Abstract

Method for the treatment of microporous materials, characterized in that it comprises providing a sheet material that has a transmission to water vapor of at least; 100 g/m2/24 hours and having at least one surface area of microporous elastomeric polyurethane material with micropores having a diameter greater than one micron that pass through the outer surface of said area, and form on said outer surface an adherent layer of elastomeric polyurethane material whose layer transmits water vapor and has at most only a minor proportion of its volume occupied by pores whose diameter is greater than 0.3 microns, said adherent layer being formed by a process that involves applying a solution of elastomeric polyurethane material to said outer surface and coagulate said solution by anointing a non-solvent, joining and covering said adherent layer to said micropores that pass through the outer surface of said area, having the polyurethane material quoted from said surface area and the mentioned adherent layer an intrinsic viscosity of at least 0.7.
