Example Embodiment

[0037] Example 1

[0038] A disperse dark blue dye composition consisting of component A represented by structural formula (Ⅰ), component B represented by structural formula (II-1), component C represented by structural formula (III), and structural formula (IV) Component D, 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 additives.

[0041] The preparation method of the dispersed dark blue dye composition is as follows: after mixing components A to D according to a preset ratio, use a sand mill in the presence of the auxiliary agent (48% dispersant MF, 8% water) Or a pulverizing device such as a grinder is made into particles to obtain the dye composition.

Example Embodiment

[0042] Example 2

[0043] The disperse dark blue dye composition was prepared by the same method as in Example 1, but component B used the dye represented by the structural formula (II-2):

[0044]

[0045] The amount of each component remains unchanged.

Example Embodiment

[0051] Example 3

[0052] The disperse dark blue dye composition was prepared by the same method as in Example 2, but the dye with the following structural formula was selected as component C:

[0053]

[0054] The amount of each component remains unchanged.

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 ...
