Abstract
An absorbent product, for use in absorbent articles, comprising an absorbent layer and a wicking layer of densified hydrophilic material. The absorbent layer comprises resilient hydrophilic fibers and superabsorbent material. The absorbent layer includes at least one area comprising a bulky fibrous structure having high void regions of low fiber density randomly distributed in the structure.
Claims28
An absorbent product comprising
- an absorbent layer having upper and lower sides and comprising from about 10 to about 80% by weight of hydrophilic resilient fibers and from about 20 to about 90% by weight of superabsorbent material, said absorbent layer including at least one area comprising a prestretched bulky fibrous structure having high void regions of lower fiber density threw an unstretched region randomly distributed therein;
- said high void regions of lower fiber density formed from stretching of the fibrous structure which results in resilient fiber breakage and loosening, thereby forming less dense fiber areas in the absorbent layer;
- and
- a densified hydrophilic material placed adjacent to and at least coextensive with said at least one area of the absorbent layer to promote planar liquid transport within said absorbent layer.
A disposable diaper including an absorbent product positioned between a substantially liquid impermeable backsheet and a liquid permeable topsheet, said absorbent product comprising:
- an absorbent layer having upper and lower sides and comprising from about 10 to about 80% by weight of hydrophilic resilient fibers and from about 20 to about 90% by weight of superabsorbent material, said absorbent layer including at least one area comprising a prestretched bulky fibrous structure having high void regions of lower fiber density than an unstretched region randomly distributed therein;
- said high void regions of lower fiber density formed from stretching of the fibrous structure which results in resilient fiber breakage and loosening, thereby forming less dense fiber areas in the absorbent layer;
- and
- a densified hydrophilic material placed adjacent to and at least coextensive with said at least one area of the absorbent layer to promote planar liquid transport within said absorbent layer.
An absorbent layer comprising
- an absorbent layer having upper and lower sides and comprising from about 10 to about 80% by weight of hydrophilic resilient fibers and from about 20 to about 90% by weight of superabsorbent material, said absorbent layer including at least one area comprising a prestretched bulky fibruos structure having high void regions of lower fiber density than an unstretched region randomly distributed therein;
- said high void regions of lower fiber density formed from stretching of the fibrous structure which results in resilient fiber breakage and loosening, thereby forming less dense fiber area in the absorbent layer.
