ABSTRACT OF THE DISCLOSURE A paper diaper comprises, from the top downwards, a fluff pulp surface layer or ply, a holed or grooved partition layer, a diffusion crust layer, and a fluff pulp main layer or ply, all wrapped up in a non-woven fabric. When the diaper is worn, fluid discharged is absorbed in a somewhat localized area, passes downwards through this area, and then falls down through the partition layer onto the crust layer which diffuses the fluid throughout substantially the whole area of the diaper and also retains some. Thus, the whole of the diaper is slightly moistened but does not cause any dis- comfort such as a drippingly wet feeling. Flowing back of the fluid from the crust layer to the surface layer is prevented by the partition layer.
