Description

Direct Brown 95 is a synthetic azo dye belonging to the direct dye class, valued for its strong affinity to cellulosic fibers without the need for a mordant. Its primary value lies in providing a cost-effective and durable brown coloration with good wash and light fastness properties. This product is essential for industrial operations in the textile, leather, and paper industries seeking consistent, high-volume dyeing solutions. We supply this dye in commercial quantities with a focus on batch-to-batch consistency to meet rigorous production standards.

Application

• Textile Dyeing: Primary application for dyeing cotton, viscose, rayon, and other cellulosic fibers in exhaust and continuous dyeing processes.
• Leather Coloring: Used for dyeing leather goods, providing uniform and penetrating color for products like upholstery, footwear, and accessories.
• Paper Staining: Employed in the production of colored papers, paperboards, and specialty packaging materials.
• Ink Formulation: Serves as a colorant in the manufacturing of inks for various printing applications.
• Wood Staining: Applied for coloring wood and wood-based products to achieve desired aesthetic finishes.
