Embodiment 1

[0063] Disperse 25 g formula (Ⅰ-1), 21 g formula (Ⅱ-1), 12 g formula (Ⅲ-1), 26 g formula (Ⅳ-1), 16 g formula (Ⅴ-1) and 200 g After adding 650 grams of water to mix MF, grind, disperse and dry, the finished product is obtained. This dye can provide the fabric with black with excellent fastness properties.

Abstract

The invention relates to a disperse blue-to-black dye composition and dye product. The composition is mainly composed of a component A, a component B, a component C, a component D and a component E, wherein 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), the component C is selected from one or more of compounds disclosed as Formula (III), the component D is selected from one or more of compounds disclosed as Formula (IV), and the component E is selected from one or more of compounds disclosed as Formula (V). The dye product is mainly composed of the 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

(1) Technical field [0001] The invention relates to a blue to black disperse dye composition and corresponding dye products, in particular to a high fastness blue to black disperse dye composition and dye products suitable for printing and dyeing hydrophobic fiber materials. (2) Background technology [0002] In recent years, in the export orders exported to Europe and the United States, in order to improve the additional performance of textiles, special finishing operations such as heat setting are usually performed on the fabrics. Because the conventional disperse dyes have poor heat transfer resistance, dark polyester fabrics are dyed. In the process of high-temperature tentering and setting after finishing, the dye migrates from the inside of the fiber through the fiber capillary to the surface of the fiber, causing the dye to accumulate on the surface of the fiber, staining other fabrics, and the color fastness to rubbing and washing is significantly reduced, such as during w...
