A Study of Dynamic Yarn Tension on Two-for-One Twister.(Dept.T)

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