Abstract: The present invention relates to a method of forming a nonwoven fabric, and more specifically to a nonwoven fabric comprised of hydroentangled continuously extruded, essentially endless thermoplastic polymer nano-denier filaments. The polymeric nano-denier filaments can be provided in the form of one or more precursor webs, or the process can be practiced in-line process. Fabrics embodying the present invention may comprise laminations of differing polymeric filaments, such as filaments exhibiting significantly differing bonding temperatures.

Abstract: The present invention is directed to a modular die unit comprising a plurality of individually shaped plates wherein the shaped plates are stacked in face to face juxtaposition, and when placed into such a juxtaposition exhibit useful polymer forming attributes heretofore unattainable by prior art practices. Single die plates are formed such that the plates exhibit a finite geometric relationship, which in turn provides resistance to flexural deformation of the individually shaped die plates and conversely, improved resistance to variability of the modular die unit and enhanced and predictable formation characteristics of the polymer material formed therewith. Each of said single die plates within the stack forming the modular die unit exhibit an x-direction, a y-direction, and a z-direction, wherein any one of said single die plates exhibit in said x-direction and y-direction to have at least a 50% planar continuity of the total planar continuity.

Abstract: The present invention is directed to nonwoven barrier fabrics, and more specifically, to medical, hygiene and industrial articles comprised of nonwoven compound fabrics with improved barrier to basis weight performance, wherein the improved nonwoven compound fabrics are prepared by forming an intermediate nonwoven construct by supplying a strong and durable substrate layer followed by deposition of a frangible fibrous layer onto the substrate layer thereby providing nonwoven barrier materials. The so formed intermediate construct is subsequently subjected to mechanical energy which induces the frangible fibrous layer to fragment into sub-fibers exhibiting an equivalent denier as the frangible fibrous component, said sub-fibers becoming inter-engaged in the strong and durable substrate layer, thereby providing nonwoven barrier materials exhibit useful barrier performance.
