Force and Tension Measurement in Yarn Transport
topic
Yarn tension monitoring along the yarn path from package supply through processing to wind-up uses pigtail tensiometers, electronic tension transducers, and non-contact capacitance sensors measuring yarn tension from 0.5 to 500 centiNewtons with response frequencies of 100 to 1000 hertz, providing the real-time tension data for process control systems that maintain tension within the processing window for each yarn count and machine speed combination.
Role
Monitors the yarn tension that governs stitch length in knitting, warp sag in weaving, and drawing uniformity in false-twist texturing, providing the measurement feedback for closed-loop tension control systems that maintain tension within specification despite yarn package diameter decrease, speed variation, and machine vibration that would cause tension variation affecting fabric quality without active tension control.
