Description

Reactive Orange 116 is a high-performance, water-soluble azo reactive dye designed for vibrant and durable coloration. It is valued for its excellent wash and light fastness properties, ensuring long-lasting color integrity on cellulosic fibers. This dye is essential for textile manufacturers and dye houses seeking reliable, high-quality orange shades for cotton, viscose, and other natural fabrics. The compound is identified by the CAS registry number 149315-84-4.

Application

Reactive Orange 116 is primarily used in the textile industry for dyeing and printing applications. Its key uses include:

• Exhaust Dyeing of Cotton: For uniform and deep shade development in batch dyeing processes.
• Continuous Dyeing: Applied in pad-batch and pad-steam processes for efficient, large-scale production.
• Textile Printing: Used in printing pastes for creating sharp and vivid patterns on cellulosic fabrics.
• Viscose and Linen Dyeing: Effective for dyeing other cellulosic fibers beyond cotton.
• Garment Dyeing: Suitable for dyeing finished apparel items to achieve specific color requirements.
