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.

The factors affecting clothing comfort are temperature, humidity, and air velocity of clothing microclimate which is the temperature and the humidity between the skin surface and the innermost garment, clothing pressure and clothing texture to the skin. This study was designed to estimate the distribution of clothing microclimate on the upper body. All the data of this study were collected from volunteered male subjects in the controlled climate chamber laboratory in which the temperature was $25\pm1^{\circ}C$, the relative humidity $50\pm5%$, and the air velocity 30cm/sec. All subjects should wear long-sleeved inner wear and pants woven in 100% cotton. Clothing microclimate temperature at 16 sites on the chest and 16 sites on the back was measured. The results were as follows: the distribution of the clothing microclimate temperature on the upper body was $30.6\sim34.7^{\circ}C$ on the breast and $31.5\sim35.4^{\circ}C$ on the back. While a mean temperature on the chest was 33.3$^{\circ}C$, it was 33.1$^{\circ}C$ on the back.

Persimmon juice dye-printed fabrics with printing were used for a Galot one-piece dress. The Galot dress was assessed in comparison to a white undyed one-piece dress of the same design through a wearing test conducted in a climatic chamber with an air temperature of $30{\pm}1^{\circ}C$, $50{\pm}5%$ R.H, and 0.2m/sec air movement on 4 healthy female subjects in their 20s. The subjects went through a 30-min stable period, a 30-min exercise of walking on a $5^{\circ}$ slope treadmill at 70m/min period, and a 20-min recovery period. In addition, a physiological reaction and subjective sensation were estimated. The results showed that significant differences were mostly observed from a sweating period that occurred during the latter half of the exercise. More specific results are as follows. First, skin temperature on the chest and mean skin temperature were significantly higher (p<.01) in rayon dyed sample dresses. Second, micro-humidity on the back showed a significant difference (p<.01). Both cotton and rayon persimmon juice dyed sample dresses produced lower microhumidity than their counterparts and as for cotton the difference occurred over the entire experimental period; however, it occurred after the middle of the exercise period for rayon. Third, the sweating rate on the back decreased in both cotton and rayon with persimmon juice dye but no significant difference was observed. Fourth, subjective three sensations revealed significant differences between cotton and rayon (p<.01), indicating that the subjects felt more cool, dryer and more comfortable in a cotton Galot. As described above, the analysis of physiological responses and the subjective sensation of undyed and dyed clothing shows the effect of persimmon juice dyeing. Persimmon juice dyeing also seemly increased air permeability, moisture regain and permeability facilitating body heat ventilation, as micro-humidity and sweat rate were lowered. However, this was not shown consistently in subjective responses on comfort especially when wearing rayon dresses.
