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