Fibre Classification
A scutcher long flax refers to the specific bundle of bast fibre stalks processed through mechanical beating to remove woody residue while preserving the length of the primary stem. This scutcher long flax product represents the highest category of output during the primary mechanical separation phase within Chinese linen production facilities. Mills monitor the purity of these stalks through a standardized examination of residual shive content after the initial beating process concludes.
Technicians grade the fibre based on the reach of the parallelized strands rather than assessing the density of the individual plant units. Buyers demand this classification because the extended length determines the efficiency of subsequent wet spinning lines. Mechanical beaters remove the bark from the woody core to isolate these lengths for commercial sale.
Fibre density remains high in this category relative to the waste fragments recovered from the floor of the machine. The length of the raw material dictates the spinning performance in downstream textile manufacturing.
Production Parameter
Operations at the facility rely on the mechanical separation settings applied to the raw plant stock as the machine strikes the stalks to release the fibre. Adjusting the impact force prevents the breakage of the long strands during the transit through the cleaning rollers. Operators log the quality outputs in the facility production ledger to track the yield against the incoming load of raw flax.
Consistency in the beating action ensures that the scutcher long flax maintains its structural integrity prior to the drafting stage of spinning. Differences in humidity within the mill shed the fibre strength during the sorting process. Humidity control units regulate the moisture content to keep the brittle bundles from snapping.
Sorting these bundles follows the inspection of the fibre bundles by automated optical sensors.
Export Specification
Shipping documents for textile raw materials categorize the scutcher long flax under specific customs codes that define the tariff and inspection requirements for international transit. International buyers check the lot samples against the contractual moisture allowance to ensure weight accuracy upon receipt. Mill owners label each crate with the harvest origin and the machine run identification for traceability.
Fibre lots that deviate from the length specification undergo a secondary reclassification to shorter staple categories. Quality control protocols distinguish the long fibre from the byproduct of short tow used in lower grade textile fabrication. Precise mechanical separation of the stalks governs the market valuation of every bale.
