Abstract

A fluid distribution material for use in an absorbent article includes a formed film layer having a user-facing side and a garment-facing side opposite the user-facing side. The formed film layer includes a plurality of apertured protuberances arranged in a pattern having 10 to 40 protuberances per linear inch. Each of the protuberances includes a continuous sidewall extending from the user-facing side. The garment-facing side has a plurality of apertures aligned with the plurality of apertured protuberances and land areas in between the apertures. A nonwoven layer is laminated to the garment-facing side of the formed film layer. The nonwoven layer includes a plurality of continuous fibers extending across the land areas and the plurality of apertures of the formed film layer and attached to the land areas at bond sites. The fluid distribution material has a compressibility of less than 10% between pressures of 0.21 psi and 0.60 psi.

Claims (35)

1. A fluid distribution material for use in an absorbent article, the fluid distribution material comprising:

a formed film layer having a user-facing side and a garment-facing side opposite the user-facing side, the formed film layer comprising a plurality of apertured protuberances arranged in a pattern having 10 to 40 protuberances per linear inch, each of the protuberances comprising a continuous sidewall extending from the user-facing side, the garment-facing side having a plurality of apertures aligned with the plurality of apertured protuberances and land areas in between the apertures; and

a nonwoven layer laminated to the garment-facing side of the formed film layer, the nonwoven layer comprising a plurality of continuous fibers extending across the land areas and the plurality of apertures of the formed film layer and attached to the land areas at bond sites,

wherein the fluid distribution material has a compressibility of less than 10% between pressures of 0.21 psi and 0.60 psi, and

wherein the plurality of continuous fibers of the nonwoven layer are embedded into the land areas of the formed film layer at the bond sites.

2. The fluid distribution material according to claim 1 , wherein the formed film layer has a basis weight of between about 10 gsm and about 25 gsm.

3. The fluid distribution material according to claim 1 , wherein the nonwoven layer has a basis weight of between about 10 gsm and about 15 gsm.

4. The fluid distribution material according to claim 1 , wherein the nonwoven layer comprises a spunbond nonwoven.

5. A fluid management system for use in an absorbent article, the fluid management system comprising:

a fluid distribution material comprising

a formed film layer having a user-facing side and a garment-facing side opposite the user-facing side, the formed film layer comprising a plurality of apertured protuberances arranged in a pattern having 10 to 40 protuberances per linear inch, each of the protuberances comprising a continuous sidewall extending from the user-facing side, the garment-facing side having a plurality of apertures aligned with the plurality of apertured protuberances and land areas in between the apertures; and

a nonwoven layer laminated to the garment-facing side of the formed film layer, the nonwoven layer comprising a plurality of continuous fibers extending across the land areas and the plurality of apertures of the formed film layer and attached to the land areas at bond sites,

wherein the fluid distribution material has a compressibility of less than 10% between pressures of 0.21 psi and 0.60 psi, and

wherein the plurality of continuous fibers of the nonwoven layer are embedded into the land areas of the formed film layer at the bond sites; and

a topsheet attached to the fluid distribution material, wherein the user-facing side of the formed film layer faces the topsheet.

6. The fluid management system according to claim 5 , wherein the formed film layer has a basis weight of between about 10 gsm and about 25 gsm.

7. The fluid management system according to claim 5 , wherein the nonwoven layer has a basis weight of between about 10 gsm and about 15 gsm.

8. The fluid management system according to claim 5 , wherein the topsheet comprises an apertured formed film.

9. The fluid management system according to claim 5 , wherein the topsheet comprises a nonwoven web.

10. The fluid management system according to claim 5 , wherein the topsheet comprises a laminate.

11. An absorbent article comprising:

a fluid distribution material, the fluid distribution material comprising

a formed film layer having a user-facing side and a garment-facing side opposite the user-facing side, the formed film layer comprising a plurality of apertured protuberances arranged in a pattern having 10 to 40 protuberances per linear inch, each of the protuberances comprising a continuous sidewall extending from the user-facing side, the garment-facing side having a plurality of apertures aligned with the plurality of apertured protuberances and land areas in between the apertures; and

a nonwoven layer laminated to the garment-facing side of the formed film layer, the nonwoven layer comprising a plurality of continuous fibers extending across the land areas and the plurality of apertures of the formed film layer and attached to the land areas at bond sites,

wherein the fluid distribution material has a compressibility of less than 10% between pressures of 0.21 psi and 0.60 psi, and

wherein the plurality of continuous fibers of the nonwoven layer are embedded into the land areas of the formed film layer at the bond sites;

a backsheet; and

an absorbent material in between the fluid distribution material and the backsheet.

12. The absorbent article according to claim 11 , wherein the formed film layer has a basis weight of between about 10 gsm and about 25 gsm.

13. The absorbent article according to claim 11 , wherein the nonwoven layer has a basis weight of between about 10 gsm and about 15 gsm.

14. The absorbent article according to claim 11 , further comprising a topsheet,

wherein the fluid distribution material is disposed between topsheet and the absorbent core.

15. The absorbent article according to claim 14 , wherein the topsheet comprises an apertured formed film.

16. The absorbent article according to claim 14 , wherein the topsheet comprises a nonwoven web.

17. The absorbent article according to claim 14 , wherein the topsheet comprises a laminate.
