[0002] There are few cationic black dyes for dyeing acrylic and modified polyester, and the black made of cationic blue 41:1 (blue X-GRRL) in the domestic market is the main black variety with a large amount, but it is heat-resistant and temperature-resistant. The performance is extremely poor, and due to environmental protection issues, it is a variety that is not accepted and recognized abroad, so the export of this black dye is restricted

[0028] According to the data shown in Table 1, the yellow dye component, red dye component, blue dye component and additives are pulverized by a mill and mixed in a mixer for 4 to 8 hours to obtain a high-fastness and high-performance cationic black dye.

[0029] For example, the yellow dye component of structural formula (I) can be selected from the cationic golden yellow X-GL produced by Shanghai Jiaye Dyestuff Company, Jiangsu Dongwu Dyestuff Factory, Zhejiang Runtu Co., Ltd., yellow X-5GL, produced by Zhejiang Runtu Co., Ltd. Cationic Yellow X-GRL.

[0030] For example, the red dye component of structural formula (II) can be selected from the cationic red X-GRL produced by Shanghai Jiaye Dyestuff Co., Ltd., Zhejiang Jinjiang Dyestuff Co., Ltd., Zhejiang Runtu Co., Ltd., and the cationic red X-GRL produced by Zhejiang Runtu Co., Ltd. 2BL.

[0031] For example, the blue dye component of structural formula (III) can be selected from the cationic blue X-GRL produced by Shang...

Abstract

A high-fastness high-performance cationic black dye for acrylic fibre fabric is prepared from the yellow dye (15-35 wt.%), the red dye (6-30), the blue dye (8-40) and assistant (rest).

Description

technical field [0001] The invention relates to a cationic black dye with high fastness and high performance, which is especially suitable for printing and dyeing of polyacrylonitrile materials and modified polyester. Background technique [0002] There are few cationic black dyes for dyeing acrylic and modified polyester, and the black made of cationic blue 41:1 (blue X-GRRL) in the domestic market is the main black variety with a large amount, but it is heat-resistant and temperature-resistant. The performance is extremely poor, and due to environmental protection issues, it is a variety that is not accepted and recognized abroad, so the export of this black dye is restricted. Therefore at present each manufacturer is badly in need of looking for the good performance cationic black dye that can effectively replace. Contents of the invention [0003] The invention provides a cationic black dye with high fastness and high performance, which solves the fastness problem of ...
