Abstract

The invention discloses a production process of a high-density nylon fabric. The process comprises the following steps: (1) unwinding and sewing; (2) performing desizing pretreatment; (3) presetting at 170 DEG C, namely adding 5-6g/L isopropanolamine and a 30g/L anti-yellowing agent, wherein the liquid content is 40 percent; (4) dyeing; (5) fixing color, adding a 5g/L anion color fixing agent and 4g/L acetic acid, performing color fixing treatment for 50 minutes and washing with clear water; (6) dehydrating and scutching; (7) carrying out after finishing, namely adding a 30g/L water-proofing agent, a 5g/L silicone softening agent, a 8g/L crosslinking agent and 4g/L fatty alcohol-polyoxyethylene ether, wherein the liquid detention rate is 40 percent, the drying temperature is 120 DEG C and the baking temperature is 190 DEG C; and (8) calendering. By adopting the production process, the problems of easiness in high-temperature yellowing, poor ultraviolet resistance, poor water repellency, poor oil repellency, poor water washing resistance, low color fastness, not ideal downproofness and the like due to the adoption of a non-reasonable production process in the existing production process of high-density nylon fabrics are solved.
