Import Acid Green 73 — Buy in wholesale FOB from Supplier in India

Acid Green 73 is a powder-form acid dye offered by Sparrowings International from Ahmedabad, Gujarat, identified chemically by CAS number 12219-93-1 and the alternate name Lanacron Olive G. The dye is classified for use on leather, textile fibres, and specifically polyamide fibre dyeing, distinguishing it as a versatile colourant for protein and synthetic amide substrates. Its physical presentation as a dry powder supports accurate dosing in automated colour kitchens and manual weigh-dispense operations alike.

This dye belongs to the acid dye class characterised by sulphonated groups that confer water solubility and affinity for cationic sites on wool, silk, and nylon under acidic conditions. The Lanacron designation indicates a standardised colour index name associated with a specific shade position in the green spectral range. Typical commercial Acid Green 73 exhibits aColour Index constitution number in the acid green series, with molecular weight generally in the 600-700 g/mol range for this structural family. Standard manufacturing yields a free-flowing powder with controlled moisture content to prevent agglomeration during storage in tropical conditions.

Polyamide fibre dyeing represents a primary outlet for this grade, particularly in carpet and hosiery applications where level dyeing properties and moderate fastness to washing and light are required. Leather tanneries value acid greens for their brightness on chrome-tanned substrates. Textile applications on wool span from loose fibre to piece goods. Buyers should note that polyamide dyeing with Acid Green 73 typically requires pH control between 4.0 and 6.0, with temperature rise from 40°C to boil over 30-45 minutes to achieve level results. Sparrowings International should be consulted for specific bath formulation recommendations and compatibility with retanning agents or fibre finishes.
