Abstract

A sanitary napkin is disclosed which has an absorbent and a fluid-permeable cover positioned over at least one surface of the absorbent. The cover is formed from a nonwoven web having a network of essentially unbroken thermoplastic fibers. The web has a plurality of apertures formed therethrough which are located in a predetermined area which represents less than about 80% of the surface area of the cover. Each of the apertures is surrounded by a consolidated ring formed of thermally set thermoplastic fibers which in turn is surrounded by a raised area which contacts the body of the user. The apertures formed in the web occupy about 20% to 55% of the predetermined area and permit body fluid to quickly pass through to the absorbent.
