Abstract

The invention discloses a waterproof treatment method for grey cloth. The waterproof treatment method comprises the following steps: 1) performing overturning, cold pad-batch, boiling off, shaping, bottom dyeing and printing on the grey cloth; (2) drying the grey cloth after printing is completed, and then performing ageing and drying; 3) carrying out soaping and color fixing treatment; 4) coatingone side with an adhesive by using a coater by the coating thickness of 1-3 microns, and performing drying; 5) subsequently coating the adhesive with waterproof paint by using the coater by the coating thickness of 10-50 microns, and performing drying; and 6) performing calendering treatment. The waterproof paint is prepared from the following components in parts by weight: 6-10 parts of silicondioxide, 10-15 parts of calcium sulfate, 1-2 parts of polybutyl acrylate, 2-3 parts of 3-aminopropyl trimethoxysilane, 2-3 parts of polyacrylamide, 3-5 parts of polyvinylpyrrolidone, 6-10 parts of phthalic anhydride, 5-10 parts of maleic anhydride, 2-3 parts of softening oil and 5-20 parts of deionized water. The cloth treated by the waterproof treatment method provided by the invention has good waterproofness and waterproof durability, and meanwhile, the softness and comfort of the cloth are not influenced.

Description

technical field [0001] The invention relates to a gray cloth finishing method, in particular to a gray cloth waterproof treatment method. Background technique [0002] In the current society, water and oil are common pollutants in people's clothing fabrics and other fabrics in daily life and work, especially fabrics used in some special environments are more susceptible to water, oil and other dirt. Contamination, such as machinery manufacturing, equipment maintenance, automobile industry and other industries, this puts forward new performance requirements for textiles. Waterproof and oil-resistant textiles can prevent oily and water-based pollutants from staining, and the finished textiles will hardly change the style of the original textiles. [0003] There are also some reports about fabric waterproofing in the prior art. For example, the invention application with application number 201710381450.3 discloses a preparation process of a single-sided waterproof and oil-pro...
