Embodiment 1～9

[0027] According to the proportion method in Table 1, the dye monomer A, dye monomer B, dye monomer C and co-solvent are mixed. The commonly used monomer powder blending method in this industry can be used. The powder blending needs to ensure The lower material is returned to the upper port three times, and the total mixing time is 3 hours. The above mixing methods are sampled from the top, middle and bottom of the container respectively, and the difference in depth is required to be no more than 2%.

Abstract

The invention discloses a preparation method of a grey dye. The method is as follows: dye compositions are mixed; the dye compositions comprise the following components: 80% to 96% by mass of a dye monomer A shown as a formula (1), 2% to 9% by mass of a dye monomer B shown as a formula (2) and 2% to 11% by mass of a dye monomer C shown as a formula (3), the total mass of the dye compositions is 100%; R1 and R2 are independently H or-SO3Na, and R1 and R2 are not the same. The dye obtained by the preparation method is a composite grey dye, has the advantages of excellent dyeing process stability, good color fastness, high dyeing levelness, and easy water washability.

Description

technical field [0001] The invention relates to a preparation method of gray dye. Background technique [0002] The active gray varieties currently on the market usually use black 8 monomer. When it is used for color matching in the printing process, from the perspective of process conditions, steaming time, temperature, and humidity have a greater impact on shade and depth, causing factories The quality of printed cloth samples is reduced and downshifted, and even defective products appear in severe cases. The compound product has low process sensitivity, stable hue and depth under different process conditions, and can significantly improve factory production efficiency and product color accuracy. [0003] In addition, with the improvement of living standards, people's requirements for textile products are also getting higher and higher, so that the requirements for various properties of reactive dyes used in textile dyeing are becoming increasingly stringent. Reactive dy...
