Abstract

The invention discloses a multi-functional pretreatment refining agent. The multi-functional pretreatment refining agent comprises, by weight, 30 to 60 parts of a natural nonionic surfactant, 10 to 30 parts of a nonionic mixture, 20 to 40 parts of an acrylic acid-hydroxyethyl acrylate copolymer and 10 to 30 parts of clay. The natural nonionic surfactant has effects of removing oil and wax, carrying out emulsification and easily degrading organisms and is environmentally friendly. Through use of the nonionic mixture comprising nonionic substances, activity of an enzyme in enzyme refining is not reduced and can be improved. Through use of the acrylic acid-hydroxyethyl acrylate copolymer, metal ions such as calcium and magnesium are chelated and activity of the enzyme is not influenced. Through use of clay, the multi-functional pretreatment refining agent has an excellent oil emulsification capacity, waste water COD is reduced, an oil emulsification capacity is high and easy degradation and environmental friendliness are obtained.

Description

technical field [0001] The invention relates to the field of textile auxiliaries, in particular to a multifunctional pretreatment refining agent. Background technique [0002] The pretreatment of fabrics in the textile industry generally includes desizing, refining and bleaching processes. Refining is a very important process in the pretreatment process of pure cotton fabrics and their blended fabrics. Its main purpose is to remove symbiotics in cotton fibers. Unrefined cotton fiber contains cellulose, pectin, waxy substances, nitrogenous substances, lignin, etc. During the refining process, firstly, under the action of refining agent, the refining liquid and other chemical substances penetrate into the fiber, and secondly, in the fiber After fully wetting, various impurities on the fiber are removed by saponification, emulsification, extraction, dispersion, etc. The impurities are detached from the fibers under mechanical action and dispersed in the solution. [0003] Not...
