Embodiment 1

[0111] With 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 methylnaphthalenesulfonic 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] Component A of 56 grams of formula (Ia), 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 make a slurry, or further spray dry to make 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, after adding water and blending, grind and disperse with a sand mill to make a slurry, or further spray dry to make 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 in particular 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 fabrics. Background technique [0002] As we all know, C.I. Disperse Blue 56 is recognized by printing and dyeing enterprises for its bright shade, wide application and excellent light fastness. However, there are still disadvantages of poor dyeing depth, poor sublimation fastness, and serious staining of polyester and cotton. [0003] For overcoming these shortcoming, application number is that the patent document of CN200610051792.0 discloses a kind of disperse blue dye compsn, substantially by one or more dyestuffs A as shown in formula (I), one or more such as formula 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 and dye C...
