Usage

Uses

Used in Textile Industry:
Disperse Red 72 is used as a dye for various types of fibers, including acetate, polyester, and nylon. It provides a light yellow color when used on acetate fibers, while it gives a blue, lighter color when used on nylon 6 and nylon 66. The dye is also suitable for dyeing polyester/cotton blended fabric in direct printing methods.
Used in Printing Industry:
In the printing industry, Disperse Red 72 is used as a white agent in printing and discharge processes. However, it is not compatible with the ferric sulfate-potassium thiosulfate process.
Standard:
The standard for Disperse Red 72 includes the following ratings for various fastness tests:
Ironing Fastness: ISO 5
Light Fastness: 4-5
Perspiration Fastness: 7
Washing Fastness: 5
Fading: 5
Stain: 5
These ratings indicate the dye's performance in terms of resistance to various conditions, such as heat, light, and moisture.

Disperse dye special for anhydrous dyeing system, preparation and application of disperse dye

The invention relates to a disperse dye special for an anhydrous dyeing system, preparation and application thereof. The preparation process comprises the following steps: firstly, carrying out diazotization reaction on an amino-containing aniline compound to obtain diazonium salt; and carrying out coupling reaction on a coupling component and the diazonium salt to prepare the disperse dye special for the anhydrous dyeing system. According to the invention, the prepared disperse dye special for the anhydrous dyeing system is novel in structure, the molecular structure contains two cyano groups at the same time, the solubility of dye molecules in the anhydrous dyeing system can be obviously reduced, the disperse dye is added into decamethylcyclopentasiloxane while a polyester product is added, a heating dyeing method is adopted for dyeing, a product obtained after dyeing has excellent lifting power performance and deep dyeing performance, when the dye concentration is 0.9% (o.w.f), the Integ value of the product obtained after dyeing reaches 28 or above, the dye uptake is 91% or above, and the color fastness to washing is 4-5 levels; and the disperse dye has excellent deep dyeing performance and color fastness, and the preparation method is simple and easy to popularize.
