Standard Operating Inspection Protocol for Four Point Greige Scoring
ASTM D5430 four-point scoring normalises greige defects per 100 square yards, capping penalties at four points per yard to decide lot acceptance.
Linen Weave
Interlacing Geometry
Orthogonal interlacing of longitudinal warp and transverse weft strands forms a stable textile structure based on one-over, one-under sequences. Termed plain construction across the broader textile sector, the specific linen weave designates this symmetrical configuration executed with natural bast flax yarns. Each warp strand alternately passes over and beneath successive weft picks, producing a balanced surface with maximum interlacing frequency per unit area.
Structural cohesion produces low yarn slippage and firm hand feel in finished cloth. The classification excludes diagonal twill structures, float-heavy satins and complex jacquard patterns.
Loom Execution
Production parameters on industrial rapier looms must accommodate the low elasticity of wet-spun flax yarns. Shed timing and harness leveling require precise adjustment to prevent yarn snap during heddle changes, because flax fibres possess minimal elongation before rupture. Applying a balanced linen weave distributes abrasive loom friction evenly across all active harness frames, minimizing warp breakage rates per hundred thousand picks.
Mill loom logs record warp breaks, weft insertions per minute and shed tension metrics to balance output speed against fabric regularity. Uniform yarn counts in warp and weft yields create square cloths suitable for luxury apparel, whereas unequal counts generate distinctive slubbed drapery textiles.
Structural Standard
Buyer contracts define exact yarn densities per centimetre alongside fabric weights in grams per square metre. Fabric certified as a compliant linen weave delivers superior air permeability and laundering durability over loose decorative structures.
