Problems solved by technology

[0002] In the printing and dyeing of hydrophobic synthetic materials, the black and blue series of dyes blended by C.I.DISP.BLUE 291:1, C.I.DISP.VIOLET 93#, and C.I.DISP.ORANGE 76# are the most widely used, but due to their composite dyes in Under certain conditions, it will be cracked to produce aromatic amines that are harmful to the human body and cause allergies to the human body. It has been listed as a banned dye by Germany and other EU countries, so it cannot meet the export needs of printed and dyed textiles

Embodiment 1～15

[0039] According to the data shown in Table 1, dye A, dye B, dye C and dispersant methylnaphthalenesulfonic acid formaldehyde condensate (MF), diffusing agent benzylnaphthalenesulfonic acid formaldehyde condensate (CNF), diffusing agent naphthalenesulfonic acid Formaldehyde condensate (NNO) and sodium lignosulfonate are blended with water, ground and dispersed with a sand mill, and then spray-dried.

[0040] Among them, dye A can be selected from C.I.DISP.BLUE291:1 produced by Zhejiang Runtu Co., Ltd. (mainly composed of dye A and auxiliary agents), and dye B can be selected from C.I.DISP. produced by Zhejiang Runtu Co., Ltd. and Jiangsu Wuxi Dyestuff Factory. VIOLET 93# (mainly composed of dye B and auxiliary agent), dye C can choose DISP.ORANGE 278# (mainly composed of dye C and auxiliary agent) produced by Zhejiang Runtu Co., Ltd.

Abstract

The invention disclosed a blend black and blue series combination dispersion dyes comprising: any one or more dye monomers represented by formula (1), and any one or more dye monomers represented by formula (2), and any one or more dye monomers represented by formula (3). The dyes can be used for printing and dyeing hydrophobic synthetic materials.

Description

technical field [0001] The invention relates to a disperse dye, which is a combined black and blue series disperse dye suitable for printing and dyeing hydrophobic synthetic materials. Background technique [0002] In the printing and dyeing of hydrophobic synthetic materials, the black and blue series of dyes blended by C.I.DISP.BLUE 291:1, C.I.DISP.VIOLET 93#, and C.I.DISP.ORANGE 76# are the most widely used, but due to their composite dyes in Under certain conditions, it will be cracked to produce aromatic amines that are harmful to the human body and cause allergies to the human body. It has been listed as a banned dye by Germany and other EU countries, so it cannot meet the export needs of printed and dyed textiles. Finding alternatives to replace the dye, which must meet environmental protection requirements and have better compatibility with other dyes is a problem that printing and dyeing factories need to solve at present.
