Abstract
A disposable absorbent article having a topsheet, a backsheet, an absorbent core disposed between the topsheet and the backsheet, and a fluid management layer disposed between the topsheet and the absorbent core is disclosed. The disposable absorbent article provides improved fluid acquisition, improved stain size control, and improved performance when wet.
Claims20
A disposable absorbent article comprising:
- a topsheet;
- a backsheet;
- an absorbent core disposed between the topsheet and the backsheet;
- an integrated nonwoven fluid management layer disposed between the topsheet and the absorbent core,
- wherein the fluid management layer comprises a basis weight in a range of from 40 gsm to 75 gsm as determined by the Basis Weight method,
- wherein the fluid management layer has a caliper of greater than 0.2 mm per 10 gsm, wherein the fluid management layer comprises:
- from between about 20 percent to 40 percent by weight of absorbent fibers,
- from between about 25 percent to 50 percent of resilient fibers, and
- from between about 30 percent to 60 percent stiffening fibers, as determined by the Material Composition Analysis,
- wherein the stiffening fibers comprise bi-component fibers, and wherein at least a portion of the bi-component fibers are heat treated forming a plurality of bonds between the bi-component fibers,
- wherein a ratio of absorbent fibers to stiffening fibers is from about 1:4 to about 1.5:1 and a ratio of absorbent fibers to resilient fibers is from about 1:2 to about 2:1, and
- wherein the absorbent article exhibits an average acquisition speed in a first gush of between about 5 seconds to about 13 seconds, when measured in accordance with the Repetitive Acquisition and Rewet method disclosed herein.
