Greige Fabric Defect Inspection Standards across Sectional Warping Batch Runs
Sectional warping batch inspection requires matching drum cone angles to yarn build and scoring periodic band faults under strict four point penalty thresholds.
Lease Reed
Separation Specification
The count of warp ends passing through a single dent in a weaving reed determines the density and structural integrity of grey linen cloth. This lease reed setting establishes the physical spacing between individual yarns to prevent friction and breakage during the shedding process. Precise control over these intervals allows manufacturers to regulate the weight of the finished fabric and ensures that the tension remains uniform across the width of the loom.
Calibration Metric
Each adjustment of the reed position alters the geometric gap through which the warp yarn travels during high-speed operation. Mills calculate the required density by dividing the total number of warp ends by the available width of the reed frame. Variations in this configuration affect the hand and the drape of the resulting material.
Incorrect spacing generates uneven tension profiles that cause streaks in the final product.
Production Boundary
Maintenance of this standard relies upon the alignment of the dent walls relative to the shuttle or rapier path. Technicians measure the deviation between the planned density and the actual spacing to confirm that the equipment maintains the specified weave structure throughout the production run. Consistent application of this arrangement limits defects in the finished linen by maintaining the integrity of the individual fibre bundles as they intersect with the weft.
