| Friction Head Load | 9 N (standard; adjustable 5–15 N for custom tests) |
| Stroke Length | 100 mm (adjustable) |
| Friction Speed | 60 ± 2 cycles/min (1 cycle = 1 double stroke) |
| Sample Dimensions | 140 × 50 mm (standard leather/textile swatches) |
| Abrading Fabric | Standardized cotton cloth (e.g., Crockmeter cloth per ISO 105-F10) |
| Power Supply | 220V/50Hz, 60W |
| Dimensions | 500 × 350 × 300 mm (L × W × H) |
Working Principle
- Sample Mounting: Leather or fabric specimens are clamped into 4 individual stations.
- Friction Head Application: A weighted abrading cloth (9 N load) moves back and forth across the sample surface.
- Cycle Execution: The machine completes 50–100 cycles (customizable) to simulate wear.
- Color Assessment: Post-test, the abrading cloth is evaluated for dye transfer using a gray scale (AATCC EP1, ISO 105-A03) or spectrophotometer.
Test Principle & Applications
- Color Fastness Evaluation (ISO 11640/AATCC 8):
- The abrading cloth is rated on a 1–5 gray scale (1 = severe staining, 5 = no transfer).
- Pass/fail criteria depend on industry standards (e.g., ≥4 for automotive upholstery).
- Key Industries:
- Leather Goods: Validating color retention in handbags, shoes, and furniture.
- Automotive: Testing seat covers, steering wheels, and interior trims.
- Apparel: Assessing dye stability in jackets, gloves, and accessories.
