| Abstract | ||||
| Yarn tension during manufacturing has a large influence on the processing efficiency, yarn properties, and hence on fabric characteristics. In this work the dynamic yarn tension on two-for-one twister was investigated and the effect of various parameters on the dynamic yarn tension were studied. A test set-up unit was built to simulate the Two-for-one twister, so the effect of spindle speed, winding velocity and feed package dimensions on dynamic yarn tension was investigated. It was found that the yarn tension at the eye slightly changed when the spindle speed increased up to 5500 r.p.m. The yarn tension was highly affected by the increase in spindle speed above 5500 r.p.m.. It was also found that the wrap angle changed when the feed conditions in terms of feed package dimensions, spindle tension and winding velocity were changed to mentain a constant yarn tension at the eye. The increase of productivity of the Two-for-one twister causes an increase in the yarn tension at the eye. Statistical analysis was carried out to find the effect of the various parameters on yarn tension and to verify the experimental results. | ||||
