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.
Claims32
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 about 0.05 to about 0.4 grams per cubic centimeter, possessing improved vertical wicking properties compared to a similar web of inflated, regenerated cellulose fibers which comprise a surface finish.
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.
An absorbent product, said product comprising a web of an absorbent material, said web comprising inflated cellulose fibers, said fibers being formed from regenerated cellulose and being free of a surface finish, said web possessing improved vertical wicking properties when compared to a similar web formed from inflated, regenerated cellulose fibers which comprise a surface finish.
An absorbent product, said product comprising a web of an absorbent material, said web 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.
