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.
Claims14
Apparatus for making dual component fibers comprising:
- a distributor having a distributor peripheral wall with an interior surface and an exterior surface and a distributor bottom wall, and further including orifices in said peripheral wall, said distributor being divided into a series of compartments by baffles positioned interiorly of said distributor peripheral wall with said orifices communicating with said compartments;
- equipment for supplying first and second molten thermoplastic materials to said distributor;
- said distributor including a divider for directing said first molten thermoplastic material into alternate ones of said compartments and for directing said second molten thermoplastic material into the remaining ones of said compartments;
- a spinner having a spinner peripheral wall and a spinner bottom wall, and further including orifices in said spinner peripheral wall, said distributor being nested within said spinner;
- means for rotating said distributor to centrifuge said first thermoplastic material and said second thermoplastic material through said orifices in said peripheral wall of said distributor and against the inner face of said peripheral wall of said spinner;
- and
- means for rotating said spinner to centrifuge dual component fibers through said orifices in said peripheral wall of said spinner.
