Acid Orange 156 is a synthetic acid dye with the CAS number 68555-86-2, also marketed under the name Weak Acid Orange 3G. This water-soluble powder, produced by Sparrowings International in Gujarat, carries the molecular formula C21H19N4NaO5S and EINECS number 271-462-0. It is specifically formulated for dyeing polyamide fibres, offering strong colour uptake with typical stability in acidic to neutral pH ranges.
The dye appears as a fine, free-flowing powder with standard particle sizes for industrial dyes, ensuring consistent dissolution in aqueous solutions. Acid dyes like this are known for their brightness and resistance to bleeding in polyamide applications, with typical lightfastness ratings between 4 and 6 on the ISO 105-B02 scale. The chemical structure includes sulfonic acid groups, which enhance solubility and fibre affinity, while the azo chromophore delivers the characteristic orange hue.
This product is primarily used in textile manufacturing for nylon, wool, and silk, where colour consistency and fastness are critical. Buyers typically source it in 25 kg or 50 kg multi-layer paper bags with inner plastic lining to prevent moisture absorption. For bulk orders, confirm minimum order quantities and lead times directly with Sparrowings International, as these are not specified in the listing. The dye is compatible with standard dyeing machinery and requires controlled temperature and pH to achieve uniform results.
