从India供应商批发进口Acid Violet 1 — FOB条款

Acid Violet 1 is an anionic azo dye supplied as a powder by Sparrowings International from Gujarat, India, with CAS number 6441-91-4 and molecular formula C16H10N4Na2O9S2. The EINECS registration is 224-352-1. This acid dye is manufactured for application across leather, paper, and textile dyeing processes, with the powder form aiding dissolution in aqueous acidic baths typical of wool and nylon processing.

The dye chemistry relies on sulfonate groups that confer water solubility and affinity for protein and polyamide fibres through ionic bonding. Standard acid violet formulations in this class typically exhibit good levelling properties and moderate fastness to washing and light, though specific performance varies with substrate and after-treatment. The powder appearance indicates a standardised strength batch, typical for bulk industrial colourant supply where precise weighing and reproducible shade are required.

Textile mills, leather tanneries, and paper coating operations constitute the primary buyer base for this grade. The supplier offers the dye under their Sparrowings brand, positioned for industrial scale use rather than niche artisan applications. Buyers should confirm the exact colour strength, typically expressed as a percentage of standard, and verify whether the batch meets their required shade tolerance before committing to volume orders.

Sparrowings International is headquartered at D-101, Maruti Homes, opposite Shreenath Elegance, in Nana Chiloda, Ahmedabad, Gujarat, India, postal code 382330. The company operates from this Gujarat location, a state with established chemical and dye manufacturing infrastructure. The supplier profile indicates a harbour trust tier and a response rate of 0.00 percent, with no recorded average response hours, suggesting limited or unmonitored enquiry handling at the time of listing.

The listing presents Sparrowings International as a manufacturer and exporter of acid dyes, specifically branding this Acid Violet 1 under their own name. No additional certifications, production capacity figures, year of establishment, or client references are stated in the available data. Buyers should verify direct manufacturing capability versus trading activity, request current production batch data, and confirm quality control protocols before reliance on supply continuity.
