Schopper Abrasion Tester

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.

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.

Parameters

Accessoriess

Standard accessories：motor, conical chuck, sandpaper, tray, and weights.

Test Procedures

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.

FAQ

1. What is the primary difference between the Schopper test and other abrasion tests like Martindale?

The Schopper test utilizes a rotary motion with a specific conical mounting head (166° taper), creating tangential friction. Unlike the Martindale's Lissajous pattern, the Schopper method is often preferred for specific automotive standards (GMW, VW) to evaluate how materials react to directional and circular abrasive forces.

2. What does this product do?

It helps determine a material's wear life under prolonged friction, color adhesion, and surface integrity, providing quantifiable abrasion resistance metrics.

3. How does it work?

The sample rotates on a turntable, driving two pressurized abrasion wheels. Since the contact axes of the wheels and sample are misaligned, combined vertical and radial friction creates a circular wear band.

4. Why is this product important?

It is crucial for ensuring product durability. By quantifying the abrasion level of fabrics or coatings, it helps prevent quality complaints and return risks caused by premature surface wear.

5. Which industries is this product suitable for?

It is widely applicable in automotive interiors, textiles and leather, plastic packaging, paint coatings, wood flooring, and electronic communications industries.
