Effect of accelerated point distribution on sliver irregularity. Part II: optimization of draft settings in two-zone roller drafting system

Accelerated point distribution plays a dominant role in discussing sliver irregularity in drafting. This paper, which is based on a theory developed in an earlier publication, proposes a new method to optimize the draft settings using the minimum coefficient of variation (CV) of fiber accelerated point. The new approach offers advantages over the traditional regressed optimal drafted settings (to yield the least weight variation in drafted slivers) and does not need extensive laboratory trials.
