Description

C.I. Reactive Violet 24 is a high-purity, reactive dye belonging to the vinyl sulfone class, known for its excellent color fastness and brilliant violet hue. This compound is essential for achieving durable and vibrant coloration on cellulosic fibers like cotton and viscose. It is a critical raw material for textile dyeing and printing operations, as well as for manufacturers of specialty inks and colorants. Global industries rely on its consistent quality for producing colorfast textiles and other dyed materials.

Application

• Textile Dyeing: Primary application for exhaust and continuous dyeing of cotton, linen, and other cellulosic fabrics.
• Textile Printing: Used in printing pastes for creating sharp, wash-fast violet designs on garments and home textiles.
• Leather Coloring: Imparts vibrant and durable violet shades to finished leather goods.
• Paper Staining: Employed for specialty paper coloring where high color intensity is required.
• Ink Formulation: A key component in the manufacture of certain types of industrial and specialty inks.
• Research & Development: Serves as a standard or intermediate in chemical research and dye synthesis laboratories.
