Abstract
This study is focused on the optimization of drafting process through measuring drafting force and short term irregularities of fiber strand. Drafting force is the instinctive factor initiated by the frictional forces between slow moving and fast moving fibers during attenuation. Drafting force can be a good source of information regarding dynamic fiber behavior and reflects combined effect of multiple fiber and process parameters, for a particular materiel. The interaction between break draft and drafting force and how these in turn affect the irregularity of sliver has been analyzed by utilizing data from online drafting force device. The results showed that dynamic drafting force increases with the increase in break draft around 1.4 and then decreases with further increase in break draft. Short term sliver irregularity decreases up to 1.4 break draft and then increases as break draft increases. Furthermore, the region where drafting force reaches its maximum corresponds to the minimum sliver unevenness. Optimum break draft setting can be achieved at a point where the drafting force reached its maximum along with minimum short term sliver irregularity.
