Effect of some ring spinning and winding parameters on extra sensitive yarn imperfections

摘要

The effect of various ring spinning parameters and winding machine parameters on the yarn quality has been studied at higher sensitivity levels using the capacitance type tester. The relationship between extra sensitive imperfections and infrequent yarn faults has also been studied. It is observed that the spacer size, break draft and spindle speed of ring frame influence the imperfections and classimat faults. With the increase in twist multiplier the yarn quality improves initially and after a certain stage there is an increase in imperfections with increased twist multiplier. Within the chosen limit the effect of winding speed and tension weight of high speed autoconer on imperfections is minimal.
