Absorbent products and absorbent core for use in same
An absorbent core assembly for use in a product for absorbing a liquid is disclosed. The core assembly has a first section and a second section. The first section is a quilted porous material that contains a slow acting but high absorption capacity SAP therein. The, second section is a quilted porous material that contains a fast acting but lower absorption capacity SAP therein. The first and second sections are in fluid communication with each other, whereupon a liquid which is exposed to the core assembly flows through the first section to the fast acting SAP in the second section to be absorbed quickly and rapidly by the fast acting SAP therein, while the slow acting SAP desorbs or takes liquid away from the fast acting SAP as well as absorbing the liquid itself to thereby trap the liquid in the core assembly.
ABSORBENT CORE, ARTICLES COMPRISING SAID CORE, AND METHODS OF MAKING
An absorbent core comprising substantially continuous zones of one or more high fluid distribution structures and discontinuous zones of fluid absorption structures surrounding the one or more high fluid distribution structures, wherein the one or more high fluid distribution structures are arranged to distribute fluid across the absorbent core at a speed that is faster than the speed of fluid distribution across the absorbent core by said discontinuous fluid absorption structures, and wherein said continuous zones extend along a path that is substantially parallel to at least a portion of the perimeter of the core, said portion of the perimeter of the core comprising at least a portion of the sides of the core and one of the ends of the core.
ABSORBENT ARTICLES WITH CHANNELS AND/OR POCKETS
An absorbent article includes a front waist edge, a rear waist edge longitudinally opposing the front waist edge, and a longitudinal axis extending from a midpoint of the front waist edge to a midpoint of the rear waist edge. The absorbent article comprises a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core disposed at least partially intermediate the topsheet and the backsheet. The absorbent core comprises a first continuous channel and a second continuous channel, each substantially free of the superabsorbent polymers and at least partially oriented in the longitudinal direction of the absorbent. The first and second channels each have lateral widths parallel to the lateral axis. A profile of the lateral widths of each channel over a longitudinal length of at least 50 mm of the channel taken along the longitudinal axis is substantially constant. The average lateral width of the first channel differs from an average lateral width of the second channel.
Disposable diaper having first and second absorbent structures and channels
Disposable absorbent diapers are provided with improved comfort, fit and liquid transportation. The absorbent core of the disposable absorbent diapers includes a first absorbent structure and a second absorbent structure. Each absorbent structure includes a substrate layer and an absorbent layer with at least one channel. The absorbent layers are mirror images of one another and are combined such that a channel of the second absorbent layer superposes a corresponding channel of the first absorbent layer to form a channel extending through the thickness of the absorbent core.
ADULT DISPOSABLE ABSORBENT ARTICLES AND ARRAYS OF SAID ARTICLES COMPRISING ABSORBENT CORES HAVING CHANNELS
An array of packages comprising two or more different sizes of disposable absorbent articles may comprise first and second articles comprising first and second cores having different Channel Spacings, Curvatures, Arm Angles, and/or Lengths.
Absorbent core, articles comprising said core, and methods of making
An absorbent core comprising substantially continuous zones of one or more high fluid distribution structures and discontinuous zones of fluid absorption structures surrounding the one or more high fluid distribution structures, wherein the one or more high fluid distribution structures are arranged to distribute fluid across the absorbent core at a speed that is faster than the speed of fluid distribution across the absorbent core by said discontinuous fluid absorption structures, and wherein said continuous zones extend along a path that is substantially parallel to at least a portion of the perimeter of the core, said portion of the perimeter of the core comprising at least a portion of the sides of the core and one of the ends of the core.
METHOD OF MAKING ABSORBENT STRUCTURES WITH CHANNELS
A method for making an absorbent structure for use in a disposable absorbent article is provided. The method involves the steps of providing a first moving surface having an absorbent layer-forming reservoir, providing a supply of absorbent material, and depositing a portion of the supply of absorbent material into the absorbent layer-forming reservoir. The method further involves associating the portion of the supply of absorbent material with a first substrate layer and/or a second substrate layer to define an absorbent structure having a channel therein corresponding to the one or more raised strips, and bonding the first substrate layer to the second substrate layer through the channel. The channel is substantially free of the absorbent material.
Fluid distribution material for absorbent articles
A fluid distribution material for use in an absorbent article includes a formed film layer, with a basis weight of between about 10 gsm and about 25 gsm, a user-facing side, and a garment-facing side. The formed film layer includes a plurality of apertured protuberances, numbering 10 to 40 per linear inch. The garment-facing side has a plurality of apertures aligned with the plurality of apertured protuberances, with land areas therebetween. A nonwoven layer, with a basis weight of between about 10 gsm and about 15 gsm, is laminated to the garment-facing side of the formed film layer. The nonwoven layer includes a plurality of fibers adjacent the land areas. Fibers adjacent the land areas are gathered a higher density than fibers located adjacent the plurality of apertures. The fluid distribution material has a compressibility of less than 10% between pressures of 0.21 psi and 0.60 psi.
DISPOSABLE DIAPERS
Disposable absorbent diapers are provided with improved comfort, fit and liquid transportation. The absorbent core of the disposable absorbent diapers includes at least one absorbent structure having a substrate layer and an absorbent layer with channels.
