PDF On the Layered System of Clothing for Outdoor Sports

【Supercategory:7. DESCENTE SPORTS SCIENCE Subcategory:7.10 Vol.10

 The water vapor transport through the layered system of clothing for outdoor sports were discussed. The total insulation in man is made up of sum of the insulation affored by clothes, air, sweat and tissues. A function of clothing is to keep the comfort of body from the environment, this is especially need when outdoor sports. Over heating when exercising in the cold with loss of insulation associated with the production of sweat, and thus of water vapor, is a well recognized hazard.
 A new apparatus which can evaluate the rate of moisture transfer through the fabric layered system was developed. This apparatus has of two chambers located on both side the layered system, one is keeped at high constant water vapor pressure by hot water and the other is keeped at lower water vapor pressure by a freezing machine. The transit of water vapor pressure in middle layer of layered system was measured, and it was cleared that the water vapor pressure in middle layer has relation on the moisture absorption of fabrics.
 The results of this study were suggested that the complex system of the different moisture regain fabrics must be under consideration to the layered system for outdoor sports.
