| Abstract | ||||
| In this work the effect of weaving machine speed and stroke of heald shafts on waven warp strength was measured. The strength of sized warp threads was measured before weaving process. And the yarn strength was measured for the woven fabric for two different weaving machine speeds (650 and 850 picks/min). The raveled warp threads from the woven fabric were choosen for marked threads in the first and last heald shaft. Also some of the mechanical characteristic of warp threads was measured before and after sizing process. Theoretically the dynamic motion of heald shaft was derived for air jet weaving machine with a sinsoidal motion for heald shafts. The dynamic motion was calculated at different machine speed and different stroks of heald shafts. It was found that the machine speed and stroke of heald shafts have influence on the reduction of strength for warp threads in the woven fabric, the reduction is up to 11%. | ||||
