Claim 2:
3. A system for preparing a nonwoven fabric comprising:
a first polymer source;
a spin beam in fluid communication with the first polymer source, the spin beam including a spinneret assembly having a plurality of rows of filament nozzles that are arranged in an array, the filament nozzles being configured and arranged to extrude a plurality of filaments comprising a first polymer provided by the first polymer source;
a gas distribution plate disposed downstream of the spinneret assembly, the gas distribution plate including a plurality of gas distribution slots that are each associated with one or more of the rows of the filaments nozzles;
a gas source in fluid communication with the plurality of gas distribution slots such that a stream of gas is introduced into the plurality of gas distribution slots to draw and attenuate the filaments extruded by the plurality of filament nozzles; and
a collection surface disposed downstream of the gas distribution plate for collecting the drawn and attenuated filaments thereon to form a nonwoven fabric,, wherein the plurality of gas distribution slots are disposed adjacent to a corresponding row of filament nozzles, and wherein the spin beam comprises an alternating pattern of rows of filament nozzles and gas distribution slots.
