HYDRO-FORMED FILM WITH THREE-DIMENSIONAL MICRO-APERTURES
A hydro-formed film includes a polymeric web having a first substantially planar surface and a second substantially planar surface opposite the first substantially planar surface, and a plurality of three-dimensional micro-apertures extending from the first substantially planar surface. The plurality of three-dimensional micro-apertures have a mesh count in a range of about 40 to about 75 apertures per linear inch. The hydro-formed film has a Compression Sensor Point (CSP) count of at least about 80.
DISPOSABLE ABSORBENT ARTICLE
A material web having a film layer and a nonwoven layer, along with methods of making the material web, are described. The material web has a plurality of micro-deformations and a plurality of macro-deformations, each of the macro-deformations having a distal end, wherein a first portion of macro-deformations has an open or partially open distal end and wherein a second portion of macro-deformations has distal ends which are configured differently than the distal ends of the first portion, and wherein the material web forms a portion of the topsheet.
Fluid distribution material for absorbent articles
A fluid distribution material for an absorbent article includes a formed film that includes a first side and a second side opposite the first side. The first side includes a plurality of elongated ridges extending from a first land area, a plurality of valleys defined by adjacent elongated ridges and the first land area, and a plurality of primary apertures located at bottoms of the valleys. The second side includes a plurality of apertured protuberances extending from a second land area. Each of the protuberances includes a continuous sidewall extending from the second land area to a distal end that includes a secondary aperture substantially aligned with a primary aperture. The formed film has a thickness greater than about 0.9 mm under a pressure of 0.071 psi, and a thickness greater than about 0.3 mm under a pressure of 0.6 psi.
MULTI-COMPONENT TOPSHEETS
A multi-component topsheet for an absorbent article includes a first discrete substrate forming about 80% or more of an outer perimeter of the topsheet and a second discrete substrate wherein about 80% or more of an outer perimeter of the second discrete substrate is joined to the first discrete substrate, wherein the topsheet has a single layer of substrate in about 75% or more of the total area of the topsheet and a dual layer of substrate in about 25% or less of the total area of the topsheet.
TOPSHEET COMPRISING NATURAL FIBERS WITH GOOD MECHANICAL STRENGTH
A topsheet for use with an absorbent article is provided and comprises a first layer and a second layer. The first layer is a spunlace nonwoven and comprises at least 15% by weight of natural fibers by total weight of the first layer. The first layer comprises a plurality of protrusions and a plurality of apertures. The first layer and the second layer are in contact with each other between the plurality of the protrusions. The second layer has a plurality of apertures at least partially aligned with the apertures of the first layer. The first layer has a minimum CD strength of at least 3N/(5 cm), according to the Tensile Strength Test Method.
Hydro-formed film with three-dimensional micro-apertures
A method of processing a polymeric web includes providing a forming screen configured for supporting and moving with the web in a machine direction. The forming screen has a plurality of elliptical screen openings, each having a major axis perpendicular to the machine direction and a minor axis parallel to the machine direction. The method includes continuously depositing the web onto the forming screen and passing the web and forming screen through a water stream having a pressure level sufficient to cause the web to be forced into the screen openings, thereby forming protrusions extending from the planar surface of the web. Each protrusion has an apex, an opening at the apex, and an elliptical cross-section parallel to the planar surface of the web. The elliptical cross-section has a protrusion axis ratio that may be selected so as to produce a desired protrusion axis ratio.
Absorbent article
In an absorbent article a three-dimensional opening hole mesh sheet, having a face which faces skin of a wearer of the absorbent article and a reverse or opposite side face within the absorbent article, is combined with an absorber which includes an air-laid pulp non-woven fabric. The mesh sheet has an array of mechanically embossed concave portions forming protrusions on the skin-facing face of the mesh sheet and recesses on the reverse or opposite face, i.e., the unexposed face inside the absorbent article.
Absorbent article
Provided is an absorbent article having a top sheet with an opening-formed area in which openings are formed, and non-opening-formed areas in which no openings are formed, said absorbent article being capable of preventing liquid from remaining on the surface of the opening-formed area of the top sheet. In the present invention, the top sheet is a resin sheet having an opening-formed area (12) in which openings are formed, and non-opening-formed areas (5, 14) in which no openings are formed. The opening-formed area (12) is disposed in an outlet-facing area (16) that faces at least an outlet for fluid from a wearer. The top sheet (2) has a blood modifier layer on the surface of at least the outlet-facing area (16). The blood modifier of the blood modifier layer has an inorganic/organic balance (IOB) of 0 to 0.60, a melting point of not more than 45 C., and an aqueous solubility of 0.05 g or less with respect to 100 g of water at 25 C.
PROCESS FOR MAKING AN ABSORBENT ARTICLE COMPRISING A TOPSHEET/ACQUISITION LAYER LAMINATE
A process of making an absorbent article is disclosed. A liquid permeable topsheet web extending substantially continuously in a machine direction a backsheet web, and an acquisition layer are provided. The topsheet web has first and second surfaces. The backsheet web extends substantially continuously in the machine direction. The acquisition layer has a first and second surface. The topsheet and acquisition layer are aligned in a face to face relationship such that the second surface of the topsheet in in contact with the first surface of the acquisition layer and simultaneously mechanically deformed which combines the topsheet with the acquisition layer. The topsheet web and acquisition layer are nested together such that a majority of the three-dimensional protrusions formed in the topsheet web coincide with and fit together with a majority of the three-dimensional protrusions formed in the acquisition layer to provide a topsheet/acquisition layer laminate web having three-dimensional protrusions.
Multi-component topsheets
A multi-component topsheet for an absorbent article includes a first discrete substrate forming about 80% or more of an outer perimeter of the topsheet and a second discrete substrate wherein about 80% or more of an outer perimeter of the second discrete substrate is joined to the first discrete substrate, wherein the topsheet has a single layer of substrate in about 75% or more of the total area of the topsheet and a dual layer of substrate in about 25% or less of the total area of the topsheet.
