의복의 쾌적감에 영향을 미치는 인자로는 크게 미세공간의 온도, 습도, 기류인 의복내기후, 의복에 의해 피부가 받는 의복압, 의복과 피부와의 접촉감 등이다. 본 연구에서는 우선적으로 인체의 상반신에서 의복기후분포를 파악하였다. 상반신에서 의복기후 분포를 평가하기 위하여 건강한 남자 10명을 대상으로 25$\pm$1$^{\circ}C$, 습도 50$\pm$5%, 기류는 30cm/sec이하의 환경에서 의복기후를 측정하였다. 실험의복은 100% 면으로 된 긴 팔, 긴바지의 속내의를 착용하게 하였다. 측정결과 가슴에서의 의복내온도는 30.6~34.7$^{\circ}C$였고, 그 평균은 33.3$^{\circ}C$였다. 또한 의복내습도는 35.6~57.9%였고, 그 평균은 38.3%였다. 등에서의 의복내온도의 분포는 31.5~35.4$^{\circ}C$였고, 평균은 33.1$^{\circ}C$였으며, 의복내습도는 36.2~55.3%였으며, 평균은 38.8%였다. 상반신인 가슴과 등에서의 의복내온도와 의복내습도간에는 차이가 없는 것으로 나타났고, 상반신 전체의 의복내온도의 분포는 30.6~35.4$^{\circ}C$, 의복내 습도의 분포는 35.6~57.9%였다.

쾌적한 스포츠웨어는 기능성에 있어서 자연환경의 변화조건과 인체의 운동 및 활동에 맞추어 열절달 및 수분전달 등을 적절히 조절할 수 있어야 한다. 이에 본 연구에서는 일반환경조건 및 강우환경조건하에서의 형상기억 투습방수직물 소재의 스포츠웨어 착용에 따른 인체생리반응 및 쾌적감을 규명하기 위하여 스포츠웨어를 제작하여, 인공기후실에서 환경조건변화에 따른 온열생리학적 특성 및 주관적 감각을 측정, 그 특성을 비교, 고찰하였다. 평균피부온은 강우환경조건에서 온도가 낮게, 변동폭이 많게 나타났다. 변화경향을 운동부하를 기점으로 온도의 상승이 나타났고, 운동 2단계에 가장 높은 온도를 나타냈으며, 이후 감소하였다. 직장온은 일반환경조건에 비해 강우환경조건에서 온도의 미세한 상승을 보였다. 의복내 기후는 두 조건 모두에서 가슴부위보다 등부위의 온·습도의 변동폭이 크게 나타났고, 강우환경조건에서의 의복내 온도를 제외하고는 모두 등부위의 온·습도가 높게 나타났다. 최고 혈압은 운동의 강도에 따라 비례하여 상승하고, 최저 혈압에는 큰 영향없이 나타났으며, 변화경향은 의복내 온도의 경향과 역으로 나타났다. 평균혈압은 일반환경조건에서 6.9mmHg 높게 나타났다. 심박수는 일반환경조건에서 4.4beats/min 높게 나타났다. 강우환경조건의 주관적 감각의 평가에서, 신체에 직접 가해지는 빗물 등으로 인해 불쾌감이 증가하였고, 운동 후에는 일반환경조건과 달리 냉감이 증가하였으며, 습윤감은 최고치에 달하였다.

The purpose of this study was to compare the effect of clothing materials and the opening of the garment on the microclimate of the skin simulating system during the coupled heat and moisture transfer. To determine the effect of size and location of openness of the garment, openness was simulated by removing parts of the spacer ring of the modelling system. To evaluate the changes of humidity and temperature of air layer in the system, buffering indice, Kd and Pr, and efficiency of openness were determined. When the openness was imparted to the system, the transport rate of heat and moisture increased abruptly; at the total openness of 26.4%, which simulated the openness of neck, armhole and waist, Kd increased at least more than three times of the closed system. As the openness increased, the effect of clothing materials decreased gradually to lose its effect at the 60% openness and approached the value of nude. Temperature regulating index showed, however, higher value than nude which was apparently due to the still air layer.

This study was performed for purpose of getting fundamental information requisite to wear velvet clothes that is more comfortable for the human body and also the environment. It was carried out in a human wearing test and thermal manikin test at the same time in a controlled-condition chamber. The experimental environment had a ambient temperature of 15$\pm$0.5$^{\circ}C$ with the relative humidity at 5$^{\circ}C$$\pm$5% and with air velocity at less that than 0.2m/sec. Velvet differ from common plain weaves in thermal properties because it's constructed in two parts one is ground part and the other part is pile part. In order to investigate the thermal resistance of velvet eight different combination of 4 velvet kinds and 2 lings kinds as experimental clothes. [(4 velvet kinds : Acetate cuprammoium Rayon Cotton Wool) (2 lining kinds : acetate viscose rayon)longrightarrow8 combination: Aa, Av, Ra, Rv, Ca, Cv, Wa, Wv: the simplified character] The results of this study can be summarized as follows : 1. For the regional thermal resistance the differences in eight clothes as well as differences in each part were significant. As a whole the breast part showed the highest thermal resistance and the leg part was higher than the shank part. The rank of the total thermal resistance was put at Wa>Wv>Ca>Cv>Aa>Av>Ra>Rv in this order. 2. Considered clothing microclimate microclimate temperature has a similar tendency to the total thermal resistance. It showed a significance in the differences of eight clothes and each parts. the belly part was highest in every combination. On the other hand for clothing humidity there was a significance between back and breast part only in the human wearing test. 3. It was indicated that CLO value was highly positively correlated with the clothings' weight and showed a high negative correlation with the air permeability.

This study establishes basic data for the development of a new Chemical, Biological, and Radioactive (CBR) protective clothing by selecting the ventilation position to optimize thermal comfort on the basis of the opening and closing of each part. Participants were eight men in their 20s who had previously worn CBR protective clothing. After vigorous exercise and perspiration, the microclimate of the clothing and skin temperature was measured. Results revealed that when the ventilation zipper was opened after exercising, the skin and clothing microclimate temperatures, which had increased during the exercise, decreased in the chest and shoulder blade regions. The clothing microclimate humidity decreased in the chest area. The change was greatest in the chest region; the skin temperature decreased by 0.2℃, the clothing microclimate temperature by 2.7℃, and the clothing microclimate humidity by 3.2%RH through ventilation. Thus, the opening that allows the exchange of accumulated heat and moisture while wearing the CBR protective clothing is efficient.
