Problems solved by technology

[0002] In the printing and dyeing of polyester materials, the black and blue series 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 compounded 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

Abstract

An environmental protection type composite disperse green dye with high dyeing uniformity, producibility and dye uptake contains proportionally dye monomers A, B, C and D and assistant.

Description

technical field [0001] The invention relates to a disperse dye, which is a compound environment-friendly disperse dye suitable for printing and dyeing polyester materials. Background technique [0002] In the printing and dyeing of polyester materials, the black and blue series 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 compounded 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. Contents of the invention [0003] The in...
