Description

Vat Black 29 is a high-performance vat dye belonging to the anthraquinone class, renowned for its exceptional color fastness and deep, rich black shade. Its primary value lies in providing superior resistance to light, washing, and chlorine bleaching, making it a critical component for demanding textile applications. This pigment is essential for manufacturers in the textile dyeing and printing industries, particularly for coloring cotton, viscose, and other cellulosic fibers where long-lasting color integrity is paramount.

Application

• Primary dyeing of cotton, viscose, and other cellulosic fibers.
• Printing inks for textiles requiring high lightfastness.
• Production of high-quality denim and other workwear fabrics.
• Coloration of yarns and threads for automotive and home furnishing textiles.
• Used in combination with other vat dyes to achieve complex, deep shades.
• Applications in the dyeing of paper and specialty pulps.
