Preparation for degrading printing and dyeing pollution in natural fabric and preparation method of preparation

Abstract

The invention provides a preparation for degrading printing and dyeing pollution in a natural fabric. The preparation is prepared from, by weight, 10-20 parts of a citrus extract, 5-15 parts of a bacterium degradation preparation, 3-10 parts of maltose, 2-5 parts of betaine, 1-3 parts of baking soda, 2-5 parts of glucose oxidase, 1-3 parts of pectinase, 1-2 parts of cellulase, 2-5 parts of a metalchelating agent, 1-2 parts of tween-80, 1-2 parts of span-80 and 100-120 parts of deionized water. The glucose oxidase is separated from penicillium notatum, the pectinase is separated from aspergillus niger, and the cellulase is separated from basophilic bacteria. The preparation method of the preparation is simple, the raw material sources are wide, the cost is low, and the preparation has a good degradation effect on the printing and dyeing pollution of the natural fabric, is free of pollution, toxicity and harm, has fragrance and is popular among mass consumers.

Description

technical field [0001] The invention relates to the technical field of biological preparations, in particular to a preparation for degrading printing and dyeing pollution in natural fabrics. Background technique [0002] As we all know, the surface of cotton fiber contains pectin, wax and other hydrophobic substances. The traditional process mainly uses pretreatment measures such as high temperature and alkali scouring to remove these hydrophobic substances before dyeing. It is carried out in an independent process, the defects of its operation are very obvious, and the process is complicated. The pretreatment process of high temperature and alkali scouring needs to be carried out at 98°C-100°C, which requires a large amount of steam consumption, high energy consumption, long time, low efficiency, and high cost. In addition, the alkali scouring process requires the use of caustic soda , leading to the discharge of a large amount of alkaline waste liquid, increasing the pres...

The pretreatment process of high temperature and alkali scouring needs to be carried out at 98°C-100°C, which requires a large amount of steam consumption, high energy consumption, long time, low efficiency, and high cost. In addition, the alkali scouring process requires the use of caustic soda , leading to the discharge of a large amount of alkaline waste liquid, increasing the pressure of sewage treatment, polluting the environment, not environmentally friendly, and some components of the pretreatment agent will pollute the environment during the use process, and it is not easy to degrade and discharge after use. It brings a lot of trouble to fabric pretreatment, so we need a new type of energy-saving and environmentally friendly fabric pretreatment agent for printing and dyeing and its preparation method to solve the above problems and meet people's needs
