Abstract
In order to study the influence of underwear on human thermal and moisture comfort in different sports conditions, the objective and subjective evaluation of underwear (including undershirt and underpants) made of three kinds of fabrics were carried out, and the underwear comfort model was established by CFD, and the application prospect of CFD technology in the field of clothing comfort research was prospected. The results show that the underwear combination of different fabrics has certain influence on the thermal and moisture comfort of human body, and the thermal and moisture of fabric of composite fiber is better than that of fabric of single fiber, the temperature and humidity of chest, back, hip, and thighs of the human body in different motion states change, and the temperature and humidity of the chest and back change greatly, and CFD can accurately predict human skin temperature.
