Problems solved by technology

However, disperse blue 56 also has certain limitations. When it is applied to fabric dyeing, the coloring rate is not high, which increases the cost of use, and the discharged dyestuffs are discharged into wastewater, causing environmental pollution. In addition, metal ions, especially copper, are Ions are relatively sensitive, and the production process of this dye has a greater impact on the environment

Embodiment 3～15

[0054] According to the method described in Example 1 or 2, the difference is that the structure and weight of components A to D in Table 1 are adopted, 200 grams of auxiliary agents are added (150 grams of dispersant MF, and 50 grams of lignin 85A), and water is added. 650 grams of blending are made into a slurry, ground and dispersed, and dried to obtain a finished product. The dye can provide a blue hue with excellent fastness properties to the fabric.

Abstract

The invention provides a disperse blue dye composition. The disperse blue dye composition comprises, by mass, 30-85% of a component A, 1-30% of a component B, 1-30% of a component C and 1-30% of a component D. The component A is a compound shown in the formula (I). The component B is one or more of compounds shown in the formula (II). The component C is one or more of compounds shown in the formula (III). The component D is one or more of compounds shown in the formula (IV). The disperse blue dye composition has the characteristics of excellent sublimation resistance, friction resistance and water washing resistance in the dyeing of hydrophobic fiber materials.

Description

[0001] (1) Technical field [0002] The invention relates to a disperse blue dye composition, in particular to a disperse blue dye composition and a dye product suitable for printing and dyeing hydrophobic fiber materials. [0003] (2) Background technology [0004] C.I. Disperse Blue 56 is recognized as an important blue disperse dye in the world, because it can not only obtain bright color but also has good light fastness in the dyeing of hydrophobic fibers (especially polyester fibers). The anthraquinone-type C.I. disperse blue 56 disclosed on page 582 of the first volume of "World Dyestuff Varieties - 2005" has a bright color when dyeing, is resistant to weak alkalis, and has good light fastness, so it has become a widely used main color dye. However, disperse blue 56 also has certain limitations. When it is applied to fabric dyeing, the coloring rate is not high, which increases the cost of use, and the discharged dyestuffs are discharged into wastewater, causing environme...
