LFY-209 Silk Smoothness Tester

Main application
It is used for measuring the friction performance on the surface of silk fabrics. It is an essential testing instrument for enterprises, research institutions, foreign trade inspection departments, etc. to inspect the quality of silk fabrics.
Instrument features
It adopts the friction angle method - inclined plane sliding method to test the friction coefficient. The method is simple and can directly test the static friction coefficient or calculate to test the dynamic friction coefficient. Technical indicators
1. Dynamic and static friction coefficient test range: 0 - 1
2. Rotational angular velocity of the test plate: 1.5°/s
3. Mass of the friction head: 156g
4. Base area of the friction head: 25mm × 25mm, pressure is 2.45kPa when in horizontal state
5. Diameter of the fingerprint wire: Φ0.5mm
6. Effective size of the sample: 105mm × 35mm
7. Pre-tension of the sample: (along the test direction) 68.6cN, which is 19.6cN/cm
8. Angle resolution: 0.5°
