Production method of environment-friendly water-repellent synthetic leather using non-fluorine water repellent agent

摘要

The present invention relates to a method of manufacturing an eco-friendly water-repellent synthetic leather using a non-fluorine water repellent, and includes a water-dispersible polyurethane and a non-fluorine water repellent in a polyester tricot brushed fabric to maximize water repellency while being eco-friendly and harmless to the human body. The impregnation step of impregnating the water-repellent mixture for impregnation, the mangle step of adjusting the moisture content to 40-80% by compressing the fabric impregnated with the impregnating water-repellent mixture, the water-dispersible polyurethane and non-fluorine water repellent on the fabric that has undergone the mangle step A silver layer forming step of coating a water-repellent mixture for coating containing, a drying step of hot air drying the fabric subjected to the silver layer forming step at 90° C. to 110° C. for 2 to 4 minutes through a dryer, and 140° C. It includes a curing step of curing in a curing machine for 4 to 6 minutes at ~150 ℃.
