Abstract:
A method of forming a non-woven web from extruded polymer fibers, the method comprising the steps of:(a) extruding a plurality of polymer fibers from an output of a spinneret; (b) directing the extruded fibers from the spinneret output to an input of an aspirator, wherein the aspirator input is positioned at a selected spinning distance from the spinneret output; (c) drawing the fibers through an aspirator to thereby attenuate the fibers; (d) deflecting the attenuated fibers in a direction that is non-parallel relative to a direction at which the fibers enter the aspirator input; (e) depositing the deflected fibers onto a forming surface to form a non-woven fibrous web; and (f) adjusting the spinning distance by relatively moving the spinneret and the aspirator toward or away from each other.
