‘발열내복’이라 광고되는 시판 기능성 보온내복의 써멀 마네킹과 인체 착용 실험을 통한 체온조절 성능 평가 (Evaluation of Thermoregulatory Properties of Thermal Underwear Named as ‘Heating Underwear’ using Thermal Manikin and Human Performance Test)

초록

This study evaluated the thermoregulatory properties of functional thermal underwear (‘heating underwear’) in markets using a thermal manikin and human wear trials. One ordinary thermal underwear (ORD) and two functional thermal underwear (HEAT1 and HEAT2; manufactured goods, HEAT1: moisture absorbing heat release mechanism, HEAT2: heat storage, release mechanism) were chosen. Thermo-physiological and subjective responses were evaluated at an air temperature of 5.0±0.5oC and air humidity of 30±5%RH with five male subjects (21.6±1.3yr in age, 178.0±5.9cm in height, 68.2±5.9kg in body mass). Experimental conditions consisted of four ensembles that included winter clothes (Control: no underwear, ORD, HEAT1, HEAT2). Water-vapor resistance was greater in fabric of HEAT1 than others. The results were: 1) Total thermal insulation (IT) using a thermal manikin were not greater for HEAT1 (0.860clo) and HEAT 2 (0.873clo) than for ORD (0.886clo). 2) There were no significant differences in rectal temperature, mean skin temperature, heart rate and total body mass loss between the four conditions. Microclimate clothing temperature on the back was greater for ORD than for HEAT1 and HEAT2. Subjects felt more comfortable with HEAT1 than for others at rest. HEAT2 was higher in microclimate humidity when compared to other conditions. The results suggest that thermoregulatory properties of ‘heating underwear’ in market did not differ from those of ordinary thermal underwear in terms of total thermal insulation and thermoregulatory responses in a cold environment.
