Abstract
Apparatus and method for producing organic fibers by means of a centrifugal spinning process. The fiberizing disc and the molten material introduction nozzle are designed to prevent the molten material from escaping the disc prior to being fiberized. The heater for heating the material in the disc is designed to accommodate the lower melt temperature of the material to be fiberized. Also, means are provided for diverting the flow of fibers from the disc to cause the fibers to be more precisely or uniformly deposited. The fibers are substantially immediately cooled upon exiting the fiberizing disc, resulting in a fiber structure that is at least about 60% amorphous.
