LFY-109F Dry-Wet State Yarn and Yarn Abrasion Resistance Testing Instrument

Main purpose

The instrument is used to test the self-maintaining wear resistance of yarn and various rope lines in both dry and wet conditions. 
Technical Characteristics 
The instrument is a test device for evaluating the self-maintenance performance of yarn and various rope lines in both dry and wet conditions. It is controlled by a computer for testing and data processing. Through the test, it can display the average number of wear-resistant times of the yarn, the coefficient of variation of wear-resistant times, the maximum value, and the minimum value, etc. 
Technical indicators 
Friction stroke: (50 ± 4) mm; 
2. Friction speed: 60 to 70 times per minute; 
3. Friction angle at the vertex: 34°; 
4. Center distance between the upper and lower guide wheels: (254 ± 2) mm 
5. Data output items: Average friction times, coefficient of variation of friction times, confidence intervals; 
6. Test results: Can be stored and queried; 
7. Pre-tension: 5g, 10g, 15g, 20g, 25g, 30g, 35g; 
8. Working power supply: AC 220v; 50Hz.
