 Full text | Abstract: In this paper, with the aim of analysis, the main nozzle was divided into four part (tubes). This allowed to analyse detailed airflow parameters of each tube, and introduce a method of experiment to test the airflow velocity in the exit nozzle and weft tension in the main nozzle. On the basis of fluid dynamics, the pull force formula of main nozzle on an air jet loom was determined in this paper. The theoretical findings agreed well with the experimental. |
