Testing and analysing on weft kinematics parameters of Donier air-jet loom

In order to analyze the weft kinematics parameters such as the displacement,flight velocity and acceleration during the whole process of weft insertion on air-jet loom,the weft insertion motion state of Donier AWV8 /S air-jet loom was taken by a high-speed video camera.By analysing the data,it can be seen that the weft velocity of Donier AWV8 /S air-jet loom can be divided into four stages sequently i.e.rapid acceleration,smooth acceleration,smooth deceleration,and rapid deceleration.It has a reasonable motion state distribution,and the impact on the weft yarn is small during the whole process of weft insertion.It is beneficial for high-speed weaving wide-width fabrics,lessening loom stoppage,and enhancement of efficiency.
