Problems solved by technology

Therefore, some technicians switched to disperse yellow 54# instead of disperse yellow 23# for blending. The environmental performance of the disperse gray dye thus obtained can meet the requirements of the European Union and other countries, but its sublimation fastness is greatly reduced and cannot meet the requirements of the industry. minimum requirements

Abstract

The invention discloses a grey disperse dye composition. The composition comprises the following components in percentage by weight: 36 to 73 percent of component A, 5 to 25.3 percent of component B and 6.5 to 51.5 percent of component C, wherein the component A is one or more compounds shown as a formula (I); the component B is one or more compounds shown as the formula (II); and the component C is one or more compounds shown as the formula (III). The grey disperse dye composition of the invention has the advantages of environmental friendliness, superior fastness, particularly obvious improvement on sublimation fastness, high strength, low production cost and broad application prospect.

Description

technical field [0001] The invention relates to the field of preparation of disperse dyes, in particular to a gray disperse dye composition. Background technique [0002] With the continuous improvement of living standards, people's requirements for new polyester fibers and textiles have further increased. Correspondingly, higher requirements have been put forward for the dyeing performance and environmental protection performance of dyes. At present, most of the disperse gray dyes on the market are blended with disperse yellow 23#, and disperse yellow 23# is a carcinogenic dye, which has been banned by the European Union and other countries. Therefore, some technicians switched to disperse yellow 54# instead of disperse yellow 23# for blending. The environmental performance of the disperse gray dye thus obtained can meet the requirements of the European Union and other countries, but its sublimation fastness is greatly reduced and cannot meet the requirements of the industr...
