Production Movement
A physical record accompanying specific quantities of flax fibre through mechanical cleaning and spinning operations tracks every stage of conversion into yarn. This batch traveller stays attached to the bins or pallets during movement between the carding machines and the spinning frames. It lists the raw material origin, the specific density of the fibre, and the assigned machine line.
Operators use the card to log throughput speeds and detected impurities observed during the initial refinement. The record effectively prevents the mixing of different harvests within the same spinning run. Accurate data on the document ensures that moisture levels remain within specified ranges during storage.
Measurement Standard
Grading criteria distinguish between the chemical properties of raw flax fibre and the physical strength metrics applied to woven linen cloth. A mill assigns a grade to fibre lots based on colour and length while cloth receives a rating determined by thread density and tensile resistance. Quality teams establish internal benchmarks for yarn regularity which differ from the acceptance criteria provided by a foreign buyer.
Buyers often demand a lower variance in thread diameter than local production protocols require. Discrepancies arise when the fibre grade meets internal targets but fails to satisfy the specific weight requirements of the finished export product. Verification occurs at each transition point where inspectors compare the current state of the material against the initial parameters recorded on the traveller.
Logistical Control
Finished reels awaiting export undergo a final assessment to determine if the processed lot aligns with the original delivery specifications requested by the weaver. Personnel confirm that the quantity recorded at the spinning frame matches the weight measured at the finishing dock. If a shipment contains rolls from different production cycles, the tracking document identifies the exact deviation for the client.
Mills rely on the continuity provided by these records to isolate contamination if a machine failure alters the tensile properties of the yarn. The final documentation provides an audit trail for liability when fibre quality disputes occur after delivery. The integrity of the supply chain depends upon the accuracy of these records during every stage of handling.
