Embodiment 1

[0035] The monomer that quality is shown in the monomer A (disperse blue 3G) shown in 136 grams formula (1), the monomer B (disperse violet B) shown in 110 grams formula (2), the monomer shown in 200 grams formula (3) Monomer D (dispersion yellow 5G) shown in C (dispersion golden orange G), 43 grams of formula (4), with 1000 grams of water, 121 grams of sodium lignosulfonate, 390 grams of MF diffusion agent together in a sand mill Grind for 6 hours, and then spray dry to obtain the powdered disperse dye product. The above-mentioned dye products can be dyed according to conventional methods, for example, take 0.5 grams of the above-mentioned powdered dye products, disperse them in 500 ml of water, then absorb 40 ml of dye liquid and mix them with 60 ml of water, adjust the dyeing bath to pH 5 with acetic acid, and heat up to 70 At the same time, put 5 grams of polyester textile materials for dyeing, heat up from 70°C to 130°C, keep warm for 45 minutes, cool to 80°C for sampling...

Abstract

A dark blue and black series disperse dye compound is formed by compounding three or four of a monomeric dye A, a monomeric dye B, a monomeric dye C, a monomeric dye D or a monomeric dye E, wherein the mass percents of the monomeric dye A, the monomeric dye B, monomeric dye C, the monomeric dye D and the monomeric dye E are respectively 18-45%, 15-50%, 0-50%, 0-20% and 0-45%. When the commercial disperse dye produced by the disperse dye compound of the invention is used for dying hydrophobic polyester fibers, polyurethane fibers, polyamide fibers, acetate fibers and the like, the dark blue or black dyed fabrics with beautiful color shade, good dispersibility, high upgrading force and excellent sun proofness, washability, friction resistance, perspiration resistance and the like can be obtained by adjusting the ratio of different dyes.

Description

technical field [0001] The invention relates to an environment-friendly dark blue and black series composite disperse dyes. Background technique [0002] With the rapid development of polyester fiber and other hydrophobic fibers and the improvement of people's demand for textiles. A series of compound disperse dyes with excellent dyeing performance and environmental protection requirements have been more and more widely used, but because some monomer dyes will crack under certain conditions to produce harmful aromatic amines, or cause human allergies, it is impossible to Meet the requirements of printing and dyeing textiles. It is a subject that we must solve to develop new compound disperse dyes with excellent dyeing performance in accordance with Oeko-Tex standard 100 by means of compounding. Contents of the invention [0003] The invention provides an environment-friendly composite dye of disperse black ECO, ECT, EX-NT series and disperse dark blue ECO series, which c...
