Dye Lot
A dye lot is a batch of fabric or yarn dyed together in a single cycle. Each lot has slight shade variations that must be tracked for order consistency.
A dye lot refers to fabric or yarn dyed together in a single dyeing cycle using the same machine, recipe, and operator. Even with identical inputs, different lots produce slightly different shades due to water chemistry, temperature variance, and dyestuff batch-to-batch variation.
Buyers expect shade consistency within an order. Mixing dye lots within the same shipment causes visible shade variation in finished garments — a major cause of rejected orders in the textile industry.
Dye lot tracking is critical for: (1) allocating the right rolls to the right customers, (2) matching replacement orders, (3) maintaining traceability for quality issues, and (4) preventing shade-mismatch claims from export customers.
Generic ERP systems treat a fabric SKU as a single item. Textile-specific ERPs like TextileERP treat each dye lot as a distinct sub-SKU with its own shade coordinates, inventory balance, and allocation history.
