Abstract: A simulation model has been suggested for a single nozzle air-jet loom to analyse weft yarn motion under different conditions of weaving procedure. For this purpose, weft yarn motion equation has been derived using this model, physical laws and combination of air velocity and air-yarn friction coefficient equations. This analytical model for drum storage system is developed to investigate the weft yarn behaviour during weft insertion, i.e. displacement, velocity, and yarn tension. Numerical solutions of yarn motion equations have been obtained. Tension analysis of weft insertion has been carried out both theoretically and experimentally using different cotton-polyester yarn counts under different air pressures. The results show good agreement between theoretical and experimental values of weft yarn tension.
