Description

Reactive Yellow 86 is a high-performance, water-soluble azo-based reactive dye designed for vibrant and durable coloration. Its primary value lies in its excellent wash and light fastness properties, ensuring long-lasting color integrity on cellulosic fibers. This dye is essential for textile manufacturers and dye houses specializing in cotton, viscose, and other natural fiber applications, where consistent shade and reliable performance are critical.

Application

• Exhaust dyeing and continuous dyeing of cotton fabrics and yarns.
• Pad-batch and pad-steam dyeing processes for viscose and rayon textiles.
• Coloration of cellulosic fiber blends with polyester or nylon.
• Used in the production of dyed threads for sewing and embroidery.
• Application in the garment dyeing industry for finished apparel.
• Suitable for use in textile printing pastes and inks.
