Embodiment 1

[0111] Add 59 grams of formula (Ia) component A, 36 grams of formula (II) component B, 5 grams of formula (IIIa) component C and 200 grams of methyl naphthalenesulfonic acid formaldehyde condensate (dispersant MF), add water After mixing, use a sand mill to grind and disperse to make a slurry, or further spray dry to make a blue disperse dye.

[0112]

Embodiment 2

[0128] Add 56 grams of formula (Ia) component A, 34 grams of formula (II) component B, 4.8 grams of formula (IIIa) component C, 5.2 grams of formula (Va) component E and 200 grams of lignin 85A, add water After mixing, use a sand mill to grind and disperse to form a slurry, or further spray dry to form a blue disperse dye.

[0129]

Embodiment 3-15

[0142] According to the method of Example 1 or Example 2, according to the raw materials provided in Table 3, add water and mix them, then grind and disperse them with a sand mill to prepare a slurry, or further perform spray drying to prepare a blue disperse dye.

Abstract

The invention discloses a disperse blue dye composition. The composition is basically prepared from one or more of a component A as shown in a formula (I), a component B as shown in a formula (II) and a component C as shown in a formula (III). Furthermore, a component D as shown in a formula (IV) and a component E as shown in a formula (V) can be selectively added into the disperse blue dye according to requirements. The invention further discloses a preparation method and an application of the composition. The disperse blue dye has the advantages of bright color, good sublimation fastness, good perspiration fastness, good light fastness and the like, the dye cost is relatively low, and pollution is relatively small.

Description

Technical field [0001] The invention belongs to the technical field of disperse dye preparation, and specifically relates to a disperse blue dye composition, a disperse dye and a preparation method thereof. The disperse dye is suitable for dyeing polyester and its blended fabric. Background technique [0002] As we all know, C.I. Disperse Blue 56 is recognized by printing and dyeing companies for its bright color, wide range of uses, and excellent lightfastness. However, there are still shortcomings of poor dye depth, poor sublimation fastness, and serious contamination of polyester cotton. [0003] To overcome these shortcomings, the patent document with the application number CN200610051792.0 discloses a disperse blue dye composition, which is basically composed of one or more dyes A as shown in formula (I), and one or more dyes as shown in formula (I). The composition of dye B shown in (II), one or more dyes C shown in formula (III) and auxiliary agents, based on dye A, dye B a...
