Import Acid Brown 97 — Buy in wholesale FOB from Supplier in India

ACID BROWN 97 is a synthetic acid dye classified under the Colour Index system, supplied by Viana Chemicals from Ahmedabad, India, for industrial textile and leather coloration. The dye produces brown shades ranging from light tan to deep chocolate depending on concentration and application method, functioning through ionic bonding to wool, silk, and nylon fibers. Viana Chemicals supplies this article in powder or liquid form for textile mills, garment dyeing facilities, and leather finishing operations, with the CI classification indicating standardized coloristic properties for shade matching across suppliers.

The molecular mechanism involves sulfonate groups conferring water solubility and substantivity toward cationic sites on protein and polyamide substrates under acidic conditions. Standard acid brown dyes of this class typically exhibit moderate to good light fastness on wool, with wet fastness improving through after-treatment with syntans or metal salts. The shade depth and hue angle vary with dyebath pH, temperature profile, and electrolyte concentration, requiring controlled application protocols for level results on critical substrates such as woven silk or fine wool worsted.

Beyond textiles, Viana Chemicals notes applications in paper coloration and ink formulations, as well as usage in leather goods including shoes, bags, and belts where a deep brown fashion shade is desired. The listing also references food and cosmetic colorant applications, though buyers in these sectors must verify regulatory compliance independently as food-grade and cosmetic-grade certifications are not stated. Industrial textile and leather processors remain the core buyer segments, with typical trade involving drum or bag packaging for bulk industrial supply.
