Disperse dye composition

Abstract

The disperse blue dye composition consists of component A in 1-99 wt% and component B in 1-99 wt% basically, with the structures of component A and component B being shown. The disperse blue dye based on the disperse blue dye composition may be liquid state with particle, emulsion, powder or granule. The disperse blue dye based on the disperse blue dye composition is used in dyeing polyester fiber material, and through regulating the ratio of different components, excellent deep blue dyed fabric with bright color, excellent dispersivity, sunfast property, water resistance, sweat resistance and other advantages may be obtained.

Description

(1) Technical field [0001] The invention relates to a disperse blue dye composition, in particular to a disperse blue dye composition for polyester fiber printing and dyeing. (2) Background technology [0002] Among disperse dyes, disperse blue C.I.56 is recognized as an important blue disperse dye in the world, and the fabric dyed with it can produce particularly bright red light blue with high fastness. But on the other hand, this dye, like all anthraquinone dyes, has the outstanding disadvantage of low dyeing strength, which leads to increased dyeing costs, especially when dyeing dark colors, the cost is high. [0003] In order to overcome the shortcomings of anthraquinone dyes to the greatest extent, and to find dyes that can replace disperse blue C.I.56 and also achieve its excellent dyeing performance, attempts are made such as US Pat. Although the dyeing performance has been improved and the dyeing cost has been reduced, the simultaneous coloring and reproducibility ...

[0003] In order to overcome the shortcomings of anthraquinone dyes to the greatest extent, and to find dyes that can replace disperse blue C.I.56 and also achieve its excellent dyeing performance, attempts are made such as US Pat. Although the dyeing performance has been improved and the dyeing cost has been reduced, the simultaneous coloring and reproducibility of the compound dyes are still unsatisfactory in the actual dyeing process.
