Widely used in the textile industry for dyeing cotton, linen, and other cellulosic fibers, especially in the production of black-colored fabrics. Commonly applied in the manufacturing of denim, uniforms, and workwear due to its excellent lightfastness and wash-fastness. Frequently used in batch dyeing processes where high color durability is required. Also employed in the printing of textiles where consistent, deep black shades are needed. Suitable for fabrics subjected to frequent washing and exposure to sunlight, making it ideal for both apparel and home textiles.
