However, in recent years, on the premise of functionality, it has become important to develop clothes that take comfort demands into account. In particular, it is useful to make a preliminary evaluation of the material and design of the clothes in consideration of the sense of heat and humidity when wearing the clothes.
[0003]
However, in the comfort evaluation by the human body, there are problems such as low reproducibility, individual differences, and difficulty in evaluation under special environmental conditions.
