Fibre Ratio
Total post-processing mass divided by raw input mass determines the recovery rate of botanical filaments. Dry mass yield quantifies the loss of moisture and non-fibrous vegetable matter during the scutching and hackling phases of flax preparation. Technicians calculate this metric by weighing the raw straw before retting and measuring the resulting clean line fibre after removing impurities.
It acts as the primary benchmark for assessing the efficiency of the mechanical separation process.
Production Benchmark
Clean fibre output provides the fiscal basis for mill contracts between agricultural cooperatives and textile manufacturers. High-grade batches require consistent results to ensure that spinning frames receive a uniform density of material per spindle hour. Buyers stipulate a minimum percentage to mitigate the risk of hidden moisture or excessive shive content within a bale.
Mills adjust their equipment settings to maximize this value while maintaining the structural integrity of the individual filaments. Variations in crop maturity or soil composition cause fluctuations in raw straw quality that dictate the ultimate percentage of usable output.
Grading Protocol
Quality control records track the net recovery of processed material against the gross intake weight of each harvest lot. Examiners measure the dry mass yield on samples taken from every pallet to confirm that the fibre meets established commercial standards for export. A divergence from the expected ratio triggers an investigation into the drying temperature or the intensity of the mechanical beating process.
Uniformity in this measurement guards the profitability of the mill while providing the purchaser with a predictable quantity of raw material for the looms.
