Abstract:
     Natural leather itself has air permeable nature. If water-proofing matter is coated on it to fill the gap between leather fibre bundles, or the after-wetting angle between fibre surface and water is increased to make it unable to suck and deliver water, or the both are implemented, the natural leater will have both air permeable and water-proof characteristics.
