Abstract

In order to get a stable heat preserved property of temperature control textile, the sandwich structure of thermochromic phase change nanofibers/ woven composite materials was made by electrospinning, weaving and simple suture. In this material, the thermochromic powder acted as a temperature indicator, lauric acid is selected as phase change material. The morphologies and heat preserved property were characterized by SEM, a digital single lens camera and an increase-decreased temperature system test, respectively. The results showed that such composite materials exhibited an obviously heat preserved property; it took 17mins to decrease the temperature from 50 °C to 30 °C, which was 4 mins longer than the weaves.
