Embodiment 1

[0030] Raw materials were prepared according to the following components and weight: Dye monomer K 4.2g, Dye monomer L 7.75g, Dye monomer M-10.03g, Dye monomer N 0.99g, Dispersant MF 50g, Sodium lignosulfonate 5g.

[0031] Mix dye monomer K, dye monomer L, dye monomer M-1 and dye monomer N, add dispersant MF and sodium lignosulfonate, stir evenly, add water to moisten, grind, and then spray dry to prepare A blue disperse dye composition is obtained.

Embodiment 2-10

[0033] Except that the blue disperse dye composition was prepared according to the components and contents in Table 1, Examples 2-10 were carried out in the same manner as Example 1.

Abstract

The invention discloses a blue dispersed dye composition which comprises the following components based on the total weight of the composition: 2-60wt% of a dye monomer K of a chemical formula (i), 0.1-15wt% of a dye monomer L of a chemical formula (ii), 0-10wt% of a dye monomer M of a chemical formula (iii), 0.1-5wt% of a dye monomer N of a chemical formula (iv), and the remnants are additives. By adopting the blue dispersed dye composition disclosed by the invention, the dyeing degree can be greatly increased, and the color fastness and the washing fastness can be greatly improved.

Description

technical field [0001] The invention relates to a disperse dye, in particular to a blue disperse dye composition. Background technique [0002] As we all know, C.I. Disperse Blue 60 has been recognized by printing and dyeing enterprises for its bright color and good color fastness when dyeing polyester fibers, resulting in a large amount of use in the market, but still has low coloring rate and sensitivity to metal ions , poor level dyeing property, etc., and the dyeing cost is high, and the amount of pollution in the production process is large, causing the application of C.I. Disperse Blue 60 to be greatly restricted. Therefore, finding a product that can effectively replace C.I. Disperse Blue 60 is still a difficult problem for printing and dyeing manufacturers. [0003] For overcoming these shortcomings, Chinese patent application CN201310408935.9 discloses a kind of blue disperse dye mixture, and this dyestuff is made up of following components: the dye monomer A such ...
