Comparing the abrasion resistance of different fabric structures to guide product improvement.

3. Materials Research and Development

Providing abrasion resistance data support for new fiber materials and coating processes.

Comparing the impact of different treatment processes (such as waterproofing and fire resistance) on abrasion resistance.

4. Third-Party Testing

Serving as a third-party testing device to verify whether materials meet international standards (such as ASTM D4157. BS EN ISO 12402-7. FTMS 191A 5304. etc.).

5. Electronics Industry

Verifying the friction resistance lifespan of mobile screen protectors, touch panels, and keyboard coatings.

6. Packaging Industry

Testing the abrasion resistance of labels and packaging films to prevent information blurring, coating peeling, or damage due to friction during transportation or storage.

Accessoriess

Standard accessories:Abrasion media (e.g., standard abrasive paper/cloth), sample fixing clamps, standard weights, digital counter, power cord, user manual, certificate of conformity, and calibration tools (for some models).

Optional accessories: Additional abrasion media, specialized abrasive heads, temperature/humidity control modules, pre-tension adjustment fixtures, and result evaluation auxiliary tools (e.g., light boxes).

Test Procedures

1. Sample Preparation

Cut test specimens according to the standard (commonly 120mm×20mm, 140mm×50mm, etc.), and condition them for 24 hours (23±2℃, 50±5% RH). Elastic leather samples should be stretched by 10% (or to the maximum stable elongation).

2. Equipment and Medium Pre-treatment

Clean the platform and calibrate the pressure (500g for dry friction / 1000g for wet friction); for wet friction, treat the wool felt/cotton cloth with boiling water and squeeze out excess water until it weighs approximately 1g (or has a water absorption rate of 100±5%).

3. Parameter Setting and Testing

Select dry/wet mode, set the number of friction cycles (5-500 cycles, e.g., ISO 11640 specifies 50 cycles for dry rubbing and 10 cycles for wet rubbing), and speed (30-60 cycles/minute); fix the sample and friction medium, and start the instrument until the preset number of cycles is reached.

4. Result Evaluation

Under D65 light source, use a gray scale to evaluate the staining grade of the friction medium (grades 1-5) and the discoloration grade of the leather. Record whether there is pilling/cracking on the surface. Take the lower value from parallel tests.
