Abstract

The invention discloses a low-temperature oxygen bleaching activator for a pure cotton fabric, and belongs to the technical field of textile assistants. The low-temperature oxygen bleaching activatorfor the pure cotton fabric, prepared in the invention, is composed of xylanase, urease, horseradish peroxidase, laccase, a carrier dispersion, plant polyphenol, urea and ferrocene. A preparation method of the low-temperature oxygen bleaching activator for the pure cotton fabric comprises the following steps: mixing the xylanase, urease, horseradish peroxidase, laccase and ferrocene to obtain a mixture, adding the carrier dispersion to the mixture, stirring and uniformly mixing the obtained mixture, carrying out vacuum freeze-drying, and crushing the dried mixture to obtain a dry powder; and stirring and mixing the obtained dry powder, the plant polyphenol and urea, and discharging the obtained material to obtain the low-temperature oxygen bleaching activator for the pure cotton fabric. Thelow-temperature oxygen bleaching activator for the pure cotton fabric, obtained in the invention, has an excellent bleaching effect.

Description

technical field [0001] The invention discloses an activator for low-temperature oxygen bleaching of pure cotton fabrics, which belongs to the technical field of textile auxiliaries. Background technique [0002] The pretreatment of traditional cotton fabrics mostly adopts high-temperature strong alkali scouring and bleaching process, which consumes a lot of water and energy, and discharges a large amount of pollutants; the strong alkalinity and high temperature during the treatment are easy to damage other fibers, which limits the use of Blending of other fibers; and when there is oxygen, the outermost layer of cellulose will be severely damaged, causing the loss of strength of the fabric. In order to save energy consumption in printing and dyeing, reduce wastewater discharge, and improve the quality of textiles, it is imperative to research and develop low-temperature and low-alkali pre-treatment processes. [0003] At present, oxygen bleaching activators mainly include te...
