摘要:
Disclosed are absorbent cores for inclusion in articles such as diapers, incontinent briefs, training pants, diaper holders and liners, feminine hygiene garments, and the like, designed to provide improved fit and comfort for the wearer while adequately containing body exudates. The absorbent core is designed so as to retain low levels of fluid in the crotch region, relative to the other core regions, even when the core absorbs significant amounts of fluid during use. To achieve this, the absorbent core is designed such that fluid is moved substantially from the crotch region to the front and/or rear ends of the article. In particular, the absorbent core comprises in its crotch region a material having significant vertical wicking absorbent capacities.

摘要:
Disclosed is a shaped absorbent core suitable for absorbing and retaining aqueous body fluids. The absorbent cores comprise a front panel and a back panel. The front and back panels are made from fluid absorbent material, and each has an inner end, an outer end, and two sides. The inner and outer ends of each front and back panel have a length, with the inner end of each being shorter than the outer length of each. The front and back panels may comprise multiple layers of absorbent material. The absorbent cores also comprise a center section made from fluid absorbent material having first and second ends. The first end of the center section is in fluid communication with the front panel by overlapping the front panel intermediate the front inner and outer ends, and the second end is in fluid communication with the back panel by overlapping the back panel intermediate the back inner and outer ends. A method of preparing a shaped absorbent core comprises the steps of providing at least one continuous rectilinear web of first absorbent material having a longitudinal axis and a pair of lateral edges defining a first width. A continuous rectilinear web of second absorbent material having a longitudinal axis and a pair of lateral edges defining a second width wider than the first width of the first absorbent material is formed with opposing generally arcuate notched areas in the lateral edges at spaced intervals along the web of second absorbent material. The web of second absorbent material is severed transversely along a line intersecting the opposed generally arcuate notched areas at spaced intervals to form sections having opposed notched ends The sections are then positioned such that the notched ends are spaced apart and overlap the continuous rectilinear web of first absorbent material, forming layers of absorbent material. Then the layers of absorbent material are severed transversely at a point intermediate the notched ends.
摘要:
An apertured polymeric film web having a first surface, a second surface generally parallel to and spaced apart from said first surface, and a plurality of fluid passageways extending between the first surface and the second surface to place the first surface and the second surface in fluid communication with one another. The web is formed of a polymeric film comprising at least one bulk modified layer, the bulk modified layer comprising a substantially homogeneous, stabilized dispersion comprising a comparatively low surface energy material in a polymeric material. The comparatively low surface energy material, referred to herein as a hydrophobic additive, imparts hydrophobicity to the web's first surface, thereby promoting enhanced effectiveness in transporting fluid away from the first surface of the web, particularly when used in combination with a hydrophilic adhesive applied to the web's second surface in a topsheet system of the present invention.
