Description

Reactive Red 111 is a high-performance, water-soluble azo dye belonging to the reactive dye class, designed for covalent bonding with textile fibers. Its primary value lies in producing vibrant, wash-fast red shades on cellulosic materials like cotton and viscose, ensuring excellent color yield and reproducibility. This dye is essential for textile mills, dye houses, and industrial manufacturers seeking reliable and efficient coloration for fabrics, yarns, and garments.

Application

• Exhaust Dyeing of Cotton: Primary application for dyeing cotton yarns, knits, and woven fabrics in batch processes.
• Continuous Dyeing: Used in pad-batch and pad-steam processes for efficient, large-scale fabric production.
• Viscose/Rayon Coloration: Effective for dyeing regenerated cellulosic fibers to achieve bright red hues.
• Textile Printing: Suitable for printing applications on cellulosic substrates to create patterned designs.
• Blend Dyeing: Can be used in formulations for dyeing cotton blends with other fibers like polyester.
• Leather Dyeing: Applied in the coloration of certain types of leather goods.
