Effects of air and yarn characteristics in air-jet filling insertion Part II: Yarn velocity measurements with a profiled reed

In Part I of this series, air pressure and air velocity are measured on an air-jet filling insertion simulator with tube and profiled reed. In this second part, the filling yam insertion time is measured on the air-jet filling insertion simulator with the profiled reed, and yam velocity is calculated. The effects of supply pressure and running speed on filling insertion are analyzed, as are the effects of yarn hairiness, twist, ply, yam count, and yarn manufacturing system on insertion time. The results show that most of the yarn properties have an effect on yarn insertion behavior.
