Pattern Anomaly
Irregular insertions of weft yarns break the continuity of the weave structure and create visual horizontal bands across the fabric. Identifying mispicks occurs during greige inspection where the missing or extra threads disrupt the intended geometric sequence of the linen cloth. These flaws often arise from errors in the mechanical timing of the loom or faulty optical sensors at the nozzle.
Fabric Flaw
Inspectors search for patterns where the weft thread has failed to cross the full width or has duplicated inside a single shed opening. Detection of mispicks results in immediate tags for repair if the fabric value allows or a downgrading of the roll to second quality if the damage is widespread. Repairing these errors by hand involves carefully unpicking the yarns and re-weaving the section which increases the cost per meter significantly.
Consistent patterns of such errors suggest that the loom maintenance team needs to re-align the insertion mechanisms. Weavers look for specific machine signatures that repeat the error at fixed intervals.
Boundary Condition
Visibility depends on the contrast between the yarn density and the weave style, as looser weaves hide minor deviations more effectively than tight satins. A high frequency of mispicks ruins the suitability of linen for luxury garment production.
