Parameter Specification

Number of Stations 4 (simultaneous testing of 4 samples)

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.
