摘要： The present invention relates to a process for coating a textile and the obtained coated textile. The process comprises the following steps: a) bringing the textile into contact with component A) which comprises a water-insoluble salt, a water-soluble thickener and water; and b) bringing the textile contacted with component A) into contact with component B) which comprises an aqueous polymer dispersion and an acid that is able to react with the water-insoluble salt in component A), to obtain a coated textile. The process provided in the present invention does not employ organic solvents, while enables the textile obtained by coating having good hand feeling, such as softness.

摘要： The present invention relates to an aqueous dispersion of polyurethane and a method for 5 preparing the same, use thereof in a coating composition, and a coated product. The aqueous dispersion of polyurethane comprises a polyurethane polymer which is obtained by a reaction of a reaction mixture comprising a polyurethane prepolymer A) and an isocyanate-reactive component B), said polyurethane prepolymer A) being obtained by a reaction comprising the following components: A1) a polyisocyanate which has a 10 functionality of not less than 2; and A2) a multifunctional polyether polyol which has a functionality of not less than 3 in an amount of 1% to 30% by weight, based on the amount of said reaction mixture as 100% by weight. The aqueous dispersion of polyurethane according to the present invention is well dispersed, and is capable of forming a coat with good waterproof, moisture permeability and washing resistance.
