Disperse blue-to-black dye composition and dye product

Abstract

The invention relates to a disperse blue-to-black dye composition. The disperse blue-to-black dye composition contains the following components in percentage by weight: 35%-95% of a component A and 5%-65% of a component B, wherein the component A is selected from at least one of a formula (I) and/or a formula (II) (shown in the description); and the component B is selected from at least one of a formula (III). The disperse blue-to-black dye composition and a dye product are low in cost, high in strength and good in dye dispersity; and when being applied to the dyeing of hydrophobic fiber materials, the disperse blue-to-black dye composition and the dye product have the characteristics of good improvement force and leveling property, excellent sublimation resistance, wear resistance, washing resistance and perspiration fastness and the like.

Description

(1) Technical field [0001] The invention relates to a disperse blue to black dye composition, in particular to a high fastness disperse blue to black dye composition suitable for printing and dyeing hydrophobic fiber materials. (2) Background technology [0002] In the quality inspection of textile color fastness, color fastness to washing is an important inspection item, and its test results are directly related to the overall color fastness of the fabric. Some dyes with poor color fastness can also cause different degrees of damage to the human body, so different organizations and countries have formulated corresponding standards to strictly limit the color fastness grades of clothing and home textiles. AATCC is the standard of the American Dyestuffers Association, which is quite different from the Chinese national standard (GB / T series) and international standard (ISO series). For example, the color fastness to washing of the same product tested in the series is obviously...

Problems solved by technology

[0003] In order to meet the more stringent textile dyeing requirements, a lot of research and development work has been carried out in the industry. However, due to certain limitations in the dyeing performance of a single dye, those skilled in the art are more likely to increase the multi-component compounding of dyes. Efficacy as a key research and development direction, such as the dyes described in known patents such as ZL201510731091.0, ZL201510731071.3, ZL201510731074.7, compared with single dyes in the dyeing of high-grade polyester fabrics or polyester spandex There are obvious advantages in washing resistance, friction resistance and sublimation resistance. However, the applicant has found through further research that there is still a large room for improvement in terms of cost performance of existing dyes.
