Abstract
Abstract An absorbent web formed from inflated cellulose fibers said webs possessing improved vertical wicking properties compared to a similar web of cellulose fibers. The webs have been found to be particularly well suited for use in forming absorbent products such as diapers and the like. In one aspect of the present invention, the inflated cellulose fibers are generally free of a surface finish. In a second aspect the inflated cellulose fibers are crosslinked.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
68 words
An absorbent web of a material, said material comprising inflated cellulose fibers, said fibers being formed from regenerated cellulose and being free of a surface finish, said web having a density within the range of from 0.05 to 0.4 grams, preferably 0.1 to 0.2 grams, per cubic centimeter, possessing improved vertical wicking properties compared to a similar web of inflated, regenerated cellulose fibers which comprise a surface finish.
Claim 2
Dependent Claim
68 words
An absorbent web of a material, said material comprising inflated cellulose fibers, said fibers being formed from regenerated cellulose and being free of a surface finish, said web having a density within the range of from 0.05 to 0.4 grams, preferably 0.1 to 0.2 grams, per cubic centimeter, possessing improved vertical wicking properties compared to a similar web of inflated, regenerated cellulose fibers which comprise a surface finish.
Claim 3
Dependent Claim
16 words
The absorbent web of Claim 1 wherein said inflated cellulose fibers are at least partially collapsed.
Claim 4
Dependent Claim
16 words
The absorbent web according to Claims 1 or 2 wherein the inflated cellulose fibers are crosslinked.

Claim 7
Dependent Claim
32 words
An absorbent web of a material, said material comprising crosslinked inflated cellulose fibers, said web possessing improved vertical wicking properties when compared to a similar web formed from non-crosslinked inflated cellulose fibers.
Claim 8
Dependent Claim
32 words
An absorbent web of a material, said material comprising crosslinked inflated cellulose fibers, said web possessing improved vertical wicking properties when compared to a similar web formed from non-crosslinked inflated cellulose fibers.
Claim 9
Dependent Claim
17 words
The absorbent web according to Claim 6 wherein the inflated cellulose fibers are formed from regenerated cellulose.
Claim 10
Dependent Claim
