A, use:
The instrument used to determine the cotton, wool, linen, Chemical fiber and other yarns twist, twist eccentricity, strand twist.
B, the structural principle:
The instrument consists of a control box (digital display), tension mechanism, insert Creel and other components. Host untwisting direction of rotation chuck, speed, start and stop by the control box, twist count by photoelectric conversion testing is displayed by the display box control digital twist. Adjustable instrument gauge, tension applied tension during the test by a vertical lever pointer, zero self-stop use of photoelectric sensors.
