高温环境中服装材质对人体运动生理心理的影响

Effects of Clothing Material on the Motional Physiological and Psychological Comfort Under High Temperature

高温环境中,人体服装要反复经历吸湿(汗)——放湿——干燥过程.通过在高温环境中穿着不同材质服装的人体运动实验,测得了人体皮肤温度、微气候区的温湿度、人体代谢量、汗液蒸发率以及主观感觉值等诸多参数,并对此进行了分析.研究表明:与人体高温静立状态下服装的吸湿性对服装热湿舒适性具有显著影响不同,在高温运动状态下由于运动造成空气对流效应,织物的厚度和透气性对服装的热湿舒适性具有显著影响,此时应选择轻薄和透气性良好的服装.

Under high environmental temperature, garments will be subject to repeated cycles of moisture and sweat absorption, desorption, and drying. In this paper, the skin temperature, tem- perature and humidity within the microclimate between body and garment, body metabolic level, sweat evaporation rate and subjective feeling values were measured and analyzed, through experi- ments on humans wearing garments made of different clothing materials under high temperature. The results show that thickness and air permeability of the fabric have significant influences on heat and moisture comfort of the garment under motion state, because convection effect caused by the move- ment of air, which is obviously different from those under still state, where hygroseopieity of the gar- ment is dominant for heat and moisture comfort. Therefore, under motion state and high environmen- tal temperature, garments with light weight and good air permeability should be preferably selected.
