摘要

A water-vapor permeable, waterproof coated fabric having a fibrous base fabric, and a porous film coated on one side of the base fabric. The porous film comprises a synthetic polymer composed mainly of a polyurethane resin and inorganic fine particles having a mean particle diameter of not more than 0.1 mu m. In the porous film, microcells intercommunicate in the thicknesswise direction of the film to form a honeycomb skin core structure having a diameter of 1 to 20 mu m. The porous film has a multiplicity of micropores having a diameter of not more than 1 mu m. The coated fabric waterproof and water-vapor permeability characteristics sufficient to meet such performance characteristics required in various applications, such as rainwears, military garments, and sportswears.
