Abstract
A disposable diaper has a moisture impermeable backing sheet, a fibrous absorbent batt and a flexible hydrophobic facing sheet overlying the batt, the components being secured together to form a sandwich structure; the facing sheet has an aperture in the central crotch region of the diaper with zones of elastication in the facing sheet tending to apply tensioning forces to the facing sheet for urging the facing sheet (at least in the regions adjacent the aperture) away from the underlying batt structure. With advantage the facing sheet is a breathable web of bonded fibres highly resistant to permeation of moisture. It is preferred that the absorbent batt structure comprises a wood-pulp batt and a non-woven sheet of moisture permeable material overlying the absorbent batt.
