Abstract

A method for making an apertured nonwoven fabric includes the steps of: obtaining wet sheet from slurry containing 0.5 - 20 % by weight of fibrous component in water, which comprises, in turn, thermoplastic synthetic fibers having a length of 7 - 30 mm and a fineness of 0.1 - 0.8 d, and subjecting the wet sheet to a processing for fiber entangling by high velocity water jet streams and to a processing for aperture forming by aperture forming elements having predetermined configurations adapted to be followed by individual fibers.
