摘要： Absorbent structures and methods of manufacture are disclosed. In one embodiment, an absorbent structure may comprise first and second substrate material layers and a mixture of superabsorbent particles and adhesive disposed between the first and second substrate material layers. The superabsorbent particles may be disposed in an amount greater than 400 gsm, and the adhesive may be disposed in an amount less than 5%, by weight, of the weight of the superabsorbent particles, and the adhesive forms a three-dimensional mesh network comprising network adhesive filaments with the superabsorbent particles immobilized within the mesh network, and the network adhesive filaments extending substantially throughout a three-dimensional space defined by the network adhesive filaments and the superabsorbent particles.

摘要： An absorbent article having improved handling of body exudates. The absorbent article can minimize the amount of body exudates in contact with a wearer's skin and can minimize the incidence of leakage of body exudates from the absorbent article. The benefits of the absorbent article are achieved, in part, by a body facing material having features that help minimize contact of body exudates with the wearer's skin while also being constructed so that the body facing material does not stick to the wearer's skin in use. The body facing material includes a plurality of hollow projections, a plurality of apertures and bonded areas. The bonded areas may be formed with adhesive or by mechanical bonds.

摘要： A process for splicing a first portion (22) of absorbent material (20) to a second portion (24) of absorbent material (20) to form a longer, continuous length of absorbent material suitable for uninterrupted sequential infeed to a processing machine. The process includes the steps of placing a trailing end (26) of the first portion adjacent a leading end (28) of the second portion and aligning the ends. A piece of splicing material (40) is attached to the ends. The piece of splicing material (40) has a fluid permeability at least about as great as a fluid permeability of the first portion(22) of absorbent material and at least about as great as a fluid permeability of the second portion (24) of absorbent material. In other aspects, the disclosure includes a spliced, continuous length of absorbent material, and a personal care absorbent article formed from the spliced absorbent material.

摘要： An absorbent article having a liner and an outer cover in generally opposed relationship with the liner. An absorbent body disposed therebetween includes a non-woven absorbent structure having a length, a width and a thickness. The absorbent structure is constructed of absorbent fibers and binder fibers activatable to form inter-fiber bonds within the absorbent structure, with the binder fibers being multi-component fibers in which at leastone binder fiber component has a melt temperature that is lower than a melt temperature of at least one other binder fiber component. The width of the absorbent structure is non-uniform along its length prior to activation of the binder fibers. In another embodiment, the absorbent structure is of unitary construction and the concentration of binder fibers therein is non-uniform along at least one of the length, the width and the thickness of the absorbent structure.

摘要： The present invention is directed to a process and apparatus for formation of a fluid-entangled laminate web. The laminate web includes a support layer and a nonwoven projection web having a plurality of projections which are preferably hollow. The laminate web also includes a plurality of apertures interspersed with the projections. As a result of the fluid-entangling process, entangling fluid is directed through the support layer and into the projection web which is situated on a forming surface. The force of the entangling fluid causes the two layers to be joined to one another and the fluid causes a portion of the fibers in the projection web to be forced into openings present in a forming surface thereby forming the hollow projections. The force of the entangling fluid also causes the fibers of the two layers to be moved around protrusions present in the forming surface thereby forming the apertures.
