运动引起服装热阻变化的实验分析

Experimental analysis of the clothing thermal resistance change caused by human body motion

为分析常规着装下人体运动对服装隔热、保暖性的影响,从服装热力学、卫生学与运动学角度出发,通过实验统计,拟合分析了在"静止"和"运动"两种情况下,人体皮肤温度、环境温度等服装热舒适性指标的变化,对服装热阻的影响.实验结果表明,运动环境下,环境温度、相对湿度、人体行走的步速以及环境风速等物理参量的变化均会对服装热阻产生一定的影响.其中,人体运动引起服装内空气层的流动以及服装衣料纱线间死腔空气量的多少,是影响服装热阻变化的最主要因素.

In order to analyze the influence of human body motion on clothing thermal comfort and heat retention in normal dress condition,from the perspective of thermodynamics,hygiene and kinesiology,the thermal comfortable index of clothing was analyzed such as skin temperature and environment temperature in the cases of staticness and motion.The results show that the wind speed,different pace,different body surface temperature,and different relative humidity have great influences on clothing thermal resistance when people are in motion,among which the flow of air layer of clothing and the amount of dead space air between the fabric yarn are major factor affecting clothing thermal resistance.
