Abstract
An absorbent article includes a liquid pervious topsheet, a backsheet at least peripherally joined to the topsheet, and an absorbent core disposed between said topsheet and said backsheet. The absorbent article further includes an integrated nonwoven fluid management layer having a basis weight between about 40 gsm and about 65 gsm; and an Urine Standard Rewet Value of 10 mg or less.
Claims15
An absorbent article comprising:
- a liquid pervious topsheet, wherein the topsheet comprises a nonwoven, wherein the nonwoven is a through-air bonded nonwoven having a plurality of apertures and a plurality of recessions, wherein the nonwoven comprises hydrophobic fibers and hydrophilic fibers, and wherein the nonwoven comprises at least 50% hydrophilic fibers;
- a backsheet at least peripherally joined to the topsheet;
- an absorbent core disposed between said topsheet and said backsheet;
- an integrated nonwoven fluid management layer having a basis weight between about 40 gsm and about 65 gsm and a caliper factor of greater than 0.2 mm to about 0.3 mm, and wherein the fluid management layer comprises absorbent fibers and stiffening fibers and the ratio of the absorbent fibers to the stiffening fibers is from about 1:7 to about 2:1;
- and
- a Urine Standard Rewet Value of 10 mg or less.
3 more elements
A liner comprising:
- a liquid pervious topsheet, wherein the topsheet comprises a nonwoven, wherein the nonwoven comprises hydrophobic fibers and hydrophilic fibers, wherein the nonwoven comprises at least 50% hydrophilic fibers, and wherein the topsheet is void of film;
- a backsheet at least peripherally joined to the topsheet;
- an absorbent core disposed between said topsheet and said backsheet;
- a longitudinal centerline and a transverse centerline;
- an integrated nonwoven fluid management layer having a caliper factor of greater than 0.2 mm to about 0.3 mm, and wherein the fluid management layer comprises absorbent fibers and stiffening fibers and the ratio of the absorbent fibers to the stiffening fibers is from about 1:7 to about 2:1;
- wherein the liner comprises an increasing porosity gradient in a first z direction, wherein the first z direction extends from the backsheet towards the topsheet;
- and
- a Urine Standard Rewet Value of 10 mg or less,
- wherein the topsheet is from about 5% to about 20% greater in porosity than the fluid management layer.
6 more elements
A liner comprising:
- a liquid pervious topsheet, wherein the topsheet comprises a nonwoven, wherein the nonwoven comprises hydrophobic fibers and hydrophilic fibers, wherein the nonwoven comprises at least 50% hydrophilic fibers, wherein the nonwoven comprises a plurality of macro deformations, wherein the plurality of macro deformations comprise a major axis that is greater than about 0.5 mm and less than about 2.0 mm and a minor axis that is greater than 0.4 mm and less than about 1.5 mm, and wherein the topsheet is void of film;
- a backsheet at least peripherally joined to the topsheet;
- an absorbent core disposed between said topsheet and said backsheet, wherein the absorbent core comprises an airlaid core with a basis weight of at least 150 gsm;
- and
- an integrated nonwoven fluid management layer having a basis weight between about 40 gsm and about 65 gsm and a caliper factor of greater than 0.2 mm to about 0.3 mm, and wherein the fluid management layer comprises absorbent fibers and stiffening fibers and the ratio of the absorbent fibers to the stiffening fibers is from about 1:7 to about 2:1;
- wherein the liner comprises a Wet CD Bunch Compression of at least 325 gf.
