Usage

Preparation

2-Cyano-4-nitroaniline diazo, and N-hydroxyethyl-N-methoxycarbonylethylaniline? coupling.

Properties and Applications

Red. The dark red powder appearance. Dye bath of iron ion in light of the impact is not big, encounter copper ions that change color. Dyeing appropriate pH value for 4 ~ 5. When in dyeing and printing alkaline resistance is poor. The dyes light yellow color, and the fastness is better. Suitable for all the dyeing method, dye vinegar fiber, colored light and polyester similar, the sun is good fastness, in dye three vinegar when fiber color light yellow, in dye nylon 6 and nylon 66, color is blue, shallow color to dye. But in the polyester/cotton blended fabric printing directly. In printing and discharge the impression that can be used while he’s as white agent, can not adapt to the ferrie sulfate-potassium thiosulfate Standard Ironing Fastness Light Fastness Persperation Fastness Washing Fastness Fading Stain Fading Stain Fading Stain ISO 5 4-5 7 5 5 5 5

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.
