Weft Distortion
The misalignment of weft yarns relative to the warp direction appears as curved or diagonal patterns across the width of the woven cloth. In linen production, fabric skew and bowing are common defects that occur during the tentering and wet-finishing processes. This distortion must be corrected before the fabric is rolled and packed for export.
Inspection teams evaluate these defects against the buyer’s quality standards using standard measuring frames.
Finishing Adjustment
Unequal tension across the tenter frame causes the weft yarns to pull to one side or bend in the middle of the fabric run. High-speed finishing lines use automatic optical sensors to detect fabric skew and bowing and adjust the guiding rollers in real time. This correction is critical for linen because flax fibers do not easily deform once they are dried and heat-set.
If the distortion is not corrected, the linen fabric will twist and warp during garment cutting and sewing, leading to rejected product batches, which are recorded on the final quality inspection report before dispatch from the mill.
Garment Quality
Garment makers enforce strict limits on the maximum allowable weft distortion to ensure straight seams in finished linen apparel. This limit is set at a maximum of three percent of fabric width in standard buyer agreements. Passing this test ensures the fabric is suitable for high-end garments.
