Intake Weighbridge Cross Checking for Raw Flax Scutching Manifests
Intake weighbridge cross checking reconciles gross straw mass, core moisture regain, and soil tare against scutching manifests to verify net fibre yields.
Tow Extraction
Mechanical Separation
Mechanical separation governs the removal of woody core fragments from softened flax stalks during primary processing in Chinese linen mills. The procedure relies on high-speed fluted rollers that crush the dried inner stem while pneumatic systems draw away the resulting waste. Tow extraction defines the boundary where coarse residual fibre separates from long line flax before spinning frames receive the material.
Lower grade short staple output is separated by this mechanical action from the parallel ribbon strands destined for fine yarn production.
Fibre Grading
Line sorting follows immediately after cleaning operations conclude to establish market value through staple length measurement and tensile testing. Shorter extracted parcels receive distinct classification markers on mill floor dockets to differentiate them from combed line stock. Buyer acceptance standards demand specific cleanliness metrics that determine whether short fractions qualify for semi-wet spinning machinery or dry frame processing.
Export Specification
Documentation accompanying finished bales records residual woody content percentages established during laboratory testing phases prior to international shipment. Commercial contracts stipulate maximum allowable shive limits for short staple lots leaving the processing facility for overseas textile converters. Final verification certificates confirm that the delivered material meets the structural integrity requirements agreed upon between the mill operator and the foreign buyer.
