  • Hollow polymer fibers using rotary process
    Patent number: 5622671
    Abstract: 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.

  • Method and apparatus for drying sized glass fibers
    Patent number: 5620752
    Abstract: A method and apparatus is disclosed for producing dried sized glass fibers wherein a drying device is used to produce current flow along sized fibers to thereby partially or fully dry the size on the fibers. The apparatus may include an applicator for applying a size to the fibers and a drying device which comprises a high voltage electrode connected to a high voltage source and at least one grounded electrode. Drying is performed by passing the sized fibers by the electrodes such that a current flows along the sized fibers from the high voltage electrode to the at least one grounded electrode. The grounded electrodes may comprise grounded gathering shoes.
