Four-Point Inspection

Assessment Mechanism

Inspectors deploy a specific methodology to calculate the score assigned to each textile unit. A defect measuring three inches or less earns one point, while faults between three and six inches receive two points. Flaws ranging from six to nine inches attract three points, and anything exceeding nine inches carries a four-point penalty.

The calculation requires the inspector to divide the total points accumulated by the actual number of square yards inspected to reach a final density score. If the density exceeds the predefined limit, the roll fails inspection. This procedure remains consistent across global mills to maintain parity between suppliers.

Manufacturers track these metrics to pinpoint recurring issues within specific looms or finishing cycles. Proper documentation allows the facility to identify whether equipment calibration or yarn sourcing causes the observed irregularities.

Production Verification

Quality controllers examine material under high-intensity lighting as the fabric moves across a backlit inspection table at a controlled speed. Technicians mark individual blemishes with adhesive strips to ensure visibility during the logging phase. When the audit occurs at the final stage of manufacturing, personnel confirm that the physical properties of the fibre match the original specification sheet.

Operators measure the width of the fabric at regular intervals to detect bowing or skewing issues that occur during the heat setting phase. Disagreements arise between mills and brands regarding the maximum allowable penalty count for complex high-end textiles versus basic commodity fabrics. Some buyers mandate stricter thresholds for continuous prints where a single flaw ruins the entire garment layout.

Consistent application of this logic reduces waste during the cutting process by identifying rolls that prevent efficient fabric usage.

Quality Threshold

The classification system mandates that the defect count remains below the specific density limit established in the purchase agreement. Fabric rolls failing this check undergo corrective actions such as spot repair or removal of the damaged segment. Buyers reserve the right to return entire shipments when the statistical average falls below the contractual grade.

High penalty scores indicate failure in the quality control chain starting at the spinning frame. Maintenance schedules for weaving machines depend on the frequency of these recorded errors. Precise recording of defects ensures that manufacturers remain accountable for the consistency of their output.

This system provides an objective measure of fabric integrity that governs the commercial relationship between textile mills and apparel producers.
