Establishing Standard Mass Balance Scrap Tolerances across High Count Wet Spun Linen Runs
Fine count wet spun linen mass balance requires deducting 2.5 to 4.5 percent pectin dissolution loss and count-adjusted mechanical scrap from dry input mass.
Mill Weight Reconciliation
Material Accounting
Spinning mills track the inflow of raw flax and the outflow of spun yarn to calculate the overall material yield and waste percentages. Within the inventory control system, the mill weight reconciliation matches the raw material weights received at the warehouse with the dry weights processed through the spinning lines. This accounting step detects material loss from moisture evaporation and physical fibre waste during processing.
Reconciliation Process
Warehouse staff weigh every incoming bale of flax and compare this figure with the shipping manifest. This mill weight reconciliation uses the dry-weight values obtained from the oven-drying lab to calculate the true yield of the batch. If the combed sliver mass plus the collected combing waste is less than the raw bale mass, managers investigate the discrepancy.
This check reveals if moisture loss or fibre theft occurred during the initial storage period. If raw bales are left in dry storage for too long, they lose weight without any fibre being processed.
Process Control
Regular reconciliation helps the production manager evaluate the efficiency of the combing and spinning machinery. The mill records these weekly yields in the factory performance database. High yield figures prove that the hackling pins are not breaking the flax.
This verification ensures that raw material purchases remain cost-effective.
