Warp Tension Uniformity Across Width
topic
Warp tension uniformity across the fabric width requires equal tension in all ends from selvedge to centre, measured by sampling tension at multiple positions across the warp width using a tensometer, with non-uniformity arising from uneven beam winding hardness, damaged or worn heddle eyes creating localised friction, reed damage creating tension anomalies, or uneven warp yarn count causing tension variation from the inverse relationship between yarn cross-sectional area and extension at given load.
Role
Ensures that all warp ends experience equivalent tension conditions during weaving, with tension non-uniformity across the warp width causing position-specific elevated break rates that appear as systematic patterns in warp break location data, indicating preparation or loom mechanical problems at specific width positions that systematic across-width tension measurement can identify and localise for targeted correction.
