Abstract

The invention discloses an environment-friendly disperse dye composition, which comprises the following components by weight percent: 10-75% of dye monomer A as shown in formula (1), 2-35% of dye monomer B as shown in formula (2), 8-50% of dye monomer C as shown in formula (3), and 1-10% of dye monomer D as shown in formula (4). The disperse dye composition can be regulated to obtain colored lights such as black, blue, grey, brown and the like; the obtained dye composition is an environment-friendly dye, and has wide suitable range of the pH value, good pile-on property, strong covering performance, good lifting power, colour yield, levelling property and various fastness, and can greatly improve the utilization rate of the dye and reduce the dye sewage.

Description

technical field [0001] The invention relates to an environment-friendly disperse dye composition, which is especially suitable for dyeing and printing polyester and its blended fabrics. Background technique [0002] Among disperse dyes, C.I.Disperse Orange 76# (76# Orange) is usually compounded with C.I.Disperse Blue 291:1# and C.I.Disperse Violet93# because of its good level dyeing property, excellent fastness and color matching, and has a high blending effect. High-strength black and blue series of disperse dyes. The black and blue series of disperse dyes not only have high strength but also excellent dyeing depth, and are widely used in printing and dyeing of polyester materials. However, because 76# orange will be cracked under certain conditions to produce aromatic amines that are harmful to the human body and cause allergies to the human body, the high-strength black and blue series of disperse dyes with 76# orange have been listed by Germany and other European Union ...
