Abstract

The present invention is directed to a process for producing continuous filament nonwoven fabric which comprises the steps of providing a single polymeric resin having an MFR of between about 6 to 16, spinning said single polymeric resin using commercially available continuous filament spinning equipment, to yield a continuous filament nonwoven fabric exhibiting a tensile strength improvement of at least 30% when compared to similar resin of greater than 35 MFR.
