Embodiment Construction

[0047] refer to figure 2 , according to the first embodiment of the present invention, the manufacturing method of highly water-repellent artificial leather mainly includes first and second stages, wherein the first stage is to form a semi-finished artificial leather, and the second stage is to produce a semi-finished artificial leather similar to genuine leather texture to form the finished artificial leather. The first stage includes steps 204 to 213. First, a base cloth 252 is provided (step 204), and the base cloth 252 is impregnated with a water-repellent polyurethane resin composition to form an impregnated layer 254 in the base cloth 252 ( Step 206), coating the base cloth 252 with the polyurethane resin composition with a water-repellent agent to form a coating layer 256 on the base cloth 252 (step 208), and then coating the impregnated layer 254 and Layer 256 is solidified (step 210), washed (step 211) and dried (step 212) to form a water-repellent artificial leathe...

Abstract

This invention relates to a manufacturing method for artificial leather including the following steps: providing a piece of basic cloth, forming a PUR resin impregnation layer with a water-driven agent in said cloth and a coated layer on said cloth to freeze, wash and dry said impregnation layer and the coated layer to form a kind of water-driven artificial leather and then process the fluorine water-driven agent to form a high water-driven artificial leather.

Description

technical field [0001] The present invention relates to a kind of artificial leather, more particularly relates to a kind of artificial leather manufacturing method, through the treatment of water-repellent agent, make artificial leather have high water repellency. Background technique [0002] refer to figure 1 , the known artificial leather manufacturing method mainly includes the first and second stages, wherein the first stage is to form the artificial leather semi-finished product, and the second stage is to produce the artificial leather semi-finished product with a texture similar to genuine leather to form the artificial leather finished product. The first stage includes steps 104 to 113. First, a base cloth is provided (step 104), and the base cloth is impregnated with the polyurethane resin composition for impregnation to form an impregnated layer in the base cloth (step 106), and then the coated Coating the base cloth with a polyurethane resin composition to for...
