摘要:
An absorbent article having a stretchable substrate and an absorbent composite comprising a layer of adhesive composition in contact with the stretchable substrate. A layer of particulate superabsorbent material is applied to and held by the adhesive composition. The absorbent composite is secured to the substrate by the adhesive composition. The stretchable substrate has a recovery in at least one of the lateral direction and the longitudinal directions of the article as determined by an Elongation and Recovery Test, and the absorbent article has a recovery in the at least one of the lateral direction and the longitudinal direction as determined by the Elongation and Recovery Test that is at least about 60 percent of the recovery of the substrate in the at least one of the lateral direction and the longitudinal direction.
摘要:
An absorbent article is provided for absorbing a liquid, the absorbent article including a chassis including a liner, an outer cover, and an absorbent structure positioned between the liner and the outer cover, the chassis including a front region and a back region, the front region and the back region defining a waist region therebetween. The absorbent article also includes a wetness indicator positioned adjacent the liner or the outer cover, the wetness indicator including a hydrophanous tissue layer having an absorbent-structure-facing side and being in liquid communication with the absorbent structure or the liner, and an indicator material disposed between the absorbent-facing side of the tissue layer and the absorbent structure. The absorbent article can also include a film layer disposed adjacent the tissue layer, and the indicator material can include an active constituent adapted to wick along the tissue layer when the absorbent article is insulted.
摘要:
Disclosed is an absorbent article including a stretchable, liquid impermeable outercover, a stretchable, liquid permeable liner generally superposed with the outercover and an absorbent structure disposed between the liner and the outercover. The absorbent structure includes an absorbent body including at least two segments.
摘要:
A chemical gas sensor formed from a nonwoven material is described. The gas sensor includes a flexible, gas-permeable, nonwoven web-based material substrate having a matrix that is composed of a plurality of inert thermoplastic, pulp, cellulose or staple fibers as either a major or minor portion, with a plurality of gas-sensitive fibers formed from a polymer that can absorb volatile organic compounds (VOC), and a plurality of electrically conductive fibers. The gas-sensitive fibers are intermixed with and associated spatially among a network of adjacent electrically conductive fibers, such that a change in physical morphology of said gas-sensitive fibers as a result of interacting with volatile organic compounds, causes a change in dielectric properties that disrupts said network of adjacent electrically conductive fibers. The sensor can be configured as either a resistive or a capacitive chemisensor.
摘要:
A method of making stretchable absorbent articles includes the steps of providing a continuous substrate layer, providing one or more streams of adhesive fibers and superabsorbent particles, shaping the one or more streams of adhesive fibers and superabsorbent particles, depositing the adhesive fibers and superabsorbent particles on the substrate layer to form a plurality of shaped absorbent cores bound to the substrate layer, and separating the absorbent cores from each other. The absorbent cores thus formed do not prevent stretching of the substrate layer. The combination of absorbent core and substrate layer can be used in a wide variety of personal care absorbent articles and medical absorbent articles.
摘要:
The present subject matter relates to absorbent articles and signaling devices for use therewith. The signaling device can be configured to detect the presence of an insult in the absorbent article and/or in an undergarment. The signaling device can be further configured to determine whether the insult is a urine insult or a feces insult. The signaling device can provide a notification to a user that an insult has occurred and can inform the user whether the insult is a urine insult or a feces insult.
