Physical Control
Separation of raw flax bales by harvest origin prevents cross contamination during retting and early scutching stages inside Chinese processing mills. Physical lot segregation ensures that inferior dew retted stems never mix with water retted material before spinning frames draw the roving into yarn. Mill supervisors mark each batch with specific chalk numbers on the bale ties to maintain visual boundaries across the workshop floor.
Workers transport segregated bins along painted floor paths toward the drafting machines. When humidity rises inside the wet spinning room, cellulose fibres swell and shift slightly within their assigned bays.
Batch Boundary
Separation lines must remain intact until quality inspectors sign the mill acceptance ledger after testing tensile strength. Fibre grades require distinct perimeter clearances from fabric grades to prevent stray lint from entering adjacent collection hoppers. Mill acceptance criteria demand zero tolerance for intermingled lots during carding operations, whereas buyer acceptance criteria permit minor variations if breaking length exceeds baseline thresholds.
Warehouse forklift drivers follow strict clearance rules when moving pallets away from the sorting tables. Inspectors record batch numbers inside the production logbook before yarn moves toward the weaving floor for loom preparation.
Origin Audit
Separation protocols govern how workers document material movement from the initial hackling bench through final export crating. Quality control officers verify lot boundaries against the accompanying shipping manifest during random daily audits. Internal mill standards dictate a minimum two metre gap between differing harvest batches, while external certification bodies require permanent physical barriers made of wire mesh partitions.
Workers stack bales according to density ratings rather than colour shades alone. Documentation accuracy depends entirely upon maintaining strict spatial discipline from the initial sorting station until finished linen bolts leave the loading dock.
