Abstract
. When water content of the fabric is enhanced by the absorption of water or moisture, the air permeability of the fabric increases to inhibit in-clothes stuffiness or stickiness due to sweat and in-clothes temperature rise, while when the fabric has discharged the water into the outside environment, the air permeability of the fabric decreases to the original one to prevent the body temperature from lowering excessively because of the heat of vaporization and thus keep the in-clothes environment comfortable.
