Embodiment 1

[0039] Component A of 50 grams of formula (I-1), component B of 50 grams of formula (II-1), and sodium lignosulfonate of 150 grams are mixed with water and then ground and dispersed with a grinder and dried. A finished dye is obtained, which can provide a bright red color to the fabric with uniformity and good fastness properties.

Embodiment 2

[0041]Component A of 35 grams of formula (I-1), component B of 50 grams of formula (II-1), component C of 15 grams of formula (III-1), sodium lignosulfonate of 200 grams, add water After blending, use a grinder to grind, disperse and dry to obtain the finished product. This dye can provide bright red color to fabrics with good fastness.

Embodiment 3

[0043] Component A of 50 grams of formula (I-1), component B of 45 grams of formula (II-1), component D of 5 grams of formula (IV-1), sodium lignosulfonate of 180 grams, add water After blending, use a grinder to grind and disperse, and dry to obtain the finished product. The dye can provide bright red color to fabrics with good fastness.

Abstract

The invention provides a disperse scarlet dye composition. The composition contains one or more components A shown in a formula (I) and one or more components B shown in a formula (II), wherein based on the components A and the components B, the mass content of the components A is between 10 and 90 percent; and the mass content of the components B is between 10 and 90 percent. The disperse dye composition can use a liquid state and a cream state obtained after the micronization or a powder state and a particle state obtained after the drying by a spray drying method and the like for dyeing after the commercialized treatment. When the disperse scarlet dye composition dyes hydrophobic fiber such as polyester fiber in an intra-industry conventional mode by adjusting the proportion among different components, a dyed fabric with bright light and beautiful color, good dispersivity, good reproducibility and excellent color fastness can be obtained.

Description

(1) Technical field [0001] The invention relates to a disperse scarlet dye composition, in particular to a disperse scarlet dye composition suitable for hydrophobic fiber dyeing and printing. (2) Background technology [0002] In recent years, through the study of dye compounding synergies, specific components are used to form a new dye composition, which has excellent dyeing performance and fastness performance, making it more and more widely used. There are a lot of patents that are applied to obtain disperse red dyes like this, such as patents CN1927948, US5910624, JP7258571, DE19545873 and the like. However, in actual dyeing applications, the dyeing depth, simultaneous coloring property, and reproducibility of these dyes still cannot fully meet the needs, and facing the increasingly stringent environmental protection and energy saving requirements of the international community, the development of new environmentally friendly dyes has become an industry development tren...
