Abstract

Disposable absorbent articles having a fluid intake pledget. Disposable absorbent articles such as feminine hygiene products (e.g., sanitary napkins and panti-liners) and incontinence products having an airlaid, lofty pledget of a low density, nonwoven material for intake of body fluids.

Claims

1. An absorbent article, comprising an absorbent core and an intake intensifier pledget located on a central portion of the absorbent core, the pledget further comprising a material selected from the group consisting of an airlaid nonwoven material, a TABCW material, a composite of a fiber material and an airlaid material, and combinations of a fiber layer and an airlaid layer.

2. The absorbent article of

claim 1

, wherein the composite has a first layer and a second layer, and wherein the first layer comprises a fiber material and the second layer comprises an airlaid material.

3. The absorbent article of

claim 1

, wherein the airlaid nonwoven material has a basis weight of between about 50 and about 300 gsm, said basis providing for high void volume.

4. The absorbent article of

claim 1

, wherein the airlaid nonwoven material includes a superabsorbent material.

5. The absorbent article of

claim 1

, wherein the TABCW material provides a low densified lofty thru-air bonded carded web and has a basis weight of between about 15 and about 70 gsm.

6. The absorbent article of

claim 5

, wherein the TABCW material comprises a staple fiber having a denier of between about 3 and about 10.

7. The absorbent article of

claim 5

, wherein the TABCW material comprises an Ultra Bulky (UB) bicomponent fiber or composites thereof.

8. The absorbent article of

claim 1

, wherein the pledget further comprises a first layer and a second layer, the first layer comprising a TABCW material and the second layer comprising an airlaid nonwoven material.

9. The absorbent article of

claim 1

, wherein the pledget comprises a composite of an airlaid nonwoven material and a TABCW.

10. The absorbent article of

claim 1

, wherein the absorbent core comprises a material selected from the group consisting of a composite of superabsorbent material and pulp, a tissue, a non-woven material and a mixture of fluff and a superabsorbent material.

11. The absorbent article of

claim 1

, wherein the pledget has a length of at least about 50 mm and a width of from about 30 to about 60 mm.

12. The absorbent article of

claim 1

, comprising a cover, a wrapping material, and a baffle, wherein the pledget has a first surface situated adjacent the garment-facing surface of the cover and a second surface bonded to at least one of the absorbent core or the wrapping material.

13. The absorbent article of

claim 12

, further comprising a fluid distribution layer.

14. The absorbent article of

claim 13

, further comprising an embossed channel having a width of less than about 1 cm and situated adjacent the periphery of the pledget.

15. An absorbent article, comprising a cover, an absorbent core and an intake intensifier pledget located on a central portion of the absorbent core, wherein the cover further comprises a hydroentangled, hydroapertured spun-lace material and the pledget further comprises a TABCW material.

16. The absorbent article of

claim 15

, wherein the hydroentangled, hydroapertured spun-lace material is rayon fiber.

17. The absorbent article of

claim 15

, wherein the hydroentangled, hydroapertured spun-lace material is selected from the group consisting of PET polyester, polyethylene, polypropylene and bicomponents thereof.

18. The absorbent article of

claim 15

, wherein the hydroentangled, hydroapertured spun-lace material is a homogeneous mixture of about 70% rayon fiber and about 30% PET polyester.

19. An absorbent article, comprising a cover, a first absorbent layer and a second absorbent layer, the first absorbent layer being situated between the cover and the second absorbent layer, the cover further comprising a hydroentangled, hydroapertured spun-lace material, the first absorbent layer further comprising a material selected from the group consisting of an airlaid material, a TABCW material and a composite material of a fiber layer and an airlaid layer, and the second absorbent layer further comprising a material selected from the group consisting of an airlaid material, a TABCW material and a composite material of a fiber layer and an airlaid layer.

20. The absorbent article of

claim 19

, wherein the hydroentangled, hydroapertured spun-lace material is rayon fiber.

21. The absorbent article of

claim 19

, wherein the hydroentangled, hydroapertured spun-lace material is selected from the group consisting of PET polyester, polyethylene, polypropylene and bicomponents thereof.

22. The absorbent article of

claim 19

, wherein said a hydroentangled, hydroapertured spun-lace material is a homogeneous mixture of about 70% rayon fiber and about 30% PET polyester.
