Structural Ratio
The physical distortion metric known as warp crimp percentage quantifies the displacement distance of longitudinal yarn paths as intersecting elements cross under and over transverse picks inside flax sheeting production. Hangzhou quality laboratories calculate this linear contraction value during the preliminary testing stage before the greige fabric leaves the loom shed for chemical treatment. Factory technicians enter the resulting proportion into the production ledger alongside tensile strength ratings and surface mass densities.
Acceptance Tolerance
Mill floor inspectors contrast the measured loom state deviation against buyer specification sheets during export clearance evaluations. Exceeding contracted dimensional limits triggers rejection at the warehouse dock because excessive yarn displacement distorts the final garment silhouette after laundering. Strict contractual boundaries separate internal mill standards from foreign client thresholds, since domestic manufacturing tolerances often permit wider latitude for natural fibre irregularity than offshore retail houses accept.
Finishing Impact
Thermal shrinkage during wet finishing alters the original linear displacement ratio established during loom shedding. Operators adjust tension rollers inside continuous scouring ranges to control residual yarn displacement before final rolling and packaging. Precise mechanical management of longitudinal wave magnitude prevents skewing defects in exported linen garments.
