ABSORBENT ARTICLES COMPRISING GARMENT-FACING LAMINATES
An absorbent article is provided. The absorbent article comprises a liquid permeable topsheet on a wearer-facing side of the absorbent article and a garment-facing laminate on a garment-facing side of the absorbent article. The garment-facing laminate comprises a first nonwoven layer and a second layer joined to the first nonwoven layer. The first nonwoven layer comprises a plurality of apertures. At least 3 of the plurality of apertures in a repeat unit have a different Effective Aperture Area, according to the Aperture Test herein, a different shape, or a different Absolute Feret Angle, according to the Aperture Test herein. The absorbent article comprises an absorbent core disposed at least partially intermediate the liquid permeable topsheet and the garment-facing laminate.
Textile Backsheet
Textile backsheets including a nonwoven fabric and film, such as a vapor-permeable and liquid impermeable (VPLI) film or a non-permeable film, are provided, wherein the nonwoven fabric is directly or indirectly bonded to the film. Methods of making such textile backsheets and absorbent articles including the textile backsheets are also provided.
ABSORBENT ARTICLE
An absorbent article, such as, a garment-like absorbent article, can have a front region, a back region, and a crotch region extending between and interconnecting the front region and the back region. Each of the front region and the back region can have an elastic material. The absorbent article can have an absorbent core wherein a portion of the absorbent core can be located in the crotch region, a portion of the absorbent core can be located in a portion of the front region, and a portion of the absorbent core can be located in a portion of the back region. Within each of the front region and the back region, an overlapping region can exist where the absorbent core is in an overlapping configuration with the elastic material within the front region and the back region.
Patterned apertured webs
A patterned apertured web is disclosed. The patterned apertured web includes a plurality of land areas in the patterned apertured web and a plurality of apertures defined in the patterned apertured web. At least some land areas of the plurality of land areas surround at least some apertures of the plurality of apertures. The patterned apertured web has an Effective Open Area in the range of about 3% to about 30%, according to the Aperture Test herein. The plurality of apertures include a first set of apertures defining a first shape and a second set of apertures defining a second shape. The first shape is positioned within the second shape.
Absorbent article
An absorbent article includes a topsheet comprising a composite sheet. In the composite sheet, projections that protrude toward the skin of the wearer are formed by a first sheet protruding in a direction away from a second sheet at portions other than bonding portions. A plurality of first oblique bonding portion rows and a plurality of second oblique bonding portion rows are formed, and a long bonding portion elongated in a longitudinal direction is formed at each intersection of the first oblique bonding portion rows and the second oblique bonding portion rows. Laterally long projections elongated in a width direction are formed in a dispersed manner in the longitudinal direction and the width direction. Each laterally long projection is surrounded by two first oblique bonding portion rows and two second oblique bonding portion rows, and the long bonding portion is formed between adjacent laterally long projections in the width direction.
CONTOURED FILM WITH MICRO-PROTRUSIONS
A polymeric film is provided, the film comprising one or more land portions that are substantially coplanar in a base plane and a plurality of distended portions separated from one another by the one or more land portions. The distended portions bow distally outward from the base plane. The polymeric film further comprises a plurality of annular micro-protrusions extending outward from the distal film surface, each protrusion having an apex. A portion of the plurality of annular micro-protrusions extends from each of the one or more land portions of the polymeric film and from each of the distended portions of the polymeric film.
Patterned Apertured Webs
A patterned apertured web is disclosed. The patterned apertured web includes a plurality of land areas in the patterned apertured web and a plurality of apertures defined in the patterned apertured web. At least some land areas of the plurality of land areas surround at least some apertures of the plurality of apertures. The patterned apertured web has an Effective Open Area in the range of about 3% to about 30%, according to the Aperture Test herein. The patterned apertured web has a plurality of Interaperture Distances, according to the Aperture Test herein. The Interaperture Distances have a distribution having a median and a mean. The plurality of apertures include a first set of apertures defining a first shape and a second set of apertures defining a second shape.
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 method can include providing a precursor web that includes a plurality of fibers and transferring the precursor web to a forming surface having a plurality of forming holes. The method can also include directing a plurality of pressurized fluid streams of entangling fluid in a direction towards the precursor web on the forming surface to move at least some of the fibers into the plurality of forming holes to create a fluid entangled web. The method can further include removing the fluid entangled web from the forming surface such that the at least some of the fibers moved into the plurality of forming holes provide a plurality of nodes. The plurality of nodes can have an anisotropy value greater than 1.0 as determined by the Node Analysis Test Method.
WIRELESS LOCATING OF AN INCONTINENCE DETECTION PAD VIA A PATIENT BED
An incontinence detection pad for detecting incontinence events includes a moisture absorbent layer that has non-embossed areas and embossed areas. The non-embossed areas have a first density of fibers of the layer, and the embossed areas have a second density of fibers of the layer that is greater than the first density. The incontinence detection pad further includes a plurality of electrodes positioned beneath the moisture absorbent layer and a transmitter connected to the plurality of electrodes and configured to transmit a signal indicative of a status of the moisture absorbent layer.
Garment-facing laminates and methods for making the same
An absorbent article including a liquid permeable topsheet on a wearer-facing side of the absorbent article and a garment-facing laminate on a garment-facing side of the absorbent article is disclosed. The garment-facing laminate includes a backsheet film and a nonwoven layer joined to the backsheet film. The nonwoven layer defines a plurality of apertures. At least 3 of the plurality of apertures in a repeat unit have a different Effective Aperture Area, according to the Aperture Test herein, a different shape, and a different Absolute Feret Angle, according to the Aperture Test herein. The absorbent article includes an absorbent core disposed at least partially intermediate the liquid permeable topsheet and the garment-facing laminate.
