Effects of Air Permeability of Sportswear on Body Temperature and Sweat Responses
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.16 Vol.16】
The effects of four different types of clothing (polyester or cotton, and high air permeability or low air permeability) on body temperature and sweat responses were studies. Chest sweat rate in clothing with low air permeability tended to be lower than in clothing with high air permeability. Tympanic temperatures were higher in cotton clothing with low air permeability, and in polyester clothing with high air permeability. The temperature and humidity in clothing microclimate at chest decreased greatly in polyester clothing with high air permeability. The temperature of clothing surface in cotton clothing showed greater change than in polyester clothing.
The microclimate in clothing different in material and air permeability was measured using a sweating thermal manikin. While the manikin was sweating, the increase in temperature in clothing of cotton was larger than that in clothing of polyester. Differences of moisture properties appeared immediately after the start and stop of sweating. Different materials of clothing caused difference in moisture pressure inside and outside clothing. It is necessary for analysis of the moisture transfer to measure humidity with many sensors in clothing.
