Method of perforating a nonwoven web and use of the web as a cover for a feminine pad

摘要

A method of perforating a nonwoven web of fibrous fabric by directing the web through a nip defined by first and second moveable members. As the web moves through the nip it is penetrated by a plurality of heated pins projecting from the first member which enter heated apertures formed in the second member. The penetration of the pins causes the fibers of the fabric to separate and enter into the apertures and form openings through the web. The openings are surrounded by dense consolidated rings exhibiting greater hydrophilic properties than the nonperforated surface of the web.
