Abstract

Disclosed is a method of coating a textile with aqueous urethane textile having excellent water proofness and moisture permeability, wherein aqueous urethane coating agent prepared by employing a water dispersed polyurethane resin mixture and a thickener is applied to textile fabric, the coated fabric is heat dried, and then is hardened. Accordingly, the fiber product according to the present invention is very eco-friendly product, satisfies strict standard for an advance country since formalin is not detected, and in addition, has high functionality such as water proofness, moisture permeability and cleaning durability.

Description

technical field [0001] The present invention relates to a method of applying water-based polyurethane to coat fabrics to obtain fabrics with excellent water resistance and moisture permeability. More specifically, the present invention relates to a method of coating fabrics with water-based urethane to obtain fabrics having excellent water repellency, moisture permeability, and wash resistance, which is generally used for the use of water-dispersible polyurethanes containing environmentally friendly Mixture of coating agents for fabrics. Background technique [0002] Until 1980, the urethane industry in South Korea developed centered on the clothing, shoes, bags, toys, sofas, beds and other daily necessities material industries. Now urethane is widely used as a material in automobiles, electronics, Heavy chemical industries such as civil engineering and shipbuilding, as well as aerospace engineering and medicine. The application of polyurethane coating technology in the fi...
