For example, C.I. Disperse Orange 29 has excellent light fastness and covering properties and is widely used, but because it is easy to bring in harmful aromatic amines (anthranilic ether) during synthesis, it does not meet the Oeko-Tex Standard 100 ecology promulgated by EU countries. Environmental protection requirements, so it cannot meet the export needs of textiles; another example is C.I. Disperse Orange 30, which has been widely used because of its cheap price, level dyeing property, hiding property, light fastness and other properties, and has become an indispensable polyester fiber. one of the basic colors of
However, the latest Reach regulations and Oeko-Tex Standard 100 require that dyes cannot contain environmentally friendly tetrachloro

Abstract
The invention relates to an environment-friendly orange disperse dye mixture which comprises the following components in percentage by weight: 1%-50% of dye monomers A shown in a formula (I), 1%-70% of dye monomers B shown in a formula (II), 1%-30% of dye monomers C shown in a formula (III) and the balance being additives. According to the environment-friendly orange disperse dye mixture, the defects of C.I. disperse oranges 29 and 30 are effectively overcome, the production cost can be reduced, sewage caused by dyeing is reduced, the dye mixture is ecological and green dye meeting the European Union Reach regulatory requirements and the Oeko-Tex Standard 100 environmental certification, the disperse oranges 29 and 30 can be successfully replaced by the dye mixture, the dye mixture is good in compatibility, wide in pH value range during a dyeing process, high in dye yield, good in leveling property and more outstanding in sublimation fastness and washing fastness especially, and the dye mixture is environment-friendly orange disperse dye superior in various performance.
Description
technical field [0001] The invention relates to an orange disperse dye, in particular to an environment-friendly orange disperse dye mixture, which is suitable for printing and dyeing polyester fibers. Background technique [0002] With the improvement of living standards in recent years, people's awareness of environmental protection has also gradually increased, and higher requirements have been put forward for the dyeing performance and environmental protection performance of dyes. For example, C.I. Disperse Orange 29 has excellent light fastness and covering properties and is widely used, but because it is easy to bring in harmful aromatic amines (anthranilic ether) during synthesis, it does not meet the Oeko-Tex Standard 100 ecology promulgated by EU countries. Environmental protection requirements, so it cannot meet the export needs of textiles; another example is C.I. Disperse Orange 30, which has been widely used because of its cheap price, level dyeing property, hid...
