Description

C.I. Reactive Orange 69 is a high-performance, water-soluble reactive dye belonging to the azo chemical class. It is engineered for exceptional color fastness and brilliant orange hues on cellulosic fibers like cotton and viscose, making it a critical component for durable textile coloration. This product is essential for textile manufacturers, dye houses, and chemical distributors serving the global apparel and home furnishing industries who require reliable, vibrant, and wash-fast dyes.

Application

• Exhaust Dyeing of Cotton: Primary application for dyeing cotton yarns and fabrics in deep shades with excellent wash and light fastness.
• Continuous Dyeing Processes: Suitable for pad-batch and pad-steam dyeing ranges for efficient, large-scale fabric production.
• Viscose and Rayon Dyeing: Effective for coloring regenerated cellulosic fibers, providing bright and level shades.
• Blend Dyeing (Cotton/Polyester): Used in combination with disperse dyes for one-bath dyeing of cotton/polyester blends.
• Garment Dyeing: Applicable for batch dyeing of finished cotton garments to achieve uniform color penetration.
• Technical Textiles: For coloring cellulosic components in industrial fabrics where color consistency is paramount.
