S2: and (2) dyeing at low temperature, namely dyeing the fabric at the temperature of 50-110 ℃, and adding 4 mass percent of UV-SUN auxiliary agent in terms of the weight of the fabric into the dye, wherein the heating rate is 0.4-0.6 ℃/min. Specifically, after the fabric is dyed and heated to 50 ℃ at the speed of 0.6 ℃/min, the temperature is heated to 95 ℃ at the speed of 0.4 ℃/min, the temperature is maintained for 90min, then the temperature is reduced at the speed of 3 ℃/min, and the temperature is controlled below 50 ℃.
S3: softening and shaping by water repellent at low temperature, performing water repellent treatment on the dyed fabric by using a water repellent auxiliary agent, wherein the water repellent temperature is 80-145 ℃, so that the water repellent auxiliary agent on the surface of the fabric enters a half-cooked state, the fabric is easy to dry because of being thinner, the water repellent agent is not required to be formed into a film as fast as possible, basic drying is performed firstly, the curing time is reserved to the baking completion of the coating at the back, specifically, the fabric is conveyed into a drying oven at the speed of 40m/min, the drying temperature of the first section to the tail section is changed into 80-130-145-130 ℃ in sequence, and the drying temperature of the first section to the tail section is changed into nine sections.
S4: and (4) coating, namely coating the fabric obtained in the step S3, wherein the coating mode adopts release paper transfer coating, coating is carried out by a circular knife operated by release paper transfer equipment, the coating is coated on the release paper, and the coating is adhered to the fabric after baking.
S5: after coating, the fabric is sent into a ripening chamber for ripening treatment, so that the fabric in a half-ripened state is completely ripened.
The method reduces the permeation of glue to the cloth, compared with a direct coating method, the tearing strength is obviously more advantageous, and the gram weight of the coating is controlled in ISO 3801:1977, 515-20G/M2The water pressure is better controlled and can reach ISO 811:2018(60cmH2O/min) 4000-5000MMH2O hydrostatic pressure, the film forming is more uniform, and the tearing strength can reach 55-60N.
