APPENDIX
1. A unitized absorbent structure having respective cover,
transfer, and reservoir layers, characterized in that:
a) at least two of said respective layers are in physical
contact with one another such that fluid transfer is
promoted therebetween;
b) said respective layers have a predetermined positive
density gradient from the cover layer to the reservoir
layer;
c) each of said layers has preselected fluid retention and
transfer capacity;
d) said cover and transfer layers tend to promote transfer
to the next subsequent layer in preference to dispersion of
fluid over their length and breadth, while said reservoir
layer tends to promote dispersion and retention of fluid
throughout its length and breadth,
e) said transfer layer comprises hydrophilic material, and
f) said fluid reservoir layer has a pore size distribution
in the wet state such that between about 90% and 100% of the
pores are less than 300 Fm in radius and about between 0%
and 10% of the pores are greater than 300 Fm in radius.
