Calculating Vessel Payload Capacity from Master Greige Roll Weights
Calculate vessel payload capacity by adjusting greige roll weights for sizing loss, finish pick-up, moisture regain, and core tare volume constraints.
Weft Tension Width
Fabric Dimension
Dimensional stability of a textile product depends upon the force applied to the filling yarns during processing. The weft tension width quantifies the specific lateral contraction occurring when yarn delivery rates fluctuate during the shuttle or rapier insertion phase. This measurement determines the actual finished breadth of a textile before it undergoes final heat setting or chemical stabilization.
Mechanical Constraint
Tension variations across the insertion path alter the crimp distribution within the weave structure. If the force exceeds the elasticity of the yarn, the fabric narrows beyond the intended technical specification. Operators adjust the intake rollers or the air jet nozzle pressure to maintain a target measurement during high speed production.
Production Variance
Variations in the moisture content of the fibre stock change the way the yarn responds to these lateral forces. Natural fibres shrink or expand when humidity levels shift, creating inconsistent edge profiles that complicate later cutting stages in garment manufacturing. Factories record these shifts to predict the shrinkage potential during subsequent washing or dry finishing cycles.
Quality Benchmark
Precise control of this geometry ensures the selvage remains parallel to the warp direction throughout the entire roll length. Deviations indicate uneven mechanical pull that results in skewed grain or spirality in the final sewn garment. A consistent measurement represents the most reliable predictor of uniform fabric behavior under uniform conditions.
