Definitions

  • One optional component of the absorbent core according to the present invention is a primary fluid distribution layer and a secondary fluid distribution layer.
  • the primary distribution layer typically underlies the topsheet and is in fluid communication therewith.
  • the topsheet transfers the acquired fluid to this primary distribution layer for ultimate distribution to the storage layer.
  • This transfer of fluid through the primary distribution layer occurs not only in the thickness, but also along the length and width directions of the absorbent product.
  • the also optional but preferred secondary distribution layer typically underlies the primary distribution layer and is in fluid communication therewith. The purpose of this secondary distribution layer is to readily acquire fluid from the primary distribution layer and transfer it rapidly to the underlying storage layer. This helps the fluid capacity of the underlying storage layer to be fully utilised.
  • the fluid distribution layers can be comprised of any material typical for such distribution layers. In particular fibrous layers maintain the capillaries between fibers even when wet are useful as distribution layers.
  • Fluid Storage Layer Positioned in fluid communication with, and typically underlying the primary or secondary distribution layers, is a fluid storage layer.
  • the fluid storage layer can comprise any usual absorbent material or combinations thereof. It preferably comprises absorbent gelling materials in combination with suitable carriers.
  • the storage layer can nevertheless be locally homogenous, i.e. have a distribution gradient in one or several directions within the dimensions of the storage layer.
  • Non-homogeneous distribution can also refer to laminates of carriers enclosing absorbent gelling materials partially or fully.
  • c Optional Fibrous ("Dusting") Layer An optional component for inclusion in the absorbent core according to the present invention is a fibrous layer adjacent to, and typically underlying the storage layer. This underlying fibrous layer is typically referred to as a "dusting" layer since it provides a substrate on which to deposit absorbent gelling material in the storage layer during manufacture of the absorbent core.
  • this fibrous "dusting” layer need not be included.
  • this "dusting” layer provides some additional fluid-handling capabilities such as rapid wicking of fluid along the length of the pad.
  • the absorbent core according to the present invention can include other optional components normally present in absorbent webs.
  • a reinforcing scrim can be positioned within the respective layers, or between the respective layers, of the absorbent core.
  • Such reinforcing scrims should be of such configuration as to not form interfacial barriers to fluid transfer. Given the structural integrity that usually occurs as a result of thermal bonding, reinforcing scrims are usually not required for thermally bonded absorbent structures.
  • Exemplary polyethylene films are manufactured by Clopay Corporation of Cincinnati, Ohio, under the designation P18-0401 and by Ethyl Corporation, Visqueen Division, of Terre Haute, Indiana, under the designation XP-39385.
  • the backsheet is preferably embossed and/or matt finished to provide a more clothlike appearance. Further, the backsheet can permit vapours to escape from the absorbent structure, i.e. be breathable, while still preventing extrudates from passing through the backsheet. Also breathable backsheets comprising several layers, e.g. film plus non-woven structures, can be used.
  • the water impermeable inner backsheet is then put back into its original position and the wrap around perforated coverstock is sealed along the cut by means of a e.g. a double sided adhesive tape.
  • Samples were produced using the method above, containing the odour control systems as described hereinbelow.
