Abstract

PURPOSE: To make a fine, porous and air-permeable coating layer on a substrate, by preparing a volatile organic solvent solution of linear polyurethane having fine short fibers scattered as suspension and spraying the solution onto the surface of the substrate.
CONSTITUTION: A mixture composed of a linear polyurethane resin soluble in a solvent and fine short fibers is formed to a viscous short fine fiber shape on a surface of a foamed article, e.g. polyurethane by an appropriate method. The fiber- shaped mixture is sprayed onto a surface of a substrate, and deposited as a layer on the surface. Thus, the surface of the substrate is coated with fined fibers piled up in random manner. The fiber-shaped mixture in a state having a viscosity is bombarded onto the substrate, so that the fine fibers coherently adhere onto the surface of the substrate and also adhere together by themselves. Consequently, it is possible to make an elastic continuous coating layer on nonwoven fabric having a sufficient air-permeability.
