Sulphur Black 1, a pivotal dye in the textile and leather industries, is gaining significant attention for its robust performance and versatility. This dye, renowned for its deep, rich black shade, offers an indispensable solution for achieving durable and aesthetically pleasing coloration on various materials. As a leading raw material provider, NINGBO INNO PHARMCHEM CO.,LTD. is committed to delivering high-quality Sulphur Black 1 that meets the stringent demands of modern manufacturing processes.

Characterized by its appearance as flashing black flakes or granulars, Sulphur Black 1 is a compound with specific chemical properties. It is largely insoluble in water or ethanol, yet it exhibits a distinct green-black hue when dissolved in a sodium sulfide solution. Adding caustic soda to this solution shifts the color to bluish, while hydrochloric acid introduces a greenish precipitate. This intricate chemical behavior underscores its effectiveness as a dyeing agent. Furthermore, its ability to be directly dissolved in water without the prior addition of sodium sulfide marks a significant advancement, contributing to more efficient and environmentally conscious dyeing practices.

The application spectrum of Sulphur Black 1 is remarkably broad, making it a preferred choice across numerous sectors. It is extensively utilized for dyeing and winding dyeing processes on materials such as cotton, jute, viscose, polyvinyl alcohol fibers, and even certain polyester and polyamide fibers. Its particular suitability for rolling dyeing ensures consistent and uniform color penetration. Beyond textiles, Sulphur Black 1 also finds application in paper dyeing, standing out as one of the most environmentally protective dyes available for this purpose. Its strong dye-uptake and excellent level dyeing properties ensure a superior finish, making it a reliable option for manufacturers striving for quality and consistency.
