A Study on the Initial Maximum Value of Heat Flux, $q_{max}$ of Wool Fabrics (Part I) - The correlation between $q_{max}$ and thermal conductivity, thermal transmittance, surface air cavity of wool fabrics -

양모 복지의 초기열류속최대치($q_{max}$)에 관한 연구( I ) -열전도도, 열통과성, 표면기공도와의 상관성을 중심으로-

In this study, we discussed about the factors effected upon the initial maximum value of heat flux ($q_{max}$). Thermal conductivity, thermal transmittance and surface air cavity of wool fabrics were examind and their correlation to the $q_{max}$ was studied. The factors were examined which had an effect upon the $q_{max}$ of an objective measure of warm/cool feeling. It was simulated by Thermo-Labo apparatures. We selected twenty sorts of pure wool woven fabrics for men's fall -winter cloth (all Wool). The conclusions are as follows; 1. There was not a certain correlation between the $q_{max}$ and the thermal conductivity of wool fabric. 2. When the fabrics touched on the copper plates, the thickness of wool fabric had a negative correlation to the $q_{max}$. The thermal transmittance had a positive correlation. Both of them had a good correlation to the $q_{max}$. 3. As a major factor, the thickness of fabric effected on the $q_{max}$.
