Problems solved by technology

[0002] In order to improve the quality of printing and dyeing products, in recent years, workers in the dye manufacturing industry and dye printing and dyeing industry have done a lot of experiments. It is always difficult to achieve good level dyeing and color yield by using a certain dye alone to dye and print textiles. The expected effect is high and the color reproducibility is good, but the dyeing and printing of textiles after mixing two similar dyes in a certain proportion can achieve very satisfactory results

Embodiment 1

[0068] Add 13.5 parts of cyanuric fluoride to 100 parts of ice / water and a small amount of silicone oil for ice grinding for 40 minutes, then add 34.1 parts of neutral 1-amino-8-naphthol-3.6-disulfonic acid in water for condensation reaction (this reaction The control conditions are T=14°C, pH=4) After 4 hours, add 28.1 parts of p-(β-hydroxyethylsulfone sulfate) aniline for the second condensation (the control conditions for this reaction are T=48°C, pH= 4) Until the reaction is complete (solution 1), dissolve 17.3 parts of 2-aminobenzenesulfonic acid in an aqueous solution of hydrochloric acid for beating for 1 hour, then cool down to 6.5°C with ice, and then add 30% sodium nitrite for diazotization 2 hours (solution 2), and finally add solution 2 to solution 1 in 50 minutes, and maintain T=15°C, pH=7 for coupling reaction, until no diazonium salt is detected, the reaction is complete, and the general formula can be obtained (1) The dye (1-1), which is capable of printing and...

Embodiment 2

[0071] Add 18.45 parts of cyanuric chloride to 100 parts of ice / water and a small amount of silicone oil for ice grinding for 40 minutes, then add 34.1 parts of neutral 1-amino-8-naphthol-3.6-disulfonic acid in water for condensation reaction (this reaction controls The conditions are T=14°C, pH=4) After 4 hours, add 28.1 parts of p-(β-hydroxyethylsulfone sulfate) aniline for the second condensation (the control conditions of this reaction are T=45°C, pH=4 ,) until the reaction was complete (solution three), 17.3 parts of 2-aminobenzenesulfonic acid was dissolved in an aqueous solution of hydrochloric acid for beating for 1 hour, then cooled to 6.5°C with ice, and then 30% sodium nitrite was added for diazotization 2 hours (solution 4), finally add solution 4 to solution 3 in 50 minutes, and maintain T=15°C, pH=7 for coupling reaction, until no diazonium salt is detected, the reaction is complete, and the general formula can be obtained (1) The dye (1-2), which can print and d...

Embodiment 3

[0074] Add 13.5 parts of cyanuric fluoride to 100 parts of ice / water and a small amount of silicone oil for ice grinding for 40 minutes, then add 34.1 parts of neutral 1-amino-8-naphthol-3.6-disulfonic acid in water for condensation reaction (this reaction The control conditions are T=14°C, pH=4) After 4 hours, add 36.1 parts of p-(β-hydroxyethylsulfone sulfate) aniline o-sulfonic acid for the second condensation (the control conditions for this reaction are T=48°C , pH=4) until the reaction was complete (solution five), 17.3 parts of 4-aminobenzenesulfonic acid was dissolved in an aqueous solution of hydrochloric acid for beating for 1 hour, then cooled to 6.5°C with ice, and then added 30% sodium nitrite for heavy Nitriding for 2 hours (solution 6), and finally adding solution 6 to solution 5 in 50 minutes, and maintaining T = 15 ° C, pH = 7 for coupling reaction, until no diazonium salt is detected, the reaction is complete, and you can get A dye (1-3) according to the gene...

technical field [0001] The invention relates to the field of dyes, which is an azo dye mixture. Background technique [0002] In order to improve the quality of printing and dyeing products, in recent years, workers in the dye manufacturing industry and dye printing and dyeing industry have done a lot of experiments. It is always difficult to achieve good level dyeing and color yield by using a certain dye alone to dye and print textiles. The expected effect is high and the color reproducibility is good, but the dyeing and printing of textiles after mixing two similar dyes in a certain proportion can achieve very satisfactory results. Contents of the invention [0003] The purpose of the present invention is to provide a mixture of azo dyes, which is easy to manufacture, cheap, and has significantly improved dyeing or printing effects compared with traditional single dyes, especially the color fastness and the reproducibility of color tone. The performance is more promine...
