Description

C.I. Direct Red 95 is a synthetic, water-soluble azo dye belonging to the direct dye class, known for its bright red color and strong affinity for cellulosic fibers. Its primary value lies in providing excellent wash and light fastness on cotton, viscose, and other natural fibers without the need for a mordant. This dye is essential for manufacturers in the textile industry seeking efficient and vibrant coloration for yarns, fabrics, and garments, and it also finds utility in the paper and leather industries.

Application

• Textile Dyeing: Primary application for exhaust and continuous dyeing of cotton, viscose, rayon, and other cellulosic fibers to achieve a bright red shade.
• Paper Coloring: Used in the surface coloring and tinting of paper products, including specialty papers and packaging materials.
• Leather Finishing: Imparts color to leather goods, providing a uniform and durable finish for various products.
• Ink Formulation: Serves as a colorant in the production of inks for specific printing applications.
• Biological Staining: Potential use as a histological stain in laboratory settings for microscopic analysis.
