ABSTRACT:
A substantially twist-free, crimped, continuous, multifilament yarn containing randomly-spaced, tightly entangled nubs and the process and apparatus used for making such yarns is disclosed. The nub yarn is made by feeding a substantially entanglement-free multifilament crimped continuous yarn through a forwarding jet, through an aspirating entanglement jet where nubs are formed and passing the yarn through a loop guide. The nubs of the yarn are less than one inch in length and the yarn is useful in textile and carpet end uses.
