Abstract
An absorbent article having improved fit and comfort. The absorbent core is designed such that fluid is moved substantially from the crotch region to the waist regions. Preferred absorbent covers have an acquisition region, a distribution region, and a storage region.
Claims17
An absorbent article for acquiring and containing fluid, the absorbent article comprising:
- a topsheet;
- a backsheet joined to said topsheet;
- and
- an absorbent core for acquiring and storing fluid deposited on the absorbent article, said absorbent core being positioned between said topsheet and said backsheet, said absorbent core comprising:
- a) an acquisition region for acquiring fluid, said acquisition region comprising an acquisition material having acquisition material having
- i) a medium desorption presure (MDP) value of at least about 5 cm but less than about 18 cm;
- and
- ii) an initial acquisition rate of at least about 5 ml/sec measured in a Curved Acquisition Test;
- and
- b) a distribution region for distributing fluid away from the area of initial deposit, said distribution region being in fluid communication with said acquisition region, said distribution region comprising a distribution material having
- i) a capillary absorption pressure of at least about 24 cm;
- ii) a vertical wicking rate to a height of 5 cm in no more than about 15 minutes;
- and
- iii) a vertical wicking absorbent capacity of at least about 5 g/g at a height of about 20 cm.
