Abstract

The invention discloses a compounding dispersing dye that is suitable for dye printing polyester material. The invention could make the bright yellow product that has high concentration, and reduce polluted water. It has good dyeing repeatability and good color fastness.

Description

technical field [0001] The invention relates to a disperse dye, which is a bright yellow combined disperse dye suitable for printing and dyeing polyester materials. Background technique [0002] In the printing and dyeing of polyester materials, C.I.DISP.YELLOW 134# is a widely used high-temperature bright yellow disperse dye, but because of its poor lifting power, it cannot meet the needs of printing and dyeing. Looking for alternatives to replace the dye must meet environmental protection requirements and be compatible with other dyes (such as C.I.DISP BLUE 56# and C.I.DISP.RED 60#, C.I.DISP.RED50#, C.I.DISP.BLUE 183#, C.I.DISP.BLUE 60#) have good compatibility. Contents of the invention [0003] The invention provides a bright yellow combined disperse dye, which solves the lifting force problem of C.I.DISP.YELLOW134# and can meet environmental protection requirements. [0004] A bright yellow combined disperse dye, containing the following components by weight percent...
