Definitions

  • the absorbent core of current absorbent articles does not adequately meet current performance objectives.
  • the desirable absorbent core liquid uptake and distribution functionalities required for upstream narrower crotch higher efficiency absorbent article designs is also beyond current capabilities. Consequently, there remains a need for absorbent structures which can provide improved fluid uptake of liquid insults and improved liquid distribution to move liquid out of the target area between liquid insults to maintain this desirable liquid uptake behavior for the life of the product.
  • Fig. 9 representatively shows a longitudinal, cross-sectional view of another absorbent core of the invention which includes a bottom layer region composed of a heterogeneous laminate wherein the distribution of superabsorbent material is arranged to provide a nonuniform, zoned basis weight of superabsorbent within the bottom layer region;
  • This low saturation, intake layer region is desirably employed in addition to a separately provided surge management portion or layer, and can provide an intake functionality which is additional to that provided by the material of the surge layer.
  • the intake layer region can be located on the body side of the absorbent structure, and can be configured to not extend over the entire area expanse of the total, overall absorbent structure. Accordingly, the primary, body side layer region is employed as an intake layer region, and is not employed as the high saturation, wicking layer region. This arrangement also allows the intake layer region to be in a substantially direct contact with the incoming liquid, thereby allowing for a more immediate access to the incoming liquid and a more effective intake function.
  • the Combined Conductance-Wicking value (C) of the system can be at least about 14+10 "6 cm 3 .
  • the Combined Conductance-Wicking value can be at least about 15*10 "6 cm 3 , and optionally can be at least about 16*10 " * cm 3 to provide an improved balance of performance.
  • the Combined Conductance- Wicking value can be at least about 18* 10 "6 cm 3 to provide desired benefits.
  • the target area of the product, in its dry state ordinarily does not have enough void volume available to efficiently absorb the initial insult of liquid, such as urine.
  • a material of this type forms the outercover of a HUGGIES SUPREME diaper, which is commercially available from Kimberly-Clark Corporation.
  • the backsheet 22 typically provides the outer cover of the article.
  • the article may include a separate outer cover component member which is additional to the backsheet.
  • the fibers may be hydrophilized, for example, by treatment with silica, treatment with a material which has a suitable hydrophilic moiety and is not readily removable from the fiber, or by sheathing the nonwettable, hydrophobic fiber with a hydrophilic polymer during or after the formation of the fiber.
  • a material which has a suitable hydrophilic moiety and is not readily removable from the fiber or by sheathing the nonwettable, hydrophobic fiber with a hydrophilic polymer during or after the formation of the fiber.
  • selected blends of the various types of fibers mentioned above may also be employed.
  • the leg elastic members 34 may include a carrier sheet to which are attached a grouped set of elastics composed of a plurality of individual elastic strands.
  • the elastic strands may intersect or be interconnected, or be entirely separated from each other.
  • the carrier sheet may, for example, comprise a 0.002 cm thick polymer film, such as a film of unembossed polypropylene material.
  • the elastic strands can, for example, be composed of LYCRA elastomer available from DuPont, a business having offices in Wilmington, Delaware.
  • Each elastic strand is typically within the range of about 470 - 1500 decitex (dtx), and may be about 940 - 1050 dtx.
  • three or four strands can be employed for each elasticized legband.
  • Timer (140) capable of reading 120 minutes at one second intervals.
  • a suitable technique for measuring the liquid contact angle with a fiber is described in U.S. Patent No. 5,364,382, the entire disclosure of which is incorporated herein by reference in a manner that is consistent herewith.
  • the wettability of fibers can be determined using contact angle measurements on fibers.
  • Repeat cycle, single fiber contact angle measurements using distilled water can be performed with a Cahn Surface Force Analyzer (SFA222) and WET-TEK data analysis software.
  • the SFA222 is available from Cahn Instruments, Inc., of Cerritos, Calif.
  • WET-TEK software is available from Biomaterials International, Inc., of Salt Lake City, Utah. Fibers are tested through three measurement cycles, and the bath of distilled water is changed between cycles one and two.
  • the liquid contact angle for the fiber material is determined by taking the arithmetic average of the three measurements.
  • the test instrument is operated in accordance with the standard operating techniques described in the Cahn SFA-222 System Instruction Manual supplied by the manufacturer.

Abstract

Un article absorbant caractéristique comporte une partie centrale absorbante à couches absorbantes multiples, les couches absorbantes interagissant de manière à transférer de préférence le liquide absorbé dans une couche d'imbibition haute saturation désignée. Le fait que le liquide se trouve dans cette couche d'imbibition permet d'accroître le potentiel de cette couche à déplacer le liquide par capillarité en raison du taux de saturation élevé et d'une quantité croissante de liquide disponible. Dans des aspects supplémentaires, au moins une zone de couche primaire peut comporter une répartition non uniforme de masses surfaciques zonée de manière sélective. Des configurations particulières de la zone de couche primaire peuvent être formées, dans lesquelles une zone cible de la zone de couche primaire comporte une masse surfacique inférieure à celle d'une autre partie non-cible de la zone de couche primaire.
