Abstract

The invention provides an environment-friendly multifunctional scouring agent and a preparation method thereof. The environment-friendly multifunctional scouring agent contains no banned substances such as alkylphenol polyoxyethylene or adsorbable organic halides, etc., is easy to dissolve in water, is resistant to acid, alkali and hard water, is low-foam, and is convenient to use. By integratingpenetration, emulsification, chelating, dispersion and hydrogen peroxide stabilization through the environment-friendly multifunctional scouring agent, pretreatment process is simplified, rationalizedand economized, and is energy-saving and environmentally-friendly. The environment-friendly multifunctional scouring agent is of great revolutionary significance for a traditional process, is widelyapplicable to cotton and blended fabrics process, can be used for conventional desizing, boiling and bleaching process as well as short-process cold batching process, and can achieve good desizing rate, whiteness and capillary effect. In addition, the environment-friendly multifunctional scouring agent also has chelating ability, can chelate metal ions in work bath, prevent the influence of metalions on pretreatment and dyeing, and is helpful for raising product quality.

Description

technical field [0001] The invention relates to an environment-friendly multifunctional scouring agent and a preparation method in the technical field of textile printing and dyeing. Background technique [0002] Scouring is a very important process in the pretreatment process of printing and dyeing. The purpose is to remove impurities contained in cotton fibers, such as cotton seed hulls, cotton wax, pectin, protein, unremoved size in the desizing process, and stained fabrics. Oil stains, etc. In the past 20 years, with the popularization of high-efficiency short-process pretreatment processes such as alkali-oxygen-bath and cold pad batch, increasing scouring speed, saving energy consumption, reducing water consumption, and shortening the process flow have become urgent problems to be solved. It is necessary to seek rapid penetration , strong emulsifying power, strong chelating ability, high detergency, high temperature resistance, concentrated alkali resistance, hard wate...
