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

Embodiment 1-10
[0026] According to the data shown in Table 1, the original dye A, dye B, and dye C of the metering ratio are pre-dispersed and crushed, then add additives and warm water to stir, disperse and dissolve, and repeat continuous grinding and filtration. After sanding to the end point, pass The pipeline is sent to a spray drying tower for drying, and at the same time, dust-proof oil and dispersant are sprayed evenly, and finally the finished product is packaged.

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...
