Analysis of Sweating through Clothing Materials due to Ventilated Sweat Capsule Method
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.15 Vol.15】
In order to clarify the effect of clothing materials on the evaporation of the sweat, the clothing material was applied on the skin covered by the sweat-capsule and the change in relative humidity due to sweating through the clothing material was determined by capacitance hygrometer-ventilated capsule method.
There was no difference in sweat volume among the clothing materials of cotton, silk and nylon. The increase in relative humidity through clothing materials were slightly delayed after sweat-onset. The smaller decrease rate of evaporation after the end of heat load and the longer recovery time of relative humidity compared to those in control capsule without any clothes were observed through the clothing materials.
These effects were significant in the order of cotton > silk > nylon among three materials, and in the order of non-contact (3 mm above the skin) > partial contact > contact on the skin among the three kinds of fashions of contact with the skin surface. The former result was agreed with the drying characteristics of the clothing materials.
