Acid Violet 17 Appearance is navy blue powder. It is very soluble in water and purple. It is very soluble in ethanol and blue-purple. The dye is red yellow in concentrated sulfuric acid, light green after dilution, and blue-green in concentrated nitric acid. Adding sodium hydroxide is light purple.

Acid Violet 17 is only used for the wool of spell dye, can be used for leather shading.
3. Blending of blended fabrics: When wool is dyed in the same bath as various fibers, the nylon and silk are colored, the acrylic fibers are stained, and the cellulose fibers are slightly stained.
Acid Violet 17 bonds well to protein fibres (wool, silk) and synthetic polyamides (nylon) because its anionic form forms ionic/electrostatic interactions with the positively charged sites on those fibres under acidic conditions. Nylon typically shows very good uptake and brightness; wool and silk will give slightly different warmth and hand — always run a lab swatch to confirm shade and fastness on your exact substrate.
A practical starting recipe: prepare the dye bath at 40–50°C, add dye and soluble salt if needed, then acidify gradually to pH ~4.5 (target range 3.5–5.0) using acetic acid or a commercial acidifier. Raise temperature to the process target (60–95°C depending on fibre) and hold for the recommended time while gentle agitation ensures even leveling. Slow acid addition and controlled temperature ramp improve exhaustion and reduce streaking.
To shift towards bluer/cooler violet, add a small percentage of a blue acid dye with high tinctorial strength (lab trials only). To warm toward red/purple, blend with a small amount of an acid red dye. Use incremental additions (1–5% of the total recipe) and always re-sample — dye interactions and metamerism can appear when lights change.
Mottling commonly results from too rapid temperature or pH changes, insufficient liquor ratio, poor dye dispersion, or inadequate auxiliaries. Remedies: pre-dissolve dye fully, use proper leveling agents or dispersants, control acid addition rate, and use adequate liquor ratio and mechanical circulation. For challenging fibres, a two-bath dyeing or leveled pretreatment can help.
Fastness varies by fibre and post-treatment. On nylon and wool, you can expect good wash retention if the dye bath and fixation are done correctly; lightfastness is often moderate — acceptable for many interior textiles but may not meet highest outdoor standards. For demanding end-uses, evaluate heat/UV ageing and consider after-treatments or protective finishes.
Yes — with formulation changes. For acid printing, it disperses into conventional acid print pastes and gives clean outlines when rheology is correct. For digital textile inks, solvent system, viscosity and pigment vs. dye choice matter; Acid Violet 17 is water-soluble and can be formulated into reactive ink systems for protein/polyamide substrates, but printer compatibility, nozzle stability and pH control require development and testing.
Treat process effluents per local regulations: acid dyes can contribute to colour and COD/BOD in wastewater. Use effective dyehouse effluent treatment (coagulation/flocculation, adsorption, or membrane filtration) and minimize load by optimizing exhaustion and reusing rinse baths where possible. Consult your supplier’s safety data sheet for chemical-specific disposal guidance.
Keep the dye in tightly closed containers, stored cool and dry away from strong oxidizers. Avoid inhalation and prolonged skin contact — use gloves, eye protection and dust control when handling the powder. Have MSDS accessible and follow local PPE and spill procedures.
