Defect Mapping and Loom-Level Quality Diagnosis
topic
Fabric defect mapping records the warp position, pick number, and defect type for all fabric defects observed during weaving and fabric inspection, with positional analysis identifying defects repeating at fixed warp intervals indicating reed or heddle mechanical problems, defects at fixed pick intervals indicating loom mechanism faults, and random distribution suggesting yarn quality variation as the primary cause, enabling targeted maintenance and quality intervention guided by defect pattern analysis.
Role
Provides the diagnostic intelligence for distinguishing between preparation-related and loom-related fabric defect causes from the spatial pattern of defect distribution in the fabric, enabling efficient maintenance resource allocation by identifying whether defect reduction investment should target warping and sizing process improvement or loom mechanism maintenance, with defect mapping being the bridge between fabric quality outcomes and the upstream process causes whose correction will eliminate the observed defect patterns.
