单向导汗织物的热舒适性

为探索单向导汗织物在潜汗条件下的热舒适性，建立织物在潜汗条件下传热传湿规律的数学模型。选用2种典型的单向导汗织物与1种普通织物，利用纺织品热湿物性参数测试装置作对比实验，获得了样品的总传热量、微气候和环境干湿球温度以及模拟的人体皮肤温度等数据。采用二元回归拟合出织物热舒适性能参数：干球系数和湿球系数。发现在潜汗条件下，不仅仅是普通织物正反面的热舒适性能相近，就是具有单向导汗功能的织物，其正反面的热舒适性能差别也不大。

Thermal comfort of single-direction-sweat-transmitting fabric

To explore the thermal comfort of the single-direction-sweat- transmitting fabric under the condition of insensible perspiration, a mathematic model was established by analyzing the law of heat and moisture transfer of the fabric. Two typical single-direction-sweat-transmitting fabrics were selected as samples and a common fabric as counterpart in testing heat and moisture transfer properties, and the data on the total heat transfer, and dry and wet bulb temperatures under micro-climate and ambient conditions of the samples, as well as stimulated skin temperatures of human body were obtained. The thermal comfort indexes of dry-bulb coefficient and wet-bulb coefficient of the fabrics were fitted by binary regressive analysis. It was found that under the condition of insensible perspiration, the thermal comfort of the general fabric is similar on both sides, and so is the case with single-direction- sweat- transmitting fabrics.
