Processing method of disperse dye for digital printing and application thereof

The invention provides a processing method of dye for digital printing and application thereof, and concretely discloses a purification method of disperse dye raw material 2,6-dichloro-4-nitroanilinefor digital printing and a processing method of the disperse dye for digital printing. The disperse dye for digital printing prepared from the purified 2,6-dichloro-4-nitroaniline has the advantages that the purity is high; the contents of PCB and organochlorine carriers are very low; the content is much lower than the OTEX-100 requirements after the dyeing on the fiber; the crystal form is stable; meanwhile, the heat-resistant sublimation fastness, wear-resistant fastness and the heat-resistant fastness are greatly improved; the colored light is vivid and bright, and the like.

Preparing method of environment-friendly azo dispersing dyestuff

The invention provides a preparing method of environment-friendly azo dispersing dyestuff. The preparing method comprises a diazotization reaction and a coupling reaction, wherein auxiliaries of ferric trichloride, hydrogen peroxide and sodium hypobromite are added in the coupling reaction system. 23 kinds of harmful aromatic amine, benzene containing chlorine, methylbenzene containing chlorine and phenol containing chlorine contained in the dyestuff prepared according to the method are greatly lowered, in this way, the dyestuff conducts dyeing, and 23 kinds of harmful aromatic amine, benzenecontaining chlorine, methylbenzene containing chlorine and phenol containing chlorine on obtained fabric meet limit requirements in an Oeko-Tex Standard100.

Disperse dye composition, and preparation method and application thereof

The invention relates to a disperse dye composition, and a preparation method and application thereof. The disperse dye composition comprises a component A formed by one or more of compounds shown in formula (1), a forbidden aromatic amine compound, chlorinated phenol, chlorobenzene, chlorotoluene, any auxiliary materials and other unavoidable impurities. According to the disperse dye composition, not only are various environment-protective indexes conform to the requirements of Oeko-Tex-Standard 100(2016), but also the total content of the forbidden aromatic amine compound in a dye composition chemical product for dyeing is 10ppm or lower, the total content of each chlorinated phenol is 0.5ppm or lower, and the total content of chlorobenzene and chlorotoluene (COCs) is 1ppm or lower. The sewage after the dyeing also can meet the environmental protection requirement; and meanwhile, the use is more convenient and secure. (Shown in description).
