Usage

Uses

Used in Textile Industry:
Disperse Violet 93 is used as a dye for coloring polyester/cotton blended fabrics and pure polyester fabrics in dyeing and printing processes. Its application is favored due to its excellent fastness properties, which include:
1. Ironing Fastness: Rated at ISO 4-5, the dye maintains its color and does not fade or stain when exposed to high temperatures during ironing.
2. Light Fastness: Also rated at ISO 4-5, Disperse Violet 93 demonstrates resistance to fading when exposed to sunlight or artificial light sources.
3. Perspiration Fastness: Rated at ISO 5, the dye remains colorfast and does not transfer onto skin or other fabrics when in contact with sweat.
4. Washing Fastness: Rated at ISO 5, Disperse Violet 93 shows high resistance to fading or staining when subjected to washing processes.
In addition to its use in the textile industry, Disperse Violet 93 is also utilized in environmental testing, where it may be employed to assess the impact of dyes and their metabolites on the environment.

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.
