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.
Process for making an absorbent article comprising a topsheet/acquisition layer laminate
A process of making an absorbent article comprising providing a liquid permeable topsheet web extending substantially continuously in a machine direction. The topsheet web having a first and second surface and a backsheet web extending substantially continuously in the machine direction and an acquisition layer having a first and second surface. The process comprises aligning the topsheet web and the acquisition layer 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 deforming and combining the topsheet web together 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.
Absorbent article with three-dimensional film for liquid distribution
An absorbent article with a three-dimensional film transfer layer having an open lattice structure formed from a single film for improved user properties.
ACQUISITION AND DISTRIBUTION COMPOSITE, ABSORBENT HYGIENE ARTICLE AND METHOD OF PRODUCTION
An acquisition and distribution composite has a liquid acquisition side formed of first nonwoven fibers, a hydrophilic core, and a liquid delivery side comprising second nonwoven fibers. The composite has an asymmetric structure, such that the linear density measured in dtex of the first nonwoven fibers is at least 0.7 dtex greater than that of the second nonwoven fibers. In addition, an absorbent hygiene article is formed from the acquisition and distribution composite. A method for producing the acquisition and distribution composite includes providing the three layers and hydroentangling the three-layer structure.
ABSORBENT ARTICLE COMPRISING A CARDED CALENDERED NONWOVEN
An absorbent article such as a diaper comprising as component a carded calendered nonwoven comprising synthetic staple fibers, wherein the synthetic staple fibers comprise a polypropylene polymer matrix, an ethylene-propylene copolymer and a fatty acid amide, and optionally natural fibers. The nonwovens may be used in application where a soft and affordable nonwoven is desired, for example in the topsheet or backsheet outer cover nonwoven.
CARDED CALENDERED NONWOVENS
A carded calendered nonwoven comprising synthetic staple fibers. The synthetic staple fibers comprise a polypropylene polymer matrix, an ethylene-propylene copolymer and a fatty acid amide. The nonwovens of the present disclosure may be used in application where a soft and affordable nonwoven is desired, for example disposable absorbent articles, such as pants or diapers.
Stiff nanocomposite film for use in an absorbent article
A thin nanocomposite film for use in an absorbent article (e.g., sanitary napkin) is provided. The film contains a first ethylene polymer having a density of about 0.94 g/cm3 or less, second ethylene polymer having a density of greater than 0.94 g/cm3, and nanoclay having an organic surface treatment. The present inventors have discovered that through selective control over the particular type and concentration of the components used to form the film, as well as the manner in which it is formed, the properties of the film can be significantly improved.
Laminates with bonded webs
Laminates with a layer of bonded nonwoven material attached to a layer of film.
LIQUID BARRIER AND AIR-PERMEABLE BACKSHEET
Backsheets having a combination of desirable liquid barrier properties and air permeability are provided. The backsheets include outermost spunbond layers and two or more fine-fiber containing nonwoven layers.
Wearable article comprising an elastic belt laminate
A wearable article comprising an elastic laminate with an inner web and an outer web being in a face to face relationship, and a skin-facing outer surface and a garment-facing outer surface. The elastic laminate has a total caliper when subjected to the NMR MOUSE method as defined herein, the total caliper having a first 200 m sub-caliper corresponding to 200 m of the total caliper starting from the skin-facing outer surface and extending towards the garment-facing outer surface, and a last 200 m sub-caliper corresponding to 200 m of the total caliper starting from the garment-facing outer surface and extending towards the skin-facing outer surface. The elastic laminate has a % Liquid Ratio in the first 200 micron sub-caliper to total caliper of less than 20% after 1 minute according to the NMR MOUSE method.
