Description

Reactive Yellow 168 is a high-performance, bifunctional reactive dye designed for vibrant and durable coloration of cellulosic fibers. Its core value lies in delivering excellent wash and light fastness properties, ensuring long-lasting color integrity in demanding applications. This dye is essential for textile manufacturers and dye houses seeking reliable, high-quality yellow shades for cotton, viscose, and other natural fabrics. Its reactive nature allows for strong covalent bonding with the fiber, resulting in brilliant, colorfast textiles.

Application

• Exhaust dyeing of cotton yarns and fabrics.
• Continuous pad-batch and pad-steam dyeing processes for cellulosics.
• Printing applications on cotton and viscose substrates.
• Dyeing of viscose rayon and linen for apparel and home textiles.
• Used in the production of towels, bed linens, and denim.
• Suitable for dyeing blends where the cellulosic component requires coloration.
