finish, which is distributed globally by Clariant.
