Abstract:

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.
