Fibre Verification
Acceptance standards for raw flax inputs define the maximum allowable moisture content and foreign matter percentages permitted before spinning commences within a facility. Annex 22 01 provides the measurement protocol for determining these specific quality thresholds upon arrival at the mill floor. Each batch requires testing against these established parameters to ensure consistent processing results during the mechanical scutching phase.
Humidity levels inside the storage warehouse influence the weight reading, so inspectors normalize data based on standard ambient conditions. This document dictates the allowable margin of error for non-fibre contaminants like plant debris or mineral particles found in a shipment. Precise adherence avoids machine clogging in the automated carding lines.
Testing Procedure
Practitioners extract samples from multiple layers of the compacted bale to form a representative composite for laboratory analysis. The technician weighs the initial mass on a calibrated scale before applying the thermal drying method described in annex 22 01 to remove all aqueous content. Measuring the weight loss after a fixed duration provides the exact percentage of water present in the stock.
Once dry, researchers separate remaining organic waste from the clean flax fibres manually to calculate the ratio of impurities by mass. Staff record these findings in the production ledger to facilitate inventory tracking. Managers utilize this verified data to determine the payout price for the supplier based on the net dry fibre yield.
Heavy contamination levels trigger a re-grading process or total rejection of the delivery.
Operational Compliance
Production output depends heavily upon the purity of raw materials entering the spinning stage. Annex 22 01 functions as the formal bridge between raw material procurement and the internal manufacturing requirements of the mill. Variations in moisture content distort the tension calculations during the final yarn formation, leading to snapped ends or uneven fabric density.
Consistent application of these checks prevents the introduction of low grade batches into high quality output runs. Uniformity at the intake stage ensures that downstream finishing processes maintain the structural integrity required for international export standards. The regulation limits the risk of hidden costs arising from poor initial raw material quality control.
