Coolcore LLC, a company based in Portsmouth, NH (USA) has been awarded the Hohenstein Quality Label ‘Innovative Technology - Cooling Power’ for its temperature regulating fibres. The Coolcore textiles 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 Heat Loss 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.
With the award, the scientists at the internationally recognized 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 Hohenstein scientists are therefore able to look at the textiles' different fields of application and the associated climatic conditions in a very flexible way in their investigations. As a result, WATson is also ideally suited to guaranteeing compliance with quality standards in the course of ongoing production monitoring.
