Interdisciplinary studies on the optimization of clothing under hot and humidified conditions in East Asia

有关服装舒适度、环境温度和相对湿度的环境数据是在日本和东亚典型的热带国家之一泰国编制的。为模拟实验和计算提供了条件。从生理和心理基础研究的角度，对热湿条件下年轻和老年女性受试者的服装舒适性进行了研究。在这种情况下，使用棉花和聚对苯二甲酸乙二醇酯作为服装材料，它们在吸收、吸附和透射水蒸气方面具有不同的性能。此外，还对床上舒适性和鞋上舒适性进行了研究，以掌握影响床上舒适性的因素。通过出汗热人体模型表征了水蒸气通过衣服的传输。并对控制蒸发散热的实验因素进行了探讨。另一方面，利用光栅剖面系统研究了皮肤与衣服之间的间隙，作为传热模拟的基础信息。传统服饰作为实验对象。采用二维计算技术进行了传热模拟。主要考察了服装开口对服装中热量和水汽传递的影响。此外，还通过日式睡垫模拟了一维传热。

Environmental data with respects to clothing comfort, ambient temperature and relative humidity, were compiled in Japan and Thailand, one of the typical tropical countries in East Asia. They are informative to set up the condition as for the simulation experiment and computation.Not only young but also older female subjects were examined under hot and humidified conditions to investigate their clothing comfort from the standpoints of physiological and psychological basic studies. In this occasion, cotton and polyethylene terephthalate were used as clothing material which have contrasted properties in absorption, adsorption and transmission of water vapor. Moreover, the comfort in bed and shoe was investigated to grasp the factor to control it.The transmission of water vapor through the clothes was characterized using a sweating thermal manikin. The experimental factors to control the evaporation heat dissipation were also examined. On the other hand, the gap between skin and clothe was investigated with a grating system for profiling as a basic information to the heat transfer simulation. Tranditional costumes were included as experimental objects.The heat transfer simulation was made using a two dimensional computational technique. The effect of opening of clothing was basically examined on the heat and water vapor transfer in clothing. In addition, one dimensional heat transfer was simulated through a Japanese style sleeping pad.
