Embodiment 1～18

[0035] According to the data in Table 1, the dye monomer A, dye monomer B, dye monomer C, auxiliary agent and water were mixed, ground and dispersed with a sand mill, and then spray-dried. The dye monomers can be commercially available or self-prepared.

[0036] The preparation method of the structural formula (1-1) is as follows: after diazotization of 2,6-dibromo-4 nitroaniline, it is then coupled with N-butyl-N-cyanoethylaniline.

[0037] The preparation method of the structural formula (1-2) is as follows: after diazotization of 2-chloro-6 bromo-4 nitroaniline, it is then coupled with N-butyl-N-cyanoethylaniline.

[0038] The preparation method of structural formula (1-3) is as follows: after diazotization of 2-chloro-6 bromo-4 nitroaniline, and then coupling with N-methyl-N-cyanoethylaniline.

[0039] The preparation method of structural formula (1-4) is as follows: after diazotization of 2,6-dibromo-4 nitroaniline, and then coupling with N-methyl-N-cyanoethylaniline.

Abstract

The invention discloses a moderate-temperature environment-friendly disperse orange dye, which comprises a dye monomer A as shown by the formula (1) and accounting for 10 to 50 percent; a dye monomer B as shown by the formula (2) and accounting for 8 to 45 percent; and an accessory ingredient accounting for the rest. The disperse orange dye can further comprise a dye monomer C as shown by formula (3) and accounting for 0.01 to 2 percent. The environment-friendly dye disclosed by the invention can substitute for the mixing color of No.30 C.I.DISP.ORANGE in black and blue of 300 percent, and can be applied in wide PH values when used for dyeing with high build-up, high color yield, excellent level-dyeing property and overall firmness.

Description

technical field [0001] The invention relates to a medium-temperature environment-friendly disperse orange dye, which is especially suitable for dyeing and printing polyester and its blended fabrics. Background technique [0002] Disperse dyes are mainly used for dyeing and printing of polyester fibers. At present, with the rapid development of polyester fibers, higher requirements are put forward for the performance of disperse dyes: firstly, they must be environmentally friendly dyes, and secondly, they must be heat-resistant migration and various dyes. All fastness indicators must be excellent, and the compatibility between dyes is good. Patents EP0491386, JP10251534, and JP08100132 are all dye blending applications, the purpose of which is to improve the printing and dyeing performance of dyes. However, judging from the existing varieties of azo stitching dyes, they still cannot meet the demand in terms of application performance such as lifting power and color fastness....
