Incidence of Fiber Reversal and Change in Fiber Configuration in Rotor Spinning

Abstract

One of the most important operations in rotor spinning is the transportation of separated fibers from the feed to the rotor chamber through the transport channel. Any disturbance in the smooth flow of fibers through the channel is detrimental to yarn quality and spinning stability. In this investigation, many fibers changed their directions during passage through the channel. Straight fibers present in the feed sliver changed configurations by either getting hooked or looped. Surprisingly, long fibers changed configurations less than to short fibers.
