Embodiment 1

[0046] 1. The composition of the dye:

[0047] An environment-friendly alkali-resistant disperse red dye mixture, which is composed of two parts of dye and auxiliary agent, and the dye part is composed of 17 parts (mass parts) of C.I. Disperse Red 179 and 83 parts (mass parts) of C.I. Disperse Red 152 compositions. Then add sodium lignosulfonate according to the ratio of dye to dispersant 1:1.

[0048] 2. Preparation of dye mixture

[0049] According to the formula, the content of each dyestuff is converted into the weight of the original dyestuff wet filter cake and prepared. The wet filter cake of each raw dye is mixed with the diffusing agent sodium lignin sulfonate, sanded with water, and spray-dried to obtain the finished product.

Embodiment 2

[0050] Embodiment two: a kind of environment-friendly alkali-resistant type disperse red dye mixture

[0051] 1. The composition of the dye:

[0052] An environment-friendly alkali-resistant disperse red dye mixture, which is composed of two parts of dye and auxiliary agent, and the dye part is composed of 35 parts (mass parts) of C.I. Disperse Red 179 and 65 parts (mass parts) of C.I. Disperse Red 153 compositions. Then add sodium lignosulfonate according to the mass ratio of the dye part to the auxiliary agent part of 1:1.1.

[0053] 2, preparation method is the same as embodiment one

Embodiment 3

[0054] Embodiment three: a kind of environment-friendly alkali-resistant type disperse red dye mixture

Abstract

The invention discloses an environment-friendly alkali-resistant disperse red dye mixture, which is formed by mixing two parts of dyes and an auxiliary agent. The dye part consists of the following three dyes by mass percentage: the first is a dye which accords with a general chemical formula (I), wherein the content of the dye is 2.5 to 95 percent of the total weight of the dye part, and R is hydrogen, methyl or methoxyl in the formula (I); the second is a dye which accords with a general chemical formula (II), wherein the content of the dye is 2.5 to 95 percent of the total weight of the dye part, and R is the hydrogen or the methyl in the formula (II); and the third is a dye which accords with a general chemical formula (III), wherein the content of the dye is 2.5 to 95 percent of the total weight of the dye part, and R is the hydrogen or the methyl in the formula (III). A group of red dyes selected by the invention have consistent dyeing rate synchronism and alkali resistance, and have high accuracy rate of chromatic light when the dyeing is performed in a cylinder so as to solve the problems of redyeing and re-repair.

Description

technical field [0001] The invention relates to an environment-friendly alkali-resistant disperse red dye mixture, in particular to a medium-high temperature alkali-resistant disperse red dye mixture suitable for use in medium-dark dyeing of polyester fibers or fabrics, and belongs to the technical field of dyes. Background technique [0002] In order to obtain beautiful textiles, dyes are inevitably used in the textile processing industry. Disperse dyes are a type of non-ionic dyes that are dispersed in the initial stage of the dyeing process. The particle size is required to be around 1 μm. With the help of dispersants can be dispersed evenly in water. This kind of dye is mainly used for dyeing and printing of polyester and its blended fabrics, and has become the most important dye category in synthetic fiber dyes. With the development of polyester and its blended fabrics, the demand for disperse dyes will further increase in the future. Although my country's light texti...
