<p>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:20-80wt% (on a solid basis) water-dispersible polyester (contg. metal sulfonate groups of 5-1,000 equivalents /10<6>g and having a softening point of 40-200 deg.C and a MW of 2,500-30,000) and/or water-dispersible polyester- urethane resin (A) (having a MW of 3,000-10,000 obtd. by reacting an isocyanate with a polyester contg. metal sulfonate groups and having a MW of 500-5,000), is mixed with 80-20wt% (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 0.1-10wt% solids. After drying, a heat treatment is carried out at 140-200 deg.C.</p> |
