ABSTRACT

The end breakage rate rises steeply with increasing spinning tension and its variation. In this respect, the peak value of spinning tension is more important than the average value and for a better performance of ring frame; the peak value of spinning tension should be lower. Because when the peak tension exceeds the strength of weak places in the yarn, it leads to end break. In addition, a very high spinning tension results the deterioration of yarn quality parameters, such as elongation-at-break, unevenness and imperfections. Hence is becomes necessary to measure and control spinning tension at an optimum level throughout the cop build.
