| Abstract | ||||
| In the present work, the mutual effect of air pressure at nozzles and position of back nozzle with respect to main nozzle on initial air drag, final air drag and yarn insertion time is analysed. This simulate a multi color air jet insertion system. Factorial design technique using Box and Hunter method is applied. The analysis shows that the air pressure and the position of the back nozzle in terms of its distance from the main nozzle and the angle between the nozzles axes have a significant effect on air drag and yarn insertion. This helps in selecting a suitable position of the back nozzle to get a small yarn insertion time is at a considerable air pressure. | ||||
