Import Direct Yellow 86 — Buy in Bulk from Supplier in China

Direct Yellow 86 is a diazo direct dye with CAS No. 50925-42-3, designed for dyeing cotton, wool, and synthetic blends. It is supplied as a fine yellow powder with high water solubility and stable color performance under standard dyeing conditions. The product is used in textile printing and bulk dyeing applications where consistent shade and ease of application are priorities.

This dye belongs to the class of water-soluble direct dyes with moderate to good wash fastness on cellulosic fibers. Its molecular structure includes sulfonic acid groups that enhance solubility and fiber affinity. Typical industry specifications allow for a purity of 90% to 95%, moisture content under 3%, and insoluble matter below 0.5%. The dye is not classified as a restricted substance under EU REACH Annex XVII, though compliance must be verified per batch.

Buyers in the textile, paper, and leather sectors use Direct Yellow 86 for medium-fastness applications such as interior textiles, disposable garments, and packaging materials. It is often selected where cost efficiency and ease of processing outweigh the need for high lightfastness. Trade terms are typically FOB Tianjin, with lead times of 15 to 20 days. Packaging is in 20kg or 25kg polypropylene bags with inner polyethylene lining.
