Problems solved by technology

[0005] C.I. Disperse Red 73 has good performance in high-temperature dyeing, but the hot-melt dyeing temperature of this disperse dye is high, which will lead to the destruction of the special-shaped structure of polyester, and the color fixation rate of this disperse dye is hot-melt dyeing at 185-190 ° C Very low, poor reproducibility, it is necessary to find its substitute, which not only has good color fastness performance, but also is suitable for low temperature dyeing

Abstract

The invention discloses a disperse red dye composition. The disperse red dye composition comprises a component A, a component B and a component C, wherein the component A is at least one selected fromthe group consisting of compounds as shown in a formula (I) which is described in the specification; the component B is at least one selected from the group consisting of compounds as shown in a formula (II) which is described in the specification; and the component C is at least one selected from the group consisting of compounds as shown in a formula (III) which is described in the specification. The disperse red dye composition provided by the invention has good color fastness when being applied to low-temperature dyeing of hydrophobic fiber materials like polyester fibers.

Description

[0001] (1) Technical field [0002] The invention relates to a disperse red dye composition and a dye product, in particular to a red disperse dye composition and a dye product with high fastness suitable for printing and dyeing hydrophobic fiber materials. [0003] (2) Background technology [0004] Due to the lack of active groups that can bind to dyes like cellulose or protein fibers in its molecular structure, polyester has high requirements for dyeing conditions, and high temperature and high pressure methods (120 ° C ~ 130 ° C) or hot melt methods are required. (180℃~220℃) dyeing. High-temperature dyeing not only wastes energy, but also increases costs, and brings technical difficulties to the dyeing of polyester blended fibers. Therefore, research on how to reduce the dyeing temperature of polyester fibers has become an urgent problem for printing and dyeing enterprises. [0005] C.I. Disperse Red 73 has good performance in high-temperature dyeing, but the hot-melt dye...
