Effects of UV protective materials on the Wearer’s Thermal Comfort

In this research, the thermal comfort and thermophysiological reactionses of the subjects were analyzed and compared when the young men wore the 2 types of clothing combination which made of two types of men’s suit(general material, uv protective material) in a hot environments. The wear tests were performed in clomatic chamber controlled 27℃ air temperature. 50±10%RH and 0.5㎧ air movement. Five healthy young men participated in this experiment. The experiment schedule was planned 3 steps, that is, sedentary posture during 20 minutes - walking on treadmill by 2.5mph during 10 minutes - sedentary posture during 20 minutes. The results obtained is as follows: ① The mean temperature was lower in the case T1 than in the case T2(P＜.001). ② The oral temperature, sBP, HR, subjective sensations were not significant. ③ The microclimate temperature within clothing was lower in T1 than in T2(P＜.001). The microclimate humidity within clothing was lower in T2 than in T1(P＜.05 over).
