Abstract
A process of forming a nonwoven fabric is disclosed which comprises the steps of forming a precursor web of multicomponent substantially continuous filaments, exposing the precursor web to a hydraulic arrangement treatment to form apertures without causing substantial filament entanglement, and thereafter forming inter-filament bonds and an integrated web. The resulting apertured nonwoven fabrics have good hand and tactile aesthetics and have a great variety of uses including use in absorbent personal care products, garments, medical applications, and cleaning applications.
