Standard Cantilever Testing and Defect Scoring in Greige Cloth Inspection
Standard cantilever testing and four-point inspection verify greige cloth stiffness and fault densities to enforce contract specifications before finishing.
Warp Float
Defect Origin
Surface examination of grey linen cloth during loom shedding exposes warp float irregularities where lengthwise yarns bypass multiple transverse picks incorrectly. Chinese mill standards categorize this structural deviation as a loom timing error during the weaving stage rather than a spinning fault originating from flax preparation. Inspectors record the resulting surface anomaly on the primary production docket before finishing operations commence because subsequent bleaching or dyeing procedures permanently lock displaced yarns into the fabric matrix.
Grading Tolerances
Buyer acceptance criteria permit specific density limits for localized surface irregularities on commercial flax textiles. Domestic mill protocols allow three minor yarn skips per square meter on unbleached sheeting destined for export, whereas foreign garment manufacturers enforce stricter zero tolerance thresholds on high density handkerchief weights. Laboratory technicians measure linear deviation using standardized counting glasses against the official export specification document.
Remedial Processing
Corrective action requires manual intervention by loom technicians who reset the shedding harness timing mechanism before subsequent batches enter the wet finishing department. Operators adjust heddle shaft lifting sequences to restore proper interlacing frequency between warp ends and filling picks. Prevention of recurring surface defects depends entirely upon maintaining consistent tension across the entire beam assembly throughout the weaving cycle.
