Abstract

The invention discloses a manufacturing method of durable antistatic water-repellent fabric. The method includes the following steps of firstly, selecting fabric woven from polyester fiber or nylon fiber with yarn fineness of 7 D to 70 D as base cloth; secondly, conducting antistatic processing on the base cloth in the first step through antistatic finishing liquid, adjusting pH through citric acid, conducting twice immersing and once rolling, conducting non-contact type infrared pre-drying, conducting drying through a direct-contact type roller, and conducting cooling so that continuous antistatic resin film can be formed on surfaces of fiber; thirdly, conducting water-repellent processing on the fabric obtained in the second step through water-repellent finishing liquid, conducting once immersing and once rolling, conducting baking so that an insoluble water-repellent thin film can be formed on the surface of the antistatic resin film, and obtaining the durable antistatic fabric. The method has the advantages that through the cooperation of an antistatic agent and a water-repellent agent, emulsified siloxane quaternary ammonium is evenly distributed in the antistatic agent with waterborne polyurethane resin as carriers, and the optimal antistatic effect and water-repellent effect are achieved.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a method for manufacturing a durable antistatic water-repellent fabric. Background technique [0002] In the post-treatment process of existing fabrics, in order to make the fabric have antistatic effect and water repellent effect at the same time, the most conventional method is to mix the antistatic agent and water repellent agent according to a certain ratio, and then perform padding and baking on the fabric. baking treatment. [0003] Because conventional water repellents are weakly cationic, the antistatic agents used in conjunction with them are generally cationic or nonionic. Cationic antistatic agents include quaternary ammonium salts, polyethylene polyamines, etc. Certain toxicity, poor light fastness, dye easy to change color. Nonionic antistatic agents include polyoxyethylene alkyl ethers, polyoxyethylene alkylamines, and the like. However, the surface of polyester fibers is...
