Embodiment 1～9

[0026] According to the ratio method in Table 1, the dye monomer A, dye monomer B, dye monomer C and co-solvent can be mixed. The monomer powder blending method commonly used in this industry can be used, and powder blending needs to be guaranteed The bottom material is returned to the top three times, and the total mixing time is 3 hours. The above mixing methods are all sampled and tested from the top, middle and bottom of the container, and the depth difference is required to not exceed 2%;

Abstract

The invention discloses a gray dye, a dye composition and application of the gray dye. The gray dye provided by the invention is prepared from the following components: 80 to 96 percent of a dye monomer A as shown in formula (1), 2 to 9 percent of a dye monomer B as shown in formula (2) and 2 to 11 percent of a dye monomer C as shown in formula (3), wherein the percentage is mass percentage of the dye composition; the total percentage of the dye composition is 100 percent; R1 and R2 are independently H or SO3Na, and are different. The dye prepared from the dye composition is a composite gray dye which is excellent in dye process stability, high in color fastness, high in leveling property and washable.

Description

Technical field [0001] The invention relates to a gray dye, a dye composition and applications thereof. Background technique [0002] At present, the reactive gray varieties on the market usually use black 8 monomer. When it is used in the color matching of the printing process, from the perspective of process conditions, steaming time, temperature, and humidity have a greater impact on shade and depth, resulting in factories The quality of printed fabric samples is reduced and downgrades, and in serious cases, defective products appear. This 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 have higher and higher requirements for textile products, so that the requirements for various properties of reactive dyes used in textile dyeing are becoming increasingly strict.
