摘要： A system and associated method for preparing a composite sheet material is provided. The system includes a nonwoven fabric source; a collection surface onto which a nonwoven fabric is deposited; a carding device disposed downstream of the nonwoven fabric source overlying the collection surface, the carding device including a main cylinder, an air source configured to provide a stream of air; an air manifold having an air inlet in communication with the air source, an air outlet, a fiber inlet, an interior channel, and a fiber outlet. The air outlet is positioned to direct an air stream against a surface the cylinder to dislodge fibers from the surface of the cylinder. The dislodged fibers enter the fiber inlet and flow to the fiber outlet at which point the fibers are deposited onto a surface of the nonwoven fabric. The fabrics are then bonded to form a coherent sheet material.

摘要： 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.
