Problems solved by technology

[0004] Although reactive dyes for wool can solve the above problems, the price of reactive dyes is high, and the enterprise expenditure is relatively large, so it is difficult to popularize and use them.
[0005] Disperse dyes are cheap and have a similar structure to acid dyes, but they do not contain water-soluble ionic groups, so they have a certain affinity for wool. Although the wet fastness of wool dyed products has improved, it is still not ideal

Abstract

A blue violet disperse dye composition and applications thereof are disclosed. The composition includes, by mass, 40-60% of a component A shown as a formula (I), 20-35% of a component B shown as a formula (II), 18-30% of a component C shown as a formula (III) and 2-4% of a component D shown as a formula (IV). The component B and the component C have heterocyclic structures, and the heterocyclic structures are high in coloring intensity so that a dyed product has a bright color and excellent light fastness, sublimation fastness and discharging performance. The component B and the component C are synergistic and compounded to increase the dye uptake rate of the composition. The component D that is reactive dye for wool is mixed and used together with the components A, B and C, can modify disperse dye comprising the components A-B-C, and can greatly enhance bonding capability of the A-B-C and wool fibers, thus further increasing the dye uptake rate of the composition.

Description

technical field [0001] The invention belongs to the technical field of wool dyeing, and in particular relates to a blue-violet disperse dye composition and an application thereof. Background technique [0002] The dyes used for wool dyeing mainly include acid dyes, acid mordant dyes, reactive dyes and metal complex dyes. But above-mentioned dyestuff all has many problems in wool dyeing. [0003] Among them, level dyeing acid dyes generally cannot obtain good wet fastness due to containing water-soluble groups, and the dyed products are neither suitable for washing, nor bright in color. When acid mordant dyes are applied to wool fiber dyeing, dichromate is generally used as a mordant, and clothing products and dyeing wastewater dyed with acid mordant dyes will cause chromium residues in the waste treatment process, which will cause environmental pollution question. The "Green Ecolabel Agreement" adopted by the European Union in 2005 clearly stipulates the prohibition of ch...
