Phase Change Material and Thermoregulation Finishing
topic
Phase change material microencapsulation finishing incorporates PCM microcapsules containing paraffin wax or salt hydrate with defined phase transition temperatures of 28 to 34 degrees Celsius into textile substrates by padding or coating at 20 to 50 grams per square metre, with PCM absorbing thermal energy during heating and releasing it during cooling to buffer microclimate temperature changes and improve thermal comfort in performance sportswear and bedding.
Role
Provides active thermoregulation in textile products through PCM thermal energy storage that absorbs and releases heat at the human comfort temperature range, with PCM finishing enabling temperature buffering performance in sportswear, sleep textiles, and military protective clothing that passive insulation cannot provide, representing a premium functional finishing category with growing application in performance apparel and medical textile temperature management.
