Abstract

A sanitary napkin comprising a topsheet having a body-facing side and comprising a plurality of discrete tufts of fibrous material. The topsheet has a lotion composition applied to at least a portion of the body-facing side thereof. An absorbent core is in fluid communication with the topsheet, the absorbent core having an average thickness of less than about 10 mm, and a free absorbent capacity of from about 4 to about 125 grams per gram.

Claims (33)

1. A sanitary napkin comprising:

a topsheet having a body-facing side and comprising a plurality of discrete tufts of fibrous material,

a backsheet joined to said topsheet,

a lotion composition applied to at least a portion of said body-facing side of said topsheet,

an absorbent core in fluid communication with said topsheet, said absorbent core having an average thickness of less than about 10 mm, and a free absorbent capacity of from about 4 to about 125 grams per gram;

wherein said topsheet comprises a first precursor web and a second precursor web, wherein said first precursor web comprises a nonwoven web, wherein said second precursor web comprises a nonwoven web, wherein said tufts comprise fibers of said first precursor web and extend from said first precursor web through said second precursor web, wherein said absorbent core is between said first precursor web and said backsheet.

2. The sanitary napkin of claim 1 , wherein said discrete tufts comprise fibers of said first precursor web and said second precursor web.

3. The sanitary napkin of claim 1 , wherein said tufts of material comprise a plurality of looped fibers.

4. The sanitary napkin of claim 3 , wherein said looped fibers are disposed such that said discrete tufts have a distinct linear orientation and a longitudinal axis.

5. The sanitary napkin of claim 1 , wherein said topsheet has a second side, wherein said body-facing side and said second side of said topsheet are substantially covered by fibers from only one of said precursor webs.

6. The sanitary napkin of claim 5 , wherein one side of said topsheet comprises discrete tufts and the other side comprises discontinuities characterized by a generally linear indentation.

7. The sanitary napkin of claim 1 , wherein said lotion is hydrophobic.

8. The sanitary napkin of claim 1 , wherein said lotion is applied on lateral side areas of said sanitary napkin.

9. The sanitary napkin of claim 1 , wherein said absorbent core comprises high internal phase emulsion foam.

10. The sanitary napkin of claim 1 , wherein said topsheet comprises from 1 to 100 said discrete tufts per square centimeter.

11. The sanitary napkin of claim 1 , wherein said topsheet comprises from 20 to 40 said discrete tufts per square centimeter.

12. The sanitary napkin of claim 1 , wherein said lotion comprises petrolatum.

13. A sanitary napkin comprising:

a topsheet having a body-facing side and comprising from 10 to 50 discrete tufts of fibrous material per square centimeter,

a backsheet joined to said topsheet,

a semi-solid lotion composition applied to at least a portion of said body-facing side of said topsheet, and

an absorbent core in fluid communication with said topsheet, said absorbent core being a high internal phase emulsion foam and having an average thickness of less than about 10 mm;

wherein said topsheet comprises a first precursor web and a second precursor web, wherein said first precursor web comprises a nonwoven web, wherein said second precursor web comprises a nonwoven web, wherein said tufts comprise fibers of said first precursor web and extend from said from said first precursor web through said second precursor web, wherein said absorbent core is between said first precursor web and said backsheet.

14. The sanitary napkin of claim 13 , wherein said lotion comprises petrolatum.

15. The sanitary napkin of claim 13 , wherein said topsheet comprises a first precursor web and a second precursor web, wherein at least one of said precursor webs is relatively more hydrophobic with respect to said other of said precursor webs.

16. A sanitary napkin comprising:

a topsheet comprising a nonwoven first precursor web and a nonwoven second precursor web, wherein at least one of said precursor webs is relatively more hydrophobic with respect to said other of said precursor webs, and wherein said topsheet further comprises discrete tufts of fibrous material from said first or second precursor webs,

a semi-solid hydrophobic lotion composition comprising petrolatum disposed on at least a portion of said topsheet,

an absorbent core in fluid communication with said topsheet, said absorbent core having an average thickness of less than about 7 mm, and

a backsheet joined to said topsheet;

wherein said absorbent core is disposed between said topsheet and said backsheet.

17. The sanitary napkin of claim 1 , wherein said topsheet has a second side, wherein said body-facing side and said second side of said topsheet are substantially covered by fibers from said first precursor web.

18. The sanitary napkin of claim 1 , wherein said tufts are tunnel shaped.
