Problems solved by technology

However, disperse blue 56 also has its own insurmountable shortcomings: the low dyeing rate in fabric dyeing greatly increases the cost and causes serious environmental pollution; there is uneven dyeing when modern fast printing and dyeing methods are used to dye fabrics , this problem can only be solved by increasing the dyeing time
In addition, it is sensitive to metal ions, especially copper ions in the dye bath, and the pollution in the production process of this dye is extremely high

Abstract

The invention provides a disperse blue dye composition. The disperse blue dye composition comprises, by mass, 5-95% of a component A, 1-60% of a component B and 1-60% of a component C. The component Ais a dye compound shown in the formula (I). The component B is one or more of compounds shown in the formula (II). The component C is a dye compound shown in the formula (III). The invention also provides a disperse blue dye product. The disperse blue dye product comprises the disperse blue dye composition and an aid. The weight ratio of the aid to the disperse blue dye composition is 0.2 to 5: 1. The disperse blue dye composition and its product are used in dyeing of a hydrophobic fibrous material and have the characteristics of excellent sublimation resistance, friction resistance, water washing resistance and light fastness.

Description

(1) Technical field [0001] 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. (2) Background technology [0002] 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. However, disperse blue 56 also has its own insurmountable shortcomings: the low dyeing rate in fabric dyeing greatly increases the cost and causes serious environmental pollution; there is uneven dyeing when modern fast printing and dyeing methods are used to dye fab...
