Definitions
- This invention is directed to an absorbent garment that is designed to reduce or eliminate any tendency of the garment to droop when loaded.
- Diapers and other absorbent garments are intended to fit a wearer and to stay on the wearer until removed by the wearer or caregiver. While still in place on the wearer, diapers often droop or sag between the legs of the wearer, particularly when the garment is loaded with bodily wastes. This drooping or sagging may be the result of one or more factors.
- the proportion of the garment dimensions appears to be a key factor in garment drooping.
- some diapers are very long and extend from above the wearer's navel through the crotch region and up the wearer's back. These diapers have front and/or back waist regions that are applied above the wearer's natural waistline.
- the added weight in the crotch region pulls the garment down.
- the waist region of the garment comes to rest along the wearer's waistline, thereby resulting in a sagging crotch region.
- the garment comes to rest on the natural bond structure of the wearer' s hips.
- Some diapers have wide crotch regions.
- Absorbent garments typically include elasticized portions around the leg openings and the waist opening.
- the garment may slide down the wearer's torso, often past the wearer's waistline.
- the waist elastic may be another factor that contributes to a drooping tendency of an absorbent garment.
- the absorbent garment of the invention includes an absorbent chassis that defines a waist opening and two leg openings.
- the longitudinal length of the garment measured from a front waist edge of the chassis to a back waist edge of the chassis, is proportionally shorter than conventional diapers dependent on the size of the baby or wearer.
- the waist regions of the garment are designed to be situated at a wearer's waistline when worn.
- the proportionality of the longitudinal length can be assessed with respect to an expanded width of the absorbent chassis measured from a distal edge of one tab to a distal edge of an opposite tab along the back waist region of the absorbent chassis, wherein the distal edges of the tabs define transverse distal edges of the back waist region.
- the longitudinal length of the absorbent chassis divided by the expanded width of the absorbent chassis is referred to as a diaper length ratio (DLR).
- the absorbent garment suitably has a diaper length ratio of about 0.85 or less, or about 0.8 or less, or between about 0.6 and about 0.8.
- the crotch region of the absorbent garment may also be narrower than the crotch region in corresponding conventional absorbent garments. A narrower crotch region also contributes to a reduction in droopiness.
- the longitudinal length of the absorbent chassis multiplied by the width of the crotch region and divided by the expanded width of the absorbent chassis is referred to as a droop design ratio (DDR).
- DDR droop design ratio
- the absorbent garment suitably has a DDR of about 150 millimeters (mm) or less, or between about 120 and about 140 mm.
- Absorbent garments typically include an absorbent core positioned between an outer cover and a body side liner.
- the combined lengths of the absorbent core and the total absorbent chassis, relative to the width of the crotch region and the expanded width of the absorbent chassis, may be another indication of a garment having a relatively short longitudinal length and/or a relatively narrow crotch region.
- a sum of the longitudinal length of the absorbent chassis and the longitudinal length of the absorbent core, multiplied by the width of the crotch region and divided by the expanded width of the absorbent chassis is referred to as an absorbent length design ratio (ALR).
- ARR absorbent length design ratio
- the absorbent garment suitably has an ALR of about 280 mm or less, or between about 220 and about 250 mm.
- ALR ALR of about 280 mm or less, or between about 220 and about 250 mm.
- the absorbent garments of the invention may have a saturated retention capacity of about 150 grams or greater.
- the absorbent garment may have a waist elastic in the front waist region and/or in the back waist region with sufficient retraction force to maintain the garment in place on the wearer.
- elastic components can be incorporated in the chassis components.
- an elastic film can be incorporated in the chassis in such a manner that the elastic film provides sufficient retraction force to maintain the garment in place on the wearer.
- elastic components can be attached to the lateral edges of the back waist region and are referred to as elastic ears.
- the term "waist elastic” may be used to describe any of the elastic elements in these embodiments, or a combination of the elements described in these embodiments.
- the waist elastic may have a retraction force of about 100 grams or greater at 30% extension upon return after being extended at least 50%. Retraction force is measured as a sum of all of the waist elastic components located between the fastening components in the back waist region in the combined state in the diaper.

- Fig. 2 is a plan view of the absorbent garment of Fig.
- Fig. 3 is a plan view of the absorbent garment of Fig. 1 in a stretched flat state, and showing the surface of the garment that faces the wearer when the article is worn, according to one embodiment of this invention.
- DEFINITIONS [0020] Within the context of this specification, each term or phrase below will include the following meaning or meanings. [0021] "Absorbent garment” includes personal care garments, medical garments, and the like. The term “disposable garment” includes garments that are typically disposed of after 1-5 uses.
- personal care garment includes diapers, diaper pants, training pants, swim wear, absorbent underpants, adult incontinence products, feminine hygiene products, and the like.
- “Attached” refers to the joining, adhering, connecting, bonding, or the like, of at least two elements. Two elements will be considered to be attached together when they are attached directly to one another or indirectly to one another, such as when each is directly attached to intermediate elements.
- “Layer” when used in the singular can have the dual meaning of a single element or a plurality of elements.
- “Longitudinal” and “transverse” have their customary meaning, as indicated by the longitudinal and transverse axes depicted in Figs. 3 and 4.
- Meltblown fiber refers to fibers formed by extruding a molten thermoplastic material through a plurality of fine, usually circular, die capillaries as molten threads or filaments into converging high velocity gas (e.g., air) streams which attenuate the filaments of molten thermoplastic material to reduce their diameter, which may be to microfiber diameter.
- high velocity gas e.g., air
- meltblown fibers are carried by the high velocity gas stream and are deposited on a collecting surface to form a web of randomly dispersed meltblown fibers.
- meltblown fibers are microfibers which may be continuous or discontinuous, are generally smaller than about 0.6 denier, and are generally self bonding when deposited onto a collecting surface.
- nonwoven and nonwoven web refer to materials and webs of material having a structure of individual fibers or filaments which are interlaid, but not in an identifiable manner as in a knitted fabric.
- fiber and “filament” are used herein interchangeably.
- Nonwoven fabrics or webs have been formed from many processes such as, for example, meltblowing processes, spunbonding processes, air laying processes, and bonded carded web processes.
- the basis weight of nonwoven fabrics is usually expressed in ounces of material per square yard (osy) or grams per square meter (gsm) and the fiber diameters are usually expressed in microns. (Note that to convert from osy to gsm, multiply osy by 33.91.)
- Polymers include, but are not limited to, homopolymers, copolymers, such as for example, block, graft, random and alternating copolymers, terpolymers, etc. and blends and modifications thereof.
- polymer shall include all possible geometrical configurations of the material. These configurations include, but are not limited to isotactic, syndiotactic and atactic symmetries.
- Spunbond fiber refers to small diameter fibers which are formed by extruding molten thermoplastic material as filaments from a plurality of fine capillaries of a spinnerette having a circular or other configuration, with the diameter of the extruded filaments then being rapidly reduced, as known in the art. Spunbond fibers are quenched and generally not tacky when they are deposited onto a collecting surface.
- Spunbond fibers are generally continuous and often have average deniers larger than about 0.3, more particularly, between about 0.6 and 10.
- "Superabsorbent,” “superabsorbent polymer,” or “superabsorbent material” refers to a water-swellable, water-insoluble organic or inorganic material capable, under the most favorable conditions, of absorbing at least about 15 times its weight and, more desirably, at least about 30 times its weight in an aqueous solution containing 0.9 weight percent sodium chloride.
- the superabsorbent materials can be natural, synthetic and modified natural polymers and materials.
- the superabsorbent materials can be inorganic materials, such as silica gels, or organic compounds such as cross-linked polymers.
- an absorbent garment having dimensions of certain proportions results in a reduction or elimination of drooping or sagging in a crotch region. More particularly, dimensional proportions may be drawn between a longitudinal length of the absorbent chassis, an extended width of a back waist region of the garment, a width of a crotch region of the garment, and/or a longitudinal length of an absorbent core within the garment. [0032]
- the principles of the present invention can be incorporated into any suitable pant-like disposable absorbent garment.
- a diaper 20 is illustrated in a fastened position as the garment would appear when worn.
- Figs. 2 and 3 illustrate the diaper 20 in a stretched flat state in which the various dimensions of the garment are measured. More particularly, Fig. 2 is a view of a garment-facing surface of the diaper 20, and Fig. 3 is a view of a body-facing surface of the diaper 20.
- the diaper 20 includes an absorbent chassis 32 defining a front waist region 22, a back waist region 24, and a crotch region 26 interconnecting the front and back waist regions.
- the absorbent chassis 32 defines a three-dimensional pant configuration having a waist opening 50 and a pair of leg openings 52.
- the chassis 32 includes a body side liner 42 which is configured to contact the wearer, and an outer cover 40 opposite the body side liner which is configured to contact the wearer's clothing.
- An absorbent core 44 (Fig. 3) is positioned or located between the outer cover 40 and the body side liner 42.
- the front waist region 22 includes the portion of the diaper 20 which, when worn, is positioned on the front of the wearer while the back waist region 24 includes the portion of the diaper which, when worn, is positioned on the back of the wearer.
- the crotch region 26 of the diaper 20 includes the portion of the diaper which, when worn, is positioned between the legs of the wearer and covers the lower torso of the wearer.
- the chassis 32 also defines a pair of longitudinally opposed waist edges, which are designated front waist edge 38 and back waist edge 39.
- the front waist region 22 is contiguous with the front waist edge 38
- the back waist region 24 is contiguous with the back waist edge 39.
- the waist edges 38, 39 are configured to encircle the waist of the wearer when the garment is worn.
- a longitudinal length of the absorbent chassis 32 is the distance between the front waist edge 38 and the back waist edge 39, which can be measured according to the test method described in detail below.
- the longitudinal length of the absorbent chassis 32 is short compared to conventional garments designed to fit wearers of the same size. More particularly, the garments of the invention fit lower on a wearer, thereby using the small of the wearer's back to support the weight of the diaper. Consequently, less drooping occurs than with conventional diapers.
- arrows 48 and 49 depicting the orientation of the longitudinal axis and the transverse axis, respectively, of the diaper 20 are illustrated in Figs.
- the illustrated absorbent chassis 32 includes a pair of transversely opposed ear panels or tabs 34, which extend transversely outward along the back waist region 24 of the absorbent chassis 32.
- the tabs 34 may be integrally formed with the outer cover 40 and/or the body side liner 42, or may include two or more separate elements. Additionally, the tabs 34 may include a stretchable and/or elastomeric material capable of stretching in a direction generally parallel to the transverse axis 49 of the diaper 20. Additionally, one or more of the chassis materials maybe composed of an elastic material, in which case the addition of elastic strands or other elastic materials may not be necessary to deliver the required retraction force.
- An expanded width of the absorbent chassis 32 can be measured in a manner similar to the longitudinal length measurement test method described below, but with the measurements made from a distal edge 36 of one tab 34 to a distal edge 36 of the other tab 34 while one of the tabs is attached to a stationary object and a 1500 gram weight is attached to the other tab and permitted to hang for 10 seconds.
- the expanded width of the absorbent chassis 32 measured in this manner provides an indication of the size of the garment with respect to a size of an intended wearer. More particularly, the absorbent garment 20 of the invention has a reduced longitudinal length compared to conventional absorbent garments, but the expanded width of the absorbent chassis 32 has not been reduced in the absorbent garment 20 of the invention compared to conventional absorbent garments.
- the expanded width of the absorbent chassis 32 can be used as a general garment size indicator when comparing garments of this invention to conventional absorbent garments to ensure that the garments being compared are intended to fit wearers of approximately the same size.
- a width of the crotch region 26 may be narrower in the diaper 20 compared to conventional absorbent garments, as explained below in proportion to other dimensions of the diaper 20. The width of the crotch region 26 is measured across the narrowest transverse width of the crotch region 26 when the diaper 20 is in a laid flat state with any elastic components either removed or otherwise disabled to prevent any interference with the crotch width measurement, similar to the longitudinal length measurement test method described below.
- the absorbent core 44 can be any structure which is generally compressible, conformable, non-irritating to the wearer's skin, and capable of absorbing and retaining liquids and certain body wastes at anticipated levels despite the narrowed crotch width.
- the absorbent core 44 can be manufactured in a wide variety of sizes and shapes, and from a wide variety of liquid absorbent materials commonly used in the art.
- the absorbent core 44 can suitably include a matrix of hydrophilic fibers, such as a web of cellulosic fluff, mixed with particles of a high-absorbency material commonly known as superabsorbent material, hi a particular embodiment, the absorbent core 44 includes a matrix of cellulosic fluff, such as wood pulp fluff, and superabsorbent hydrogel-forming particles.
- the wood pulp fluff can be exchanged with synthetic, polymeric, meltblown fibers or with a combination of meltblown fibers and natural fibers.
- the superabsorbent particles can be substantially homogeneously mixed with the hydrophilic fibers or can be nonumformly mixed.
- the fluff and superabsorbent particles can also be selectively placed into desired zones of the absorbent core 44 to better contain and absorb body exudates.
- the absorbent core 44 can have variable thickness, with greater thickness in "target" areas, such as in a central portion of the crotch region.
- the concentration of the superabsorbent particles can also vary through the thickness of the absorbent core 44.
- the absorbent core 44 can include a laminate of fibrous webs and superabsorbent material or other suitable means of maintaining a superabsorbent material in a localized area.
- the absorbent core 44 may or may not be wrapped or encompassed by a suitable tissue wrap that maintains the integrity and/or shape of the absorbent core 44.
- the absorbent core 44 may contain a body side liner and/or a moisture barrier in addition to absorbent and distribution elements. In such embodiments, the absorbent core 44 may be attached to the outer cover 40 and need not be sandwiched between two layers.
- the absorbent core 44 may also contain leg elastics in embodiments such as this. The longitudinal length of the absorbent core 44 is measured from a front edge 43 of the absorbent core to a back edge 45 of the absorbent core in a laid flat position, negating any elastomeric effects from other components in the diaper 20.
- Suitable superabsorbent materials can be selected from natural, synthetic, and modified natural polymers and materials.
- the superabsorbent materials can be inorganic materials, such as silica gels, or organic compounds, such as crosslinked polymers. Suitable superabsorbent materials are available from various commercial vendors, such as Dow Chemical Company located in Midland, Michigan, U.S.A., and Degussa Superabsorber in Greensboro, North Carolina, U.S.A. Typically, a superabsorbent material is capable of absorbing at least about 15 times its weight in water, and desirably is capable of absorbing more than about 25 times its weight in water. [0041]
- the absorbent core 44 has a shorter length and width than the outer cover 40 and body side liner 42 and is spaced inboard from both the lateral side edges and the end edges of the outer cover and body side liner.
- the longitudinal length of the absorbent core 44 is measured in essentially the same manner as the longitudinal length of the absorbent chassis 32 as a whole, as described in the longitudinal length measurement test method described below.
- the absorbent chassis 32 can also incorporate other materials that are designed primarily to receive, temporarily store, and/or transport liquid along the mutually facing surface with the absorbent core 44, thereby maximizing the overall absorbent capacity of the absorbent core 44, if desired.
- One suitable material is referred to as a surge layer (not shown), which may be positioned between the absorbent core 44 and the body side liner 42 to manage incoming fluid.
- the garment 20 with the absorbent chassis 32 has a saturated retention capacity of about 150 grams or greater, or about 250 grams or greater, or about 350 grams or greater, or about 450 grams or greater, or about 550 grams or greater.
- the saturated retention capacity of the garment 20 may be less than about 1500 grams.
- the saturated retention capacity of the garment 20 may be between about 250 grams and about 1000 grams. A test procedure for determining the saturated retention capacity is described in detail below.
- the garment 20 of the invention has been configured in a manner that reduces or eliminates drooping or sagging in the crotch region 26 by reducing the longitudinal length of the absorbent chassis 32 and, optionally, reducing the width of the crotch region 26. More specifically, the garment 20 of the invention has a longitudinal length of the absorbent chassis 32 that is proportional to one or more other dimensions of the absorbent chassis 32 in a manner that does not hold true for currently available commercial diapers. [0045] hi at least one embodiment, the absorbent garment 20 has a relatively low diaper length ratio (DLR). The DLR is the longitudinal length of the absorbent chassis 32 divided by the expanded width of the absorbent chassis measured between the distal edges 36 of the tabs 34.
- DLR diaper length ratio
- the DLR is an indication of the length of the garment in proportion to the overall size of the garment, with a lower DLR indicating a shorter length.
- the DLR is about 0.85 or less, or about 0.8 or less, or between about 0.6 and about 0.8.
- the absorbent garment 20 has a relatively low droop design ratio (DDR).
- the DDR is the longitudinal length of the absorbent chassis 32 multiplied by the width of the crotch region 26 and divided by the expanded width of the absorbent chassis measured between the distal edges 36 of the tabs 34.
- the DDR is the same as the DLR multiplied by the width of the crotch region 26.
- the DDR is an indication of both the length of the garment and the width of the crotch region in proportion to the overall size of the garment, with a lower DDR indicating a shorter length and/or a narrower crotch region.
- the DDR is about 150 mm or less, or about 145 mm or less, or about 140 mm or less, or about 135 mm or less, or about 130 mm or less, or more than about 100 mm, or between about 120 mm and about 140 mm.
- the absorbent garment 20 has a relatively low absorbent length design ratio (ALR).
- the ALR is the sum of the longitudinal length of the absorbent chassis 32 and the longitudinal length of the absorbent core 44, multiplied by the width of the crotch region 26 and divided by the expanded width of the absorbent chassis measured between the distal edges 36 of the tabs 34.
- the ALR differs from the DDR by accounting for the sum of the length of the absorbent chassis and the length of the absorbent core as a single length factor in the ratio.
- a lower ALR indicates a shorter total length of the garment plus the absorbent core and/or a narrower crotch region.
- the length of the absorbent core 44 does not have to be as long to deliver protection since the absorbent core fits higher up on the body when droop is absent.
- the ALR is about 280 mm or less, or about 275 mm or less, or about 270 mm or less, or about 260 mm or less, or about 250 mm or less, or about 240 mm or less, or between about 220 mm and about 250 mm.
- the absorbent garment of the invention may include one or more of the embodiments described herein. The Example below compares the dimensions of commercially available diapers with two samples of absorbent garments of the invention.
- the absorbent garment 20 includes a waist elastic member 56 in the front waist region 22, in the back waist region 24, or in both the front and back waist regions 22, 24 of the garment, operatively joined to the outer cover 40 and/or body side liner 42 and extending across part or a full length of the waist edges 38, 39.
- Waist elastic members are often included in absorbent garments, but because of poor retraction strength, the waist elastic members may fail to maintain the garment at the wearer's waistline.
- the waist elastic member 56 suitably has a retraction force of about 100 grams or greater, or about 150 grams or greater, or about 200 grams or greater, or about 250 grams or greater, or about 300 grams or greater, or less than about 1500 grams, or between about 200 and about 600 grams, when measured at 30% extension upon return from an extension of at least 50%.
- the test procedure for measuring retraction force is ASTM D2433 with minor modifications listed below.
- the diaper 20 may include also leg elastic members 58, as are known to those skilled in the art
- the leg elastic members 58 may be operatively joined to the outer cover 40 and/or body side liner 42 along opposite side edges of the absorbent chassis 32 and positioned in the crotch region 26 of the diaper 20.
- the waist elastic members 56 and the leg elastic members 58 can be formed of any suitable elastic material.
- suitable elastic materials include sheets, strands or ribbons of natural rubber, synthetic rubber, or thermoplastic elastomeric polymers. The elastic materials can be stretched and adhered to a substrate, adhered to a gathered substrate, or adhered to a substrate and then elasticized or shrunk, for example with the application of heat; such that elastic constrictive forces are imparted to the substrate.
- the waist elastic members 56 may include a polystyrene-polyethylene-polypropylene-polystyrene (SEPS) block copolymer, such as KRATON® G2760, available from Kraton Inc. of Houston, Texas, U.S.A.
- SEPS polystyrene-polyethylene-polypropylene-polystyrene
- KRATON® G2760 available from Kraton Inc. of Houston, Texas, U.S.A.
- the diaper 20 may be refastenable, thereby including a refastenable fastening system 60 (Fig. 1) for securing the diaper about the waist of the wearer.
- a suitable refastenable fastening system 60 may include fastening components 62, such as hook components, located along or adjacent to the distal edges 36 of the tabs 34.
- Suitable single-sided hook materials are available from Nelcro Industries B.N., Amsterdam, Netherlands, or affiliates thereof.
- the fastening components 62 are adapted to refastenably connect to mating fastening components 64, such as loop material, located on an outer surface of the front waist region 22.
- mating fastening components 64 such as loop material
- suitable loop material is "point unbonded" material. Point unbonded materials are fabrics having continuous thermally bonded areas defining a plurality of discrete unbonded areas and are described in greater detail in U.S. Patent No. 5,858,515 issued January 12, 1999 to Stokes, et al., incorporated herein by reference.
- the engaging elements of the fastening components 62 are adapted to repeatedly engage and disengage the engaging elements of the mating fastening components 64.
- the diaper 20 may include a pre-fastened, non-refastenable fastening system (not shown) to assist in applying the diaper 20 to a wearer.
- the non- refastenable fastening system may be torn when removing the diaper 20 from the wearer.
- the non-refastenable fastening system may be formed by attaching one edge of a loop material to a distal edge of the front waist region 22 of the absorbent chassis 32 and attaching an opposite edge of the same material to the tab 34 on the same side in the back waist region 24 of the garment with releasable bonds.
- the loop material may extend across a full width of the front waist region 22 of the absorbent chassis 32, thereby providing a mating fastening component 64, or landing strip, for the fastening components 62 of the refastenable fastening system 60, and extend even farther past the distal edges of the front waist region 22, such that the non-refastenable fastening system can be formed from the loop material that extends past the distal edges of the front waist region.
- the outer cover 40 desirably includes a material that may be substantially liquid impermeable or liquid permeable, and can be elastic, stretchable, extensible, non- stretchable, or non-extensible.
- the outer cover 40 can be a single layer of liquid impermeable material, but desirably includes a multi-layered laminate structure in which at least one of the layers is liquid impermeable.
- the outer cover 40 can include a liquid permeable outer layer and a liquid impermeable inner layer that are suitably joined together by a laminate adhesive (not shown).
- Suitable laminate adhesives which can be applied continuously or intermittently as beads, a spray, parallel swirls, or the like, can be obtained from Findley Adhesives, Inc., of Wauwatosa, Wisconsin, U.S.A., or from National Starch and Chemical Company, Bridgewater, New Jersey, U.S.A.
- the liquid permeable outer layer can be any suitable material and desirably one that provides a generally cloth-like texture.
- One example of such a material is a 20 gsm (grams per square meter) spunbond polypropylene nonwoven web.
- the outer layer may also be made of those materials of which liquid permeable body side liner 42 is made.
- the inner layer of the outer cover 40 can be both liquid and vapor impermeable, or can be liquid impermeable and vapor permeable.
- the inner layer of the outer cover 40 desirably includes a material that can be elastic, stretchable, extensible, non- stretchable, or non-extensible.
- the inner layer is desirably manufactured from a thin plastic film, although other flexible liquid impermeable materials may also be used.
- a suitable liquid impermeable film for use as a liquid impermeable inner layer, or a single layer liquid impermeable outer cover 40 is a 0.2 millimeter polyethylene film commercially available from Huntsman Packaging of Newport News, Virginia, U.S.A. If the outer cover 40 is a single layer of material, it can be embossed and/or matte finished to provide a more clothlike appearance. As earlier mentioned, the liquid impermeable material can permit vapors to escape from the interior of the disposable absorbent article, while still preventing liquids from passing through the outer cover 40.
- a suitable "breathable” material is composed of a microporous polymer film or a nonwoven fabric that has been coated or otherwise treated to impart a desired level of liquid impermeability.
- a suitable microporous film is a PMP-1 film material commercially available from Mitsui Toatsu Chemicals, Inc., Tokyo, Japan, or an XKO-8044 polyolefin film commercially available from 3M Company, Minneapolis, Minnesota.
- Certain "non-breathable" elastic films can also be used to make the outer cover 40.
- non-breathable films can be made of styrene-ethylene- butylene-styrene or styrene-isoprene-styrene block copolymers, KRATON® polymers from Kraton Inc. of Houston, Texas, U.S.A., metallocene catalyzed elastomers or plastomers, and the like.
- Other materials suitable for making the outer cover 40 include monolithic breathable films, such as those made of polyether amide based polymers, for example PEBAX, and ether/ester polyurethane thermal-plastic elastomers.
- the liquid permeable body side liner 42 is illustrated as overlying the outer cover 40 and absorbent core 44, and may but need not have the same dimensions as the outer cover 40.
- the body side liner 42 is desirably compliant, soft feeling, and non-irritating to the wearer's skin. Further, the body side liner 42 can be less hydrophilic than the absorbent core 44, to present a relatively dry surface to the wearer and permit liquid to readily penetrate through its thickness.
- the body side liner 42 desirably includes a material that can be elastic, stretchable, extensible, non-stretchable, or non-extensible.
- the body side liner 42 can be manufactured from a wide selection of web materials, such as synthetic fibers (for example, polyester or polypropylene fibers), natural fibers (for example, wood or cotton fibers), a combination of natural and synthetic fibers, porous foams, reticulated foams, apertured plastic films, or the like.
- synthetic fibers for example, polyester or polypropylene fibers
- natural fibers for example, wood or cotton fibers
- a combination of natural and synthetic fibers porous foams, reticulated foams, apertured plastic films, or the like.
- Various woven and nonwoven fabrics can be used for the body side liner 42.
- the body side liner can be composed of a meltblown or spunbonded web of polyolefin fibers.
- the body side liner can also be a bonded-carded web composed of natural and/or synthetic fibers.
- the body side liner can be composed of a substantially hydrophobic material, and the hydrophobic material can, optionally, be treated with a surfactant or otherwise processed to impart a desired level of wettability and hydrophilicity.
- the material can be surface treated with about 0.45 weight percent of a surfactant mixture including AHCOVEL® N-62 available from available from Uniqema Inc., a division of ICI of New Castle, Delaware, U.S.A. and GLUCOPON® 220UP available from Cognis Corporation of Ambler, Pennsylvania, and produced in Cincinnati, Ohio, in an active ratio of 3:1.
- the surfactant can be applied by any conventional means, such as spraying, printing, brush coating or the like.
- a suitable liquid permeable body side liner 42 is a nonwoven bicomponent web having a basis weight of about 27 gsm.
- the nonwoven bicomponent can be a spunbond bicomponent web, or a bonded carded bicomponent web.
- Suitable bicomponent staple fibers include a polyethylene/polypropylene bicomponent fiber available from CHISSO Corporation, Osaka, Japan. In this particular bicomponent fiber, the polypropylene forms the core and the polyethylene forms the sheath of the fiber.
- the chassis 32 may include a pair of containment flaps 46 which are configured to provide a barrier to the transverse flow of body exudates.
- a flap elastic member 54 (Fig.
- each containment flap 46 may be operatively joined with each containment flap 46 in any suitable manner as is well known in the art.
- the elasticized containment flaps 46 define an unattached edge which assumes an upright, generally perpendicular configuration in at least the crotch region 26 of the diaper 20 to form a seal against the wearer's body.
- the containment flaps 46 can be located along the transversely opposed side edges of the chassis 32, and can extend longitudinally along the entire length of the chassis or may only extend partially along the length of the chassis. Suitable constructions and arrangements for the containment flaps 46 are generally well known to those skilled in the art.
- the various components of the absorbent garment 20 can be integrally assembled together employing various types of suitable attachment means, such as adhesive, sonic and thermal bonds or combinations thereof.
- the resulting product is a garment that has a reduced likelihood of drooping in the crotch region.
- Test Methods Longitudinal Length Measurement Test Method [0062]
- the product (20) has an absorbent chassis length dimension measured between the front and back end edges (38 and 39) parallel to the longitudinal axis (48).
- the length dimensions of the product (20) are determined as follows.
- a suitable method for determining the longitudinal length of the absorbent chassis (32) and the absorbent core (44) is to hang the product vertically adjacent a flat, smooth, vertical surface.
- a suitable surface is a 0.25-inch thick acrylic plastic sheet available from Eagle Plastics and Supply of Appleton, Wisconsin.
- the product Prior to hanging, the product is opened by opening any fasteners, cutting or opening any side seams, and unfolding any folded portions to make the absorbent garment flat, as shown in the plan views of Figs. 2 and 3.
- Any elastic components that run the length of the chassis (such as leg elastics or elastics within containment flaps) are severed at least once per inch along their entire length.
- the product is hung with the back region (24) above the front region (22) and with the surface intended to face the wearer's outer garments during use positioned toward the flat, vertical surface.
- the top end margin of the product is held horizontal with two clamps, the inner edges of which are spaced 3.5 inches (8.9 cm) apart.
- the clamps are positioned adjacent the back waist edge 39 and, if possible, positioned to avoid any absorbent within the product, and are symmetrically disposed with respect to the longitudinal centerline/axis of the product. Any waist elastic present in the product is not stretched prior to securing the clamps.
- the lower end of the hanging product (front waistband region) is clamped with a jig weighing 250 g.
- the jig possesses two clamp units (medium size, Bulldog clips, 2- 1/8 inch) attached to a tie rod (0.25-inch - 20 x 12 inches, coarse thread, zinc plated), the clamps symmetrically placed with respect to the longitudinal centerline of the product, with a spacing between internal edges of the clamps of 3.5 inches (8.9 cm), with a 0.25-inch nut placed at the inner and outer edges of each clamp to hold the clamps in place.
- One (capped) bottle (1-ounce plastic screw cap bottle, such as NALGENE brand) is attached to each clamp with a piece of string. The assembly is placed on a laboratory balance and lead shot (No.
- the saturated retention capacity is a measure of the total absorbent capacity of the absorbent article.
- the saturated retention capacity is determined as follows. The absorbent garment to be tested, having a moisture content of less than about 7 weight percent, is weighed and then submerged in an excess quantity of room temperature (about 23 degrees Celsius) saline solution, described below. The garment is allowed to remain submerged for 20 minutes.
- the absorbent garment is removed from the saline solution and placed on a TEFLON® coated fiberglass screen having 0.25-inch openings (commercially available from Taconic Plastic Inc., Orlando, New York) which, in turn, is placed on a vacuum box and covered with a flexible rubber dam material.
- a vacuum of 3.5 kilopascals (0.5 pounds per square inch) is drawn in the vacuum box for a period of 5 minutes.
- the absorbent garment is weighed again. The amount of aqueous liquid retained by the absorbent garment is determined by subtracting the dry weight of the absorbent garment from the wet weight of the absorbent garment (after application of the vacuum) and is reported as the saturated retention capacity in grams of aqueous liquid retained.
- the saline solution is an aqueous solution of about 0.9 percent sodium chloride by weight.
- a suitable product is S/P® certified blood saline, commercially available from Baxter Diagnostics in Deerfield, Illinois.
- Retraction Force Test Method [0068] The test procedure for retraction force is ASTM D2433. Differences from this test procedure for testing waist retraction include: [0069] 1. Testing the entire product by placing the fasteners in the jaws of a Sintech 500/S, available from MTS Systems Corp. of Eden Prairie, Minnesota, U.S.A., such that the clamped product delivers a force of about 10 grams plus the weight of the product. [0070] 2. Cycling the sample to 50% extension twice. [0071] 3.
- the dimensions listed in Table 2 were used to calculate the proportions presented in Table 3.
- the proportions in Table 3 include the DLR, the DDR, and the ALR, as described in detail above, along with the ratio of retracted length of the absorbent chassis to extended width of the chassis as measured from tab-to-tab, and the ratio of the crotch width of the absorbent chassis to extended width of the chassis as measured from tab-to- tab.
- Garments 8 and 9 are the only two garments that fall within the scope of the invention.
- the retracted length of the garment is measured from the same points as the longitudinal length of the absorbent chassis, but with the elastic materials, such as the leg elastics, in a completely retracted state.
- the ratio of retracted length to extended width further illustrates the short length of the garment of the invention even when in a relaxed state.
- the ratio of crotch width to extended width further illustrates the narrowness of the crotch with respect to the overall size of the garment.
