Jacquard Repeat Length Priced as Card Time and Loom Hours
Pricing Jacquard repeat length requires balancing flat card preparation fees against loom hour rate increases caused by harness mass speed penalties.
Four Point Inspection Threshold
Grading Standard
The four point inspection threshold operates within the finishing room of Chinese linen mills as the numerical boundary separating acceptable bolts from rejected yardage. Inspectors apply this quantitative limit during the final examination of woven cloth before export packing begins. Defective points accumulate according to the severity of faults observed across the surface of the textile.
Individual flaws receive penalty counts ranging from one to four based on the physical size of the irregularity found. Yards exceeding the established defect limit fail the final export quality check. Mill supervisors consult the export documentation sheet to verify that the penalty tally remains below the permitted ceiling.
Fibre grades describe the raw flax material harvested from fields prior to spinning, whereas fabric grades evaluate the structural integrity of the finished linen cloth. Internal mill standards frequently impose stricter defect penalties than the minimum criteria demanded by overseas buyers.
Scoring Mechanism
Penalty distribution relies on linear measurement rather than weight or total surface area. Inspectors measure warp breaks and filling faults along the entire length of the production run. Each detected flaw accumulates points that accumulate toward the four point inspection threshold.
Small knots receive minimal penalties because washing treatments often eliminate minor surface irregularities during finishing. Larger oil stains and heavy slubs trigger the maximum four point penalty due to the impossibility of correction downstream. Meters of fabric containing excessive flaws immediately trigger rejection flags on the inspection ticket.
Mill operators adjust spinning machinery parameters when defect frequencies rise above acceptable limits. Corrective adjustments reduce subsequent yarn irregularity before the weaving stage begins.
Export Tolerance
Overseas purchasers establish contractual limits that govern the final acceptance of linen consignments leaving the factory floor. Shipments failing the four point inspection threshold undergo secondary processing or return to the weaving department for repair. Commercial penalties apply when defect frequencies approach the agreed rejection limit without exceeding it.
Importers utilize these defect scores to negotiate price adjustments on lower quality lots. Finished linen intended for luxury tailoring demands stricter enforcement than utility grade sheeting. Export documentation records the final score to protect both parties against transit disputes.
Commercial agreements determine whether rejected bolts undergo discounting or complete destruction at the mill site.
