Effect of Geometry on the Performance of Intermingling Nozzles

摘要

This study investigates the effect of nozzle geoemtry on the intermingling process. The domensions of intermingling nozzles with single air inlets extended across the width of a rectangualr yarn channel ar esystematiclaly varied. Nozzles with this cross-sectional shape prove to be easy to manufacture and efficient a tintermingling. The performance is evaluated by visually inspecting the intermingled yarns and by measuring the nip frequency. We have found that the performance of nozzles with large inlet widths is weakly dependent on yarn channel geometry. The performance of nozles with teh smallest air inlet widths, on the other hand, is sensitive to yarn channel geomety. The smallest and largest yarn channels we have considered give poor intermingling results.
