Among the various forms, Sulphur Black BR stands out for its specific bluish-reddish undertone, offering a versatile base color. High-strength versions, such as Sulphur Black BR with 220% concentration, provide greater dyeing efficiency and intensity.
Our offering focuses on this premium Sulphur Black BR 220%, presented in a convenient granular form. This granular structure minimizes dust, improving handling and safety in the dye house. It is primarily utilized for achieving deep, rich black tones on cotton fibers, but is also effective on blends containing viscose, cambric, and certain vinyls, making it a versatile choice for manufacturers.
The high 220% strength ensures that less dye is required to achieve the desired depth of shade, leading to potential cost savings and reduced inventory requirements for large-scale textile production.
Chemically identified by CAS number 1326-82-5, Sulphur Black BR has the molecular formula C6H4N2O5 and EINECS number 215-444-2. Key specifications typically include a strength of 220%, moisture content below 2.9%, water insoluble matter less than 0.5%, free sulphur content around 0.31%, and a fineness (screening hangover on 80 um) less than 3%.
Its characteristic solubility profile involves insolubility in water and ethanol, dissolving readily in sodium sulfide solution to yield a greenish-black color. Reactions with caustic soda or hydrochloric acid produce distinct color changes or precipitates, which are indicative of its chemical nature.
Dyers appreciate Sulphur Black BR for its reliable performance, including good dye-uptake and excellent level dyeing properties, which are crucial for uniform coloration across large fabric batches. The resultant black shades exhibit satisfactory light and wash fastness for many end uses, including popular items like denim jeans.
Its affinity for cotton makes it a staple in apparel and home textile manufacturing where durable and cost-effective black coloration is required. The stability of the granular form contributes to its ease of storage and accurate dispensing in automated dyeing processes.
Securing a consistent supply of high-quality Sulphur Black BR 220% is essential for textile manufacturers aiming for reliable production. Finding a trustworthy sulphur black manufacturer or sulphur black supplier directly impacts the quality and cost-effectiveness of dyeing operations.
