Embodiment 1

[0038] A disperse dark blue dye composition, which is represented by component A shown in structural formula (I), component B shown in structural formula (II-1), component C shown in structural formula (III), and structural formula (IV) Component D and dispersant and water composition:

[0039]

[0040] In terms of mass fraction, the mass fraction of component A is 14%, the mass fraction of component B is 26%, the mass fraction of component C is 2%, the mass fraction of component D is 2%, and the rest are auxiliary agents.

[0041] The preparation method of the disperse dark blue dye composition is: after mixing the components A to D according to the preset ratio, use a sand mill in the presence of auxiliary agents (48% dispersant MF, 8% water content) or a pulverizing device such as a mill to obtain the dye composition.

Embodiment 2

[0043] Adopt the method identical with embodiment 1 to prepare disperse dark blue dye composition, but component B adopts structural formula to be the dyestuff shown in (II-2):

[0044]

[0045] The amount of each component was not changed.

Embodiment 3

[0052] Adopt the same method as embodiment 2 to prepare disperse dark blue dye composition, but choose the dyestuff with following structural formula as component C:

[0053]

[0054] The amount of each component was not changed.

Abstract

The invention discloses a dispersive dark blue dye composition which consists of by mass percent, 5-25% of a component A shown by a structural formula (I), 10-40%of a component B shown by a structural formula (II), 1-10% of a component C shown by a structural formula (III), 1-10% of a component D shown by a structural formula (IV) and the balance of an auxiliary agent. A piece of sample cloth dyed by the dye composition disclosed by the invention is bright in color, has excellent washing-resistance fastness, rubbing-resistance fastness, sweat stain resistance fastness, daylight-resistance fastness and high degree of dyeing, and the production cost of the dye composition is low.

Description

technical field [0001] The invention relates to a disperse dye, in particular to a disperse dark blue dye composition. Background technique [0002] After entering the 21st century, the competition in the world's textile market has become increasingly fierce. Southeast Asia's economy has become synonymous with low cost and high growth, and the textile industry business in Europe and the United States has also accelerated its transfer to Asia. In order to adapt to the situation of fierce competition in the textile market, it has become the common goal of textile enterprises to continuously reduce the production cost of textiles, continuously improve product quality, and continuously reduce environmental loads. [0003] Disperse dyes have very low solubility in water, very fine particles, and are dispersed in the dye solution. They are non-ionic dyes and are mainly used for polyester dyeing with high color fastness. For example, the Chinese patent with the publication number ...
