Abstract: In order to test and analyze the thermo-regulated performance of phase change textiles, cooling test and heating test were respectively designed, and the thermo-regulated performance of some phase change textiles was investigate by two methods (i.e. temperature change velocity and temperature change time ). The results show that the experimental results of cooling test and heating test have basically the same. The temperature change velocity method can get more comprehensive information, and the temperature change time method is relatively simple and fast. The test results of two methods are basically the same and can be chosen according to need. Compared with the normal textiles, the temperature change of phase change textiles during the process of cooling and heating is more slowly, so the thermo-regulated performance is better. The fabric specifications, such as thickness and tightness, have an effect on the thermo-regulated performance of phase change textiles to a certain extent.

Key words: phase change textile, thermo-regulating performance, temperature change velocity, temperature change time, fabric specification
