Phase Change Materials (PCM) play an important role in modern textiles. The Hohenstein Institute has investigated how effective PCM products are with the help of the WATson Heat Loss Tester. Whether for sports or outdoor wear, personal protective clothing or for bed linen: PCM textiles are becoming increasingly popular. But the greater
The number of applications, the greater the demands made on textiles containing PCM. How is the effect they promise perceived by the wearer of such textiles? Until now there has not been any clothing-related physiological method of measuring this. Physical measurements were only able to indicate changes in temperature.
A research project currently underway at the Hohenstein Institute has developed the first measuring method that allows the effect and efficacy of PCM in textiles to be tested without costly wearer trials. This new test method has not only made it more simple to demonstrate the functionality of textiles but also to offer proof of quality. This research project involved testing PCM-containing products from the market and coating textile samples with varying quantities of PCM.
