Eco-friendly water-repellent suede manufacturing method with improved wicking water-repellent performance

摘要

The present invention relates to a method for preparing an eco-friendly water-repellent suede material with excellent wicking water repellency. The method includes: a primary impregnation step of impregnating a polyester brushed tricot fabric with water-dispersed polyurethane to obtain eco-friendly and excellent water-repellent properties; a primary mangling step of adjusting the water content of the fabric impregnated with the water-dispersed polyurethane to be in the range of 40-60%; a stream drying step of drying the primarily mangled fabric with a steam dryer at 100°C; a buffing and processing step of buffing the surfaces of the steam-dried fabric with a buffing device; a printing step of making the color on the surfaces of the fabric uniform through gravure printing on the buffed fabric; a secondary impregnating step of impregnating the printed fabric with a water-dispersed and non-fluorine-based water-repellent agent; a secondary mangling step of adjusting the water content of the fabric impregnated with the water-dispersed and non-fluorine-based water-repellent agent to be in the range of 40-60%; a drying step of drying the secondarily mangled fabric at 100°C for five minutes; and a curing step of curing the dried fabric for ten minutes at 145-155°C.
