A kind of blue disperse dye composition for printing

Abstract

The invention relates to a blue disperse dye composition for printing. The dye consists of the following components by weight percent: 3-50 percent of dye A, 0-50 percent of dye B, 0-10 percent of dye C and the balance of aids. The disperse dye composition has extremely high sublimation fastness and washing fastness, the problem that the color of the blue disperse dye composition for printing easily changes is effectively solved, and meanwhile, the dye is high in compatibility and excellent in other color fastnesses and is a high-grade dye suitable for bright-colored printing.

Description

technical field [0001] The invention relates to a blue disperse dye composition, in particular to a blue disperse dye composition for printing. The dye composition is suitable for printing and dyeing of hydrophobic fiber materials. Background technique [0002] In recent years, with the improvement of people's living standards, people have higher and higher requirements for the comfort of clothing fabrics, and at the same time, they have higher and higher requirements for the color fastness of textiles. For example, some printed fabrics not only require bright colors, but also have good washing fastness. Some blue dyes for printing on the market generally have the problem of poor washing fastness; and some disperse dyes with better washing fastness have low self-sublimation fastness and cannot be used for printing. [0003] For example, C.I. Disperse Blue 183 is brighter in color, but its sublimation fastness and washing fastness are poor, so it is not suitable for printing...

AI Technical Summary

Problems solved by technology

At present, some blue dyes for printing on the market generally have the problem of poor washing fastness; and some disperse dyes with good washing fastness have low sublimation fastness and cannot be used for printing.

[0003] For example, C.I. Disperse Blue 183 is brighter in color, but its sublimation fastness and washing fastness are poor, so it is not suitable for printing polyester textiles; C.I. Disperse Blue 284 has better washing fastness, but its color is dark, which cannot satisfy people. The demand for color; therefore, the research and development of bright blue disperse dyes for printing is an urgent problem in the dye industry
