从China供应商批量进口Acid Black 172

Acid Black 172 is a synthetic organic dye with the molecular formula C40H20N6O14S2Na2Cr and a molecular weight of 970.68 g/mol, supplied as a black even powder. It is water soluble, enabling uniform dispersion in dye baths for consistent colour uptake in textile and leather applications. The dye’s chemical structure ensures stability under typical dyeing conditions, with chromium complexes providing strong affinity to protein and polyamide fibres.

This dye is classified as an acid dye, a category widely used in the textile industry for colouring wool, silk, nylon, and blends where vibrant, fast shades are required. Its deep black hue is achieved through controlled synthesis, with purity levels that meet industrial standards for colour consistency. Typical applications include piece dyeing, yarn dyeing, and printing, where its resistance to washing and light exposure is a key performance factor.

Textile manufacturers and leather finishers source Acid Black 172 for its reliability in producing dark, uniform shades across large batches. It is packed to protect against moisture and contamination during transit, with standard packaging options including 25 kg multi-wall paper bags lined with polyethylene. Buyers should confirm compatibility with their specific fibre types and dyeing processes, as performance can vary with pH and temperature parameters.
