DISPOSABLE ABSORBENT HYGIENE PRODUCT WITH TOPSHEET AND ACQUISITION LAYER
A disposable absorbent hygiene product is provided, including a main part having a body facing surface intended to face the body of a user and a garment facing surface intended to face away from the body of a user. The main part includes a liquid permeable topsheet at the body facing surface, a liquid impermeable backsheet at the garment facing surface, and an absorbent assembly arranged between the topsheet and the backsheet. The liquid permeable topsheet material includes a hydrophilically treated polypropylene spunbond nonwoven or spunbond/meltblown composite nonwoven, having a basis weight of from 8 to 20 g/m.sup.2. An acquisition layer material is provided sandwiched between said topsheet and said absorbent assembly, being an through air bonded nonwoven.
Disposable absorbent hygiene product comprising absorbent assembly
A disposable absorbent hygiene product is provided, including a main part having a body facing surface intended to face the body of a user and a garment facing surface intended to face away from the body of a user. The main part includes a liquid permeable topsheet at the body facing surface, a liquid impermeable backsheet at the garment facing surface, and an absorbent assembly arranged between said topsheet and said backsheet. The absorbent assembly includes a first absorbent core and a second absorbent core arranged in a stacked relationship.
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 intermediate layer are provided. The topsheet web has first and second surfaces. The backsheet web extends substantially continuously in the machine direction. The intermediate layer has a first and second surface. The topsheet and intermediate 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 intermediate layer and simultaneously mechanically deformed which combines the topsheet with the intermediate layer. The topsheet web and intermediate 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 intermediate layer to provide a topsheet/intermediate layer laminate web having three-dimensional protrusions.
Method of Making an Absorbent Composite and Absorbent Articles Employing the Same
A method of making an absorbent composite that includes a first fabric, a second fabric, and particles positioned between the two fabrics and absorbent articles made from the absorbent composite. The particles are secured between the two fabric using adhesive, thermal plastic or combinations thereof. The fabrics are bonded together in a manner that limits particle movement between the fabrics. The bond pattern may define pockets or other shapes. In applications in which the bond pattern forms pockets, the particles may be positioned in the pockets. The particles may be SAP particles or other particles with advantageous properties.
Absorbent article comprising flexible polymeric foam and intermediates
Absorbent articles are described comprising a first absorbent layer comprising a polymeric foam. In one embodiment, the polyurethane foam comprises the reaction product of a polymeric polyisocyanate component having an equivalent weight of no greater than 250 g/equivalent; and a polyol component. The polyol component comprises one or more polyether polyols such that the polyol component comprises an average equivalent weight ranging from 500 to 2000 g/equivalent; an ethylene oxide content ranging from 15-30 wt.-%; a secondary hydroxyl content of at least 55 wt.-% and less than 80 wt.-% of the total hydroxyl content of the polyol component; and less than 5 wt-% water. Also described are various composites comprising the polyurethane foam described herein in combination with another substrate such as a second absorbent layer, a fluid impervious backsheet, and/or a fluid pervious topsheet.
ABSORBENT BODY, METHOD FOR MANUFACTURING SAME, AND ABSORBENT ARTICLE
To make gel blocking less likely to occur, to enable and improve liquid absorption speed and absorption capability and to enable reversion to be prevented, without impairing the feeling when worn. An absorbent body is provided with a water-absorbent fiber stack including pulp fibers and a highly water-absorbent polymer, and a cover sheet covering at least a skin-facing surface of the water-absorbent fiber stack. Multiple protruding portions which protrude outward, and recessed portions that are recessed and are adjacent to the protruding portions are formed on the non-skin facing surface of the cover sheet, and the water-absorbent fiber stacks are stacked in the recessed portions.
Unitary absorbent structures comprising an absorbent core and/or an acquisition and dispersion layer for absorbent articles
The present invention relates to a unitary absorbent structure and method thereof wherein said unitary absorbent structure comprises an absorbent core (5) and/or an acquisition and dispersion layers (2) (3) and comprising at least one non-woven fibrous substrate layer (23) having a void volume suitable to be penetrated by super absorbent particles. The super absorbent particles are dispersed in the substrate layer (23) according to a size distribution gradient by vacuum (8) and vibration along the depth direction or z-direction of said absorbent core (5) and/or acquisition (2) and dispersion (3) layers, the smaller particles are placed on the bodyside of the absorbent articles and the larger particles are located on the opposite side of the absorbent articles.
ABSORBENT ARTICLES HAVING CHANNEL-FORMING AREAS AND WETNESS INDICATOR
An absorbent article comprising an absorbent core having a longitudinally extending channel-forming area and a wetness indicator. The core wrap comprises a top side and a bottom side, which are attached to each other through areas substantially free of absorbent material, so that when the absorbent material swells upon absorption of a liquid a channel is formed along the area substantially free of absorbent material.
DISPOSABLE ABSORBENT HYGIENE PRODUCT COMPRISING ABSORBENT ASSEMBLY
A disposable absorbent hygiene product is provided, including a main part having a body facing surface intended to face the body of a user and a garment facing surface intended to face away from the body of a user. The main part includes a liquid permeable topsheet at the body facing surface, a liquid impermeable backsheet at the garment facing surface, and an absorbent assembly arranged between said topsheet and said backsheet. The absorbent assembly includes a first absorbent core and a second absorbent core arranged in a stacked relationship.
DISPOSABLE ABSORBENT HYGIENE PRODUCT COMPRISING ABSORBENT ASSEMBLY
A disposable absorbent hygiene product is provided, including a main part having a body facing surface intended to face the body of a user and a garment facing surface intended to face away from the body of a user. The, main part includes a liquid permeable topsheet at the body facing surface, a liquid impermeable backsheet at the garment facing surface, and an absorbent assembly arranged between the topsheet and the backsheet. In front and back regions of the absorbent assembly, the absorbent assembly includes cellulosic fibers mixed with super absorbent polymers, with a central region of the absorbent assembly providing from 70% to 100% of the total retention capacity of the absorbent assembly.
