YARN FRICTION TESTER
This machine determines the friction coefficient of yarns during the friction to metal surface.
This machine calculates the frictiction coefficient of yarns by friction angle of 360°. The speed of the machine is between 0-200 m/min. The pre-tension is adjusted by pretensioner. Yarn delivery is provided by bobbin creel. And this machine has a waxing unit.
Pretension can see on the screen. And, pretension value can calculate on the PLC screen
