The Potential of False Twist to Assist in Handling Low Strength Cotton SliversCollege of Textiles, North Carolina State University, Raleigh, North Carolina 27695, U.S.A.
College of Textiles, North Carolina State University, Raleigh, North Carolina 27695, U.S.A. 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.
