Description

C.I. Reactive Orange 11 is a high-performance, water-soluble azo-based reactive dye designed for permanent coloration of cellulosic fibers. Its primary value lies in forming a covalent bond with the fiber, resulting in exceptional wash and light fastness properties. This dye is essential for textile manufacturers and dye houses seeking vibrant, durable orange to red-orange shades on cotton, viscose, and other natural fabrics.

Application

• Exhaust Dyeing of Cotton: Primary application for dyeing yarns, knits, and woven fabrics in jet, overflow, and beam dyeing machines.
• Continuous Dyeing Processes: Used in pad-batch and pad-steam ranges for efficient, high-volume fabric production.
• Viscose and Rayon Coloration: Provides bright and level shades on regenerated cellulose fibers.
• Union Dyeing: Effective for dyeing blends of cotton with other fibers under controlled conditions.
• Garment Dyeing: Suitable for achieving fashionable, uniform colors in finished apparel items.
• Technical Textiles: Used for coloring industrial fabrics where colorfastness is a critical requirement.
