Abstract

The invention relates to desizing and refining working solution of a pure cotton woven fabric and belongs to the technical field of after treatment of the pure cotton woven fabric. The desizing and refining working solution comprises tea saponin, zinc phthalocyanine and biological complex enzyme. The biological complex enzyme is formed by compounding pectate lyase, cellulase, amylase and protease. According to the invention, the desizing and refining working solution is formed by the tea saponin, the zinc phthalocyanine, the biological complex enzyme and water; when the boiling-off refining effect of the fabric is ensured, a method of using a great amount of caustic soda in an original desizing process is avoided, so that not only is the direct damage of the caustic soda to the fibers avoided, but also the treatment cost of wastewater pollution in the desizing process is effectively reduced, and thus, the sewage treatment cost in the production process is saved; and the desizing and refining working solution can be used for desizing under the condition of the temperature of 50 to 70 DEG C and is beneficial for reducing the production energy consumption cost.

Description

technical field [0001] The invention belongs to the technical field of after-finishing of pure cotton woven fabrics, in particular to a post-finishing process for forming elastic pure cotton woven fabrics through after-finishing. Background technique [0002] Cotton fibers contain impurities such as waxy substances and pectin substances, as well as cottonseed hulls that adhere to the cotton. These co-growths will affect the wettability and dyeing properties of cotton fibers, so they must be fully removed. The traditional pre-treatment process of pure cotton woven fabrics requires a large amount of caustic soda and a certain amount of surfactants. This process requires high energy consumption, large water consumption, and serious sewage discharge. In addition, the processing process consumes high energy and damages the fiber strength. Contents of the invention [0003] The purpose of the present invention is to provide a desizing and refining working fluid which avoids a s...
