Problems solved by technology

[0002] In the printing and dyeing of polyester materials, the black and blue series of dyes blended by C.I.DISP.BLUE 291:1, C.I.DISP.VIOLET93#, and C.I.DISP.ORANGE 76# are the most widely used, but because there is one The dye C.I.DISP.ORANGE 76# will be cracked under certain conditions 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 1～12

[0025] According to the data shown in table 1, dye monomer A, dye monomer B, dye monomer C, dye monomer D, dye monomer E, dye monomer F and methylnaphthalenesulfonic acid formaldehyde condensation product (dispersant MF ), naphthalenesulfonic acid formaldehyde condensate (diffusion agent NNO), sodium ligninsulfonate (lignin 85A, 83A) are mixed with water, ground and dispersed with a sand mill, and then spray-dried.

[0026] Among them, dye monomer A and dye monomer B can be selected from C.I.DISP BLUE 291:3# produced by Zhejiang Runtu Co., Ltd., and dye monomer C can be selected from C.I.DISP VIOLET 93# and C.I.DISP produced by Zhejiang Runtu Co., Ltd. VIOLET 93:1#, the dye monomer D can be selected from the disperse orange 30:2# produced by Zhejiang Runtu Co., Ltd., the dye monomer E can be selected from the disperse orange 288# produced by Zhejiang Runtu Co., Ltd., the dye monomer F C.I.DISP BLUE 291# produced by Zhejiang Runtu Co., Ltd. can be selected.

Abstract

The invention discloses a black and blue-series environmental-friendly disperse dye compound, which has the following components based on weight proportion: 5 to 50 portions of mixture of dye monomers A and dye monomers B, 20 to 50 portions of dye monomers C, 1 to12 portions of dye monomers D and 5 to 50 portions of dye monomers E, and also may comprise 1 to 15 portions of dye monomers F. The dye compound has excellent compatibility, wide application range of pH value in dyeing, high color yield, good level dyeing property and good color fastness; particularly in the aspect of washing fastness, the compound has more prominent advantages and is a black and blue-series environmental-friendly disperse dye compound with excellent comprehensive performances.

Description

technical field [0001] The invention relates to an environment-friendly disperse black and blue series dye composition, which is especially suitable for dyeing and printing polyester and blended fabrics. Background technique [0002] In the printing and dyeing of polyester materials, the black and blue series of dyes blended by C.I.DISP.BLUE 291:1, C.I.DISP.VIOLET93#, and C.I.DISP.ORANGE 76# are the most widely used, but because one of the composite dyes The dye C.I.DISP.ORANGE 76# will be cracked under certain conditions 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.
