| Abstract | ||||
| In the present work, the behaviour of dynamical weft tension during unwinding from shuttle have been studied. The phenomenon has been investigated considering the effect of yarn parameters, such as yarn count and hairness, traverse length of weft bobbin, unwinding speed from the shuttle and shuttle tension. The experiments were carried out by varying all factors at two different levels using 25 factorial design technique. The unwinding tension corresponding to the tip and base of weft bobbin as well as the differences between the two position tension curves (A-Q), is recorded and statistically evaluated. The results indicated that the weft tension variation was found to be affected significantly by: weft yarn count, unwinding speed and shuttle tension. In terms of two and three factor interactions, the results show : weft count with shuttle tension (x3 x5), as well as count with unwinding speed, and shuttle tension (x3 x4 x5) affect significantly on the weft tension variation. | ||||
