The Potential of False Twist to Assist in Handling Low Strength Cotton Slivers

Abstract

In a preliminary investigation aimed at improving the processing of lightweight slivers (<3 ktex), the effect of low levels of twist on sliver strength is quantified. This is followed by trials to determine whether a passive false-twist unit (spiral) can be used to impart temporary strength to assist the transfer of sliver from a supply can to the next processing machine. The generated level of false twist is studied, and the spiral is subsequently used on a roving frame to process different sliver weights at various drafts. The experiments show that false-twist can offer a potential technique for dealing with low strength and lightweight cotton slivers. From the results, it appears that such a device has little effect on drafting regularity.
