Abstract

A medium-temp composite disperse red dye with high dye uptake, compatibility, dyeing uniformity and fastness contains proportionally dye monomer A, B and C and assistant.

Description

technical field [0001] The invention relates to a dye composition, in particular to a composite medium-temperature dye suitable for printing and dyeing polyester materials. Background technique [0002] In the printing and dyeing of polyester materials, Disperse Red S-5BL (Disperse Red S-2GFL, namely C.I.DISP.RED 167#) is a widely used dye, and it is compatible with C.I.DISP.BLUE 79# and C.I.DISP .ORANGE 30# has become one of the more typical high temperature three primary color combinations. However, when the dye is used alone, the reproducibility and coloring rate are not good, the sublimation fastness is poor, and the pollution of three wastes is relatively large. [0003] Publication No. is CN1597790A invention patent application open specification discloses a kind of composite disperse red dye, contains following components by weight percentage: 20%-45% monomer A (main component of commercially available C.I.DISP.RED 145#) and 5%-15% of monomer B (main component of co...
