Dynamic Yarn-Tension Detection Using Machine Vision Combined with a Tension Observer
Machine vision can prevent additional stress on yarn caused by contact measurement, as well as the risk of hairiness and breakage. However, the speed of the machine vision system is limited by image processing, and the tension detection method based on ...

Analysis of yarn tension forces in the weft knitting phase of circular knitting machines [PDF]
In the process of loop formation, the weft knitting phase has a dominant place, both from the aspect of forming the loop as well as determination its length and geometric shape. The loop length is the most important technological parameter in the knitted

Sensitivity Optimization of Surface Acoustic Wave Yarn Tension Sensor Based on Elastic Beam Theory
The measurement of yarn tension has a direct impact on the product quality and production efficiency in the textile manufacturing process, and the surface acoustic wave (SAW) yarn tension sensor is a good option for detecting the yarn tension.

Yarn Tension in Winding Mechanism.
Variations in stress in a yarn beam produced by the yarns wound on it were examined and recorded during winding. The yarns used were nylon filament and cotton yarn. The stress in the beam core in axial and circumferential directions was examined with wire strain-gauges attached inside the beam core.Data on the following subjects have been obtained from

Yarn tension model and vibration analysis during unwinding of carbon fiber bobbins
A low-quality unwinding process of the unwinding machine can lead to downtime of the knitting machine and loss of fabric quality. To address this issue, we studied the tension and vibration of carbon fiber yarns during unwinding.
