Fibre Classification
Flax scutcher yield identifies the mass of spinnable long fibre extracted from raw stalks during primary processing. The cn/tex value denotes the weight in grams of one thousand metres of finished linen yarn after the spinning stage concludes. Mills calculate this metric to ensure the linear density remains uniform across production runs.
Technical specifications within the supply contract define the acceptable deviation from this baseline figure. Spinners monitor these results to adjust draw frames and maintain structural integrity in the resulting thread.
Processing Verification
Quality control personnel obtain cn/tex measurements by weighing conditioned spools under controlled humidity levels. Variation in these figures indicates mechanical slippage or uneven fibre drafting at the flyer head. The test requires a precision balance to measure the sample mass against the documented length.
Reports from the spinning room provide these data to the weaving department for tension calibration. Proper density control prevents yarn breakage during high-speed loom operation and preserves fabric consistency.
Acceptance Standard
Contractual compliance relies on cn/tex documentation to determine if the batch meets the requirements for intended textile applications. Buyers establish specific thresholds to distinguish light garment yarns from heavy industrial materials. Fabric manufacturers verify that the average density aligns with the finished product weight per square metre.
Discrepancies between the shipping manifest and mill records trigger a re-evaluation of the entire lot. Consistent adherence to these numerical standards prevents structural failure in downstream weaving.
