<p>A new fiber-forming method, related apparatus, and new fibers prepared by the method are taught. In the method extruded filaments of fiber-forming material are directed through a processing chamber that is defined by two parallel walls, at least one of which is instantaneously movable toward and away from the other wall; preferably both walls are instantaneously movable toward and away from one another. Movement means provide instantaneous movement to the at least one movable wall. New fibers collected as a product of the process can include fiber randomly interrupted by isolated fiber segments, the isolated fiber segments constituting a minor amount of the fiber and forming the terminus of an unaffected main portion of the fiber, being of a fiber form, and having a larger diameter than the main portion of the fiber. The isolated fiber segments usually comprise oriented polymer chains but differ in morphology from the main portion of the fiber.</p> |
