Embodiment 1～18

[0039] According to the data shown in Table 1, the dye component A, dye component B, dye component C and auxiliary agents (dispersant MF, diffusing agent NNO, diffusing agent CNF, lignin 83A, lignin 85A) were mixed with water Finally, grind and disperse with a sand mill, and then spray dry.

[0040] Among them, in component A:

[0041] Formula (I-1) can adopt the disperse blue 291:1 that Zhejiang Runtu Co., Ltd. produces;

[0042] Formula (I-2) can adopt the disperse blue 291:2 that Zhejiang Runtu Co., Ltd. produces;

[0043] Formula (I-3) can adopt the disperse blue 291# that Zhejiang Runtu Co., Ltd. produces;

[0044] Formula (I-4) can adopt the disperse blue modification 291# that Zhejiang Runtu Co., Ltd. produces;

[0045] Formula (I-5) can adopt the disperse blue 79:1 that Zhejiang Runtu Co., Ltd. produces;

[0046] Formula (I-6) can adopt the disperse blue 79# that Zhejiang Runtu Co., Ltd. produces;

Abstract

The invention discloses a black-blue disperse dye composition, which comprises the following components in percentage by weight: 53 to 91 percent of component A, 5 to 46 percent of component B and 0 to 5 percent of component C, wherein the component A is one or more of components expressed in a formula (I), the component B is one or more of components expressed in a formula (II), and the component C is one or more of components expressed in a formula (III). The black-blue disperse dye composition has the advantages of good compatibility, good coverage, high dyeing rate, good dyeing depth and excellent fastnesses such as sunlight resistant fastness, friction resistant fastness, sublimation resistant fastness and the like, and particularly the washing fastness is obviously improved; and the composition is convenient to use and has good market prospect.

Description

technical field [0001] The invention belongs to the field of disperse dye preparation, in particular to a black and blue disperse dye composition which is especially suitable for dyeing and printing of polyester and its blended fabrics. Background technique [0002] With the continuous improvement of people's living standards, the requirements for textiles are also increasing day by day, thus putting forward higher requirements for dyes used in printing and dyeing. In the printing and dyeing industry, disperse dyes are one of the most widely used product categories. Among the disperse dyes, the dark dyes are mainly black and blue. If this kind of dark dye adopts a single structure, its dyeing depth will be greatly reduced. For this reason, most black and blue disperse dyes are mainly blended. . Currently, the blended black and blue disperse dyes in the market are single in variety and have certain defects in application performance. Therefore, the printing and dyeing indu...
