Reactive dye accelerant and preparation method for same

Abstract

The invention discloses a reactive dye accelerant. The reactive dye accelerant is characterized by comprising, in parts by weight, 18-22 parts of granular sodium hydroxide, 9-13 parts of trisodium phosphate, 16-18 parts of tripotassium phosphate, 7-9 parts of sodium metasilicate, 40-55 parts of sodium carbonate, 5-10 parts of sodium lignin sulfonate, and 1-3 parts of an ionic liquid. The preparation method comprises the following steps of: pouring raw materials in a stirring kettle according to the proportion, stirring for 5-15 minutes at a speed of 20-40 r / min and in the condition of a temperature of 20-30 DEG C, and then obtaining the reactive dye accelerant. The reactive dye accelerant has the advantages of being capable of promoting the level dyeing of a reactive dye and increasing the colour yield of the reactive dye, thus improving the fastness of a dyed product and reducing the number of cleaning times of the dyed product, and beneficial to reduce the labour intensity of workers, reduce the cost of a dyeing process, and reduce pollution to environment; meanwhile, the reactive dye accelerant is convenient to dissolve, suitable for various reactive dyes and various equipment, and simple in preparation method.

Description

technical field [0001] The invention relates to an accelerator, in particular to a reactive dye accelerator and a preparation method thereof. Background technique [0002] With the increasing demand for composite fiber high-grade fabrics, the inapplicability of the traditional high-temperature dyeing technology with high energy consumption has become increasingly prominent. In recent years, low-temperature dyeing technology based on reactive dye accelerators has received widespread attention and has shown good application prospects. [0003] At present, the dyeing of cotton knitted fabrics with reactive dyes mainly relies on sodium hydroxide and soda ash to fix the color. These alkalis used for color fixing are called color fixing alkali. This kind of reactive dye dyeing technology has many disadvantages, mainly including backward process, many steps, complicated operation, etc., especially for the current conventional equipment, there are problems such as complicated proce...

AI Technical Summary

Problems solved by technology

In the existing technology, some people use substitute alkali as reactive dye accelerator to improve the dispersibility of reactive dyes. However, compared with soda ash, substitute alkali only reduces the amount of water, and cannot solve the fundamental problem

In similar studies, many scholars have studied some other new reactive dye accelerators and their production processes. The reactive dye accelerators produced are not only non-toxic and environmentally friendly, but also save labor and time, and comprehensively improve the yield of processed products. , however there is still the problem of level dyeing of reactive dyes
