Apparatus for making dual-component fibers is provided and includes a spinner having a peripheral wall. The spinner includes orifices located on the peripheral wall thereof for centrifuging the dual-component fibers, with the spinner being divided into a series of generally vertically aligned compartments by baffles positioned circumferentially around the interior of the peripheral wall. First and second molten thermoplastic materials are supplied to the spinner and directed into alternate ones of the compartments so that adjacent compartments contain different thermoplastic materials. Passages are located in each of the compartments through which the respective molten thermoplastic materials flow to the orifices on the peripheral wall of the spinner. The passages in adjacent ones of the compartments communicate with one another and with the orifices to joint the first and second molten thermoplastic materials together into dual-component fibers. |
