Embodiment 1

[0030] After diazotizing 19.17 parts of 7-amino-1,3,6-trisulfonic acid-naphthalene by a known method, m-aminobenzene 7.56 parts of m-Aminophenyl urea are uniformly dispersed in 50 parts of water, then added to the above diazonium salt composition, and kept at a temperature of 8-10°C, with a pH value of 4.0, and then dispersed in ice water after the reaction is complete Add 9.22 parts of cyanuric chloride to the above solution, and keep it at a temperature of 5-8°C and a pH value of 5.0-5.5. After the reaction is complete, add 4-amino-2-(2-carboxyethyl)aminobenzenesulfonic acid 12.87 parts were added to the above reaction solution, and kept at a pH value of 6.0-6.5 at a temperature of 45°C, and the temperature was lowered to 7-10°C after the reaction was complete. Then 14.2 parts of 4-(2-sulfatoethylsulfonyl)aniline diazotized diazonium salt was added to the above solution, and the pH value was adjusted to 6.0, after the reaction was completed. The resulting solution is desalt...

Abstract

The invention discloses a golden yellow dye which is a reactive dye with industrial value for cellulose fibers. The golden yellow 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 yellow 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 suc...
