Comprehensive Defect Classification System
Our technical teams categorize defects into critical/major/minor classifications:
Sewing Defects (Critical)
- Stitch density variance >±2 SPI from specification
- Seam puckering exceeding 3mm depth
- Thread tension inconsistency >15%
Color Consistency (Major)
- ΔE >1.0 under D65 illumination
- Metamerism failure under multiple light sources
- Shade band deviation beyond approved limits
Dimensional Accuracy (Major)
- >±0.5cm variance from tech pack specifications
- Pattern mismatch >2mm at seam intersections
Finishing Defects (Minor/Critical)
- Button attachment strength <70N (ASTM D5171)
- Zipper cycle failure before 5,000 operations
- Untrimmed threads >3mm length
Advanced Quality Control Methodology
Ludyway employs integrated QC systems:
| Method | Technology | Precision |
|---|---|---|
| Raw Material Testing | Martindale abrasion testers, GSM scales | ±0.5% measurement accuracy |
