Abstract

The invention relates to a cationic black dye composition and a preparation method and an application thereof. The composition comprises the following components by mass percentage: 2 to 40% of a yellow dye, 2 to 40% of a red dye, and 20 to 90% of a blue dye. The dye composition of the invention is used for dyeing and printing of acrylic fiber, acrylic fiber blended fiber and super cottonlike fiber, has high blackness, and has excellent color fastness.

Description

technical field [0001] The invention belongs to the field of dyes and their preparation and application, in particular to a cationic black dye composition and its preparation and application. Background technique [0002] At present, there are few cationic black dyes for dyeing modified polyester (super-imitation cotton) fibers. Cationic dyeable modified super-imitation cotton is the main variety to replace polyester products in the future, and has broad market prospects. Cationic black dyes generally have disadvantages such as greenish shade, low blackness, poor color fastness, difficult dyeing depth, and unstable shade when dyeing super imitation cotton. Cationic black dye. [0003] The cationic black dyes on the domestic market are mainly black made of blue X-GRRL. However, due to the structure of the blue X-GRRL, its black color is greenish, it is difficult to dye gray when applied, and the dyeing depth is not enough. There are also problems with the color matching of ...
