Sulphur Black is a widely utilized sulphur dye valued for its ability to impart deep, robust black shades with good color fastness. The BR variant specifically offers a Bluish-Reddish tone, allowing for nuanced color formulations. Available in granular or flake form, our Sulphur Black BR 200% is manufactured to facilitate easy handling, dissolution, and application within industrial dyeing processes.

The dye exhibits distinctive chemical characteristics. It is primarily insoluble in water and ethanol but demonstrates good solubility in sodium sulfide solutions, producing a characteristic green-black hue. Its reactivity with other chemicals, such as turning bluish with caustic soda, is well-documented. A notable feature of our Sulphur Black BR 200% is its capacity for direct dissolution in water without the compulsory addition of sodium sulfide, streamlining processing and potentially offering operational efficiencies.

Sulphur Black BR 200% is extensively applied in the dyeing and winding dyeing of numerous textile substrates. It performs exceptionally well on natural cellulosic fibers like cotton and jute, as well as regenerated cellulosic fibers such as viscose. Furthermore, it is effective on various synthetic fibers, including polyvinyl alcohol fibre, polyester, and polyamide fibre. This broad applicability makes it suitable for diverse dyeing techniques, including popular methods like rolling dyeing, where consistent shade and penetration are critical.
