ABSTRACT:
A breathable diaper, feminine hygiene, or like disposable sanitary product construction having a cloth-like outer surface and including a plurality of materials from the skin-facing side outwardly, a topsheet, a core, an optional barrier, and a backsheet. The topsheet is formed of liquid- and vapor-permeable hydrophilic material, and the core is formed of highly absorbent material disposed outwardly of the topsheet for absorbing liquid received through the topsheet. The core has an inner surface in liquid communication the said topsheet and an outer surface. The optional barrier is formed of a multilayer non-woven material which is hydrophobic and vapor-permeable for limiting the outward escape of liquid therethrough while enabling the outward escape of heat and water vapor therethrough. The barrier has a base disposed adjacent the core outer surface. The backsheet is formed of a multilayer non-woven material which is hydrophobic and vapor permeable for limiting the outward escape of liquid therethrough while enabling the outward escape of heat and water vapor therethrough. The backsheet is disposed at least partially as an outer surface of the diaper. At least one of the optional barrier material and the backsheet material has at least two meltblown layers.
