Abstract
An apparatus for making dual component fibers is provided and includes a spinner having peripheral and bottom walls. 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. A first divider is provided in the spinner for directing the first molten thermoplastic material into alternate ones of the compartments, and a second divider is provided for directing the second molten thermoplastic material into the remaining 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.
