Widely used in textile dyeing, especially for cotton, rayon, and other cellulosic fibers, providing deep black shades with good color fastness. Commonly applied in the production of black-colored fabrics for apparel, home textiles, and industrial materials. Suitable for batch and continuous dyeing methods, including pad-dyeing and exhaust processes. Offers good leveling properties and moderate lightfastness. Frequently used in combination with other dyes to achieve specific black tones or to enhance dyeing performance. Also found in printing inks for textiles where intense black color is required.
