Embodiment 1

[0030] Disperse 8.75 parts of cyanuric chloride in 50 parts of ice-water mixture, then dissolve 12.14 parts of 4-amino-2-(2-carboxyethyl)aminobenzenesulfonic acid in 70 parts of water, and add the above solution under stirring , and then kept stirring for 60 minutes at 5-8°C, pH 6.0-6.5. In addition, dissolve 12.14 parts of 4-amino-2-(2-carboxyethyl)aminobenzenesulfonic acid in 70 parts of water, then add it to the above solution, and raise the temperature to 40°C, keep the pH=6.0-6.5 and stir until the reaction is complete , and then at a temperature of 5-10 ° C, 26.76 parts of 4-(2-sulfatoethylsulfonyl) aniline diazotized diazonium salt in a known method are added to the above solution, and the pH value is adjusted To 6.0, after the end of the reaction. The resulting solution is desalted and dried to obtain a golden dye of the formula, λ max =435nm, golden dyes with excellent characteristics can be obtained after dyeing.

Abstract

The invention discloses a golden dye which is a reactive dye with industrial value for cellulose fibers. The golden dye has the advantages of excellent color fixation capacity, excellent deep dyeing property and high absorption cleaning capacity, and is suitable for dyeing within a wide temperature range.

Description

technical field [0001] The invention relates to a dye, in particular to a golden dye. Background technique [0002] Dyes are substances that can color fibers and other materials, and are divided into two categories: natural and synthetic. Dyes are colored substances. But a colored substance is not necessarily a dye. As a dye, it must be able to attach a certain color to the fiber without falling off or changing color. In 1856, Perkin invented the first synthetic dye - horsetail violet, which made organic chemistry a new discipline - dye chemistry. 1950s. Pattee and Stephen discovered that dyes containing dichloro-s-triazine groups bonded to hydroxyl groups on fibers under alkaline conditions, which marked the development of dyes from physical processes to chemical processes in fiber coloring, and created a period for the synthesis and application of reactive dyes . Dyes are not limited to the dyeing and printing of textiles, they are used in many departments such as pa...
