Description

Vat Green 8 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 deep, durable green shades on cellulosic fibers like cotton, linen, and viscose, where superior wash and light fastness are critical. It is a key material for textile manufacturers, dye producers, and industrial colorant formulators serving the global apparel, home furnishing, and technical textiles markets.

Application

• Textile Dyeing: Primary application for dyeing and printing cotton, linen, rayon, and other cellulosic fabrics to produce fast green colors.
• Yarn Dyeing: Used in the batch and continuous dyeing processes for sewing threads, denim yarns, and other industrial yarns.
• Technical Textiles: Imparts color to fabrics requiring high durability, such as awning cloth, canvas, workwear, and military textiles.
• Leather Coloring: Employed in the dyeing of leather goods where color penetration and fastness are important.
• Pigment Manufacturing: Serves as a colorant intermediate for producing high-grade organic pigments and lakes.
• Paper Staining: Used for specialty paper coloring where high lightfastness is required.
