Audit Procedures for Fibre Reconciliation across Jiangsu Linen Weaving Mills
Audit Jiangsu linen mills by reconciling dry-conditioned raw fibre intake against desized fabric output and verified scrap ledgers.
Air-Jet Weaving Yield
Efficiency Baseline
The proportion of active insertion time during which a high-speed loom operates without yarn breakages determines the overall efficiency of fabric production. Known as the air-jet weaving yield, this industrial percentage measures the output of finished linen cloth against the theoretical maximum of the machine. It tracks the operational performance of weft insertion using compressed air.
Because flax yarns possess natural irregularities and low elasticity, they are prone to snapping under high pneumatical tension. Low values for this metric indicate that yarn preparation or sizing is inadequate for the high speeds of modern air-jet looms.
Operational Tracking
Automatic sensors record each stoppage caused by warp or weft breakage during the weaving shift. These events are logged by the control system of the machine. The raw data are then converted into an efficiency percentage.
Defect Prevention
High yield rates correspond directly to lower production costs and fewer fabric defects, as every machine stoppage creates a potential start-up mark in the linen. Mill managers use these figures to evaluate the quality of incoming flax yarn lots. When yarn quality fluctuates, the weaving yield shifts immediately, triggering changes in the sizing formulation or loom speed to protect the woven fabric from structural faults.
