Abstract
An absorbent article such as a disposable diaper or sanitary article has an absorbing core and an outer porous cover sheet to allow transfer of liquids through the cover sheet and into the core. A liquid transfer sheet in the form of a nonwoven fabric is located between the cover sheet and the core. The transfer sheet has at least two layers, with the layer facing the cover sheet having relatively coarse fibers, and the layer facing the core having relative fine fibers. The arrangement allows more efficient transfer of liquids to the core while minimizing wetback.
