Abstract: The switch of clothing’s wearing methods will result in the change of heat transfer ways and quantity through clothing. Three associated factors were extracted from the wearing methods switch in this paper, including body surface area coverage, clothing openings and clothing surface area change rate. The corresponding indices and measuring proposals for these three factors were also decided. Correlation Analysis of both single factor and multi-factors were conducted to compare the effects and interactive effects of the three factors to clothing thermal insulation properties. It was found that there was a significant positive correlation between BSAC and thermal insulation, whereas a significant negative correlation between VI and thermal insulation. In the process of wearing methods switching, BSAC contributed the greatest and AR contributed the least to the clothing thermal insulation change.

Key words: wearing method, thermal insulation, body surface area coverage, ventilation index
