摘要:
An absorbent article including a liquid-permeable top layer, an absorbent core layer, and a breathable outer cover is provided with a breathable inner laminate between the absorbent core and the outer cover. The breathable inner laminate includes a breathable film and a nonwoven filament web, and is at least as breathable as the outer cover. The breathable inner laminate substantially reduces perceived dampness occurring on the external surface of the outer cover, following a liquid insult, when the article is being worn, without substantially reducing moisture flux in use via thermal insulation.

Breathable microporous films are provided having controlled regional breathability with thick high WVTR regions and thinner low WVTR regions. The zoned breathable microporous films can be made by selectively applying heat and/or pressure to specific regions the microporous film such as by feeding a microporous film through a pair of heated nip rollers with one of the rolls having a raised surface area or by applying a focused stream of hot air. Monolayer microporous films and multilayer films having at least one microporous layer can be treated to impart zoned breathability to the film.

An absorbent article including a liquid-permeable bodyside liner, an absorbent core layer and a breathable outer cover is provided with a hydrophobic foam dampness-inhibiting layer between the absorbent core and the outer cover. The hydrophobic foam dampness-inhibiting layer maintains an air space within the foam. The air space acts as a thermal insulator, dampness-perception inhibitor and moisture passageway. The resulting product is an absorbent garment having a breathable outer cover material with reduced perception of dampness on the outer surface of the outer cover.

An absorbent article including a liquid-permeable top layer, an absorbent core layer, and a breathable outer cover is provided with a breathable inner laminate between the absorbent core and the outer cover. The breathable inner laminate includes a breathable film and a nonwoven filament web, and is less breathable than the outer cover. The low to moderately breathable inner laminate substantially reduces perceived dampness occurring on the external surface of the highly breathable outer cover, following a liquid insult, when the article is being worn, without seriously hampering moisture flux out of the diaper. Direct pathways for moisture near the wearer's skin to exit the article are maintained, and a concentration gradient is enhanced. Alternate embodiments include an apertured absorbent core, or the absence of a nonwoven filament web wherein the film and the absorbent core are apertured together, or a surge layer positioned between the top layer and the absorbent core wherein the surge layer extends to fill apertures in the absorbent core.

An absorbent article including a liquid-permeable top layer, an absorbent core layer, a breathable outer cover, and an inner nonwoven filament layer between the absorbent core and breathable outer cover. The outer cover includes a breathable film and an outer nonwoven filament layer. The inner nonwoven filament layer has a mean fiber denier which is higher than the mean fiber denier of the outer nonwoven filament layer. The inner nonwoven filament layer serves as a dampness inhibitor which reduces or prevents perceived dampness on the external surface of the outer cover by lowering thermal conductivity between the absorbent core and the outer cover surface.

Disclosed is a fabric which includes a microbial adsorbent and which is capable of providing a microbial barrier while still being able to allow passage of water vapor. The fabric is formed from a plurality of fibers which define at least one microporous passageway which allows communication, through the fabric, between its respective first and second surfaces. In particular, a portion of the microporous passageway is defined by the microbial adsorbent so that microbes attempting to pass through the fabric via such a passageway must pass in close proximity to the microbial adsorbent. This arrangement allows the microbial adsorbent to interdict the microbe by adsorbing it. Passage of the microbe through the fabric is thereby prohibited. Laminates of the fabric with other materials are also disclosed.

There is provided a BM containment system for personal care products having an expandable material which expands upon contact with fluids to form a compartment in which BM may be contained. The system may optionally have a dewatering layer on the side away from a wearer of the personal care product. The system may also be in liquid isolation from other personal care product components which are located on the side away from a wearer in order to keep the BM containment system from expanding from exposure to urine. Liquid isolation may be provided by a film between the other system components and the traditional personal care product components.
摘要:
An absorbent article including a liquid-permeable top layer, an absorbent core layer, a breathable outer cover, and a creped inner nonwoven fibrous layer between the absorbent core and breathable outer cover. The creped inner nonwoven fibrous layer has a level of creping of about 5-75%, and is preferably permanently creped. The creped inner nonwoven fibrous layer serves as a dampness inhibitor which reduces or prevents perceived dampness on the external surface of the outer cover by lowering thermal conductivity between the absorbent core and the outer cover surface.
摘要:
A nursing pad is disclosed having a liquid permeable body facing layer of a polyethylene/polypropylene bicomponent fiber web, an absorbent core comprising a composite fabric of thermoplastic fibers and an absorbent material, and a barrier laminate, such as a spunbond/meltblown/spunbond laminate or a spunbond/film laminate. The nursing pad can have a substantially concave shape, a thermally sealed edge and autogenous bonding to impart additional integrity to the three-dimensional shape.
摘要:
Disclosed is a film which includes a microbial adsorbent and which is capable of providing a microbial barrier while still being able to allow passage of water vapor. The film has first and second surfaces and defines least one microporous passageway allowing communication, through the film, between the first and second surfaces. In particular, a portion of the microporous passageway is defined by the microbial adsorbent so that microbes attempting to pass through the film via a passageway must pass in close proximity to the microbial adsorbent. This arrangement allows the microbial adsorbent to interdict the microbe by adsorbing it and prohibiting its passage through the film.
