Bundle Composition
Flax fibre grading defines the physical arrangement of individual stalks into primary shipping units. Bundle mechanics governs the alignment of these stalks within a manual grip before the application of wire or cord ties. This technical practice dictates the uniform distribution of density across the cross section of a unit.
Correct internal tension prevents the loss of shorter fibres during transit and handling. Equal stalks ensure that the moisture content stays stable within the stack by limiting air gaps.
Tension Regulation
Manual sorting operations require specific force to tighten the binding material around the fibre mass. Friction between individual stalks provides the resistance that maintains the shape of the unit after the release of the compression machine. Variations in the binding pressure alter the stability of the stack during export loading.
A loose constraint permits the shifting of interior stalks which degrades the quality of the fibre over time. Excessive force damages the outer layer of the flax by crushing the protective epidermis. Consistent application of this force keeps the stalks parallel and prevents the formation of internal tangles that complicate the spinning process at the destination mill.
Grade Classification
Acceptance criteria for imported bales rely on the integrity of the binding method established at the point of origin. Inspectors verify that the configuration of the internal bundle matches the density specifications set by the purchasing contract. A standard deviation in the mass per unit volume signals a failure in the mechanical assembly of the fibre.
Any deviation from the established packing geometry leads to a reclassification of the batch into a lower commercial grade. Precise mechanical control of the bundle represents a necessity for maintaining the technical value of flax throughout the global logistics chain.
