Problems solved by technology

[0002] In the printing and dyeing of polyester materials, C.I.DISP.YELLOW 23# is the most widely used low-temperature disperse dye, but because its dye will crack under certain conditions, it will produce aromatic amines that are harmful to the human body, causing human body to produce Allergic and carcinogenic effects have been listed as banned dyes by EU countries such as Germany, so they cannot meet the export needs of printed and dyed textiles

Abstract

The invention discloses an environment-friendly combination yellow dispersion dye, which comprises the components (by weight percent) of 15.0-50.5% of compound A represented by formula (1) and 0.2-30.5% of at least one or more compounds B represented by formula (2), and balancing auxiliary agent.

Description

technical field [0001] The invention relates to a disperse dye, which is a yellow combination and environment-friendly disperse dye suitable for printing and dyeing polyester materials. Background technique [0002] In the printing and dyeing of polyester materials, C.I.DISP.YELLOW 23# is the most widely used low-temperature disperse dye, but because its dye will crack under certain conditions, it will produce aromatic amines that are harmful to the human body, causing human body to produce Allergic and carcinogenic effects have been listed as banned dyes by EU countries such as Germany, so they cannot meet the export needs of printed and dyed textiles. Looking for alternatives to replace the dye, which must meet environmental protection requirements and have good compatibility with other dyes (such as C.I.DISPBLUE 56# and C.I.DISP.RED 60#, C.I.DISP.RED50#) is currently required by printing and dyeing factories solved puzzles. Contents of the invention [0003] The inven...
