The Schopper abrasion tester is a precision device specifically designed to evaluate the abrasion resistance of fabrics. By simulating friction scenarios in real-world use, it quantifies the surface changes of materials under dynamic friction. It is widely used in textiles, automotive interiors, footwear materials, leather, and other fields, providing crucial data support for material research and development, quality control, and industry standard verification.

Applications

Textile Industry: Evaluating the abrasion resistance of fabrics, carpets, curtains, and other materials to optimize fabric structure and surface treatment processes.

Automotive Interiors: Testing the scratch and abrasion resistance of seat fabrics, headliner materials, and door panel trims to ensure product durability.

Footwear and Leather: Simulating the friction between shoe soles and the ground to test the abrasion resistance of footwear materials; evaluating the abrasion resistance of leather surface coatings.

Research and Teaching: Providing standardized testing methods for materials science, textile engineering, and other fields to support the research and validation of new materials.

Standards

DIN 53863-2： Textiles - Test methods - Test method for abrasion resistance of textile fabrics - Rotating abrasion test

GME 60345： Test method for determining the abrasion resistance of automotive trim materials

GMW 3283： Schopper abrasion test

VW/Audi Central Standard PV 3908： Test method for abrasion resistance of automotive interior materials (e.g., fabrics, carpets)

Features

Rotary Abrasion Mechanism: A specimen clamped on a rotating test head (166° taper angle) maintains line contact with an abrasion block, simulating tangential friction.

Modular Clamping System: Obtuse-angle cone chuck and mounting support ensure secure specimen fixation during high-speed rotation (75 revolutions/minute).

Touchscreen Interface: Real-time control panel with programmable cycles, load settings, and rotation reversal triggers.

Arc Height Adjustment: Built-in gauge for measuring sample deformation post-test, critical for assessing material resilience.

Load Customization: Interchangeable weights (50g–1500g) accommodate diverse testing requirements, from delicate fabrics to heavy-duty materials.

Space-Saving Design: Compact dimensions (325×565×560mm) and lightweight build (35kg) optimize laboratory workspace utilization.

TestProcedures

1. Sample Installation

Fix the temperature and humidity treated sample onto the rotating test head, adjusting the arch height to 5-8 mm.

2. Sandpaper Fixation

Use the pressure plate clamp to install the sandpaper onto the lower surface of the pressure plate, ensuring it is flat and wrinkle-free.

3. Parameter Setting

Input parameters such as rotation speed, number of friction cycles, and pressure value via the touchscreen.

4. Test Start

Lower the pressure plate to bring the sandpaper into contact with the sample, beginning the friction test.

5. Result Evaluation

After the test, observe the sample's mass loss and the formation of holes to quantify its abrasion resistance.
