从India供应商批发进口Acid Red 249 Dyes — FOB条款

Acid Red 249 is a synthetic acid dye identified by CAS number 6416-66-6, also known in the industry as Acid Milling Red 2B. This product is supplied by Sparrowings International from Gujarat, India, in powder form. Its molecular formula is C29H20ClN3Na2O10S3, and it carries the EINECS number 229-129-2, confirming its registration under European chemical inventories. The dye is classified as an acid dye, primarily used for textile applications, particularly in polyamide materials.

The chemical structure of Acid Red 249 includes a sodium sulfonate group, which enhances its solubility in water, a critical property for dyeing processes. Acid dyes like this one are known for their ability to form ionic bonds with amino groups in fibres such as wool and nylon, resulting in vibrant, colourfast results. Typical industry standards for such dyes include a minimum dye content of 85 percent, with moisture content usually below 5 percent to ensure stability and performance. Standard purity tests often involve spectrophotometric analysis to confirm colour strength and consistency.

Acid Red 249 is widely used in the textile industry for dyeing polyamide fibres, including nylon, as well as in blended fabrics. Importers typically source this dye for applications in apparel, carpets, and technical textiles where colour consistency and wash fastness are essential. Buyers should confirm the dye’s compatibility with their specific fibre types and processing conditions. Trade terms such as packaging in 25 kg fibre drums, MOQ, and lead times should be verified directly with Sparrowings International, as these are not specified in the listing.

Sparrowings International is based in Ahmedabad, Gujarat, India, with its office located at D-101, Maruti Homes, Opp. Shreenath Elegance, Nana Chiloda, 382330. The supplier specialises in textile dyestuffs, including acid dyes such as Acid Red 249. The listing does not provide details on the company’s scale, history, or additional product lines, but its focus on dyes for polyamide applications suggests a niche in synthetic fibre colouration.

As a supplier, Sparrowings International operates under the ‘harbor’ trust tier, which indicates a baseline level of verification. However, the response rate and average response hours are currently listed as 0.00, which may suggest limited recent activity or a need for buyers to follow up directly. The absence of additional verification signals or client references means importers should request samples and certifications to confirm the dye’s quality and compliance with their requirements.
