Description

C.I. Reactive Red 16 is a high-performance, water-soluble azo dye belonging to the reactive dye class, primarily used for coloring cellulosic fibers. Its core value lies in its ability to form a strong covalent bond with the fiber substrate, resulting in excellent wash and light fastness properties. This makes it a critical component for manufacturers in the textile industry seeking vibrant, durable red shades on cotton, viscose, and other natural fabrics. Its reliable performance is essential for producing high-quality, colorfast apparel and home textiles.

Application

• Primary dyeing and printing of cotton fabrics for apparel and home textiles.
• Coloration of viscose (rayon) and other regenerated cellulosic fibers.
• Used in exhaust dyeing processes for yarns and garments.
• Application in continuous dyeing ranges for large-scale fabric production.
• Suitable for textile printing pastes to create sharp, defined patterns.
• Can be used in combination with other reactive dyes to achieve a broad spectrum of shades.
