Warp Tension Equalisation Across Hook Groups
topic
Jacquard warp tension equalisation addresses the different warp consumption rates of ends in different positions of the design repeat from the varying frequency with which each end is raised according to the design programme, with high-density dark areas of the design raising more warp ends per pick consuming more warp length than light areas, creating differential consumption that progressive tension variation across the warp width without compensation by tension-sensitive let-off systems that detect and correct position-specific tension divergence.
Role
Prevents the progressive warp tension non-uniformity across the fabric width that design-driven differential consumption creates in complex figured weaving, with tension equalisation being particularly critical for fine Jacquard fabrics where small tension differences create visible weft density variation that manifests as background texture irregularity that degrades figured fabric quality, requiring either position-sensitive let-off control or design programme modification that balances consumption rates across the warp width.
