Abrasion Injury
Visual irregularities in the fabric surface caused by excessive rubbing between the yarn and machine components appear as fuzziness or broken filaments. Loom friction defects occur when the protective sizing on the linen warp is stripped away by the reed or the heald eyes. This damage creates a localized weakness that can lead to holes or thin spots in the final cloth.
Mechanical Origin
Misalignment of the loom parts often forces the yarn to travel along an abrasive path rather than a smooth one. When loom friction defects appear in a repeating pattern, it suggests that a specific component like a guide roller or a needle is worn and requires replacement. Technicians inspect the yarn path to find the exact point where the flax is being degraded.
Worn reeds or scratched guide bars act as sandpaper against the delicate natural fibres. Regular polishing of all metal contact points is the primary method used to prevent these flaws from developing during long weaving cycles.
Quality Grading
Finished linen is inspected for these marks to determine if the roll meets the standards for first-grade export quality. Extensive loom friction defects result in the downgrading of the fabric to seconds or its total rejection by the garment manufacturer. Preventing these flaws requires constant monitoring of the loom’s mechanical state and the yarn’s lubrication level.
