Construction Density
Primary weave specifications define the spatial frequency of warp and weft yarns per unit length in unfinished fabric taken directly from the loom. A fabric greige sett states the exact number of warp ends and filling picks per inch or centimeter prior to washing, desizing or finishing treatments. Loom technicians verify density using counting glasses or digital pick counters under uniform fabric tension.
Baseline measurement determines downstream finish contraction, cover factor and total grey fabric mass.
Reed Geometry
Reed width and reed count establish warp end spacing across the loom bed, while take-up roll speed controls filling insertion density. High pick densities reduce weaving speed and elevate reed abrasion on delicate warp yarns.
Fabric Compactness
Weaving managers calculate cover factor from raw yarn diameters and warp-weft spacing to evaluate structural tightness. Tight constructions resist yarn displacement during handling but require elevated warp tension during weaving. Adjusting the take-up motion gear ratio corrects pick density drift before off-spec fabric rolls accumulate at the loom batcher.
Unfinished Boundary
Unfinished density figures do not reflect final finished fabric dimensions due to wet processing contraction and stenter frame tentering. Elasticized yarn constructions undergo immediate off-loom contraction, requiring off-loom relaxation before accurate count measurements occur.
