Embodiment 1

[0043] 37 grams of the dye component of formula (1), 53 grams of the dye component of formula (2-2), 10 grams of the dye component of formula (3-2), 100 grams of lignin 83A, and 300 grams of water are added and stirred evenly , grind, disperse and dry to obtain a black disperse dye, which has excellent fastness properties on polyester fiber dyed fabrics.

Embodiment 2-10

[0053] According to the composition formulation in Table 2, disperse dyes were made in the same manner as in Example 1. Wherein, the amount of moisture in Table 2 is the moisture weight of the final disperse dye.

[0054] Table 2

[0055]

[0056]

[0057] The method in Example 1 was used to test the sublimation fastness, color fastness to washing and perspiration fastness of the disperse dyes prepared in Examples 2-12, and the results are shown in Table 3.

Abstract

The invention discloses a dye composition and a disperse dye and its preparation method and application. The dye composition comprises a compound as shown in the formula (1) and at least one compound as shown in the formula (2) and formula (3). The disperse dye contains the disperse dye composition and an auxiliary material. The preparation method of the disperse dye comprises the following steps: mixing various dye components, and carrying out particlization treatment in the presence of the auxiliary material by a sand mill or a grinding machine; or respectively carrying out particlization treatment on the various dye components in the presence of the auxiliary agent by a sand mill or a grinding machine, and mixing. The prepared disperse dye is suitable for dyeing and printing of fabric, has good compatibility, is low-cost, has little pollution and is a disperse dye with good cost performance. In the formula (2), X1 is Br or Cl, and R1 is H or C2H5. In the formula (3), X2 is Cl or Br.

Description

technical field [0001] The invention relates to a disperse dye composition, a disperse dye and a preparation method and application thereof, belonging to the technical field of dyes. Background technique [0002] Blue-black series is the most widely used variety of dark disperse dyes. Most of them use C.I. Disperse Orange 288, C.I. Disperse Violet 93:1 or blending Disperse Violet 93 and C.I. Disperse Blue 291:1 to obtain blue-black series dispersions with excellent performance. dye. However, the sublimation fastness and washing fastness of such dyes still need to be improved. In the research, it was found that C.I. Disperse Blue 281 has good dyeing improvement properties, good sublimation fastness and washing fastness, and the by-product produced during the synthesis process, that is, the dye compound obtained after diazo coupling of the unethylated coupling component It also has good sublimation fastness and washing fastness. With the improvement of synthesis technology,...
