THE METHOD FOR PROMOTING ABRASION-DURABILITY OF SURFACE OF NANO FIBER MEMBRANE USING AQUEOUS POLYURETHANE RESIN SOLUTION

摘要

The present invention provides a method for promoting a surface wear resistance of a nanofiber membrane by using an aqueous polyurethane resin solution, the method comprising the steps of: preparing an aqueous polyurethane resin solution by mixing a polyurethane resin aqueous dispersion having an excellent storage stability, initial adhesion, and humidity and temperature resistance, a dye or pigment, and an inorganic filler; printing a continuous or discontinuous and a structured or non-structured pattern on a nanoweb membrane surface of a textile-nano membrane 2-layer textile laminating a nanoweb membrane made by an electrospinning or a melt spinning to the fabric by using a driving roller where the aqueous polyurethane resin solution is patterned.
