Abstract

An absorbent article having improved handling of body exudates. The absorbent article can minimize the amount of body exudates in contact with a wearer's skin and can minimize the incidence of leakage of body exudates from the absorbent article.

Claims (42)

1 . An absorbent article comprising:

a. a fluid-entangled body facing material comprising:

i. a support layer comprising opposed first and second surfaces;

ii. a projection layer comprising a plurality of fibers and opposed inner and outer surfaces, the second surface of the support layer in contact with the inner surface of the projection layer; and

iii. a plurality of hollow projections formed from a first plurality of the plurality of fibers in the projection layer, the plurality of hollow projections extending from the outer surface of the projection layer in a direction away from the support layer;

b. an outer cover; and

c. an absorbent body positioned between the fluid-entangled body facing material and the outer cover;

wherein the second intake time of simulated menses through the fluid-entangled body facing material is less than about 30 seconds following insult with simulated menses according to the test method described herein.

2 . The absorbent article of claim 1 wherein a second plurality of fibers of the plurality of fibers in the projection layer are entangled with the support layer.

3 . The absorbent article of claim 1 wherein the second intake time of simulated menses through the fluid-entangled body facing material is less than about 20 seconds following insult with simulated menses according to the test method described herein.

4 . The absorbent article of claim 3 wherein the second intake time of simulated menses through the fluid-entangled body facing material is less than about 15 seconds following insult with simulated menses according to the test method described herein.

5 . The absorbent article of claim 1 wherein the absorbent body is free of superabsorbent material.

6 . The absorbent article of claim 1 wherein the absorbent body comprises greater than about 15% superabsorbent material.

7 . The absorbent article of claim 1 wherein the fluid-entangled body facing material comprises a load of more than about 2 Newtons per 25 mm width at 10% extension in the machine direction.

8 . The absorbent article of claim 1 wherein the projections have a height greater than about 1 mm.

9 . The absorbent article of claim 1 further comprising a secondary liner positioned between the fluid-entangled body facing material and the absorbent body.

10 . The absorbent article of claim 1 wherein the fluid-entangled body facing material further comprises a land area which can have greater than about 1% open area in a chosen area of the fluid-entangled body facing material.

11 . The absorbent article of claim 10 wherein the open area is due to interstitial fiber-to-fiber spacing.

12 . The absorbent article of claim 1 wherein the projections have less than about 1% open area in a chosen area of the fluid-entangled body facing material.

13 . The absorbent article of claim 1 wherein the fluid-entangled body facing material comprises a resiliency of greater than about 70%.

14 . The absorbent article of claim 1 wherein the absorbent article is a feminine hygiene product.

15 . An absorbent article comprising:

a. a fluid-entangled body facing material comprising:

i. a support layer comprising opposed first and second surfaces;

ii. a projection layer comprising a plurality of fibers and opposed inner and outer surfaces, the second surface of the support layer in contact with the inner surface of the projection layer; and

iii. a plurality of hollow projections formed form a first plurality of the plurality of fibers in the projection layer, the plurality of hollow projections extending from the outer surface of the projection layer in a direction away from the support layer;

b. an outer cover;

c. an absorbent body positioned between the fluid-entangled body facing material and the outer cover; and

d. a secondary liner positioned between the fluid-entangled body facing material and the absorbent body;

wherein the second intake time of simulated menses through the fluid-entangled body facing material is less than about 30 seconds following insult with simulated menses according to the test method described herein.

16 . The absorbent article of claim 15 wherein a second plurality of fibers of the plurality of fibers in the projection layer are entangled with the support layer.

17 . The absorbent article of claim 15 wherein the second intake time of simulated menses through the fluid-entangled body facing material is less than about 20 seconds following insult with simulated menses according to the test method described herein.

18 . The absorbent article of claim 17 wherein the second intake time of simulated menses through the fluid-entangled body facing material is less than about 15 seconds following insult with simulated menses according to the test method described herein.

19 . The absorbent article of claim 15 wherein the absorbent body is free of superabsorbent material.

20 . The absorbent article of claim 15 wherein the absorbent body comprises greater than about 15% superabsorbent material.

21 . The absorbent article of claim 15 wherein the fluid-entangled body facing material comprises a load of more than about 2 Newtons per 25 mm width at 10% extension in the machine direction.

22 . The absorbent article of claim 15 wherein the projections have a height greater than about 1 mm.

23 . The absorbent article of claim 15 wherein the fluid-entangled body facing material further comprises a land area which can have greater than about 1% open area in a chosen area of the fluid-entangled body facing material.

24 . The absorbent article of claim 23 wherein the open area is due to interstitial fiber-to-fiber spacing.

25 . The absorbent article of claim 15 wherein the projections have less than about 1% open area in a chosen area of the fluid-entangled body facing material.

26 . The absorbent article of claim 15 wherein the fluid-entangled body facing material further comprises a resiliency of greater than about 70%.

27 . The absorbent article of claim 15 wherein the absorbent article is a feminine hygiene product.
