Line Flax Yield

Recovery Measurement

Percentage calculations of long fibre recovery measure the efficiency of the preparatory hackling and combing processes in flax mills. The line flax yield reflects the proportion of premium long fibres obtained from a given quantity of scutched flax intake. High yields indicate both superior raw material quality and precise mechanical adjustments.

Spinning mills record these percentages in their monthly performance logs to monitor processing efficiency.

Mechanical Influence

Operational settings on the hackling machine, such as pin density and combing speed, affect the extraction of long fibres. If the pin density is too high or the fibre is brittle, excessive breakage occurs, which reduces the output. Supervisors run small trial batches from each new flax shipment to establish the optimal machine configuration.

The resulting line flax yield determines the cost structure of the spun yarn batches. Adjustments are noted in the machine log to maintain consistent recovery rates across different shifts.

Cost Impact

Financial margins in linen spinning depend heavily on minimizing the generation of lower-value tow. Since line flax is the primary driver of revenue, a minor drop in its recovery can eliminate the mill’s profitability. Yarn contracts are priced based on the expected yield from specific grades of imported flax.
