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

The invention discloses a black dye composition and application of the black dye composition in wool dyeing. The black dye composition comprises 30-50% of a component A which is shown in a formula (I), 30-50% of a component B which is shown in a formula (II), 1-15% of a component C which is shown in a formula (III), 1-15% of a component D which is shown in a formula (IV) and 1-10% of a component Ewhich is shown in a formula (IV). According to the black dye composition and application of the black dye composition in wool dyeing, the reactive dye (the component E) is mixed with a disperse dye so as to obtain the dye composition which takes the disperse dye as the main component and the reactive dye as the assistant component; and not only can the dye composition have good wet fastness and strong color fastness, but also the binding ability of the dye composition and wool fiber can be enhanced greatly since the component E has a modifying effect on other disperse dye monomers, so that the dye composition has high dye-uptake to the wool fiber.

Description

technical field [0001] The invention belongs to the technical field of wool dyeing, and in particular relates to a black dye composition and its application in wool dyeing. 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 chrome mo...
