Staying cooler and sweating less means being more comfortable and increased activity levels and that is exactly what coldblack technology from Schoeller provides, as a test of the EMPA in St. Gallen shows. In their laboratory, the wearing comfort of coldblack under increased influence of heat was investigated.
Three shirts (beige, coldblack-black, standard-black - see chart) were placed onto the sweating torso (see picture) and were submitted to simulated sweating activity.
The results speak for themselves: the torso – which is comparable with a humanbeing – with a coldblack black shirt, compared to one with the untreated black shirt, produced only about half as much sweat, in compensation for the same increase in “skin” temperature.
A loss of fluid equal to 2% of body weight through perspiration reduces body efficiency by up to 20% and vital minerals are lost. As a result, endurance and concentration can decrease. Therefore, wearing coldblack means staying in the game longer.
coldblack: Sun Reflector – UV Protector coldblack, the textile finish developed by Schoeller Technologies AG and Clariant International Ltd., provides dual sun protection: dark colors heat up less in sunlight and it also offers reliable protection against UV radiation. coldblack was developed in Switzerland in accordance to the criteria of the bluesign standard, the world's most stringent production standard for Environment, Health and Safety specifications (EHS) and was the winner of the Popular Science Best of What's New award in 2008.
In addition to the collections of Schoeller Textil AG, coldblack is applied by other textile producers, such as Burlington Worldwide; Christian Eschler AG; Taffeta Formosa Co. Ltd. and Miti Spa.
