[0034] According to the data shown in Table 1, add yellow dye, red dye, blue dye, and diffusing agent NNO into the mixer, and mix for 4 to 8 hours to obtain cationic black dye for modified polyester dyeing.

[0035] The yellow dye can be selected from the golden SD-GL and yellow SD-5GL produced by Zhejiang Runtu Co., Ltd., Shanghai Qingcheng Dyestuff Chemical Co., Ltd., Shanghai Jiaye Dyestuff Chemical Co., Ltd., and the yellow SD-GRL produced by Zhejiang Runtu Co., Ltd. . The red dye can be selected from the red SD-GRL and bright red SD-5GN produced by Zhejiang Runtu Co., Ltd., Shanghai Qingcheng Dyestuff Chemical Co., Ltd., Shanghai Jiaye Dyestuff Chemical Co., Ltd., and the red SD-5GN produced by Zhejiang Runtu Co., Ltd. 2BL. The blue dyes can be blue SD-GSL and blue SD-BL produced by Zhejiang Runtu Co., Ltd., Shanghai Qingcheng Dyestuff Chemical Co., Ltd., Shanghai Jiaye Dyestuff Chemical Co., Ltd., and blue SD-BL produced by Zhejiang Runtu Co., Ltd. 4GSL, Lan SD-F2RL. ...

Abstract

The present invention discloses a kind of cationic black dyes used in modified Dacron and blend dye for Dacron and acrylic textiles, which comprise the following components by weight: 10-40 percent of yellow dyes by chemical formula weight (I), 10-40 percent of hyperon by chemical formula weight (II), 5.8 percent of the blue dyes by chemical formula weight (III) and the rest accessory ingredients. The inventive dyes solve the problem that fails to heat resistance in the two process and cationic dyes, and bright-color remains unchanged and the fastness heightened.

Description

technical field [0001] The invention relates to a cationic black dye used for dyeing modified polyester, especially suitable for dyeing modified polyester, one-bath dyeing of modified polyester and acrylic fiber, and one-bath dyeing of modified polyester and polyester. Background technique [0002] The output of modified polyester is increasing rapidly, and the amount of blended fabrics of polyester and modified polyester, and polyester and acrylic is also increasing. According to the traditional dyeing process, disperse dyes and cationic dyes are used for two-bath dyeing, but disperse dyes are high temperature and high pressure. Dyeing, and cationic dyes are not resistant to high temperature and pressure, so the choice of conventional dyes will lead to a decrease in the dyeing effect, especially the decrease in the brightness of cationic dyes, damage to the fastness, the dyeing of modified polyester and the blended fabric of modified polyester and acrylic Dyeing, choosing t...
