Abstract: A method for producing an apertured structured material for accommodating passage of fluids, particularly high viscosity fluids, through the apertured structured material. In one embodiment, the apertured structured material is a composite material formed by differential shrinkage of a shrinkable second layer, for example an ethylene-propylene copolymer, which is laminated to a first layer, for example a polypropylene polymer. During the differential shrinkage process, a plurality of slits which are formed in the second layer open to form uniformly-shaped apertures. In another embodiment, an apertured structured heterogenous material is made of a heterogeneous mixture of at least two homogeneous fiber sets or components having different shrinkage extents.

Abstract: A method for producing a structured material for accommodating passage of fluids, particularly high viscosity fluids, through the structured material. In one embodiment, the structured material is a composite material formed of a first layer, for example a polypropylene polymer, having a first shrinkage extent and a second layer bonded to the first layer, for example an ethylene-propylene copolymer, having a second shrinkage extent different from the first shrinkage extent. In another embodiment, a structured heterogenous material is made of a heterogeneous mixture of at least two homogeneous fiber sets or components having different shrinkage extents.

Abstract: A composite fabric comprising a necked and creped spunbond nonwoven web of monocomponent fibers hydraulically entangled with a fibrous component that comprises cellulosic fibers. The nonwoven web contains thermoplastic fibers and the fibrous component comprises greater than about 50% by weight of the fabric.

Abstract: There is provided a resilient, three dimensional material having fibrous texture and appearance and capable of fluid handling. It consists of a top surface and a bottom surface wherein fiber-like elements typically extend from one surface to the other forming flat to undulating surfaces characterized by a multiplicity of interconnected fluid passageways. Deformed, discontinuous film-like or encapsulated regions connect fiber-like elements and stabilize the material. The material of this invention is unique based on the three principle characteristics which are communicated in this application: 1) ff(?)<0.87, 2) SA/VV<186 cm2/cm3, and 3) caliper<0.150 inches. This material is useful for a number of purposes, such as for use as a liner for personal care products like diapers, absorbent underpants, swim wear, feminine hygiene products, adult incontinence products and the like.

Abstract: There is provided a new nonwoven material for personal care products made of fibers, binder in an amount between 1 and 6 weight percent and superabsorbent in an amount between 1 and 80 weight percent, where the superabsorbent is contained in micro-pockets in the nonwoven. These micro-pockets may be made by creping a nonwoven fabric, orienting fibers in the Z-direction, and by passing a relatively lofty nonwoven fabric between unheated thermal pattern bond and anvil rolls. These materials exhibit good permeability to liquid in the pre- and post-wetted conditions, thus avoiding gel blocking and other negative effects of superabsorbent swelling within a fabric. Such a fibrous material is useful in personal care products, like diapers, training pants, incontinence garments and feminine hygiene products.

Abstract: An absorbent article including a breathable outer cover, a topsheet, an absorbent core disposed between the topsheet and the breathable outer cover, and a porous separation layer disposed between the absorbent core and the breathable outer cover is disclosed. The porous separation layer includes a plurality of wettable pores originating on a first surface of the porous separation layer adjacent the absorbent core and a plurality of larger wettable pores originating on a second surface adjacent the breathable outer cover.

Abstract: 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.

Abstract: A personal care absorbent article having a fluid intake/distribution layer, a fluid transfer delay layer disposed beneath said fluid intake/distribution layer, said fluid transfer delay layer enabling the transfer of fluid from the fluid intake/distribution layer(s) to a pad layer disposed beneath the fluid transfer delay layer while still allowing fluid distribution by the fluid intake/distribution layer along the machine direction of the article resulting in saturation levels of less than or equal to about 0.86 g/g/in of fluid in the intake/distribution layer(s) and/or essentially equal to or greater than 0.06 g/g/in. of fluid in the pad layer.

Abstract: The present invention relates to an absorbent article for absorbing fluids and exudates, such as urine. More particularly, the present invention relates to absorbent garments which are configured to absorb body exudates while also helping to reduce the relative humidity in the environment of the article, to reduce skin-exudate contact and to reduced undesired skin hydration.

Such an absorbent system may be used in personal care products like diapers, training pants, feminine hygiene products, absorbent underpants, adult incontinence products, and the like.

Abstract: A creped nonwoven web having permanent crepe includes regions of interfilament bonding which are permanently bent out-of-plane, alternating with regions of no interfilament bonding. The non-bonded regions include a multiplicity of filament loops which terminate at both ends in the creped interfilament-bonded regions.
