Attribute Control Charts for Textile Defect Monitoring
topic
p-charts monitor fraction defective in fabric inspection samples of variable size, np-charts track defective item count in fixed size samples, c-charts control defect count per fixed inspection unit, and u-charts monitor defects per variable unit area, all applied to fabric visual inspection, seam quality audit, and print registration deviation monitoring in textile production.
Role
Extends statistical process control to count and classification data generated by fabric inspection, seam quality audit, and appearance grading operations where individual measurements are replaced by defect counts and pass-fail classifications, enabling statistically based process monitoring of intrinsically non-continuous quality characteristics.
