Direct Orange 37 is a direct dye with CAS number 1325-61-7, supplied as a fine powder by Sparrowings International from Gujarat, India. It is identified in industry references as Light Fast Orange 4R and is used primarily for dyeing leather, paper, and textiles. The product is delivered in dry, free-flowing form with no visible clumping or moisture retention as reported in the source data.
This dye belongs to the azo class of direct dyes and is typically applied under alkaline conditions in hot water baths. Standard industry practice for textile applications involves a liquor ratio of 1:15 to 1:20 and a dyeing temperature range of 80°C to 95°C. The dye exhibits moderate light fastness, typical for direct orange dyes in this chemical class, and is not recommended for outdoor applications requiring high UV resistance.
Buyers in the leather finishing, paper coating, and textile printing sectors source this product for batch dyeing where cost-effective coloration is prioritized over extreme durability. The dye is compatible with cellulose-based fibers and protein substrates like wool and silk. Packaging is typically in 25kg polyethylene-lined kraft bags, though custom packaging may be requested. Trade terms are not specified in the listing and must be confirmed directly with the supplier.

Before ordering Direct Orange 37 from Sparrowings International, verify the batch consistency of color strength and solubility through small-scale lab tests. Confirm that the dye meets your substrate's dyeing requirements, especially if used on blended fabrics or coated leather. Request a sample batch and test for color reproducibility across multiple dyeing cycles.
Logistics and lead time are not stated. Confirm Incoterms (likely FOB Mumbai or Ahmedabad), packaging weight per container, and whether the supplier handles export documentation. Payment terms are typically 30% advance with balance against copy of B/L, but this must be negotiated directly. Lead time for production and shipment should be confirmed in writing.
For quality assurance, require a Certificate of Analysis for each shipment covering CAS number confirmation, moisture content, particle size, and absence of heavy metals. Inspect packaging for integrity upon arrival, and store in a dry, ventilated area. Retain a sample of each batch for future reference in case of batch-to-batch variation complaints.
