Acid Yellow 73, also known as Urainine, is a synthetic organic dye from the acid dye class, primarily used for its bright yellow colouration in textile and industrial applications. This product is formulated for high solubility in water, enabling even penetration into fibres such as wool, nylon, and silk. The dye’s molecular structure ensures strong affinity for protein and polyamide substrates, delivering consistent colour yield under typical dyeing conditions.
The dye is produced using premium acids and compounds, as stated by the supplier, and is available in powder form. Acid dyes like this are standard in the industry for their ability to produce vibrant, fast colours on natural and synthetic fibres. Typical industry specifications for Acid Yellow 73 include a pH range of 2 to 4 for optimal dye uptake, with standard light fastness rated at 4 to 5 on the ISO 105-B02 scale, though exact values should be confirmed with the supplier.
Common applications include dyeing wool for apparel, nylon for carpets and upholstery, silk for luxury textiles, as well as leather, paper, and ink. Buyers in the textile and manufacturing sectors source this dye for its reliability in bulk production. Trade terms such as packaging options, MOQ, and lead times are available upon direct inquiry, as these are not specified in the listing.
