A bodyside cover for an absorbent article is disclosed which includes two different materials to provide enhanced functionality. The bicomponent cover includes an apertured first material, which is positioned along the longitudinal central axis of the absorbent article, and a nonperforated second material secured to at least a portion of the first material. The first material has a rewet value which is less than, or equal to, the rewet value of the second material while the second material is softer than the first material. The first material is positioned below the principal point of fluid discharge and represents the primary fluid-receiving region of the cover. The second material is situated away from the principal point of fluid discharge and represents the secondary fluid-receiving region of the cover.

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.

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.

A sanitary napkin having a gas permeable nonwoven baffle is provided in which a composite baffle is formed by joining webs of a meltblown polyolefin and a spunbonded polyolefin with the spunbonded polyolefin web providing a surface for garment attachment adhesive reception.

Breathable baffle composite

A sanitary appliance is provided which has fused barrier lines in the cover only. The web is useful as a wrap for absorbent appliances or for toweling in which the fused barrier in each instance minimizes surface runoff and excessive wicking. The invention also includes a process for making a sanitary appliance with the web of the subject invention.

Fluid pervious thermoplastic containing web with fused barrier lines

A flexible convolutely wound paper tampon tube is provided in which a thermoplastic coating on either the interior or the exterior portion of the tube is present in an amount to maintain the tube configuration.
