Appearance is yellow powder. It is soluble in water and greenish yellow, slightly soluble in ethanol and acetone, insoluble in other organic solvents. It is greenish yellow in concentrated sulfuric acid, no precipitation after dilution; it is red yellow when concentrated nitric acid. The aqueous solution plus hydrochloric acid does not change color; the sodium hydroxide is hardly discolored. The aqueous solution is decolorized by engraving white blocks, but the oxidizing solution in the air shows reddish purple. When dyeing, copper and iron ions are slightly reddish and dark. Good sex.

Mainly used for wool in strong acid dye in the bath dyeing, silk dyeing in acetic acid bath, polyamide fiber dyeing in formic acid dye bath. This product can be directly on the wool fabric printing, also can dye leather, and can be made into color which. But on paper surface shading, can also be used in paint, medicine and cosmetics of shading.
Acid Yellow 17 is a monoazo acid dye (anionic, water-soluble) commonly referenced as C.I. Acid Yellow 17 (CI 18965) with CAS number 6359-98-4. It is supplied as a yellow powder or liquid dispersion for industrial use.
It is primarily used for protein fibers (wool, silk) and polyamide (nylon) in acidic dye baths; additionally used for leather dyeing, paper coloration, some inks, and as a shading agent in soaps and detergents in industrial contexts.
Acid Yellow 17 is applied in acid dye baths — for wool and silk an acetic/acid bath is common, and for polyamide a formic or mild acid bath is used. pH control in the acidic range improves fiber uptake and leveling; standard dyehouse auxiliaries for acid dyes (salt, acidifying agents, leveling agents) are used to control exhaustion and shade. Always run lab trials to finalize exact pH and temperature profiles for your substrate and equipment.
Yes — it mixes well with compatible acid reds and acid blues to produce oranges, greens and fruit-tones. Shade recipes should be lab-tested because mixing ratios, fiber type and dye exhaustion differ between batches and influence final shade and fastness.
Fastness varies with substrate and fixation method. Acid Yellow 17 typically gives acceptable leveling and bright shade but moderate lightfastness compared with some vat or metal-complex dyes; fastness ratings should be determined from standardized tests for your specific end-use.
As a soluble acid dye, residual dye in effluent is a common concern; removal often requires adsorption, advanced oxidation or coagulation processes. Wastewater treatment protocols and local discharge regulations should be followed — many studies focus on adsorptive removal of Acid Yellow 17 from aqueous streams.
