고보온성 패딩의 중량과 두께 변화에 따른 보온율과 clo의 거동

Abstract

In the previous study of constant packing density when padding low thermal insulation, heat resistance and thermal insulation ratio (%) was determined to increase proportionally with the thickness. This study investigates the change in the thermal insulation ratio and clo with increase in weight and thickness of the padding, which has high thermal insulation performance, and the result is as follows. When the weight or thickness of the padding is small, the initial thermal insulation ratio (%) increases proportionally with the weight or thickness. Unlike in previous studies, in this study, the growth rate of thermal insulation ratio decreases from a certain point, and the proportional relationship does not appear. Thereafter, the growth rate of thermal insulation ratio is convergent near zero. Moreover, thermal insulation ratios do not increase even though the weight or thickness increases. If the padding has high thermal insulation performance, the clo increases proportionally with the weight or thickness of the padding. Furthermore, with the aforementioned behavioral characteristics of high thermal insulation padding, high insulation products can be used to improve vitality and survival rate of the wearer because high insulation padding with less weight and thickness than low insulation padding can achieve the same thermal insulation ratio.
