Sulphur Black Extra Pure is a high-quality sulfur-based black dye widely used in the textile industry for dyeing cellulose fibers such as cotton. It produces a deep, rich black color with excellent wash and light fastness. It is also utilized in leather dyeing, printing inks, and various industrial applications requiring durable black pigmentation. Sulphur Black is typically supplied as a fine powder or granules and requires alkaline conditions for effective dyeing. Proper handling to avoid dust inhalation and storage in a dry, cool environment is essential to maintain product quality.
