Problems solved by technology

However, in the existing disperse dyes, especially dark blue to black dyes, because of the poor thermal migration resistance of the dyes, the dyeing fastness, especially the wet treatment fastness, of the dyed fabrics after heat setting treatment is significantly reduced, which cannot meet the requirements of high-grade polyester. Dyeing requirements of ester fabrics such as sportswear
In addition, with the improvement of the international community's requirements for the ecological and environmental performance of dyes, conventional environmentally friendly dyes (without carcinogenic and allergenic ingredients) tend to exceed the standard in terms of pentachlorophenol, tetrachlorophenol and chlorotoluene, and cannot meet the stricter Oeko- Class II environmental protection requirements of Tex standard 100 have a great impact on the export of dyed fabrics

Embodiment 1

[0051] 30 grams of formula (I-2), 25 grams of formula (II-1), 10 grams of formula (Ⅲ), 5 grams of formula (Ⅳ), 15 grams of formula (Ⅴ-1), 15 grams of (Ⅶ-2) and 250 grams of dispersant MF, after adding 850 grams of water and blending, grinding and dispersing and drying, the finished product is obtained. The dye can provide a blue hue with excellent wet handling properties for fabrics.

Embodiment 2～15

[0055] According to the method described in Example 1, the difference is to adopt the structure and weight of components A to D in Table 1, add 250 grams of auxiliary agents (200 grams of dispersant MF, and 50 grams of sodium lignosulfonate), add water After 850 grams of blending, it is made into a slurry, ground and dispersed, and dried to obtain a finished product. The dye can provide blue to black hues with excellent fastness properties to fabrics.

Embodiment 16

[0064] Select the disperse dyes obtained in the above-mentioned Examples 1 to 15 and Comparative Examples 1 to 4, and use conventional high temperature and high pressure dyeing method and heat setting to process polyester fabrics. During the process, control the dyeing depth (o.w.f) to 3.0%, and the liquor ratio to 1:50 , the pH value of the dyeing bath is 4-5, the dyeing is carried out at room temperature, the temperature is raised to 130°C at 1°C / min, and the temperature is kept for 60 minutes, and the normal method is used to restore and wash, wash with water, dry, and heat-set at 200°C for 1 minute and 30 seconds to obtain the dyed fabric . According to ISO105-X12 and ISO105-C10, respectively test the color fastness to rubbing and soaping, the results are shown in the following table 2:

Abstract

The invention discloses a disperse blue to black dye composition, a dye product, and applications thereof. The disperse blue to black dye composition comprises the following components in percentage by weight: 30 to 80% of blue component A, 5 to 40% of purple component B, 5 to 40% of yellow component C, and 5 to 40% of red component D; wherein the blue component A is a mixture of a compound represented by the formula (I) and a compound represented by the formula (II) according to any ratio, the purple component B is a mixture of a compound represented by the formula (III) and a compound represented by the formula (IV) according to any ratio, the yellow component C is one or more of compounds represented by the formula (V) and / or formula (VI), and the red component D is at least one of the compounds represented by the formula (VII). The disperse blue to black dye product contains the disperse blue to black dye composition and auxiliary agents. The invention also provides the applications of the disperse blue to black dye composition and dye product in printing and dyeing of hydrophobic fiber materials.

Description

(1) Technical field [0001] The invention relates to a disperse blue to black dye composition and its dye product, as well as the application of the dye product on hydrophobic fiber materials. (2) Background technology [0002] In the quality inspection of textile color fastness, wet processing fastness is one of the important inspection items, and its test results are directly related to the overall color fastness of the fabric. However, in the existing disperse dyes, especially dark blue to black dyes, because of the poor thermal migration resistance of the dyes, the dyeing fastness, especially the wet processing fastness, of the dyed fabrics after heat setting treatment is significantly reduced, which cannot meet the requirements of high-grade polyester. Dyeing requirements for ester fabrics such as sportswear. In addition, with the improvement of the international community's requirements for the ecological and environmental performance of dyes, conventional environmenta...
