从India供应商批发进口Acid Yellow 3 — FOB条款

Acid Yellow 3, also known as Quinoline Yellow or Acid Yellow Quinoline FF, is an synthetic acid dye with the chemical formula C18H9NNa2O8S2 and CAS number 8004-92-0. Sparrowings International supplies this dye from their base in Ahmedabad, Gujarat, in powder form for leather and textile dyeing applications. The product carries EINECS registration 616-849-0, confirming its regulatory status within the European chemical inventory.

As an acid dye, this molecule contains sulfonic acid groups that enable bonding to protein fibres such as wool, silk, and nylon, as well as to leather substrates through electrostatic attraction. The quinoline-based chromophore delivers a bright yellow hue with good tinctorial strength. Standard commercial grades typically exhibit dye content of 80 to 85 percent minimum, with the remainder comprising diluents and moisture to ensure stable powder flow and reproducible shade development.

Textile mills and tanneries represent the primary buyers, using Acid Yellow 3 for piece dyeing, yarn dyeing, and leather finishing where lightfastness requirements are moderate to good. Sparrowings International lists this product for both leather and textile dyestuff markets. Buyers should confirm the exact dye content, application method (exhaust or padding), and compatibility with their specific substrate and subsequent finishing treatments before committing to volume orders.
