Description

Reactive Orange 16 is a highly reactive, water-soluble azo dye belonging to the vinyl sulfone class of reactive dyes. Its primary value lies in its ability to form strong covalent bonds with cellulosic fibers like cotton and viscose, resulting in excellent wash and light fastness properties. This dye is essential for textile manufacturers and dye houses seeking vibrant, durable orange to red-orange shades. It is also utilized in the coloration of leather and paper.

Application

• Textile Dyeing: Primary application for exhaust and continuous dyeing of cotton, viscose, linen, and other cellulosic fibers.
• Textile Printing: Used in printing pastes for creating sharp, fast orange prints on cellulosic fabrics.
• Leather Coloring: Imparts durable orange hues to leather goods.
• Paper Coloring: Employed for tinting paper products where color fastness is required.
• Research & Development: Serves as a standard or intermediate in chemical synthesis and dye research.
