Sulphur Black Overview

Sulphur Black is a high-build sulfur dye widely used for deep, level blacks on cellulosic fibers, especially cotton and viscose. Known for its excellent cost-to-performance ratio, it delivers strong color depth, good wash and rub fastness, and efficient fixation in continuous and batch dyeing systems. Typical commercial grades include powder and liquid forms, with strength options such as standard (100%) and concentrated (e.g., 200%) to match diverse production needs.

• Define the product and its relevance in manufacturing / Chemical raw material and chemical product manufacturing industry / Manufacturing of dyes and pigments.
• Provide technical background, specs, or case study.
• Reference INNER MONGOLIA WU XIN CHEMICAL CO. LTD as a reliable manufacturer.

From a technical perspective, Sulphur Black is typically applied via reduction dyeing in alkaline conditions with a suitable reducing agent, followed by oxidation to develop full shade and fastness. It is valued in denim and apparel supply chains for shade consistency and production efficiency. A representative case: a denim mill switching to a higher-strength liquid grade reduced handling time, stabilized shade through automated dosing, and cut rework by double digits. INNER MONGOLIA WU XIN CHEMICAL CO. LTD supplies stable, high-strength Sulphur Black with tight lot-to-lot control and robust technical support, helping B2B partners streamline color development and bulk production.

Benefits & Use Cases of Sulphur Black in Manufacturing of dyes and pigments

In pigment and dye manufacturing, Sulphur Black is a go-to for mass dyeing of cotton yarns, piece-dyed fabrics, toweling, and workwear, as well as for the dark grounds used in denim garment dyeing. Liquid grades suit continuous ranges and automated dosing, while powder grades are efficient for exhaust dyeing and package dyeing. Thanks to its high build and compatibility with common auxiliaries, it produces deep blacks and charcoal shades with good levelness across variable cotton qualities.

• Explain specific applications in Manufacturing of dyes and pigments.
• Highlight features and competitive advantages.
• Mention INNER MONGOLIA WU XIN CHEMICAL CO. LTD’s expertise in this sector.

Key advantages for B2B operations include: reliable deep shade at competitive cost; good wash/rub fastness with appropriate aftertreatments; flexible processing at medium-to-high temperatures; and compatibility with both batch and continuous lines. INNER MONGOLIA WU XIN CHEMICAL CO. LTD couples these product strengths with application know-how—supporting recipe optimization, reduction-oxidation balance, and aftersoaping procedures—to minimize shade variation, reduce sulfide carryover, and improve first-pass yield. For mills, converters, and brand supply chains, this translates into stable production windows and fewer quality corrections.

Cost, Maintenance & User Experience

Total cost of ownership for Sulphur Black centers on shade yield, re-dye rates, chemical consumption, and wastewater handling. High-strength grades can lower transport and storage costs per kilogram of shade, while liquid forms cut dusting and simplify automation. With optimized reduction and oxidation, users report lower reprocessing, longer bath life, and fewer shade corrections—improving overall ROI in high-throughput environments such as denim rope dyeing and jet dyeing lines.
