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 green dispersion dye composition and application thereof in wool dyeing. The green dispersion dye composition comprises the following components in percentage by mass: 30-50%of a component A of formula (I) as shown in the specification, 20-35% of a component B of formula (II) as shown in the specification, 15-25% of a component C of formula (III) as shown in the specification, 12-20% of a component D of formula (IV) as shown in the specification, and 3-5% of a component E of formula (IV) as shown in the specification. According the green dispersion dye composition, awool active dye monomer as the component E is mixed with other dispersed dye monomers, the component E has a modification function on other dispersed dye monomers in the dyeing process, the binding property of the dye composition with a wool fiber is greatly improved, and the dye composition has a relatively high dyeing rate for the wool fiber. A wool product dyed with the dye composition disclosed by the invention is green, is not only bright in color, but also good in uniform dyeing property, and has a relatively great market application prospect.

Description

technical field [0001] The invention belongs to the technical field of wool dyeing, in particular to a green disperse 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 morda...
