Tension Imbalance
Sizing and warping operations in weaving mills must maintain uniform tension across the entire width of the yarn sheet to ensure a consistent weave structure. The warp crimp skew describes a localized imbalance where the crimp percentage of warp yarns varies systematically from one side of the fabric to the other. This variation usually results from uneven tensioning across the warp beam during the winding process.
Fabric Distortion
This uneven warp tension causes the weft yarns to bend or lie at an angle relative to the warp instead of running perpendicular. A fabric affected by warp crimp skew will distort when washed, leading to twisting in garments and uneven shrinkage during the finishing of linen cloth.
Quality Remediation
Industrial finishers measure the angular deviation of the weft yarns across the fabric width to identify this structural defect before the bleaching and dyeing stages. If the skew exceeds the tolerances set by the buyer, the fabric must be processed through a weft straightener equipped with skew-correction rolls. This mechanical correction pulls the low-tension warp sections to realign the weft yarns before the fabric is dried and set.
By resolving this imbalance early, the mill avoids costly rejections of finished linen rolls and maintains the structural integrity of the woven material.
