Problems solved by technology

However, disperse blue 56 also has its own insurmountable shortcomings: the coloring rate is very low during fabric dyeing, which greatly increases the cost and causes serious environmental pollution.
There is a phenomenon of uneven dyeing when the modern fast printing and dyeing method is used to dye the fabric. This problem can only be solved by increasing the dyeing time.

Embodiment 1

[0048] Mix 65 grams of compound of formula (I), 25 grams of compound of formula (II-1), 10 grams of compound of formula (III-1) and 300 grams of dispersant MF, add 1000 grams of water, grind, disperse and dry to obtain Finished product, the dye can provide blue color with excellent fastness properties to the fabric.

[0049]

Embodiment 2

[0051] Mix 40 grams of compound of formula (I), 20 grams of compound of formula (II-2), 20 grams of compound of formula (III-2) and 280 grams of dispersant MF, add 850 grams of water, grind, disperse and dry to obtain Finished product, the dye can provide blue color with excellent fastness properties to the fabric.

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 C in Table 1 are adopted, 280 grams of auxiliary agents are added (250 grams of dispersant MF, 30 grams of lignin 85A), and water is added. 850 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

Disperse blue dye composition is prepared from, in percentage by mass, 30%-85% of a component A, 5%-40% of a component B and 5%-30% of a component C on the basis of the component A, the component B and the component C. The component A is a compound shown in formula (I), the component B is selected from at least one of compounds shown in formula (II), and the component C is selected from at least one of compounds shown in formula (III). The disperse blue dye composition and a dye product have the characteristics of excellent sublimation resistance, friction resistance, washing resistance and the like when applied to 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 disperse blue 56# disclosed on page 582 of the first volume of "World Dyestuff Varieties-2005" has bright shade, weak alkali resistance and good light fastness during dyeing, so it has become a widely used main color dye. But disperse blue 56 also has its own insurmountable shortcomings: the coloring rate is very low when the fabric is dyed, which greatly increases the cost and causes serious environmental pollution. There is a phenomenon of uneven dyeing when modern f...
