从India供应商批量进口Acid Black 210 - Black N.Spl / Nbh/Nt

Acid Black 210 (Black N.spl / Nbh/nt) is an acid dye formulated for wool, nylon, silk, paper, leather, and ink applications. The product is supplied by Karsandas Mavji from Mumbai, Maharashtra, India. The dye is available in multiple packaging options to suit different industrial requirements. Its formulation relies on acid-based chemistry to achieve stable attachment to protein and polyamide fibres. The Colour Index designation 210 places it within the acid black series used extensively across textile and allied industries. Buyers should confirm the exact dye content percentage and salt specifications with the supplier before ordering.

Acid dyes of this class typically contain azo or anthraquinone chromophores solubilised by sulfonic acid groups. The N.spl, Nbh, and nt variants denote shade or strength modifications tailored to specific substrate requirements. Standard industrial grades typically show solubility in water at 60-80°C, with optimum exhaustion on wool at pH 4.0-6.0. The dye's affinity for amine-terminated nylon makes it suitable for hosiery and carpet applications. Light fastness typically ranges from 4-6 on the ISO Blue Scale, though buyers should request the specific rating for this variant. The powder or granular physical form allows for accurate metering in automated dosing systems.

Primary buyers include woollen textile mills, nylon carpet manufacturers, leather tanneries, and specialty paper producers. The ink industry uses acid blacks for fountain pen and stamping ink formulations. Karsandas Mavji positions this dye for industrial-scale procurement with flexible packaging.
