ABSTRACT:
A process for manufacturing reinforced false twist yarns includes employing braking rolls, drawing bands, pulling rollers, twisting rolls, and yarn guides to manufacture a reinforced false twist yarn from first and second fiber rovings and from a continuous fiber yarn. The yarn guides are separated from one another such that, when the first roving is combined with the second roving and continuous fiber yarn, untwisted regions of the first fiber roving are in substantially non-overlapping relationship with untwisted regions of the second fiber roving.
