Abstract
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 compartments by baffles positioned circumferentially around the interior of the peripheral wall. The baffles are positioned at an angle of from about 5.degree. to about 75.degree. from vertical, and most preferably about 45.degree. from vertical. The number of orifices on the spinner peripheral wall can thus be increased to increase the throughput of fibers from the spinner while still maintaining a minimum required spacing between orifices for the structural integrity of the spinner.
