Problems solved by technology

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 blue BF 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 dyeing depth and reproducibility are average

Abstract

The invention discloses a composite reactive blue dye, which is characterized in that: the dye is formed by compounding, in parts by weight, 40 to 60 parts of dye shown as Formula (1), 30 to 40 parts of dye shown as Formula (2) and 10 to 20 parts of dye shown as Formula (3). The composite reactive blue dye has dyeing synchronicity and leveling property, high degree of fixation and prominent pile-on property, thereby overcoming the defects in similar dyes with reactive blue BF structure. The composite reactive blue dye of the invention is stable in properties, high in dissolubility and degree of fixation, good in dyeing synchronicity and leveling property and superior in color reproducibility, has the advantage of prominent pile-on property especially and is suitable for printing and dyeing cellulose fiber material.

Description

technical field [0001] The invention relates to the field of dyes, in particular to a composite reactive blue 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 blue BF are a kind of heterobiactive group (a chloro-s-triazine group and ethylene Sulfone-based) dyes, although it has higher color fastness to dyed fabrics after coloring cellulose fiber materials, but its dyeing depth and reproducibility are average. Contents of the invention [0003] The invention provides a composite reactive blue dye. The synergistic e...
