Import Disperse Yellow & Orange — Buy in Bulk from Supplier in China

Disperse Yellow & Orange from Hangzhou Liyi Chemical Co., Ltd are synthetic organic dyes designed for application on hydrophobic fibers such as polyester, nylon, and their blends. The product exhibits a color strength of 100% relative to standard reference batches, with lightfastness rated at 5-6 on the ISO 105-B02 scale, ensuring minimal fading under prolonged UV exposure. Solubility is optimized for high-temperature dye baths between 120°C and 130°C, compatible with conventional exhaust and continuous dyeing methods.

These dyes are formulated without azo groups that release aromatic amines under reductive conditions, aligning with REACH Annex XVII restrictions. The particle size distribution is typically below 2 microns to prevent nozzle clogging in jet dyeing systems. Common variants include Disperse Yellow 23 and Disperse Orange 37, each with distinct absorption maxima at 425 nm and 480 nm respectively. Standard packaging is 25 kg multi-layer kraft paper bags with inner polyethylene lining, sealed for moisture resistance.

Primary buyers include textile mills in Southeast Asia and Eastern Europe that produce synthetic apparel, home textiles, and technical fabrics. The dyes are often blended for custom shades and require precise dosing between 0.1% and 2.5% owf depending on fabric weight and desired depth. Trade terms are typically FOB Shanghai or CIF port of destination, with minimum order quantities starting at 100 kg. Lead time is approximately 15 to 20 days after confirmed order, subject to batch preparation and customs clearance.
