Abstract:
A feminine care absorbent article comprising an absorbent member positioned between a topsheet and a baffle is provided. The absorbent member contains at least one layer that comprises superabsorbent particles containing nanopores having an average cross-sectional dimension of from about 10 to about 500 nanometers.
Abstract:
An absorbent article having a transfer layer is disclosed. The transfer layer is positioned between the cover and absorbent and has a mean free path ranging from about 50 microns to about 200 microns. In a preferred embodiment the transfer layer is composed of substantially a cellulosic material. Advantageously, the transfer layer is effective in distributing both the fluid-like and viscous constituents of body fluids such as menses permitting greater utilization of the absorbent capacity of the absorbent article.
Abstract:
Absorbent body in an absorbent product such as a diaper, incontinence pad, sanitary napkin or the like, and which comprises a liquid acquisition portion (13; 11, 13) and a liquid storage portion (12) adjacent thereto. The liquid acquisition portion has at least one well (13) which is located at the assumed wetting area of the absorbent body and extends into and through the liquid storage portion (12) and is in liquid communication with a liquid wicking layer (14) arranged under the liquid storage layer (12). The material in the liquid acquisition portion (13; 11, 13) has a mean pore size which is greater than the mean pore size in the liquid storage portion (12). The absorbent body has a high instantaneous absorption even during repeated wetting and a low rewetting.
Abstract:
An absorbent article for the management of body exudates having in combination, an acquisition component and a storage component. The acquisition component, interposed between the source of body exudates and the fluid storage component, has a member for fractionating body exudates emanating from the source and for storing the solid portion of the body exudates. The acquisition component has a plurality of pores in the size range of red blood cells, suspended solids, and other body exudates which traps, and stores the solid portion of body exudates and allows the fluid portion to continue flowing through the acquisition component and into the storage component. The storage component is for storing the fluid portion of the body exudates.
Abstract:
A stretchable absorbent garment having a fluid-pervious inner layer, an outer layer, and an absorbent structure located between said inner and outer layers, and at least two generally parallel elastomeric strands stretch bonded to the garment along its length such that when in a relaxed state, all of the above described elements are reduced in length.
Abstract:
This application relates to the use of slitted regions in absorbent members formed of absorbent materials that remain relatively thin until wetted with such fluids. Suitable materials include presently preferred varieties of polymeric foam materials. Single and multi-layered absorbent members incorporating slitted regions are disclosed, as well as the use of pre-formed cup-shaped slits for enhanced initial fluid acquisition. Such slitted regions in combination with planar expansion properties enable the absorbent members to respond dynamically to various fluid loading conditions to create useful structural features. The slitted regions, in combination with absorbent materials having expansion potential in at least one direction within the plane of the absorbent member, cause the slitted regions to buckle and/or deform out of the plane of the absorbent member, thereby causing the slit surfaces to displace angularly and/or translationally with respect to one another. This more fully exposes the slit surfaces to the incoming fluid for improved acquisition capabilities. The use of pre-formed cup-shaped slits enables the absorbent member to more quickly capture and absorb aqueous body fluids, and is particularly useful for containment and dewatering of moist or runny fecal material and higher viscosity fluids and/or those having a higher concentration of particulate material therein such as blood, menses, or wound fluids.
Abstract:
A distinctive absorbent article includes an absorbent body composed of a substantially hydrophilic material which is capable of absorbing a selected liquid. A liquid permeable topsheet layer composed of a substantially hydrophobic material is superposed in facing relation with said absorbent body and has an effective average pore size therein. A liquid permeable transport layer is located between the topsheet layer and the absorbent body, and is composed of a material which is less hydrophilic than the absorbent body and has an effective average pore size therein which is smaller than the pore size of the topsheet layer.
Abstract:
An absorbent article includes an absorbent structure. The edge portions in the absorbent structure's middle portion have a first mean pore size, and the central portion in the middle portion of the absorbent structure has a second mean pore size, the first mean pore size being greater than the second mean pore size. The absorbent article can be folded along the longitudinal centre axis so that a part of the article on one side of the longitudinal centre line and a corresponding part of the article on the other side of the longitudinal centre line are brought together to lie against one another at a plane of the longitudinal centre line on the upper surface of the article. The edge portions which have the greater, first mean pore size thereby form an area of the absorbent article that is first wetted during use.
Abstract:
This invention is a surge material having permanent storage properties that results in faster intake and greater saturation capacity and reduced fluid flowback. More specifically the invention is a surge material with a superabsorbent material printed on in a pattern of discrete regions. The objective of the invention is obtained by printing, or other known application process, a liquid superabsorbent precursor solution containing a crosslinkable composition onto a surge material and then curing the printed surge material to crosslink the polymers to get a surge material having discrete regions of superabsorbent material in the surge material. This invention is also useful in making an absorbent core of an absorbent article with improved strength, increased absorbency, and decreased shedding of superabsorbent material.
Abstract:
An absorbent article has a topsheet, an absorbent core and an acquisition/distribution transfer system disposed intermediate the topsheet and the absorbent core. The system includes at least one apertured material which is three dimensional and defines pores extending appreciably beyond the primary plane of the material in a direction from the absorbent core toward the topsheet. Preferably the pores taper inwardly from the core toward the topsheet.
