spinning tension in the yarn is the tension that finally penetrates almost to the
spinning triangle and which is responsible for the greater part of end breaks
in practice. For a given count of yarn, the tension is strongly dependent on the
traveler speed and the balloon height.

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 optimum level through out the cop build.
