Absorbent Article
An absorbent article having improved handling of body exudates. The absorbent article can minimize the amount of body exudates in contact with a wearer's skin and can minimize the incidence of leakage of body exudates from the absorbent article.
ABSORBENT ARTICLES HAVING A THREE-DIMENSIONAL MATERIAL ON THE WEARER-FACING SIDE
An absorbent article includes a three-dimensional material on the wearer-facing side and an absorbent core with a material-free channel. The three-dimensional material comprises a fibrous support layer, a fibrous projection layer and a plurality of hollow projections formed from a first plurality of fibers in the projection layer.
ABSORBENT ARTICLE COMPRISING A THREE-DIMENSIONAL SUBSTRATE
An absorbent article for personal hygiene comprises a three-dimensional substrate, a tissue layer, an absorbent core and a backsheet. The absorbent core is located at least partially between the three-dimensional substrate and the backsheet. The tissue layer is located at least partially between the three-dimensional substrate and the absorbent core. The tissue layer comprises a wet-laid three-dimensional fibrous substrate comprising at least 80% pulp fibers by weight of the wet-laid three-dimensional fibrous substrate. The wet-laid three-dimensional fibrous substrate comprises a continuous network region and a plurality of discrete zones.
Three-dimensional nonwoven materials and methods of manufacturing thereof
Three dimensional nonwoven materials and absorbent articles comprising such materials are disclosed. In one embodiment, an absorbent article may comprise an outer cover, a bodyside liner, an absorbent body, and a nonwoven material coupled to the bodyside liner. The nonwoven material may comprise an apertured zone providing a percent open area for the apertured zone that is greater than about 15%. The nonwoven material may be coupled to liner by a front waist bond forming a front waist bonding region which extends through the apertured zone and a rear waist bond forming a rear waist bonding region, wherein the rear waist bonding region has a length that is between about 2% and about 10% of the material length and the front waist bonding region has a length that is between about 20% and about 50% of the material length.
Three-dimensional nonwoven materials and methods of manufacturing thereof
Three dimensional nonwoven materials and methods of manufacturing such materials are disclosed. In one embodiment, a nonwoven material may comprise a plurality of fibers, a first surface, and an apertured zone comprising: a plurality of nodes extending away from a base plane on the first surface, a plurality of connecting ligaments interconnecting the plurality of nodes, wherein a majority of the plurality of nodes include at least three connecting ligaments connecting to adjacent nodes, and a plurality of openings. The apertured zone may further comprise a lane of nodes which extends substantially in the longitudinal direction, and wherein the lane of nodes extending substantially in the longitudinal direction is formed of longitudinally adjacent nodes which are aligned such that lines drawn between centers of longitudinally adjacent nodes within the lane of nodes each form an angle with respect to the longitudinal direction of less than about 20 degrees.
Apertured formed film with a pattern of apertures and a plurality of light trap micro-pits
An apertured film with a reduced gloss through the use of light trap micro-pits uniformly distributed on the lands of the film in a random pattern and a method of making the same.
THREE-DIMENSIONAL NONWOVEN MATERIALS AND METHODS OF MANUFACTURING THEREOF
Three dimensional nonwoven materials and methods of manufacturing such materials are disclosed. In one embodiment, a nonwoven material may comprise a plurality of fibers and may further comprise an opposing first surface and a second surface, an apertured zone comprising a plurality of nodes extending away from a base plane on the first surface, a plurality of connecting ligaments interconnecting the plurality of nodes, and a plurality of openings providing a percent open area for the apertured zone that is greater than about 15%, as determined by the Material Sample Analysis Test Method. The material may further comprise a first and second side zones with the nonwoven material having a material width and the first and second side zones having first and second side zone widths, and wherein each of the first and second side zone widths are between about 5% and about 25% of the nonwoven material width.
Three-dimensional nonwoven materials and methods of manufacturing thereof
Three dimensional nonwoven materials and methods of manufacturing such materials are disclosed. In one embodiment, a nonwoven material comprising a plurality of fibers may comprise a first surface and a second surface, the first surface being opposite from the second surface, and an apertured zone. The apertured zone may comprise a plurality of nodes extending away from a base plane on the first surface, a plurality of connecting ligaments interconnecting the plurality of nodes, wherein a majority of the plurality of nodes include at least three connecting ligaments connecting to adjacent nodes, and a plurality of openings providing a percent open area for the apertured zone of the nonwoven material from about 10% to about 60%, as determined by the Material Sample Analysis Test Method.
Laminate webs and absorbent articles having the same
A laminate web having a polymer film layer and a nonwoven layer is disclosed. The polymer film layer makes up a first side of the laminate web and the nonwoven layer makes up a second side of the laminate web. The laminate web has a plurality of first elements extending from the polymer film. The web also has a plurality of second elements such as recesses, protrusions, apertures, embossing and combinations thereof.
