Problems solved by technology
[0002] In the printing and dyeing of polyester materials, most of the blue disperse dyes used have defects such as color brilliance, pH sensitivity, sublimation fastness, washing fastness, rubbing fastness, and the promotion rate of hot-melt dyeing. For example, the commonly used C.I. Disperse Blue 60 can obtain bright color and good color fastness when dyed on polyester fiber, resulting in a large amount of use in the market, but because of its low coloring rate, sensitivity to metal ions, Poor level dyeing, high dyeing cost, and large amount of pollution in the production process have led to great restrictions on the application of C.I. Disperse Blue 60
[0003] Therefore, there are some alternatives to C.I. Disperse Blue 60 on the market, but these alternatives have gradually been found by manufacturers: the shade of the substitutes is not as bright as C.I. Disperse Blue 60, and many prescriptions cannot be directly replaced; and the color fastness of the substitutes The intensity is also worse than C.I. Disperse Blue 60; the levelness is not much improved

Abstract
The invention discloses a blue disperse dye mixture. The dye mixture is prepared from the following ingredients of a dye monomer A, represented by a chemical formula (1) shown in a drawing, with the weight percent of 10-80%, a dye monomer B, represented by a chemical formula (2) shown in a drawing, with the weight percent of 0-20%, a dye monomer C, represented by a chemical formula (3) shown in a drawing, with the weight percent of 0-20%, a dye monomer D, represented by a chemical formula (4) shown in a drawing, with the weight percent of 0-10% and the balance of adjuvants. The dye mixture disclosed by the invention meets the environmental-friendly and ecological requirements of European Community Oeko-Tex Standard 100; on the premise that the condition that color light of the dye mixture is consistent with that of C.I. disperse blue 60 is guaranteed, the dye mixture is plump in color and luster, high in coloring rate, insensitive to metal ions, good in upgrading power and good in even dyeing performance, and the washing fastness, sublimation fastness and rubbing fastness are improved greatly; and the dye mixture has the advantages of good compatibility, low dyeing cost, and the like.
Description
technical field [0001] The invention relates to a disperse dye, in particular to a blue disperse dye mixture. Background technique [0002] In the printing and dyeing of polyester materials, most of the blue disperse dyes used have defects such as color brilliance, pH sensitivity, sublimation fastness, washing fastness, rubbing fastness, and the promotion rate of hot-melt dyeing. For example, the commonly used C.I. Disperse Blue 60 can obtain bright color and good color fastness when dyed on polyester fiber, resulting in a large amount of use in the market, but because of its low coloring rate, sensitivity to metal ions, Poor level dyeing property, high dyeing cost, and large amount of pollution in the production process lead to great restrictions on the application of C.I. Disperse Blue 60. [0003] Therefore, there are some alternatives to C.I. Disperse Blue 60 on the market, but these alternatives have gradually been found by manufacturers: the shade of the substitutes i...
