发明名称 AN ABSORBENT CORE HAVING A DENSITY GRADIENT
摘要 In a sanitary napkin (10), the retention layer (34) of the absorbent core is covered by a first tissue sheet of a density between 0.01 g/cm3 and 0.1 g/cm3 and by a second tissue sheet of a density between 0.08 and 0.3 g/cm3, the difference in density between the tissue sheets being between 0.01 g/cm3 and 0.2 g/cm3. The density gradient on top of the retention layer (34) results in a relatively high efficiency of the retention layer (34) and in efficient draining of the topmost tissue sheet, so that chances of rewet are reduced.
