Import Direct Yellow 6 — Buy in Bulk from Supplier in India

Direct Yellow 6 is a water-soluble azo dye with the C.I. number 40001 and CAS number 1325-38-8, appearing as a brilliant yellow powder. It dissolves readily in water to produce a golden brown hue and shows moderate solubility in ethanol, slight solubility in acetone, and good affinity for cellulose and polyamide fibers. The dye exhibits a distinct color shift under strong sulfuric acid, turning red-purple, and fluoresces purple under blacklight.

This dye is formulated for direct application on cellulosic fibers including cotton, flax, viscose rayon, acetate, and jute, and is also used in paper and leather coloring. Its discharge characteristics are favorable for printing applications where color removal is required. The chemical structure supports strong substantivity without requiring mordants, making it suitable for batch dyeing processes where simplicity and cost-efficiency are priorities.

Buyers typically source Direct Yellow 6 for textile mills producing low-cost printed fabrics, paper manufacturers requiring vibrant yellow tones, and leather finishers seeking consistent coloration. The dye is supplied in 25kg polypropylene bags with inner moisture barrier lining. Standard packaging ensures stability during ocean freight. Buyers should confirm batch-to-batch consistency through spectrophotometric analysis and request a certificate of analysis for purity and insoluble content.
