Workwear brands can now adopt coldblack

26/05/2011
Schoeller Technologies has announced the adoption of the company’s coldblack sun protection technology in heavy-duty workwear. It presented a joint solution with Swiss textile finishing firm Bezema at the 2011 Techtextil exhibition in Frankfurt in May.

Launched in 2009, coldblack quickly became established in the sports and outdoor markets and attracted the interest of manufacturers of workwear, especially those offering clothing for outdoor workers. Until now, however, the textile finish that applied coldblack was not suitable for industrial laundering. “Time and again we have had enquiries from the workwear area but the finish was not suitable for rental garments,” said Hans U. Kohn, chief operating officer of Schoeller Technologies, in the build-up to Techtextil. “This meant that important markets remained closed to us.”

The solution has been to use vat dyes. Vat-dyed fabrics are suited for industrial and rental garments because they offer high levels of colour-fastness; they neither run nor discolour other fabrics during laundering, not even in a 95-degree hot wash. Vat dyes are an area of particular expertise of Bezema’s, which is why this company became involved in the launch of coldblack for workwear. The company’s chief executive, Beda Elmiger, said a vat-dye application of coldblack had created “a product with extremely high performance”.
