Abstract
There is disclosed a porous non-woven absorbent structure formed from fibers. The porous structure has a basis weight within the range of at least about 0.25 osy to about 10.0 osy a density of at least about 0.01 g/cc to about 0.15 g/cc. The porous structure is adapted such that upon the application of at least 2 ml of fluid Bovine blood-oxalate to a surface thereof, substantially all of said fluid enters the bulk of the porous structure within about 45 seconds. The porous structure may be single layered or include multiple layers. The single layered structure is formed from spunbonded thermoplastic fibers which include a hydrophilic internal additive. The multiple layered structure is formed by laminating a spunbonded web to a second layer. The second may be formed from natural or synthetic fibers. When formed from synthetic fibers, the second layer is generally formed from meltblown fibers which may also include a hydrophobic internal additive. The fibers forming either the spunbond or the meltblown layers may be mono-component or bi-component. In some applications, a liquid impervious film may be secured to a surface of the second layer.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
