Yarn Testing Equipment
Name：LFY-110A yarn and yarn friction coefficient tester (ply yarn method)
Details
The main purposeUsed to determine the friction characteristics between yarn and yarn.
Instrument characteristics
1. With DC motor as the constant velocity gravity source, the yarn runs at a constant speed, quiet and stable;
2. The instrument has a high-precision force measuring mechanism, which can automatically record the average force value received by the sensor and draw a curve of the force value over time on the computer in real time;
3. The friction coefficient test system can display the curve of the dynamic friction coefficient between yarn and yarn over time in real time;
4. Yarn running mechanism with imported center bearing, flexible and reliable movement and long service life;
5. Computer control, automatic data processing, test report can be printed, stored and inquired.
Technical index
1. All yarn guide wheels are located in the same plane. The upper and lower yarn guide wheels have the same diameter, and the diameter size is 20mm～50mm
2. The axis distance between the upper two guide wheels (140±5) mm
3. The axis distance between the upper and lower guide wheels (280±5) mm
4. Input tension measurement range and accuracy: 0～500CN±1%
5. Output tension measurement range and accuracy: 0～500CN±1%
6. Range of friction coefficient: 0＜u＜1
7. Yarn moving speed: (0.1～200) mm/min
8. Display content: yarn movement speed, friction coefficient
9. Power supply and power: AC220V 50Hz 300W
Applicable standards
ASTM D 3412/D 3412M-2013 Standard Test Method for Coefficient of Friction, Yarn to Yarn
