Sulphur Black Product Details
Product Description
Sulphur Black, also known as Sulphur Black 1, is a widely used sulfur dye primarily applied in textile dyeing processes. It is available in powder, granular, and liquid forms, offering deep black shades with excellent color fastness. Sulphur Black is known for its affordability, good solubility, and ease of application in cotton and cellulose fiber dyeing. It provides a high level of wash, light, and rubbing fastness, making it an ideal choice for denim, cotton fabrics, and various industrial textiles.
Production Process
Sulphur Black is synthesized through a multi-step process, ensuring high purity and performance:
- Oxidation: Aromatic compounds, such as aniline or other sulfur-containing organic compounds, undergo oxidation to produce the dye.
- Sulfurization: The oxidized compounds are treated with sulfur or sodium polysulfide under controlled conditions to achieve the desired black dye.
- Filtration and Drying: The dye is filtered, purified, and dried into a stable form (powder, granules, or liquid) suitable for industrial applications.
- Quality Control: The final product is tested for purity, strength, and shade consistency before packaging and distribution.
