ABSTRACT:
An apparatus for making dual component fibers is provided and includes a distributor having orifices in the peripheral wall and nested within a rotary spinner. The distributor is divided into a series of generally vertically-aligned compartments by baffles positioned circumferentially around the interior of the peripheral wall, with the orifices communicating with the compartments. First and second molten thermoplastic materials are supplied to the distributor and centrifuged as alternating thin layers to the face of the spinner. The spinner is also rotated to centrifuge dual component fibers through the orifices in the peripheral wall of the spinner.
