Aqueous treating agent

Abstract

Abstract PURPOSE: To provide an aq. treating agent which gives a treating effect rich in durability and weather resistance as a feeling-improving agent for textures, consisting of a specified water-dispersible polyester (urethane) resin and a vinyl ester or acrylic ester polymer latex. CONSTITUTION: 20W80wt% (on a solid basis) water-dispersible polyester (contg. metal sulfonate groups of 5W1,000 equivalents /10 6 g and having a softening point of 40W200°C and a MW of 2,500W30,000) and/or water-dispersible polyester- urethane resin (A) (having a MW of 3,000W10,000 obtd. by reacting an isocyanate with a polyester contg. metal sulfonate groups and having a MW of 500W5,000), is mixed with 80W20wt% (on a solid basis) vinyl ester and/or acrylic ester polymer latex (B) to obtain an aq. treating agent. This treating agent is coated on textures in such an amounts as to give 0.1W10wt% solids. After drying, a heat treatment is carried out at 140W200°C. COPYRIGHT: (C)1981,JPO&Japio
