Embodiment 1

[0072] The preparation of embodiment 1 anthraquinone dye I

[0073] In a 1000 ml beaker, add 100 parts of crushed ice, 50 parts of water, 18.5 parts of cyanuric chloride, 0.1 part of dispersant, stir for 30 to 45 minutes, add 53.2 parts of the dye matrix of general formula I, at pH=5.5~ 6.5. React at a temperature of 8-12°C for 3 hours. After reaching the end point, add 17.3 parts of m-aminobenzenesulfonic acid, raise the temperature to 40-45°C, adjust the pH to 7-7.5 with sodium carbonate, and react for 6 hours. After the pH is stable, it will be At the end point, directly spray dry to obtain the dye I-1.

[0074]

Embodiment 2-5

[0075] The preparation of embodiment 2-5 anthraquinone dyes I-2~I-5

[0076] Compared with Example 1, the only difference is that the m-aminobenzenesulfonic acid in the reaction process is replaced by p-aminobenzenesulfonic acid, anthranilolsulfonic acid, etc., and dyes I-2 to I-5 can be obtained respectively.

[0077]

[0078]

[0079] Only some dyes shown in general formula I have been exemplified here, and those skilled in the art can foresee that different reactants can be used to obtain dyes I with different substituents to finally realize the present invention. repeat.

Embodiment 6-10

[0080] The preparation of embodiment 6-10 anthraquinone dye II

[0081] In a similar manner to Example 1, the dye precursors of general formula II were used to replace the dye precursors of general formula I to obtain dyes II-1 to II-5.

[0082]

[0083]

[0084] Only some dyes of the general formula II are exemplified here. Those skilled in the art can foresee that different reactants can be used to obtain dyes II with different substituents to finally realize the present invention.

Abstract

The invention discloses a high-performance anthraquinone cobalt blue mixed reactive printing dye, including anthraquinone type dyes as shown in a formula I and a formula II and a scattered solubiliser as shown in a formula III. The reactive printing dye can be applied for printing on cellulosic fibers of cotton and hemp or protein fibers of wool and silk, presents brilliant red light blue, has fixation rate, washing and sweat resistance wet-processing fastness and sunlight fastness, also has very high solubility and dissolving speed, can be used without water dissolving, can be prepared into a dye printing slurry by the powder, and has no colored spot phenomenon.

Description

technical field [0001] The invention relates to a printing dye, in particular to a high-performance anthraquinone type brilliant blue mixed reactive printing dye. Background technique [0002] Reactive dyes, also known as reactive dyes. It is a class of dyes that chemically react with fibers during dyeing. Such dye molecules contain groups that can chemically react with fibers. When dyeing, the dyes react with the fibers and form covalent bonds between them to form a whole, which improves the fastness to washing and rubbing. Reactive dyes are a new class of dyes. [0003] Reactive dyes are composed of parent dyes, linking groups and active groups, so that they can form a strong covalent bond with the fiber when used, and have a series of characteristics that other cellulose fiber dyes cannot match, and establish it as a fiber dye. The key position of the development and use of dyes for plain fibers is prominently reflected in the following four aspects: [0004] (1) Reac...
