Usage

Uses

Used in Textile Industry:
Disperse Orange 30 is used as a dye for coloring various types of fibers, including polyester, polyamide, and vinegar fiber. It is particularly effective in dyeing polyester and cotton/polyester blends, and can also be used for direct printing and preventing discharge printing to color.
Used in Dyeing Methods:
Disperse Orange 30 is used in high-temperature and high-pressure dyeing methods, where it can be applied in the dark and has a low dyeing rate. The size of the bath ratio of coloring rate is influential in the dyeing process.
Standard:
Disperse Orange 30 has been tested for various standards, including ironing fastness, light fastness, perspiration fastness, and washing fastness. The results for these tests are as follows:
Ironing Fastness: AATCC 4-5, ISO 5
Light Fastness: AATCC 4-5, ISO 7

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.

Diazotization method of wet nitroaniline

The invention provides a diazotization method of wet nitroaniline, and relates to the field of dye synthesis. The diazotization method comprises following steps: step one, evenly stirring sulfuric acid (98%) and nitrosyl sulfuric acid (40%) in a diazotization reactor; and step two, adding wet nitroaniline into the diazotization reactor at a controlled temperature of -10 to 40 DEG C to obtain diazotization salts, wherein the mole ratio of sulfuric acid to nitrosyl sulfuric acid to diazotization component is 1.0-6: 1.02-1.1: 1. The quality of the provided wet dye is the same as that of a dry product, the diazotization component does not need to be dried, and the provided dye is energy saving and environmentally friendly.

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.

Production technology of disperse orange

The invention discloses a preparation method of disperse orange. The method comprises the following step of coupling diazonium salt and N-acetylyloxyethyl-N-cyanoethylaniline for 2h under the temperature of 25-35 DEG C to obtain the disperse orange, wherein the material adding sequence in the coupling reaction is that diazonium salt is added to N-acetylyloxyethyl-N-cyanoethylaniline. According tothe production technology, the requirements of people on environmental protection indexes can be met; the cost is decreased; the output is increased; the color of the product is consistatn with that produced by other technologies in the prior art.

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).

Preparation method of ester group-containing azo disperse dye

The invention discloses a preparation method of an ester group-containing azo disperse dye. The method comprises the following steps: carrying out a coupling reaction on a diazo salt and a coupling component, adding an alkali to the above obtained azo compound material system after the coupling reaction is completed in order to adjust the pH value of the system to 5-7, carrying out heating crystal transformation, and post-processing to obtain a dye filter cake. The pH value of the system is adjusted to 5-7 after the coupling reaction and before the crystal transformation, so hydrolysis of ester groups in the dye product is avoided, the yield of the dye product is improved, and the content of organic matters in wastewater is reduced, thereby the wastewater post-treatment difficulty is reduced.
