The present disclosure features a feminine hygiene product, including a nonwoven layer including polymeric fibers and/or filaments; a crosslinked cellulose layer including crosslinked cellulose fibers; wherein the crosslinked cellulose layer is positioned opposed to the nonwoven layer (e.g., without an intervening layer different from the crosslinked cellulose layer and the nonwoven layer; in some embodiments, the crosslinked cellulose layer is immediately adjacent to the nonwoven layer); and an interfacial region between the nonwoven layer and the crosslinked cellulose layer, the interfacial region including physically entangled polymeric fibers and/or filaments from the nonwoven layer and crosslinked cellulose fibers from the crosslinked cellulose layer. The nonwoven layer and the crosslinked cellulose layer of the composite fabric are mechanically inseparable in a dry state.

ABSORBENT ARTICLES AND METHODS OF MAKING

An absorbent article comprising an absorbent core sandwiched between a liquid permeable topsheet and a liquid impermeable back-sheet, and an acquisition distribution system positioned between said topsheet and said absorbent core, wherein the absorbent core comprises absorbent material selected from the group consisting of cellulose fibers, superabsorbent polymers and combinations thereof, wherein said absorbent material is contained within at least one core wrap substrate enclosing said absorbent material, and wherein a top layer of said core wrap is adhered to a bottom layer of said core wrap to form one or more channels substantially free of said absorbent material, wherein said channels have a length extending along a longitudinal axis and the absorbent core has a length extending along said longitudinal axis and wherein the length of said channels is from 10% to 95% of the length of said absorbent core and wherein said channels each follow a substantially continuous path such as from a first end of a channel to a second end of the same channel wherein the acquisition distribution system is multi-layered and comprises at least one spunbond layer and at least one meltblown layer, and wherein said acquisition distribution system is positioned between said absorbent core and said topsheet such that said spunbond and/or meltblown layers are in direct contact with said absorbent core and said topsheet.

ABSORBENT ARTICLES AND METHODS OF MAKING

An absorbent article comprising an absorbent core sandwiched between a liquid permeable topsheet and a liquid impermeable backsheet, and an acquisition distribution layer positioned between said topsheet and said absorbent core, wherein the absorbent core comprises absorbent material selected from the group consisting of cellulose fibers, superabsorbent polymers and combinations thereof, said absorbent core comprising at least one interconnected channel free of said absorbent material, wherein said channel has a length extending along a longitudinal axis and the absorbent core has a length extending along said longitudinal axis and wherein the length of said channel is from 10% to 95% of the length of said absorbent core wherein the acquisition distribution layer comprises a spunbond and/or carded nonwoven layer comprising synthetic fibers, wherein said synthetic fibers are comprised at a level of greater than 80% wt by weight of said acquisition distribution layer, and wherein said acquisition distribution layer has a basis weight of from 10 to 50 g/m2.

ABSORBENT ARTICLE COMPRISING FLUID HANDLING ZONES

An absorbent article comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet. The absorbent article comprises a first fluid handling zone having a first Transverse Fluid Travel Distance and a second fluid handling zone having a second Transverse Fluid Travel Distance. The first Transverse Fluid Travel Distance is at least about 50% greater than said second Transverse Fluid Travel Distance, which results in an absorbent article that is better able to handle bodily fluids and reduce the risk of accidental leakage of bodily fluids onto a consumer's undergarments.

Absorbent article and absorbent core forming channels when wet

An absorbent article for personal hygiene comprising a liquid permeable topsheet, a liquid impermeable backsheet, an absorbent core and a fibrous layer. The absorbent core comprises a core wrap and an absorbent material with superabsorbent polymers. The core wrap comprises a top side and a bottom side bonded to one other through one or more areas substantially free of absorbent material. The fibrous layer is at least partially bonded to one of the sides of the core wrap in the area substantially free of absorbent material. When the absorbent material swells, the core wrap forms one or more channels along the area substantially free of absorbent material. The formation of the channel in the absorbent core causes the formation of one or more corresponding ditches in the fibrous layer.

A liquid permeable surface sheet (3) includes an upper layer non-woven fabric (20) which is provided at the skin side, and which is hydrophilic, and a lower layer non-woven fabric (21) which is provided at the non-skin side, and which is water repellent. Multiple apertures (22) are formed which penetrate the upper layer non-woven fabric and the lower layer non-woven fabric. Accordingly, body fluid transfers smoothly through the apertures to an absorbent body. The upper layer non-woven fabric at the skin side is made to be hydrophilic such that body fluid readily permeates therethrough. The lower layer non-woven fabric at the non-skin side is made to be water repellent such that the body fluid which has passed through is not readily absorbed again. Accordingly, the backflow amount of body fluid can be reduced.
