The nonwoven fabric is often used as the disposable product. The purpose of this study is to evaluate the effects of two kinds underwear with different textiles (nonwoven; A or knitted; B). Thermophysiological responses were compared with two kinds of underwear in cold condition (C: 25℃60%RH→15℃60-75%RH) and hot condition (H: 30℃60%RH). Five and six young female adults participated on each condition, respectively. After the subjects rested for 15min in a chair, they worked for 15min exercise on a bicycle ergometer (70W) followed by 60min and 50min rest under each condition. Main results were summarized as follows: 1) Rectal temperature, mean skin temperature and clothing microclimate temperature (chest) after work in cold condition were kept significantly higher in A than in B. 2) Clothing microclimate humidity was significantly lower in hot condition in A than in B. 3) There were not any differences for skin temperatures, heart rate and subjective sensations between A and B. Thus, it was concluded that nonwoven underwear seemed to be more effective in keeping core temperature constant, mean skin temperature and clothing microclimate comfortable in cold and keeping clothing microclimate humidity appropriate in hot environnments.
