Problems solved by technology

Non-ionic surfactants have little effect on cellulase activity, but their ability to inhibit restaining is also weak. Therefore, conventional surfactants are less effective as anti-restaining agents for enzymatic washing of denim garments

Abstract

The invention discloses a staining back-preventive agent of jean clothes, and a preparation method thereof, and in particular relates to a method for synthesizing a macromolecular staining inhibitor through ternary polymerization. The method comprises the steps of: synthesizing N-vinyl pyrrolidone, fumaric acid and acrylic acid into a ternary copolymer through adopting a solution polymerization method, then adding higher alcohol into a reaction system, and carrying out esterification reaction under the action of an acid catalyst to obtain ester-containing high polymer as the staining inhibitor. The staining inhibitor is compounded together with polyoxyethylene ether and a polyxyethylene amine product non-ionic surfactant to obtain an enzyme washed staining back-preventive agent. The staining back-preventive agent not only can improve the enzyme washing effect, but also can effectively prevent the staining back.

Description

technical field [0001] The invention relates to a surfactant for textile dyeing and finishing, in particular to a preparation process of an anti-restaining agent system for enzymatic washing of denim garments, and belongs to the technical field of textile auxiliaries and fine chemicals. Background technique [0002] Denim clothing has become a casual clothing favored by modern people due to its unique wearing performance. Over the years, the unique charm of wear-resistant, crisp and comfortable denim clothing has made it enduring in the international clothing market. The finishing process of denim clothing is the key process to make denim have a unique style. Old-fashioned finishing is an important processing technology in the process of denim garment processing, and it is an important content to measure the appearance quality of denim. For a long time, the old-fashioned appearance of denim clothing has been mainly obtained by stone-washing to strip off part of the indigo ...
