Disperse black dye composition

Abstract

The invention discloses a disperse black dye composition which comprises the following ingredients in parts by mass: 40-58 parts of an ingredient A, 23-29 parts of an ingredient B, 15-20 parts of an ingredient C, 12-18 parts of an ingredient D, 3-6 parts of an ingredient E and 5-8 parts of an ingredient F. The disperse black dye composition has the advantages of being stable in performance, high in solubility and color fixation rate, good in dyeing synchronization property, level dyeing property and hue reproduction property, and particularly outstanding in black color dyeing, and is particularly applicable to printing and dyeing cellulose fiber materials.

Description

technical field [0001] The invention relates to the field of dyes, in particular to a disperse deep black dye composition. 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 ...
