Embodiment 1～9

[0026] 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 upper, middle and lower parts of the container for inspection, and the difference in depth is required to be no more than 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] 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 s...
