Integrating Four Point Demerit Scoring with Real Time Loom Monitor Logs
Integrating real-time loom telemetry with four-point demerit scoring automates fabric grading by mapping machine stop pulses directly to physical defect coordinates.
Demerit Point Calculation
Scoring Metric
Fabric inspection standards establish quantitative scoring protocols to penalize visual defects observed during grey cloth and finished fabric examination. Inspection teams execute a demerit point calculation by tallying slubs, thick ends, thin places, and oil stains per hundred square metres of woven linen fabric. The total penalty score determines whether a fabric lot receives first quality status or faces downgrade classification.
Quality control documentation records these numerical values directly on batch inspection tags prior to packing and export rolling.
Defect Weighting
Defect severity directly governs the point penalty assigned to each recorded flaw during fabric rolling. When operators conduct a demerit point calculation, flaws up to three inches incur one point while longer continuous defects receive up to four points per linear metre. Slubs and broken picks receive standardized point values based on visual impact and physical dimensions.
Cumulative penalty sums are normalized against total inspected yardage to yield a standardized quality score.
Acceptance Limit
Grade thresholds establish strict limits above which fabric lots face immediate rejection by export buyers. A calculated score exceeding penalty thresholds disqualifies grey cloth from high-end garment production applications. The calculation governs physical fabric defect scoring and does not measure chemical finish durability or colour fastness parameters.
