    摘要: A method for fiberizing organic material includes rotating a spinner having a bottom wall and a peripheral wall that extends upwardly from the bottom wall and terminates in an upper end, wherein the spinner has a cavity defined by the bottom wall, the peripheral wall and a plane extending through the upper end of the peripheral wall generally parallel to the bottom wall. The method further includes creating turbulence within the spinner cavity, supplying molten organic material to a delivery tube wherein the delivery tube terminates at a point located outside of the spinner cavity, discharging molten organic material from the delivery tube with enough momentum to overcome the turbulence and reach a predetermined location in the spinner cavity, and centrifuging fibers from the molten organic material.

    摘要: In a method for producing hollow polymer fibers, molten polymer is supplied to a rotating polymer spinner having a peripheral wall. The spinner rotates so that molten polymer is centrifuged through a first tube extending through the peripheral wall of the spinner to form fibers. Gas is introduced into the interior of the molten polymer to form hollow polymer fibers. The hollow polymer fibers are then collected as a product such as a mat. The hollow polymer fibers produced by the method are microfibers having an average outside diameter of from about 2.5 microns to about 62.5 microns.
