Sulphur Black is a synthetic sulfur-based dye renowned for its deep black color and excellent fastness properties, especially on cellulose fibers like cotton. It is widely used in textile dyeing due to its cost-effectiveness and ability to produce dark, durable black shades. Sulphur Black is insoluble in water but applied through a reduction process that allows it to penetrate fibers and form insoluble pigments within the fabric, offering excellent wash and light fastness.
