The drafting tenacity of jute slivers of different qualities and its dependence on sliver weight and sliver crimp have been estimated. The drafting force required for white variety is more than that for the tossa variety. Drafting force has a linear regression with sliver weight and crimp. Drafting force variation has been correlated with sliver irregularity as well as with irregularity of the resultant yam. The effect of different amounts of batching oil and cationic softeners on the drafting tenacity of the sliver has also been studied. The drafting tenacity increases with increase in the amount of oil up to 2.2% and decreases thereafter.</span>
