Abstract

The invention relates to a high-fastness disperse dark blue dye composition and dye product. The disperse dark blue composition is mainly composed of the following components in percentage by mass: 50-98% of component A, 1-25% of component B and 1-25% of component C. The component A is selected from one or more of compounds disclosed as Formula (I); the component B is selected from one or more of compounds disclosed as Formula (II); and the component C is selected from one or more of compounds disclosed as Formula (III). The disperse dark blue dye product is mainly composed of the disperse dark blue composition and assistants. When being used for hydrophobic fiber material dyeing and after-finishing, the dye product has excellent fastness to washing and fastness to rubbing, and is very suitable for printing and dyeing of high-grade textiles.

Description

[0001] (1) Technical field [0002] The invention relates to a deep blue disperse dye composition and a dye product, in particular to a high fastness dark blue disperse dye composition and a dye product suitable for printing and dyeing hydrophobic fiber materials. [0003] (2) Background technology [0004] In recent years, in order to improve the additional performance of textiles in the export bills exported to Europe and the United States, special finishing operations such as heat setting are usually carried out on the fabrics. Due to the poor heat migration resistance of conventional disperse dyes, dyeing dark polyester fabrics During the post-finishing high-temperature stenter setting process, the dye migrates from the inside of the fiber to the surface of the fiber through the fiber capillary, causing the dye to accumulate on the surface of the fiber, contaminating other fabrics, and the color fastness to friction and washing is significantly reduced. The staining fastnes...
