PURPOSE: To obtain a material suitable for sports, such as especially athletic wear, ski wear, outdoor wear, etc., always providing a body with a comfortable environment irrespective of an environmental temperature. CONSTITUTION: At least one side of a fiber substrate 5 is coated with 8-25wt.% polar organic solvent solution of a polyurethane elastomer containing 20.5-30wt.% of fine powder of wood, 30.05-10wt.% of a natural gas-containing spherical fine particle and 0.1-5wt.% of a polyisocyanate cross-linking agent, then immersed in a coagulating bath, gelatinized, washed with water and dried to form a coating film having a slight change in water vapor permeation against change of temperature of the open air and having 5-60μm thickness. Consequently a water vapor permeable waterproof fabric keeping excellent waterproofness and water resistance of the water vapor permeable and waterproof fabric, having a slight change in water vapor permeation against change of temperature of the open air, excellent in condensation preventing properties and heat insulating properties is obtained. |
