Description

Reactive Orange 15 is a high-purity, reactive dye belonging to the azo dye class, specifically designed for covalent bonding with cellulosic and protein-based fibers. Its primary value lies in providing excellent wash and light fastness, vibrant orange hues, and reliable batch-to-batch consistency for industrial-scale coloration. This product is essential for manufacturers in the textile industry seeking durable and brilliant coloration for cotton, wool, silk, and nylon fabrics.

Application

• Textile Dyeing: Primary application for exhaust and continuous dyeing of cellulosic fibers like cotton, viscose, and linen.
• Wool and Silk Coloration: Used for dyeing protein-based fibers, offering good levelness and color yield.
• Nylon Fabric Dyeing: Suitable for dyeing polyamide fibers to achieve bright orange shades.
• Garment Dyeing: Employed in batch dyeing processes for finished apparel and hosiery.
• Yarn Dyeing: Applied in the coloration of threads and yarns for weaving and knitting.
• Industrial Fabric Coloring: Used for coloring fabrics destined for automotive, upholstery, or other technical textiles requiring colorfastness.
