Drypad with rapid absorption and liquid removal
Disclosed is a liquid removal drypad and liquid removal system suitable for absorbing and removing liquid produced by an individual. The drypad can include one or more perforated conduits arranged with an absorbent material. A source of reduced pressure can be connected to the one or more perforated conduits to remove liquid from the drypad. The drypad can be positioned under a patient and liquid produced by the individual can be removed by applying reduced pressure to the drypad. The drypad can be made by combining one or more conduits with an absorbent material.
Absorbent Article Comprising A Synthetic Polymer Derived from A Renewable Resource and Methods of Producing Said Article
A method for making a disposable absorbent article is provided. The method comprises the steps of providing a first nonwoven comprising synthetic fibers comprising a .sup.14C/C ratio of about 1.0×10.sup.−14 or greater, providing a second nonwoven comprising synthetic fibers comprising a comprising a .sup.14C/C ratio of about 1.0×10.sup.−14 or greater, converting the second nonwoven into a topsheet so that the topsheet comprises a Liquid Strike Through value of less than 4 seconds, and combining the first nonwoven and the topsheet with other absorbent article components to form a disposable absorbent article.
Absorbent Article Comprising A Synthetic Polymer Derived from A Renewable Resource and Methods of Producing Said Article
An absorbent article is disclosed having a topsheet, a backsheet joined with the topsheet, an absorbent core disposed between the topsheet and the backsheet, and a synthetic superabsorbent polymer derived from a first renewable resource via at least one intermediate compound, wherein said superabsorbent polymer exhibits a defined Saline Flow Conductivity value and Absorption Against Pressure value. Alternately, an absorbent article is disclosed having a synthetic polyolefin derived from a first renewable resource via at least one intermediate compound.

Material for absorbent article, method for manufacturing same, and absorbent article using same
The present invention discloses a material for an absorbent article, the material having an organic hydrophobic antimicrobial agent and a hydrophilic non-volatile organic solvent. The material for an absorbent article is preferably manufactured by a method having a step of applying an antimicrobial agent solution to a material for an absorbent article, the antimicrobial agent solution being formed by dissolving an organic hydrophobic antimicrobial agent in a hydrophilic non-volatile organic solvent. The present invention also discloses an absorbent article in which the material for an absorbent article is used. The absorbent article is preferably manufactured by using a method having a step of making an absorbent core contain an antimicrobial agent solution formed by dissolving an organic hydrophobic antimicrobial agent in a hydrophilic non-volatile organic solvent.
Method and device for manufacturing absorber
A manufacturing device is provided, within a range in the rotation direction of the upper half of an anvil roll, in the order from the upstream side in the rotation direction of the anvil roll, with a first sheet feeding unit, a recess forming unit, a particulate material feeding device, and a second sheet feeding unit and further a welding unit provided on the downstream side of the second sheet feeding unit in the rotation direction. The anvil roll has a large number of concaves, projections provided in a portion among the concaves, so as to surround each of the concaves, and a unit to suck air in the concaves. For each concave, the projections are minute dot-shaped projections arranged only in one row at intervals in the direction surrounding the concave.
ABSORBENT CORE AND ABSORBENT ARTICLES COMPRISING SAID CORE

Absorbent article and method of manufacturing same
An absorbent article has an absorbent body obtained by mixing and accumulating fibers and high absorbent polymer particles. A wrapping sheet includes an intermediate part located on a front face side of the absorbent body and both side parts folded back to a back face side of the absorbent body from the intermediate part. Distal ends of the both side parts of the wrapping sheet are overlapped on the back face side of the absorbent body to form a connecting portion. A total weight of the high absorbent polymer particles is larger than a total weight of the fibers in the absorbent body. A content rate of the high absorbent polymer particles of the absorbent body increases stepwise or continuously from the back face side toward the front face side.
