摘要： A breathable diaper, feminine hygiene, or like disposable sanitary product construction includes a plurality of materials including, from the skin-facing side outwardly, a topsheet of liquid- and vapor-permeable hydrophilic material. A core of highly absorbent material is disposed outwardly of the topsheet for absorbing fluid received through the topsheet, the core having an inner surface in fluid communication with the topsheet. A backsheet is disposed at least partially as an outer surface of the construction and is formed of a pouch defined by two layers of a non-woven hydrophobic and vapor-permeable material, with absorbent or superabsorbent particles therebetween, so that the backsheet limits the outward escape of liquid therethrough while enabling the outward escape of heat and water vapor therethrough. Each backsheet layer is an at least two-layer spunbound-meltblown SM or an at least three-layer spunbond-meltblown-spunbond SMS.

摘要： A composite includes a first substrate, a second substrate, and a discontinuous adhesive structure disposed intermediate the first and second substrates for securing the first and second substrates together to form a composite without significantly modifying the properties of either of the first and second substrates. The discontinuous adhesive structure is an array of substantially linear filaments or strands of an adhesive.

摘要： A breathable diaper, feminine hygiene, or like disposable sanitary product construction includes a plurality of materials comprising, from the skin-facing side outwardly a topsheet of liquid- and vapor-permeable hydrophilic material. A core of highly absorbent material disposed outwardly of the topsheet for absorbing fluid received through said topsheet. The core has an inner surface in fluid communication with the topsheet, an outer surface and two lateral side surfaces. A barrier is formed of a multilayer non-woven material which is hydrophobic and vapor-permeable for limiting the outward escape of fluid therethrough while enabling the outward escape of heat and water vapor therethrough, such as a two-layer spunbond-meltblown or a three-layer spunbond-meltblown-spunbond. In use, the barrier is in a U-shaped configuration having a base disposed adjacent the core outer surface and a pair of flanges upstanding from the base and each extending inwardly adjacent to a respective one of the core lateral side surfaces. A backsheet is formed of a multilayer non-woven material which is hydrophobic and vapor-permeable for limiting the outward escape of fluid therethrough while enabling the outward escape of heat and water vapor therethrough, such as a two-layer spunbond-meltblown or a three-layer spunbond-meltblown-spunbond. The backsheet is disposed at least partially outwardly of the barrier base.
