Title:
AQUEOUS DISPERSION OF POLYURETHANE RESIN, NONPOROUS FILM, AND METHOD FOR PRODUCING MOISTURE-PERMEABLE WATERPROOF FABRIC
Document Type and Number:
WIPO Patent Application WO/2011/132581
Kind Code:
A1
Abstract:
Disclosed is an aqueous dispersion for a nonporous film in a moisture-permeable waterproof fabric such that a polyurethane resin, which is obtained by reacting an isocyanate-terminated urethane polymer and a chain extender (F), is dispersed in water, and the particle diameter is 500 nm or less for cumulative passage of 90%. The isocyanate-terminated urethane polymer is produced by reacting polytetramethylene ether glycol (A), a polyol (B) having an oxyethylene group, an alkylene diol (C) having a branched alkylene group, an organic polyisocyanate (D), and as necessary, a polyol (E) having a carboxy group.
