Abstract

The invention discloses a multifunctional environment-friendly dyeing darkening agent, which comprises the following components in parts by weight: 2-5 parts of lignin, 6-10 parts of chitosan oligosaccharide, 3-8 parts of nano-silica sol, transglutamate 2-6 parts of amidase, 4-8 parts of sodium secondary alkyl sulfonate, 7-12 parts of fluoroacrylic emulsion, 2-4 parts of calcium sulfate, 1-3 parts of modified cyclodextrin, polyoxypropylene polyoxyethylene embedded 1-1.5 parts of segment copolymer, 2-3 parts of α-carboxyacetic acid, 1-3 parts of fluoroalkyl polyether modified polysiloxane, 20-30 parts of deionized water. The invention also discloses a preparation method of the multifunctional environmental-friendly dyeing darkening agent, which has a good darkening effect, can effectively reduce the amount of dye used, greatly improves the dye uptake rate of the dye, and has good compatibility with the dye. The treated fabric is soft and comfortable, bright in color and good in mechanical properties.

Description

Technical field: [0001] The invention relates to the field of textile auxiliaries, in particular to a multifunctional environment-friendly dyeing darkening agent. Background technique: [0002] In recent years, saving energy and reducing consumption is the primary task and breakthrough for adjusting my country's economic structure. The printing and dyeing industry consumes a lot of water, ranking second in the national manufacturing industry, and has a large amount of wastewater discharge, but the water reuse rate is only 7%. The cost of energy consumption, water consumption and sewage discharge in the whole dyeing and finishing process is relatively large. Cotton and silk fibers are dyed with reactive dyes, plus washing, descouring and bleaching processes, which consume more water and waste water. [0003] The main substances in the dyeing wastewater of printing and dyeing factories are dyes and auxiliaries. On the premise of maintaining the dyeing depth of printing and d...
