Abstract: A system having a first polymer source and a spin beam in fluid communication with the first polymer source is provided. The spin beam includes a spinneret assembly having filament nozzles configured and arranged to extrude a plurality of filaments of a first polymer. A gas distribution plate is disposed downstream of the spinneret assembly, and includes a plurality of gas distribution slots that are configured and arranged to receive two or more corresponding filament nozzles of the spinneret assembly therein. A stream of gas is introduced into the plurality of slots to draw and attenuate the filaments extruded by the plurality of filament nozzles. The drawn and attenuated filaments are collected on a collection surface disposed downstream of the gas distribution plate to form a nonwoven fabric. A solid additive, such as pulp fibers may be blended with the filaments prior to collecting the filaments on the collection surface.

Abstract: One or more aspects of the disclosure provides a nonwoven fabric comprising a single layer in which the single fabric layer comprises a plurality of different fibers in which each fiber type has desired functionality. In one aspect, a system for preparing a nonwoven fabric having a single fabric layer in which the single fabric layer comprises a plurality of different fiber types, is provided. The system includes a spin beam having a zoned distribution plate disposed upstream of a spinneret, the zoned distribution plate includes a plurality of distribution apertures arranged in zones, wherein each zone is configured and arranged to extrude a plurality of polymer streams that are of a different polymer type than polymer streams extruded by an adjacent zone to the spinneret to form a single layer having two or more types of fibers that are of a different type from each other.
