摘要：The heat storage and release capacities of phase change fabric loaded with phase change microcapsules were measured by differential scanning calorimetry (TADSCQ-2000). The melting peak splits into two sub-peaks at 20.83°C and 28.65°C, in which the heat enthalpy was 25.20 J/g, and the melting range was 16.5°C–36.8°C. The heat-conducting performance of the phase change fabric was tested using a YG (B) 606D face-plate thermometer, and the heat preservation coefficient improved to some extent from 1.05% to 32.2% than that of ordinary fabric. Contrast test was carried out for the shirt made of this fabric by the live test method. The results showed that the heat storage capacity of the phase change shirt was not enough to keep the human body maintaining a comfortable temperature for a long time on the occasions with a bigger temperature difference, thus requiring the need of other warm-keeping clothes. This phase change fabric exhibited good effects on maintaining the uniformity of body temperature and improving human comfort and could avoid low-temperature damages to four limbs in cold regions.
