Study on Dynamic Heat-moisture Transfer Properties of Summer Fabrics Using Microclimatic Method
摘要
The temperature and humidity of the microclimatic zone of summer fabrics in the course of sweating - evaporating - drying were measured with an apparatus specially made for the purpose. It is pointed out that temperature and humidity changes in quantitative perspiration evaporation process in the microclimatic zone can express the dynamic heat-moisture comfortability. Characteristic values include temperature decline speed, temperature rising speed, humidity rising speed, humidity balance value, and humidity decline speed. Fabrics with good air permeability are beneficial to improving comfortability of summer fabrics, while temperature rising speed and humidity decline speed in the microclimatic zone of thick and heavy fabrics with good hygroscopicity are relatively slow. Through comparing fabrics'dynamic heat-moisture curves obtained respectively with Microclimatic Method and Heat Loss Method, the two methods are identical essentially.
