Import Direct Dyes — Buy in Bulk from Supplier in India

Direct dyes from Tanya Exports are water-soluble anionic dyes used primarily for dyeing cellulosic fibers such as cotton, rayon, and paper. The listing confirms these dyes are formulated for good solubility in alkaline conditions and exhibit moderate to good wet fastness on cotton. They are applied under neutral to slightly alkaline pH, typically at temperatures between 80°C and 95°C, with salt as a leveling agent to promote even absorption.

These dyes are typically composed of azo or anthraquinone structures, with molecular weights ranging from 300 to 1000 g/mol, which affects their penetration and affinity for cellulose. While the listing does not specify exact chemical grades, industry-standard direct dyes are classified by shade range and fastness properties, with common types including Direct Black, Direct Blue, and Direct Red. They are not suitable for synthetic fibers like polyester without mordants or after-treatments.

Buyers in the textile printing and small-batch dyeing sectors use these dyes for cotton fabrics, home textiles, and industrial paper coloring. The supplier does not state MOQ, lead time, or packaging details, but standard bulk packaging is 25 kg polypropylene bags with inner moisture barrier. Trade terms are not specified; buyers should confirm Incoterms and payment conditions directly with the supplier before shipment.
