Abstract:
A sanitary napkin is disclosed as a form of disposable absorbent article. It has an absorbent core and a hydrophobic topsheet that has an upper side that is to be worn against a user's body. The topsheet is selected from a group of nonwoven topsheets and apertured film topsheets. A trace amount of a fibrous superabsorbent material, in the range of 0.30 and 3.5 grams of superabsorbent material per square meter, is provided in a fibrous matrix in a secondary topsheet that is in intimate contact with the lower side of the topsheet. The fibrous matrix is made by airlaying the superabsorbent material with cellulose and bi-component fiber onto a non-woven carrier.
