Eco-friendly water-repellent synthetic leather using non-fluorine water repellent

摘要

The present invention relates to an eco-friendly water-repellent synthetic leather using a non-fluorine water-repellent agent, and is eco-friendly and harmless to the human body, and at the same time, a polyester tricot brushed fabric layer, a water-dispersible polyurethane and non-fluorine in the brushed fabric layer, to maximize water repellency. A non-fluorine water-repellent impregnation layer formed by impregnating a water-repellent mixture for impregnation containing a water-repellent agent, and a silver layer formed by coating a water-repellent mixture for coating on the surfaces of the brushed fabric layer and the non-fluorine-free water-repellent impregnation layer, and the non-fluorine water-repellent The impregnated layer and the silver layer are hot air dried at 90°C to 110°C for 2 to 4 minutes and then cured in a curing machine at 140°C to 150°C for 4 to 6 minutes.
