Problems solved by technology

[0006] The above two prominent contradictions directly lead to the asynchronous dyeing time when reactive red 3BS and reactive orange 82 are combined to dye cellulose fiber materials, resulting in poor shade reproducibility and high color flower rate

Abstract

The invention relates to a composite reactive red dye which is characterized by compositing 50-80 parts of dye shown in the formula (1), 10-20 parts of dye shown in the formula (2) and 10-30 parts of dye shown in the formula (3), wherein in the formula (1), the formula (2) and the formula (3), R1 is -H, -OCH3 or -CH3, R2 is one of the following formulas, and M is an alkali metal atom. The composite reactive red dye of the invention has stable performance, high solubility, high color fixing rate, good dyeing synchronism, good level-dyeing property and good color reproducibility, and is suitable for printing and dyeing cellulose fiber materials.

Description

technical field [0001] The invention relates to the field of dyes, in particular to a composite reactive red dye. Background technique [0002] With the continuous development of cellulose fiber varieties and the continuous development of dyeing technology, when using reactive dyes to dye cellulose fibers, higher and higher requirements are put forward for the application performance of reactive dyes. Due to the coloring of fiber materials by single-color dyes, the comprehensive value of various performance indicators is difficult to achieve satisfactory results. For example, dyes with a structure similar to reactive red 3BS are a kind of heterobiactive group (a chloro-s-triazine group and ethylene Sulfone-based) dyes, although it has high color fastness to dyed fabrics after coloring cellulose fiber materials, but its level dyeing and reproducibility are average, so the compound application of two or more dyes is better It has received more and more attention and attention...
