NONWOVEN FABRIC FOR ABSORBENT ARTICLE
An object of the present invention is to obtain a nonwoven fabric for an absorbent article that can produce a delicate, soft and smooth feel on the skin when it is contacted with a finger. The nonwoven fabric for an absorbent article has a configuration with a plurality of raised sections, and second hollow sections having, in first bottom sections of first hollow sections in a plurality of furrow sections provided in the spaces between adjacent raised sections, second bottom sections that are formed as depressions opening into the first bottom sections, the distance between the top section of any raised section and the top section of a raised section adjacent to that raised section being 0.5 to 2 mm, and the mean fiber size of the fibers forming at least the raised sections of the nonwoven fabric being 10 to 30 m.
ABSORBENT ARTICLE
An absorbent article includes a surface sheet that is a non-woven fabric including a first fiber layer configured from cotton and thermoplastic resin fibers and a second fiber layer configured from hydrophobic thermoplastic resin fibers. The non-woven fabric includes: a first surface that is the surface on the side facing the skin and that is formed from the second fiber layer; and a second surface that is the surface on the side not facing the skin and that faces an absorbent body. The non-woven fabric is provided with a plurality of protrusions protruding toward the first surface and a plurality of recessed sections that are provided between adjacent protruding sections and that are recessed toward the second surface. The protrusions include a gap section facing the second surface of the non-woven fabric.
Three-dimensional nonwoven materials and methods of manufacturing thereof
Three dimensional nonwoven materials and methods of manufacturing such materials are disclosed. An absorbent article can include an absorbent body and an outer cover. The absorbent article can also include a fluid-entangled nonwoven material. The absorbent body can be disposed between the fluid-entangled nonwoven material and the outer cover. The fluid-entangled nonwoven can include a first surface and a second surface. The nonwoven material can also include a plurality of nodes extending away from abase plane on the first surface towards the absorbent body. The nonwoven material can further include a plurality of openings extending from the first surface to the second surface through the fluid-entangled nonwoven material. Individual openings of the plurality of openings can be disposed between adjacent nodes of the plurality of nodes.
Absorbent article with three-dimensional hot-melt bonded laminate
An absorbent article such as a baby diaper comprising a three-dimensional laminate 30 having a first layer 1 intermittently bonded to a second layer 2 by a heterophase polymer. The topsheet comprises three-dimensional protrusions 9 in the first layer 1 which are not bonded to the second layer 2. The heterophase polymer has an enthalpy of fusion of at least 10 J/g. The laminate may be used on the wearer-facing side of the article as topsheet 24 and/or on the garment-facing side as part of the backsheet 26. The first layer may comprise natural fibers.
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.
THREE-DIMENSIONAL NONWOVEN MATERIALS AND METHODS OF MANUFACTURING THEREOF
Three dimensional nonwoven materials and methods of manufacturing such materials are disclosed. An absorbent article can include an absorbent body and an outer cover. The absorbent article can also include a fluid-entangled nonwoven material. The absorbent body can be disposed between the fluid-entangled nonwoven material and the outer cover. The fluid-entangled nonwoven can include a first surface and a second surface. The nonwoven material can also include a plurality of nodes extending away from a base plane on the first surface towards the absorbent body. The nonwoven material can further include a plurality of openings extending from the first surface to the second surface through the fluid-entangled nonwoven material. Individual openings of the plurality of openings can be disposed between adjacent nodes of the plurality of nodes.

The laminate may be used on the wearer-facing side of the article as topsheet 24 and/or on the garment-facing side as part of the backsheet 26. The first layer may comprise natural fibers.
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.
Fibrous structures having a contact surface
Fibrous structures, for example pre-moistened fibrous structures, having a novel contact surface (micro protrusion surface) and methods for using the fibrous structures and making the fibrous structures are provided.
Absorbent article and manufacturing method therefor
An absorbent article has an absorber disposed between a permeable front surface sheet and a rear surface sheet of a non-woven fabric; wherein the front surface sheet is provided with ridged convex portions continuing in the longitudinal direction of the absorbent article at a specified interval in the width direction of the absorbent article, and provided with dot-like concave embossments at the right side adjacent position and the left side adjacent position alternately at an interval in the longitudinal direction of the absorbent article on the both sides of each of the convex portions, and the concave embossments are arranged in a zigzag pattern as a whole. The convex portion is an inclined surface having a relatively steep gradient on one side and a relatively gentle gradient on the other side, and the cross-sectional shape of the convex portion is an asymmetrical shape.
