Embodiment l

[0031] Mix 7 grams of formula (I-1), 93 grams of formula (II-1), 250 grams of dispersant MF, add 200 grams of water, grind and disperse, and dry to obtain disperse golden yellow dye.

Embodiment 2

[0033] Mix 45 grams of formula (I-2), 30 grams of formula (I-3), 25 grams of formula (II-1), 250 grams of diffusing agent NNO, and add 300 grams of water, grind and disperse, and dry to obtain disperse orange dye.

Embodiment 3～20

[0035] According to the method described in Example 1, the difference is that the weight ratio of component A, component B and auxiliary agents in Table 1 are used, and the slurry is made after adding water and blending, and it is advisable to control the solid content of the slurry to 35-45%. , grind and disperse, and dry to obtain disperse yellow to orange dyes, which are suitable for one-bath, one-step dyeing of polyester fibers and their blended fabrics under alkaline conditions for pretreatment and dyeing.

Abstract

The invention relates to a disperse yellow and disperse orange dye composition, which is prepared by mixing and blending raw dyes and assistant agents, wherein the raw dyes comprise 1-99 wt% of a component A and 1-99 wt% of a component B, the component A is one or a plurality of materials selected from compounds represented by a formula (I), and the component B is one or a plurality of materials selected from compounds represented by a formula (II), wherein in the formula (I), R1 and R2 are simultaneously hydrogen or are independently Cl or Br, R3 is hydrogen, C1-C4 alkyl, C1-C4 alkoxy or Cl, R4 is cyanoethyl or C1-C4 alkyl, m is 1 or 2, and R1 and R2 are simultaneously H when m is 1, and in the formula (II), R5 is H, CH3, Cl or Br, R6 is H, Cl or Br, R7 is Cl or CH3, R8 is C1-C4 alkyl or cyanoethyl, and n is 1 or 2. The dye composition of the present invention has advantages of excellent fastnesses and good pH value dependence. The formula (I) and the formula (II) are represented in the instruction.

Description

(1) Technical field [0001] The invention relates to a class of disperse dye compositions, in particular to a class of disperse yellow to orange dye compositions suitable for dyeing in a wide pH range. (2) Background technology [0002] In the traditional polyester fabric dyeing and finishing process, pretreatment desizing, refining (including relaxation) and alkali reduction processes are carried out under alkaline conditions, while disperse dyeing is carried out in an acid bath. Due to the precipitation of unwashed slurry, oil and other decomposition products in the acid bath, many stains are caused. Therefore, the basic dyeing method with disperse dyes was developed in the mid-1980s. Although the basic dyeing method of disperse dyes has considerable advantages in terms of process rationalization and improvement of dyeing quality. However, the expected effect was not achieved at the initial stage of development, the main reason being that it affected the dyeing performanc...
