Embodiment 1

[0025] The pure cotton denim fabric with a width of 162cm, a weight of 10OZ, a color of extra dark blue, and a weave of 1 / 3 right diagonal is used as the finished fabric. The mass percentage of fluorine-containing emulsion in the water-repellent finishing agent is controlled to 55%, and the resin is finished. The mass percentage of softener is 28%, the mass percentage of softening agent is 16%, and the mass percentage of thickener is 1%. The pH value of the water-repellent finishing agent is controlled at 5.0. If there is any deviation, it can be adjusted by adding a pH buffer solution. The pH value of the cloth surface is 5.5, which can be adjusted by soaking the denim fabric in acetic acid or citric acid solution for 1-10 minutes , wherein the fluorine-containing monomer in the fluorine-containing emulsion is 1, and the concentration of perfluorobutyl 1-dihydroacrylate is 20g / l, the concentration of dimethylolurea in the resin finishing agent is 5g / l, and the concentration of...

Abstract

The invention relates to a water repellent finishing agent, which comprises the following components in percentage by mass: 50 to 80 percent of fluorine-containing emulsion, 10 to 30 percent of resin finishing agent, 5 to 20 percent of softening agent and 0.3 to 2 percent of thickening agent; and pH value buffer solution is added to adjust the pH value of the water repellent finishing agent to between 4 and 7. The invention also relates to a method for manufacturing moisture absorbing and sweat releasing jean fabric by using the water repellent finishing agent, which comprises the following steps: performing water repellent coating finishment on the inner side of the jean fabric by using the water repellent finishing agent; and not treating the outer side of the jean fabric to keep the hydrophilicity of cotton, wherein the water repellent coating finishment process comprises the steps of coating the inner side of the jean fabric, pre-drying, baking, and cooling and cloth falling; the pre-drying temperature is between 80 and 135DEG C, and the time is 1 to 150 minutes; and the baking temperature is between 110 and 170DEG C and the time is 2 to 10 minutes. By adopting the water repellent finishing agent and the method for manufacturing the moisture absorbing and sweat releasing jean fabric, common jean fibers can be manufactured into the moisture absorbing and sweat releasing jean fabric with good washing fastness and strong processability.

Description

technical field [0001] The invention belongs to the technical field of textile fabric manufacturing, and in particular relates to a water-repellent finishing agent for making moisture-absorbing and sweat-wicking denim fabrics and a manufacturing method for making moisture-absorbing and sweat-wicking denim fabrics with the water-repellent finishing agent. Background technique [0002] Traditional denim clothing is a clothing that leads the global trend. However, with the continuous development of textile technology and the change of people's consumption concepts, there are higher requirements for the functionality, comfort, health, environmental protection and health care of denim fabrics. , The moisture wicking property of denim has become the first choice for people to buy denim. However, traditional denim fabrics have single functions, low grades, poor comfort, and low added value, which cannot meet people's needs for denim clothes. Therefore, the market development prospe...
