ABSTRACT:
This is a process and apparatus for the preparation of fasciated spun yarns, which includes feeding separate single fibers formed by opening and drafting a continuous staple fiber bundle into a rotor (20), collecting and holding the single fibers on a fiber-collecting portion of the rotor (20) and taking out the collected fibers through a center piece (26) by delivery rollers (33) while strongly false-twisting the collected fibers in the same direction as that of true twists given by the rotor (20) into a twisted yarn by a false-twisting apparatus arranged between the rotor (20) and the delivery rollers (33), wherein the separated single fibers are supplied to a travelling plane for the twisted yarn between the fiber-collecting portion of the rotor (20) and the center piece (26) to entangle some of the single fibers with the twisted yarn in the strongly false-twisted state, and the entangled single fibers are entwined around the periphery of the twisted yarn by subsequent release of the false twists of the twisted yarn.
