<p>Apparatus for making dual-component fibers (68) includes a spinner (60) having a peripheral wall (64) with orifices (90) for centrifuging the thermoplastic materials (A,B) constituting the dual-component fibers. The interior of the spinner (60) is divided into a plurality of compartments (88) by baffles (86) positioned circumferentially around the peripheral wall, the baffles being inclined at an angle of about 5 DEG to about 75 DEG from the vertical rotational axis (66) of the spinner, and most preferably at about 450 from the vertical; and by a divider (82) which directs the thermoplastic materials (A,B) into alternate compartments (88) so that adjacent compartments contain different thermoplastic materials. The orifices (90) are aligned with the baffles (86) but are wider than the thickness of the baffles so as to communicate with adjacent compartments and so that the thermoplastic materials are centrifuged as dual-component fibers (68). <IMAGE></p> |
