Instant accelerating agent for reactive dye and application method of instant accelerating agent

Abstract

The invention belongs to the field of textile fabric dyeing, and particularly relates to an instant accelerating agent for a reactive dye and an application method of the instant accelerating agent. The instant accelerating agent comprises, by weight, 1-5 parts of sodium hydroxide, 2-3 parts of sodium carbonate, 0.5 part of polyvinylpyrrolidone, 1-5parts of potassium carbonate, 1-5 parts of sodium-2-naphthalene sulfonate, 1-5 parts of sodium gluconate, 4-8 parts of potassium sulphate, 25-40 parts of sodium chloride and 30-60 parts of sodium sulfate. Compared with the prior art, the instant accelerating agent and the application method have the advantages that a reasonable formula is utilized, so that the instant accelerating agent effectively replaces anhydrous sodium sulphate and sodium carbonate in use, the addition amount of inorganic salt is reduced and is 68-70% of the original usage amount, the product quality is improved, meanwhile, the production time is reduced, the cost is saved, the enterprise benefits are ensured, the content of the inorganic salt in dye-bath water is reduced, the number of times for after-treatment washing is reduced, the wastewater treatment degree is reduced, and the instant accelerating agent is suitable for large-scale application and popularization.

Description

technical field [0001] The invention belongs to the field of dyeing of textile fabrics, and in particular relates to an instant dyeing accelerator for reactive dyes and an application method thereof. Background technique [0002] Dyeing is dyeing, also known as coloring, which refers to the use of chemical or other methods to affect the substance itself to make it colored. Through dyeing, objects can be presented in various colors that people need, and colorful life can be used to decorate life. Textile materials are treated with a dye bath to chemically or physically combine dyes with fibers, or to generate insoluble colored substances on fibers. [0003] At present, in the printing and dyeing industry, the dyeing of cellulose fibers (loose fibers, yarns, gray cloths) is mostly dyed with reactive dyes, and it is necessary to add sodium sulfate and soda ash as dyeing aids during dyeing. The traditional process uses a lot, and the operator The labor intensity is high, and t...

Problems solved by technology

[0003] At present, in the printing and dyeing industry, the dyeing of cellulose fibers (loose fibers, yarns, gray cloths) is mostly dyed with reactive dyes, and it is necessary to add sodium sulfate and soda ash as dyeing aids during dyeing. The traditional process uses a lot, and the operator The labor intensity is high, and the sodium sulfate and soda ash dissolve slowly, and the whole process is time-consuming and power-consuming. At the same time, in the operation process, it is necessary to add materials in batches, the process is cumbersome, poor temperature control and poor batch processing may cause discoloration. Flowers and color difference lead to the need to use a large amount of inorganic salt treatment in the later stage, which increases the production cost and is not conducive to the growth and development of the enterprise
