Problems solved by technology

[0003] For a long time, when carrying out the medium and deep color dyeing process containing Cuilan reactive dyes, although the process operation, such as using chelating dispersant, adding salt and alkali in multiple steps, and extremely slow heating rate, etc., the method of color flower chances are still high
For this reason, it needs to be stripped and back dyed. After returning to water, it still faces this problem and the fastness is not good.
After analysis, it is believed that the molecular weight of the green blue dye is very large, which leads to fast coloring, but the fastness is poor, and the washing water is not clean.

Abstract

The invention discloses a dyeing technology of bright blue-containing reactive dye. The technology includes the following steps: 1, scouring and bleaching: sequentially adding 1g / L of a stabilizer, 3.5g / L of soda ash, 0.35g / L of a non-foam detergent agent, 2.0g / L of a wrinkle resistant agent CD and 6g / L of hydrogen peroxide at 40DEG C, and heating to 90DEG C, wherein the time is 60min, and a bath ratio is 1:10; and 2, dyeing: dyeing by using 3g / L of active bright blue B-BGFN, 1.43g / L of active bright yellow B-4GLN, 0.95g / L of active golden yellow B-4RNF, 80g / L of sodium sulfate, 25g / L of soda ash, 2g / L of a leveling agent RG-133 and 1g / L of a dispersant EXL-106, wherein a bath ratio is 1:10. The dyeing technology has the advantages of simplicity, practicality, difficult fading, improvement of the dyeing defect problem of grey cloth, and obvious fastness improvement.

Description

technical field [0001] The invention particularly relates to a dyeing process containing turquoise blue reactive dyes. Background technique [0002] Dyeing is a very old craft. Judging from the unearthed cultural relics, my country, India, and Egypt knew to use certain natural dyes for dyeing as early as prehistoric. Since Perkin invented synthetic dyes in 1856, people have successively studied the dyeing principles of dyes, but many basic researches that are more effective are after the First World War, when cuprammonium fibers, viscose fibers and acetate fibers came out. After the Second World War, all kinds of synthetic fibers continued to appear. [0003] For a long time, when carrying out the medium and deep color dyeing process containing Cuilan reactive dyes, although the process operation, such as using chelating dispersant, adding salt and alkali in multiple steps, and extremely slow heating rate, etc., the method of color flower The odds are still high. For thi...
