Abstract
A system and method for providing a plurality of fibers from a spinneret; subjecting the fibers to quench air; attenuating the fibers through a closed stretching unit; reducing a velocity of the plurality of fibers in a diffuser that is spaced apart from an exit of the closed stretching unit in a direction of travel of the fibers, the diffuser having opposed diverging sidewalls; and subjecting the fibers to an applied electrostatic charge before the fibers enter the diffuser, wherein the electrostatic charge is applied by one or more electrostatic charging units.
