从India供应商批量进口Acid Dye

Ophtha Dye supplies acid dyes from Ahmedabad, Gujarat, for dyeing protein and animal fibres including wool, silk, nylon and leather. The listing covers an extensive Colour Index range spanning Acid Brown, Acid Black, Acid Yellow, Acid Orange, Acid Red, Acid Violet, Acid Green and Acid Blue families with individual entries such as Acid Brown 14, Acid Black 1, Acid Yellow 3, Acid Orange 7, Acid Red 1, Acid Violet 5, Acid Green 16 and Acid Blue 9. Each dye is supplied with COA and MSDS documentation. The source indicates high wash fastness as a key performance property, with the dyes formulated as water-soluble anionic compounds containing large aromatic molecules that bind to cationic sites in fibre.

The typical chemical basis of acid dyes involves azo, anthraquinone, triphenylmethane or xanthene chromophores, depending on the colour family. Azo structures predominate in yellow, orange and red shades, while anthraquinone chemistry is standard for blues and greens. The dyes are generally sodium salts of sulfonic or carboxylic acids, giving anionic character and water solubility. Light fastness varies by structure: anthraquinone blues and alizarin-type dyes typically achieve 5-6 on the ISO Blue Scale, whereas certain yellow azo dyes may rate 3-4. Metal-complex acid dyes are standard alternatives where superior wet fastness is required. The listing does not specify whether these are levelling, milling or super-milling classes, so the buyer should confirm dyeing behaviour and compatibility with their substrate.

Buyers of Ophtha Dye's acid dyes include textile commission dyers, wool carpet manufacturers, silk weavers, leather tanneries and speciality ink formulators. The Ahmedabad location offers access to Gujarat's chemical manufacturing belt and Mundra or Kandla ports for export. The supplier states response data is currently at zero percent with no recorded response hours, so buyers should initiate contact to confirm active trading status, current stock levels, minimum order quantities and standard packaging formats. Acid dyes typically ship in 25 kg fibre drums or cartons; confirm with Ophtha Dye whether they offer smaller trial lots or bulk tanker dispatch for large volume orders.

Ophtha Dye is located at 29, Yogeshwar Apartment, Solaroad, Naranpura, Ahmedabad, Gujarat 380013, India. The supplier holds a harbor trust tier classification. The response rate is recorded at 0.00 percent with zero average response hours, which indicates no response activity is currently reflected in the platform data. Buyers should treat this as a signal to test responsiveness directly before committing to orders, and to verify whether the business maintains active operations or seasonal trading patterns.

The company profile contains no stated founding year, employee count, revenue figure, factory ownership details, or named clientele. No certifications such as ISO, GOTS, ZDHC or REACH compliance are listed in the source data. The product range is extensive across conventional acid dye chemistry, with documentation (COA and MSDS) offered for each colour index. Buyers should request specific batch consistency data, shade card samples, and confirmation of whether Ophtha Dye operates as a manufacturer, trader or agent, as this affects quality control and recourse in the event of non-conformance.
