The after-finishing agent provided by the invention is easy for industrial application, and can improve the color quality of natural colored cotton products.

Description

technical field [0001] The invention relates to a finishing agent for darkening and fixing colors of natural colored cotton. Background technique [0002] The production and processing of cotton textiles is an industry that consumes water, electricity, and high pollution. Natural colored cotton products do not require bleaching and dyeing processing, so they have the advantages of environmental protection and processing costs. With the change of people's life philosophy, healthy and environmentally friendly natural colored cotton products are increasingly favored, and the development of natural colored cotton processing technology is in line with the direction of industrial development. In recent years, it has been found that natural colored cotton has good biological activity, such as antibacterial and anti-oxidation functions, which has enhanced the intrinsic value of this environmentally friendly textile material. [0003] However, natural colored cotton still has some ...
