Import Direct Yellow R — Buy in Bulk from Supplier in China

Direct Yellow R is a water-soluble azo dye with the C.I. number Direct Yellow 11, supplied as a fine powder with a strength rating of 150% relative to standard reference dyes. It is formulated for direct application on cellulosic fibers such as cotton and rayon, and is also used in paper and plastic coloring where vibrant, stable yellow tones are required. The dye exhibits high solubility in water, enabling uniform dispersion without the need for auxiliary solvents or complex preparation.

The chemical structure of Direct Yellow R is based on a disazo compound, typical of industrial direct dyes used in textile dyeing. It contains no heavy metal components and conforms to standard limits for heavy metals under REACH and Oeko-Tex Standard 100 for textile applications. While the supplier does not specify purity levels, the industry standard for such dyes is typically 95% minimum purity, with moisture content below 5%. The dye is stable under normal storage conditions and does not degrade significantly when kept dry and away from direct sunlight.

This dye is purchased by textile manufacturers in Asia and Eastern Europe for batch dyeing of cotton fabrics, as well as by paper mills producing colored packaging and plastic extruders requiring color consistency. It is packaged in 25kg multi-layer paper bags with inner polyethylene lining to prevent moisture absorption. Trade terms offered include FOB and CIF, with bulk orders typically shipped in 20ft containers. Buyers should confirm the dye's compatibility with their dyeing equipment and fixation methods before placing orders.
