Abstract

The invention discloses a low-carbon, energy-saving and environment-friendly after-treatment method of lycra-free pure-cotton elastic fabrics and belongs to the technical field of pure-cotton fabric after-treatment. The method includes: firstly performing desizing treatment on pure-cotton woven fabrics through desizing refining working liquor composed of biological compound enzyme and tea saponin under mild conditions; then performing bleaching treatment through low-temperature bleaching working liquor composed of Schiff alkali metal coordination compounds, peroxide and low-temperature controlled catalysts in low temperature condition; and finally treating the bleached fabrics through the liquid-ammonia mercerization technology. The low-carbon, energy-saving and environment-friendly after-treatment method is simple, comfortable in wearing, low-carbon, energy-saving, environment-friendly, high in production efficiency and applicable to industrial production, and products are elastic.

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 pretreatment process of pure cotton woven fabrics requires a large amount of caustic soda and a certain amount of surfactants. The process involves high energy consumption, large water consumption, and serious sewage discharge; in the bleaching process, common hydrogen peroxide bleaching is high-temperature bleaching and cold pad-batch Bleaching, the former process consumes a lot of energy and reduces fiber strength, while the latter has low production effi...
