The temperature-regulating fibres made by Coolcore LLC, a company based in Portsmouth, NH (USA) are the first product worldwide to be awarded the Hohenstein Quality Label “Innovative Technology – Cooling Power”.
With the award, the scientists at the internationally recognised and independent Hohenstein Institute in Bönnigheim, Germany, have confirmed the cooling effect of the textiles, which are entirely chemical-free and do not use latent heat storage or phase change materials (PCMs) that exploit a change in phase (solid-liquid) to absorb and store heat. The Coolcore textiles in fact exploit the body’s own sweat, or added moisture, to achieve cooling. The sophisticated design means that the evaporation rate is regulated and, as a result, the cooling effect of “evaporative cooling” is significantly higher than in conventional materials. These effects were investigated and evaluated scientifically using the WATson HeatLoss Tester measurement device developed at the Hohenstein Institute. The heat dissipated from the skin under very different ambient conditions, from tropical heat to cool temperatures, as well as the heat loss caused by high wind speeds can be quantified using the device. Using WATson, textiles can be tested during the development phase and optimised at an early stage. This is true in particular for items of clothing worn close to the skin with “cooling effect”. As a result, WATson is also ideally suited to guaranteeing compliance with quality standards in the course of ongoing production monitoring.
