Acid Yellow 14 is a water-soluble anionic acid dye that produces bright, clear yellow shades. It is formulated for acid-dyeing processes and shows good affinity for protein and polyamide fibers, making it suitable for applications in textiles, leather, paper, and aqueous inks. Acid Yellow 14 is valued for its vivid chroma and ease of application in standard acid dye systems.

Used for dyeing wool and silk, good leveling.
Acid Yellow 14 shows strongest affinity for protein fibers (wool, silk) and synthetic polyamides (nylon). It is primarily used in acid dyeing processes; compatibility with other fiber types depends on process chemistry and may require pre- or post-treatment.
Standardize a small lab shade recipe and keep a master stock solution. Control liquor ratio, dosing sequence, and agitation, and use the same auxiliary packages. Run a lab-scale trial and record exhaustion values and bath pH so you can reproduce the same dye uptake at scale.
Yes for some aqueous ink systems — especially where a water-soluble acid dye is required for substrate affinity. Compatibility depends on the ink vehicle, binder, and print process; test for bleed, crocking and lightfastness before production use.
Acid Yellow 14 typically gives bright color with moderate wash and lightfastness. Fastness can be improved by after-treatments (e.g., appropriate fixatives or finishing resins), optimizing exhaustion, and choosing complementary auxiliary chemistries for the fiber type.
Yes — it blends well with other acid dyes to produce a wide range of yellow-green to orange-yellow tones. For predictable results, prepare small-scale mix trials and record the blend ratios and process parameters.
Because it is water-soluble, residual dye may remain in effluent. Implement good bath control, recovery, and wastewater treatment (filtration, adsorption or biological treatment) to reduce color load and chemical oxygen demand (COD).
Store in a cool, dry place in tightly sealed containers. Avoid contamination with moisture or other chemicals. Consult the product SDS for PPE, spill response and disposal guidance.
Perform basic QC: visual color check, dye strength assay (spectrophotometric test against a reference), moisture content, and pH of a standard solution. Keep certificate of analysis (CoA) documentation and test a small production run before full-scale use.
