Verifying Raw Flax Traceability from Field to Scutcher
Verify raw flax origin by matching field cadastral logs to weighbridge moisture tickets, scope certificates, and scutching mass balance yield ratios.
Pull Harvesting
Harvest Mechanism
Uprooting harvest techniques extract entire flax plants from agricultural soil to preserve full stem length for textile fiber recovery. In primary flax cultivation, pull harvesting prevents length loss associated with conventional sickle or cutter bar harvesting methods. Specialized harvesting machinery grips standing flax stems between rotating rubber belts, lifting root systems intact out of the ground.
Stems are deposited in uniform horizontal swaths across the field to begin field retting. This field operation governs raw straw harvesting, ending once uprooted plants lie aligned in field windrows.
Fibre Preservation
Retaining taproots maintains maximal fiber length, directly increasing the proportion of valuable long line flax recovered during scutching. Cutting flax stems with traditional mowers leaves valuable fiber behind in root stubble, reducing long fiber yield by up to ten percent. Modern pull harvesting machinery operates at precise forward speeds to pull stems without snapping delicate stalks during extraction.
Aligned stems lie flat in windrows, facilitating uniform dew retting across top and bottom stem layers. Maximizing line fiber length during harvest enables spinning mills to produce fine, high-tenacity linen yarns required for premium woven textiles.
Agronomic Scope
Extremely wet soil conditions impair harvester belt traction, causing stem slippage and root breakage during pulling operations. Stony soils or heavily lodged crops increase mechanical strain on gripper belts, requiring reduced field speeds to avoid crop loss. Pull harvesting applies exclusively to bast fiber crops harvested for spinning, offering no practical function for grain or seed crops.
