[0002] At present, the environmentally friendly black and blue series of disperse dyes on the market are generally composed of disperse orange 288#, disperse violet 93:1 and disperse blue 291:3. Although one of the components of this composition, disperse orange 288#, is an environmentally friendly dye, it makes up for The deficiency of Disperse Orange 76# is overcome, and the cost is much lower than that of Disperse Orange 61# which is also environmentally friendly. However, the disadvantages of Disperse Orange 288# are compatibility, dyeing depth

Embodiment 1～18

[0037] According to the data shown in Table 1, dye monomer A, dye monomer B, dye monomer C, dye monomer D are mixed with methylnaphthalenesulfonic acid formaldehyde condensate (dispersant MF), naphthalenesulfonic acid Formaldehyde condensate (diffusion agent NNO) and sodium lignosulfonate (lignin 85A, 83A) are blended with water, ground and dispersed with a sand mill, and then spray-dried.

[0038] Among them, (1-1) in dye monomer A can be selected from C.I.DISP BLUE 291 produced by Zhejiang Runtu Co., Ltd.: 1#; (1-2) can be selected from C.I.DISP BLUE 291 produced by Zhejiang Runtu Co., Ltd.: 2#; (1-3) is prepared by coupling 2,4-dinitroaniline chloride with 2-methoxy-5-acetamido-N-ethyl-N-allyl aniline; ( 1-4) is obtained by coupling 2,4-dinitroaniline chloride with 2-methoxy-5-acetamido-N-ethyl-N-cyanoethylaniline; (1-5) It is prepared by coupling 2,4-dinitroaniline chloride with diazotization and 2-methoxy-5-acetylamino-N-benzyl-N-cyanoethylaniline; (1-6) can be selected ...

Abstract

The invention discloses a black and blue disperse dye composition which comprises the components by weight percent: at least one 30-70% of dye monomer A shown in formula (1), at least one 15-40% of dye monomer B shown in formula (2), at least one 5-50% of dye monomer C shown in formula (3) and at least one 5-50% of dye monomer D shown in formula (4). The disperse dye composition has wide application scope of pH value, good compatibility, strong dye depth property, high color yield, good uniformity, and good sublimation fastness, washing fastness and fastness to sunlight; more importantly, the black and blue disperse dye composition has low price and convenient use, and makes up the defects of compatibility, dye depth property and tiger color of black and blue disperse dye spliced by disperse orange 288 model.

Description

technical field [0001] The invention relates to an environment-friendly black and blue disperse dye composition, which is suitable for dyeing and printing polyester and its blended fabrics. Background technique [0002] At present, the environmentally friendly black and blue series of disperse dyes on the market are generally composed of disperse orange 288#, disperse violet 93:1 and disperse blue 291:3. Although one of the components of this composition, disperse orange 288#, is an environmentally friendly dye, it makes up for The deficiency of Disperse Orange 76# is overcome, and the cost is much lower than that of Disperse Orange 61# which is also environmentally friendly. However, the disadvantages of Disperse Orange 288# are compatibility, dyeing depth, and hiding power, which are not as good as Disperse Orange 76# and Disperse Orange 61. #, and the yin color is relatively serious, and the high-grade imported polyester fiber with more yin color requirements can only be ...
