Abstract: Absorbent structures having a wetlaid fluid acquisition/distribution layer (110) with an average dry density of less than about 0.30 g/cc, an average density upon wetting with 1.0 % NaCl aqueous solution of less than about 0.20 g/cc, and an average dry basis weight from about 0.001 to about 0.10 g/cm2; and a fluid storage layer (108) positioned beneath the acquisition/distribution layer (110) comprising at least about 15 % superabsorbent material. The fluid acquisition/distribution layer (110) comprises from about 50 % to 100 % chemically stiffened cellulosic fibers and from 0 % to about 50 % binding means.

Abstract: Various stiffness characteristics of removable and replaceable absorbent core components used with disposable absorbent articles are disclosed. The replaceable core component can be constructed with bending stiffness characteristics making it easier to install in a diaper chassis. In other instances, a relatively stiff insertion tool may also be used to engage a relatively flexible replaceable core component to aid with insertion of the replacaeable core component into the diaper chassis. Aspects of the present disclosure involve replaceable core components alone or in combination with insertion tools having bending stiffness characteristics that reduce the likelihood of buckling and/or folding while installing the replaceable core component into the diaper chassis. The present disclosure also provides methods for testing replaceable core components and/or insertion tools to evaluate the bending stiffness characteristics associated therewith.

Abstract: SE DESCRIBEN ESTRUCTURAS ABSORBENTES QUE INCLUYEN UNA PRIMERA CAPA, UNA SEGUNDA CAPA YUXTAPUESTA EN RELACION OPUESTA CON DICHA PRIMERA CAPA, SIENDO AL MENOS UNA DE LAS CAPAS PERMEABLE A FLUIDOS. ESTAS ESTRUCTURAS TAMBIEN PRESENTAN UNA REGION CONTINUA ENTRE DICHA PRIMERA Y SEGUNDA CAPA FORMADA POR UN POLIMERO FORMADOR DE HIDROGEL QUE ESTA DISTRUIBUIDO DE FORMA SUSTANCIALMENTE UNIFORME A LO LARGO DE LA REGION. LA REGION CONTINUA RODEA AL MENOS PARCIALMENTE MULTIPLES ZONAS ESPACIADAS ENTRE SI QUE SE ENCUENTRAN ENTRE DICHAS CAPAS, ESTANDO DICHAS ZONAS SUSTANCIALMENTE EXENTAS DE POLIMERO ABSORBENTE FORMADOR DE HIDROGEL. LA PRIMERA Y SEGUNDA CAPA ESTAN UNIDAS ENTRE SI DE FORMA QUE DICHO POLIMERO ABSORBENTE FORMADOR DE HIDROGEL SE ENCUENTRA SUSTANCIALMENTE INMOVILIZADO CUANDO SE ENCUENTRA EN ESTADO SECO, PREFERIBLEMENTE EN SITIOS DENTRO DE UNA PLURALIDAD DE ZONAS. PREFERIBLEMENTE, EL POLIMERO ABSORBENTE FORMADOR DE HIDROGEL PRESENTA UNA PERMEABILIDAD DE GEL RELATIVAMENTE ELEVADA, DE MANERA QUE FORMA UNA CAPA DE TRANSPORTE DE LIQUIDO DE GEL CONTINUO.

Abstract: The present invention relates to absorbent articles suitable for absorbing and retaining aqueous body fluids. Absorbent articles of the present invention comprise a discontinuous, substantially fluid impervious backsheet and an absorbent core disposed between the topsheet and the backsheet. The absorbent core comprises a plurality of core components which are removable, with access for removal provided by at least one discontinuity forming an opening in the backsheet. Once removed, other absorbent core components or layers of components may remain in the absorbent article. Also, additional absorbent core components or layers may be added through the opening in the backsheet. In a preferred embodiment the absorbent core comprises a plurality of components, including at least a front panel, a rear panel, and a center section. Each of the absorbent components may include layers of absorbent members. Upon saturation with bodily discharges certain components or members of the absorbent core may be removed from the absorbent article through the backsheet. New, unsaturated absorbent components or members may then be positioned in place of the removed saturated components or members, or, more preferably, upon removal of the saturated component or member, an additional unused component or member may remain in position for use.

Abstract: Described are absorbent members useful in the containment of body liquids such as urine. These absorbent members comprise at least one osmotic absorbent (preferably a hydrogel-forming absorbent polymer) and a high surface area material, and have a high capillary suction capacity. For purposes of the present disclosure, capillary suction capacity is measured in terms of the member's ability to uptake liquid at high capillary heights, which are generally encountered when the member is positioned in an absorbent article. In particular, capillary suction capacity is measured in terms of a member's capillary sorption absorbent capacity, which is measured in accordance with the Capillary Sorption method described in the Test Methods section.

Abstract: A disposable absorbent article adapted to be worn about a lower torso of a human body and having a chassis, a non-removable absorbent core component disposed in a crotch region of the chassis, and a replaceable absorbent core component disposed in capillary liquid communication with the non-removable absorbent core component. The replaceable absorbent core component may be removed and a like component may be substituted in place of the removed component without the removal of the absorbent article from the wearer. The replaceable absorbent core component may be disposed inside an openable chassis pocket, with access for its removal and replacement provided by an aperture in a backsheet, an openable end of an external pocket, or an openab le end of an internal pocket formed at an area of a waist end edge where the backsheet and a topsheet may be separated. Additional replaceable absorbent core components may also be incorporated.
