Abstract
The present work deals with the theoretical prediction of warmth parameters of clothing assembly. Theoretical expressions are derived for calculating both air flow resistance and thermal resistance of clothing assembly. Three different cases which represent the most common wearing cases in winter season were selected for applying the theoretical expressions. The derived relations were found to be fairly close to those observed experimentally. Also an empirical relationship is fitted to the measured thermal resistance data of clothing assembly using stepwise multiple regression analysis. The regression analysis relates the thermal resistance of the clothing assembly to the parameters of weight per unit area, thickness and air resistance. This empirical relationship is shown to predict the thermal resistance of clothing assembly accurately.
