The present invention is a high capillary suction storage absorbent member comprising an agglomerate of particulate hydrogel-forming absorbent polymer and particulate high surface area open-celled hydrophilic foam. In another aspect of the invention the agglomerate of particulate hydrogel-forming absorbent polymer and particulate high surface area open-celled hydrophilic foam is disclosed. The absorbent member is useful in the containment (e.g., storage) of body liquids such as urine. In one embodiment, the storage absorbent member comprises the agglomerate. In another embodiment, the absorbent member comprises the agglomerate adjacent to at least one sheet, strip or piece of high surface area open-celled hydrophilic foam material. In either the storage absorbent member or agglomerates of the invention, the high surface area open-celled hydrophilic foam comprises from about 1% to about 98%, preferably from about 15% to about 85%, more preferably from about 30% to about 40% by weight of the member or agglomerate, respectively. An unique aspect of the agglomerates according to the present invention is that they are formed without the use of a separate bonding substance, such as an adhesive.
A high capillary suction storage absorbent member comprising an agglomerate of particulate hydrogel-forming absorbent polymer and particulate high surface area open-celled hydrophilic foam wherein the storage absorbent member has one or more of the following:
A high capillary suction storage absorbent member comprising an agglomerate of particulate hydrogel-forming absorbent polymer and particulate high surface area open-celled hydrophilic foam wherein the storage absorbent member has a capillary sorption absorbent capacity at a height of 50 cm of at least about 7 g/g.
A high capillary suction storage absorbent member comprising an agglomerate of a particulate hydrogel-forming absorbent polymer and a particulate high surface area open-celled hydrophilic foam, said storage absorbent member having a capillary sorption absorbent capacity at a height of 35 cm of at least about 12 g/g.
A high capillary suction storage absorbent member comprising an agglomerate of a particulate hydrogel-forming absorbent polymer and a particulate high surface area open-celled hydrophilic foam, said storage absorbent member having a capillary sorption absorbent capacity at a height of 0 cm of at least about 15 g/g and having one or more of the following:
A high capillary suction storage absorbent member comprising an agglomerate of a particulate hydrogel-forming absorbent polymer and a particulate high surface area open-celled hydrophilic foam, said storage absorbent member having a capillary sorption absorbent capacity at a height of 0 cm of at least about 15 g/g and having a medium absorption height of at least about 35 cm.
A high capillary suction storage absorbent member comprising an agglomerate of a particulate hydrogel-forming absorbent polymer and a particulate high surface area open-celled hydrophilic foam adjacent at least one sheet, strip or piece of high surface area open-celled hydrophilic foam.
An agglomerate comprising particulate hydrogel-forming a polymer and particulate high surface area open-celled hydrophilic foam wherein a plurality of the individual particles of said hydrogel-forming absorbent polymer have numerous particles of said high surface area open-celled hydrophilic foam bonded thereto to form said agglomerate wherein said agglomerate has one or more of the following:
A method for making an agglomerate comprising forming an agglomerate by pressing wetted particulate hydrogel-formimg absorbent polymer into particulate high surface area open-celled hydrophilic foam so as to bond numerous particles of said high surface area open-celled hydrophilic foam onto an individual particle of said hydrogel-forming absorbent polymer forming said agglomerate, wherein said agglomerate has one or more of the following:
An agglomerate of particulate hydrogel-forming absorbent polymer and particulate high surface area open-celled hydrophilic foam wherein said agglomerate has one or more of the following:
An agglomerate of particulate hydrogel-forming absorbent polymer and particulate high surface area open-celled hydrophilic foam wherein the agglomerate has a capillary sorption absorbent capacity at a height of 50 cm of at least about 7 g/g.
An agglomerate of a particulate hydrogel-forming absorbent polymer and a particulate high surface area open-celled hydrophilic foam, said agglomerate having a capillary sorption absorbent capacity at a height of 35 cm of at least about 12 g/g.
An agglomerate of a particulate hydrogel-forming absorbent polymer and a particulate high surface area open-celled hydrophilic foam, said agglomerate having a capillary sorption absorbent capacity at a height of 0 cm of at least about 15 g/g and having one or more of the following:
An agglomerate of a particulate hydrogel-forming absorbent polymer and a particulate high surface area open-celled hydrophilic foam, said agglomerate having a capillary sorption absorbent capacity at a height of 0 cm of at least about 15 g/g and having a medium absorption height of at least about 35 cm.
