This kind of transmit will lead the body temperature rise and result in skin burning. This study focused on the relationship between clothing surface temperature to thermal protective performance and body temperature and their influential factors based on flame manikin and thermal energy storage theory. Then, the surface temperature of clothing and body were analyzed and an empirical model between clothing and body temperature to time was explored and optimized. The skin burning area percentage was used to represent the thermal protective performance of the clothing, the correlation analysis between the percentage to clothing surface temperature, body temperature, and air gap was tested by using SPSS. The results showed the thermal protective performance had a negative relationship with clothing and body surface temperature. The relationship between clothing surface and body temperature showed that the clothing surface temperature had a obvious correlation to the initial and maximum temperature of body. But coefficient between clothing surface temperature and the maximum body temperature was bigger, this meant that the clothing surface temperature had a great influence to the change of body temperature after fire exposure. Different factors of clothing, fabrics, body, and setting situation had been controlled to test their influence to clothing surface temperature. The result showed that the air gap made an important role in the testing, the thinner the air gap was, the higher the clothing surface temperature was, and this tren
