Tensile Resistance
Mechanical strength measured by the maximum load a single filament can bear before breaking governs the performance of raw flax during subsequent textile processing stages. This material property, known as single fibre tenacity, is evaluated using tensile testing instruments at the mill’s laboratory prior to the combing stage. Laboratory technicians document the breaking force in the raw fibre analysis sheet to determine the appropriate spinning limits.
Process Efficiency
High single fibre tenacity allows the fibre bundles to endure the intense mechanical stresses applied during the drafting and drawing processes. Fibres with low tenacity break frequently under the drawing rollers, creating short fragments that increase the yarn’s hairiness and reduce the overall efficiency of the spinning frame. This breakage leads to an increase in the proportion of short-staple tow, which lowers the commercial value of the processed flax lot.
Fabric Durability
Weavers demand a guaranteed level of raw fibre strength to ensure the finished fabric can withstand the abrasion and tension of both industrial weaving and final consumer use. The mill’s quality assurance team compares the average single fibre tenacity against the buyer’s acceptance criteria to approve the shipment for export. This strength profile is recorded on the raw material compliance certificate, which serves as the official release document for the yarn spinning run.
It guarantees that the finished linen fabric will retain its structural integrity under severe mechanical wear.
