Problems solved by technology

The disadvantage of this type of dye is that it will change color with acid and alkali under different pH conditions, which will affect its application performance
At present, the domestic use of disperse dyes is large, but the variety is not rich, and the variety of fabric designs and colors continues to increase. More dyes with shades must be added to meet the needs of printing and dyeing factories. At the same time, polyester fabrics must be reduced by alk...

Embodiment 1

[0046] After 35 grams of formula (I-1) compound, 65 grams of formula (II-1) compound and 230 grams of dispersant MF are blended with 650 grams of water, they are ground, dispersed and dried to obtain the finished product. The dye can be provided to fabrics Yellow color with excellent fastness properties.

[0047]

Embodiment 2

[0049] With 30 grams of formula (I-1) compound, 55 grams of formula (II-1) compound, 15 grams of formula (III-1) compound and 250 grams of dispersant MF, after adding 650 grams of water, blending, grinding and dispersing and drying, The finished product is obtained. The dye can provide yellow color with excellent fastness properties to the fabric.

[0050]

Embodiment 3～25

[0052] According to the method described in embodiment 1 or 2, the difference is to adopt the structure and weight of components A~C in table 1, add 250 grams of auxiliary agents (dispersant MF is 200 grams, sodium lignosulfonate is 50 grams) , add 800 grams of water and blend to make a slurry, grind and disperse, dry, and make a finished product. The dye can provide a yellow hue with excellent fastness properties to the fabric.

Abstract

A disperse yellow dye composition, comprising component A and component B, the component A is selected from at least one of the following formula (I), and the component B is selected from the following formula (II) At least one of the components, based on the component A and component B, the mass percentage of component A is 5 to 95%, and the mass percentage of component B is 5 to 95%; in formula (I) : X1, X2 are each independently: hydrogen, halogen, nitro or -COOCH3; in formula (II): X3, X4 one of which is hydrogen and the other is nitro; R1 is C1~C4 alkyl; the present invention provides The disperse yellow dye composition and dye products of this product have the characteristics of good compatibility, good levelness, good pH dependence, excellent sublimation resistance and washing fastness when used in the dyeing of hydrophobic fiber materials;

Description

(1) Technical field [0001] The invention relates to a disperse yellow dye composition, in particular to an environment-friendly disperse yellow dye composition suitable for printing and dyeing hydrophobic fiber materials and its products. (2) Background technology [0002] There are many types of yellow disperse dyes, such as disazo-type disperse yellow 23, which is banned because it is easy to decompose the carcinogenic aromatic amine 4-aminoazobenzene; Good, it is suitable for many kinds of fibers, and the dyeing performance needs to be improved; the quinoline-based Disperse Yellow 54 has bright shades. In recent years, with the prohibition of Disperse Yellow 23, its usage is increasing. The above three disperse dyes can be colored under weak alkaline conditions, but are sensitive to strong alkali. [0003] In the face of huge market demand, various companies have launched alternative products one after another. So far, several commercial varieties have been commercialize...
