Description

Vat Orange 15 is a high-performance vat dye belonging to the anthraquinone chemical class, known for its excellent color fastness and stability. This compound is essential for achieving durable and vibrant orange to reddish-orange hues on cellulosic fibers like cotton, linen, and viscose. It is a critical material for textile manufacturers, leather tanneries, and specialty ink producers who require superior light, wash, and rubbing fastness in their finished products.

Application

• Textile Dyeing: Primary application for dyeing and printing cotton, linen, rayon, and other cellulosic fabrics to achieve fast orange shades.
• Leather Coloring: Used in the dyeing of leather goods, providing rich, durable color for upholstery, apparel, and accessories.
• Specialty Inks: A pigment source for high-quality printing inks where color permanence and chemical resistance are required.
• Paper Staining: Employed for coloring specialty papers, including decorative and security papers.
• Batch Dyeing of Yarn: Ideal for exhaust dyeing processes of yarns and threads intended for high-wear applications.
• Industrial Fabric Coloring: Used for dyeing canvas, tarpaulins, and other industrial textiles exposed to outdoor conditions.
