Flax Fibre Bundle Separation and Staple Length Retention Fundamentals
Selective pectin degradation paired with tuned hackling pin density maximizes fibre bundle separation while retaining staple length for fine wet spinning.
Strick Clamp Pressure
Mechanical Compression
Pneumatic tension applied to flax fibre bundles during the hackling operation determines the efficiency of parallelization and the removal of short straw. The strick clamp pressure ensures that the fibres remain secure within the transport mechanism while travelling through the rotating steel pins of the hackling machine. Failure to maintain these force levels allows fibre slippage, which results in irregular combing and excessive waste generation.
This physical restraint maintains the integrity of the line length throughout the preparatory process before the final drafting stage in the spinning mill.
Operation Control
Operators monitor the load via load cells integrated into the hydraulic circuit to keep the force within specific Newton ranges required by the mill standard for top quality flax. Higher settings increase the grip on coarse fibre lots, whereas delicate hackled flax requires reduction to prevent surface abrasion or breakage of the individual strands. Sensors detect deviations from the programmed force and transmit data to the central production record for traceability.
Precise regulation of this force balances the need for maximum mechanical extraction against the risk of fibre degradation during the high-speed combing cycles.
Production Outcome
Constant grip settings define the consistency of the output fibre quality across the entire production batch. Variations in the applied force alter the degree of cleaning achieved by the pins, which directly changes the grade of the finished line. Consistent application of this force guarantees that the resultant fibre bundles meet the specifications requested by buyers for fine yarn spinning.
Proper adjustment at this station eliminates the risk of uneven fibre distribution during the later steps of the production flow.
