The Influence of Machine Parameters on the Properties of Double Jersey Knitted Fabrics

The present work is an experimental account of the way in which several machine settings, particularly cylinder knock-over and dial-height, influence fabric dimensions, course length, bending behavior and load extension of fabrics produced on a circular knitting machine. The results show that there are certain optimum settings for such variables as knock-over depth and dial-height for producing fabrics with optimum liveliness, dimensions and bending behavior. This study confirms the suggestion that due to the asymmetry of fabric take-down on circular double jersey machines, it is not possible to produce a fabric with identical properties on the face and back sides. No conclusive evidence of robbing yam from the cylinder loops to dial loops which cause asymmetry in the fabrics could be found but alternate suggestions were examined.
