Problems solved by technology

[0002] Conventional disperse gray dyes are generally composed of C.I.Disperse Blue 56, C.I.Disperse Red 60, and C.I.Disperse Yellow 54. The pH range of this composition can only be between 3-8, and the cost is high, and the compatibility between dyes is general , the head-to-tail color difference is large, the lifting rate is low, the dye utilization rate is not high, and the sublimation fastness is poor

Abstract

The present invention discloses a disperse grey dye composition, which consists of the components in percentage by weight: 15-25% of component A, 25-50% of component B and 30-50% of component C, wherein the component A is one or more compounds shown in formula (I) and the component C is one or more compounds shown in formula (III). The disperse grey dye composition provided by the invention has extremely excellent compatibility and high dyeing rate, is mainly used for the dyeing of polyester fibers, has excellent fastness to light, fastness to rubbing, fastness to sublimation and the like when being used for dyeing polyester fiber fabrics, especially has very good sublimation fastness, can dye in a wide pH range and has little pollution.

Description

technical field [0001] The invention relates to a disperse dye composition, in particular to an environment-friendly disperse gray dye composition which is suitable for dyeing in a wide pH range, has good compatibility and good sublimation fastness. Background technique [0002] Conventional disperse gray dyes are generally composed of C.I.Disperse Blue 56, C.I.Disperse Red 60, and C.I.Disperse Yellow 54. The pH range of this composition can only be between 3-8, and the cost is high, and the compatibility between dyes is general , the color difference between head and tail is large, the lifting rate is low, the dye utilization rate is not high, and the sublimation fastness is poor. [0003] In order to solve these problems, it is an important subject of current research to propose environmentally friendly dyes that can be dyed within the range of PH value 2-11, have good compatibility, good sublimation fastness, and are relatively economical.
