A sanitary napkin comprising:
- a. a topsheet, a backsheet, and an absorbent core, said topsheet having a machine direction and a cross machine direction defining a MD-CD plane, said topsheet comprising a fibrous nonwoven web and a plurality of discrete tufts of fibrous material extending from said fibrous nonwoven web, wherein each said tuft has a linear orientation defining a longitudinal axis in said MD-CD plane, wherein each of said tufts comprise a plurality of looped fibers, wherein said absorbent core is between said fibrous nonwoven web and said backsheet, wherein said looped fibers have an average looped fiber diameter and said fibrous nonwoven web has an average fiber diameter, wherein said average looped fiber diameter of said looped fibers is less than said average fiber diameter of said fibrous nonwoven web;
- b. wherein said topsheet has a density of less than 0.027 under a load of 0.004 psi, and a density of less than 0.068 g/cc at a load of 0.23 psi.
The sanitary napkin of claim 2, wherein a plurality of said looped fibers in each said tuft are generally aligned with one another in said cross machine direction.
A sanitary napkin comprising a topsheet, backsheet, and absorbent core, said topsheet comprising a first precursor web and a second precursor web, one of which is a fibrous nonwoven web, wherein said topsheet further comprises discrete tufts of fibrous material that extend from said fibrous nonwoven web, wherein said tufts comprise a plurality of looped fibers, wherein said topsheet comprises two sides, wherein both sides of said topsheet are substantially covered by fibers from said fibrous nonwoven web, wherein said absorbent core is between said fibrous nonwoven web and said backsheet.
