Description

DISPOSABLE ABSORBENT ARTICLE THAT HAS A FECAL MANAGEMENT MEMBER FIELD OF THE INVENTION The present invention relates to articles that absorb and / or contain exudates from the body, including disposable absorbent articles such as diapers, incontinence products for adults, sanitary napkins and the like. More particularly the invention relates to disposable absorbent articles, which have the ability to retain low viscosity fiscal material away from the wearer's skin, in order to reduce leakage and make the user's cleaning easier, when the disposable article dirty is removed.
BACKGROUND OF THE INVENTION Disposable absorbent articles, such as diapers and adult incontinence products, are well known in the art. Said absorbent disposable articles collect and retain urine and fecal matter deposited thereon by the user. At present, many attempts in the art to handle urine and fecal matter collected and retained in the disposable absorbent article have been directed to the management of urine. In relation to the fecal matter collected by the disposable absorbent article, it is simply more difficult than the handling of the urine, due to the complex rheology of the low viscosity material. In the prior art several illustrative attempts are made to handle the urine to provide disposable absorbent articles having a first topsheet facing towards and contacting the wearer's body, and a secondary topsheet beneath the first topsheet, which both It absorbs urine, as it transfers urine to an underlying core for storage until the disposable absorbent items are removed from the user. Typically, the first topsheet and the topsheet have different material properties. The secondary topsheet may have a pore size smaller than the first topsheet, to assist in the transfer of urine through the topsheet. The first topsheet may be hydrophobic and more elastic when wetted than the secondary topsheet, in order to pass the fluids through the first topsheet towards the secondary topsheet. In yet another attempt in the prior art, the disposable absorbent article has a first topsheet, a secondary topsheet and a core. The secondary topsheet consists essentially of hydrophilic meltblown fibers and has a pore size greater than the pore size of the core. This arrangement supposedly allows the secondary upper sheet to rapidly receive multiple liquids and distribute the liquid in the X-Y plane before being absorbed by the core. In yet another attempt, the improved vertical penetration capacity for urine has been allegedly achieved by using inflated cellulose fibers, which are free of a surface finish or interlocked with each other. In another attempt in the prior art, an absorbent core suitable for acquiring and containing liquids such as urine, in a particularly effective efficient manner comprises multiple layers. The first layer, which is the one closest to the user, comprises a hydrophilic fibrous material and has an acquisition zone of a relatively lower average density than other portions of this layer, in order to quickly acquire the discarded liquids. Below the first layer there is a liquid handling layer comprising a high volume, low density, elastic material that is insensitive to moisture in order to rapidly acquire liquids by itself through the zone. of acquisition and distribute these liquids through the liquid handling layer to a storage layer. The storage layer comprises a combination of fibrous material and discrete particles of absorbent gelling material, and allows the liquid handling layer to be drained of the liquids it has acquired, so that the liquid handling layer can have a capacity of enough to acquire and distribute subsequent loads of liquids. Examples of such attempts in the prior art are included in the patents of E.U.A. 4,047,531 issued on September 13, 1977 to Karami; 4,798,603 issued January 17, 1989 to Meyer et al .; 5,037,409 issued August 6, 1991 to Chen et al .; 5,124,197 issued June 23, 1992 to Bernardín et al .; and 5,134,007 issued on June 28, 1992 to Reising and others. Of course, absorbent gelling materials are now well known in the art for their urinary handling ability. Absorbent gelling materials are polymeric materials capable of absorbing large amounts of fluids, such as urine, and retaining said fluids absorbed under moderate pressure. The effectiveness of the absorbent gelling materials is absolutely dependent on the shape, position and weight percentage of the absorbent gelling materials that are incorporated in the core of the disposable absorbent article. Recent attempts have been made in the art to provide absorbent gelling materials, which have the ability to swell against pressure. These teachings supposedly provide the advantage that absorbent materials absorb fluid under actual pressures exerted by the body during use. Still other teachings in the art provide absorbent gelling materials having a particular free swelling rate and absorbency under load. The alleged advantages of such absorbent gelling materials are lower bulk and volume with approximately the same absorbent capacity, the ability to rapidly absorb a discarded liquid under pressures typically encountered during use, and the ability to retain absorbent liquid under typically pressures. found during use. Examples of such attempts in the prior art include the patents of E.U.A. 5,147,343 issued September 15, 1992 to Kellenberg and 5,149.33 issued September 22, 1992 to Kellenberg et al. However, all these attempts to handle urine do little, if anything, to improve the handling of low viscosity fecal matter, which may also be present in the disposable absorbent article. Attempts to handle fecal matter include providing a first top sheet that closely conforms to the wearer and has an opening. The opening is optimistically recorded with the anal opening, so that the fecal material passes through it into a hollow space. The first topsheet may comprise several elastic panels in order to conform closely to the wearer's skin, and diagonal or be able to have linear elastic strands. Improvements have been made in this area of the prior art, such as optimizing the properties of the first top sheet material. Dich optimization makes the first topsheet more comfortable for the user allows a single disposable absorbent article to fit a large scale d sizes of users. Further attempts have been made in this area of the prior art to provide an absorbent core with a hole therein, in order to receive the fecal matter. The hole may have a flattened shape, so that it is larger and narrower than the opening in the first topsheet, or it may have the diamond shape. The hole in the core can be placed under an opening, which has elastic strips around its edges. Improvements for this type of disposable absorbent articles of the prior art include the addition of spacers. The spacers may be interposed between the first topsheet and the core, in order to ensure that a hollow space is present to receive the fecal material. Further attempts have been made in this prior art art to provide barriers that limit the movement of fecal matter to particular portions of the disposable absorbent article. The barriers limit the contact of the fecal matter with a smaller portion of the user's skin, than a disposable absorbent article with which it has no barriers. Still other attempts in the prior art provide fists for leg sweeping, straight from the anus of the upper sheet. The leg sweat cuffs prevent fecal matter from reaching the perimeter of the disposable absorbent article. Examples of such attempts to handle fecal matter include the US patent. 4,892,536 issued on January 9, 1990 to DesMarais; the patent of E.U.A. 4,908,803 issued on March 20, 1990 to Azíz et al .; the patent of E.U.A. 4,968,312 issued November 6, 1990 to Khan; patent of E.U.A. Commonly assigned 4,990,147 issued on February 5, 1991 to Freeland; patent of E.U.A. commonly assigned 5,037,416 issued August 6, 1991 to Alien et al .; patent of E.U.A. 5,062,840 issued November 5, 1991 to Holt et al .; patent of E.U.A. commonly assigned 5,171,236 issued December 15, 1992 to Dreier et al .; European Patent Application 0,355,740 A2 published on February 28, 1990 to Enloe. However, none of these attempts to handle fecal matter solved the problem of low viscosity fecal matter, which is important in very young children, particularly those who are being breastfed. The low viscosity fecal matter readily migrates into the disposable absorbent article under the influence of gravity and movement or pressure by the user. The migration of fecal matter usually moves it towards the perimeter of the disposable absorbent article, increasing the likelihood of leakage. The migration of the fecal matter also smears it against the user's skin, making cleaning more difficult. In order to clean the user, the caregiver must rub the entire area of the skin that has had contact with the stool and typically has to treat a relatively large stained area. An attempt in the prior art to handle low viscosity fecal matter is found in the patent application of E.U.A. series No. 08 / 076,713 filed on June 11, 1993 in the name of Roe. This application is a disposable absorbent article having a first top sheet with a high penetration of upper trans-sheet covering a secondary top sheet having a lower trans-sheet penetration. Accordingly, it is an object of this invention to provide a disposable absorbent article with which to reduce the leakage or leakage of fecal matter from the disposable absorbent article and to minimize the amount of low viscosity fecal matter on the wearer's skin once The disposable absorbent article is removed. Furthermore, an object of this invention is to provide a disposable absorbent article, which separates fecal matter into components.

In preferred embodiments, the backsheet 26 is impervious to liquids (eg, urine) and comprises a thin plastic film such as a thermoplastic film having a thickness of about 0.012 mm to about 0.051 mm. Suitable backsheet films include those manufactured by Tredegar Industries Inc. of Terre Haute, IN and sold under the trade names of X15305, X10962 and X10964. Other suitable backsheet materials may include breathable materials, which allow vapors to escape from the diaper 20, while still preventing exudates from passing through the backsheet 26. Illustrative breathable materials may include materials such as woven wefts, non-woven wefts, mixed materials such as non-woven wefts coated with film, and microporous films such as those manufactured by Mitsui Toatsu Co., or Japan under the designation ESPOIR NO and by EXXON Chemical Co., of Bay City, Tx, under the EXXAIRE designation. Suitable mixed breathable materials comprising polymer blends are obtained from Clopay Corporation Cincinnati, OH under the tradename HYTREL blend P 18-3097. Said breathable mixed materials are described in greater detail in PCT application No. WO 95/16746, published June 22, 1995 in the name of E.l, DuPont and patent application of E.U.A. copendiente series No. 08 / 744,487, filed on November 6, 1996 in the name of Curro. Other breathable backsheets that include non-woven webs and apertured films are described in U.S. Pat. No. 5,571,096 issued Dobrin et al. on November 5, 1996. Each one of these references is incorporated herein by reference in its entirety. The backsheet 26, or any portion thereof, may be elastically extensible in one or more directions. In one embodiment, backsheet 26 may comprise a film frame of structural elastic type ("SELF").
A web of structural elastic type film is an extensible material exhibiting an elastic type behavior in the direction of elongation, without the use of elastic aggregate materials. The SELF frame includes a deformable network having at least two distinct and contiguous regions. Preferably, one of the regions is configured so as to exhibit resistive forces in response to an axial elongation applied in a direction parallel to the predetermined axis before a substantial portion of the other region develops significant resistive forces to the applied elongation. At least one of the regions has a surface path length, which is greater than that of the other region as measured substantially parallel to the predetermined axis, while the material is in a non-taut condition. The region exhibiting the longest surface path length includes one or more deformations that extend beyond the piano of the other region. The SELF frame exhibits at least 2 significantly different stages from controlled resistive force to elongation along at least one predetermined axis when subjected to an elongation applied in a direction parallel to the predetermined axis. The SELF plot exhibits first resistive forces to the applied elongation until the elongation of the weft is sufficient to cause a substantial portion of the region having the longest path length to enter the plane of elongation applied, so that the SELF plot exhibits second resistive forces to the additional elongation. The total resistive forces to the elongation are greater than the first resistive forces to the elongation provided by the first region. SELF frames suitable for the present invention are described more fully in the U.S.A. No. 5,518,801, entitled "Web Materials Exhibiting Elastic-Like Behavior" (Frame Materials Exhibiting Elastic Type Behavior), issued to Chappell, et al on May 21, 1996, which is incorporated herein by reference. In alternative embodiments the backsheet 26 may comprise elastomeric films, foams, strands, or combinations of these or other suitable materials with non-woven or synthetic films. The backsheet 26 may be attached to the topsheet 24, the absorbent core 28, the fecal material handling member 29 or any other element of the diaper 20 through any joining means known in the art. For example, the joining means may include a uniform continuous layer of adhesive, a layer in patterns of adhesive, or an arrangement of separate lines, spirals, or adhesive spots. A preferred attachment means comprises an open-pattern network of filaments of adhesive as described in US Pat. 4,573,986 entitled "Disposable Waste-Containment Garment", (Disposable Waste Containment Garment), issued to Minetola et al. On March 4, 1986. Other suitable joining means include several adhesive filament lines, which are wound in a pattern spiral, as illustrated by the apparatus and methods shown in the US patent No. 3,911,173 issued to Sprague, Jr. on October 7, 1975; the patent of E.U.A. 4,785,995 issued to Ziecher et al. on November 22, 1978; and patent of E.U.A. 4,842,666 issued to Werenicz on June 27, 1989. Each of these patents is incorporated herein by reference. The adhesives that have been found to be satisfactory are manufactured by H.B. Fuller Company of St. Paul Minnesota and sold as HL-1258. Alternatively, the joining means may comprise thermal joints, pressure joints, ultrasonic joints, dynamic mechanical joints, or any other suitable joining means or combinations of these joining means as is known in the art. The topsheet 24 is preferably positioned adjacent the body surface 47 of the absorbent core 28 and may be attached thereto and / or to the backsheet 26 through any joining means known in the art. Suitable attachment means were described above with respect to the means for attaching the backsheet 26 to other elements of the diaper 20. In a preferred embodiment of the present invention, the topsheet 24 and the backsheet 26 are directly bonded together at some sites and are indirectly joined together at other sites by attaching them directly to other elements of the diaper 20. The topsheet 24 is preferably pleasant, of soft feel, and not irritant to the user's skin. In addition, at least a portion of the topsheet 24 is permeable to liquids, allowing liquids to easily penetrate through their thickness. A suitable top sheet 24 can be manufactured from a wide variety of materials, such as porous foams; cross-linked foams; plastic films with openings; another one more woven or non-woven of natural fibers (for example, wood or cotton fibers), synthetic fibers (for example, polyester or polypropylene fibers), or a combination of natural and synthetic fibers. If the absorbent assemblies include fibers, the fibers can be spin-spun, carded, wet-stretched, melt-blown, hydroentangled or otherwise processed as is known in the art. A suitable topsheet may also comprise openings, the openings preferably having a size of at least 0.2 mm2. A suitable top sheet 24 comprising a web of short length polypropylene fibers is manufactured by Veratec, Inc., a division of International Paper Company, of Walpole, Massachusetts under the designation P-8. The top sheets formed of suitable film are described in the U.S. patent.

No. 5,0069,394"Multilayer Polymeric Film" issued to Baird on April 9, 1991. Other sheets 30 are made in accordance with the patents of E.U.A.Nos. 4,609,518 and 4,629,643 issued to Curro et al. On September 2, 1986 and December 16, 1986, respectively, and both are incorporated herein by reference. Said films formed are available from The Procter & Gamble Company of Cincinnati, Ohio as "DRI-WEAVE" and Tredegar Corporation of Terre Haute, Indiana as "CLIFF-T". Preferably, the topsheet 24 is made of a hydrophobic material or is treated to be hydrophobic in order to isolate the user's skin from the liquids contained in the absorbent core 28. If the topsheet 24 is made of a hydrophobic material, preferably at least the upper surface of the topsheet 24 is treated to be hydrophilic so that liquids will be transferred through the topsheet more quickly. This decreases the likelihood that the body exudates will flow out of the topsheet 24 instead of being drawn through the topsheet 24 and absorbed by the absorbent core 28. The topsheet 24 can be made hydrophilic by treating it with a surfactant. or by incorporating a surfactant agent in the upper sheet. Suitable methods for treating the topsheet 24 with a surfactant include spraying the material of the topsheet 24 with the surfactant and immersing the material in the surfactant. A more detailed discussion of said treatment and hydrophilicity character is contained in the patent of E.U.A. No. 4,983,344 entitled "Absorbent Articles with Multiple Layer Absorbent Layers" (Absorbent Articles with Absorbent Layers of Multiple Layers) issued to Reising et al. on June 29, 1991; and patent of E.U.A. No. 4,988,345 entitled "Absorbent Articles with Rapid Acquiring Absorbent Cores" (Absorbent Articles with Rapid Acquisition Absorbent Nuclei), issued to Reising on January 29, 1991. A more detailed discussion of some suitable methods for incorporating surfactant into the topsheet can be found in U.S. Statutory Invention Registration No. H1670, published on July 1, 1997 in the names of Aziz et al. Each of these references is incorporated herein by reference. In another embodiment of the present invention, the topsheet 24 comprises the fecal material handling member 29. In this case, the fecal material handling member 29 may extend over the entire length of the topsheet or may extend only over regions of top sheet such as the rear waist region. Any portion of the topsheet 24 can be coated with a lotion as is known in the art. Examples of suitable lotions include those described in the US patent.

The topsheet may also include or be treated with antibacterial agents, some examples of which are described in PCT publication No. WO 95/24173 entitled "Absorbent Articles Containing Antibacterial Agents in the Topsheet for Odor Control" (Absorbent Articles Containing Antibacterial Agents in the Top Sheet for Odor Control) which was published on September 14, 1995 in the name of Jonson. In addition, the topsheet 24, the backsheet 26 or any portion of the topsheet or the backsheet may be embossed and / or have a matte finish to provide a clothing or fabric type appearance. The absorbent core 28 may contain any absorbent material that is generally compressible, conformable, non-irritating to the user's skin and capable of absorbing and retaining liquids such as urine, and other exudates from the body. The absorbent core 28 can be manufactured in a wide variety of sizes and shapes (eg, rectangular, hourglass-shaped, T-shaped, asymmetric, etc.) and can comprise a wide variety of liquid absorbent materials commonly used in disposable diapers and other absorbent articles such as crushed wood pulp, which is generally referred to as air felt. Examples of other suitable absorbent materials include curled cellulose wadding; meltblown polymers, including coform; chemically hardened, modified or interlaced cellulosic fibers; tissue paper including tissue paper wrappers and tissue paper laminates; absorbent foams; absorbent sponges; superabsorbent polymers; absorbent gelling materials, or any other known absorbent material or combination of materials. The configuration and construction of absorbent core 28 may also be varied (eg, the absorbent core or other absorbent structure may have zones of variable gauge, a hydrophilic gradient, a superabsorbent gradient, or a lower average density and weight acquisition zones lower average base, or may comprise one or more layers or structures). However, the total absorbent capacity of the absorbent core 28 must be compatible with the design load and intended use of diaper 20.

Each of these patents is incorporated herein by reference. Figure 2 illustrates a first embodiment of a fecal member according to the present invention, generally designated with the reference number 29. Generally, the fecal material handling member 29 is a sheet of loop material 128, having a backing 120 preferably comprising a thermoplastic backing layer 122 (eg, polypropylene) having front and rear major surfaces 123 and 124, and a multitude of longitudinally oriented fibers in a specially formed fiber sheet 126 having an anchor, generally portions of undeformed anchor 127 being embedded in the backing layer 122 in the separate elongation generally parallel to junction locations 128 that are continuous in a direction along the front surface 123 with arcuate portions 130 of the fiber sheet 126 projecting from the front surface 123 of the backing layer 122 between the joint locations 128 and the continuous rows also extending transversely through the sheet of bonded material 118. The arcuate portions 130 of the fiber sheet 126 comprise additional fibers 190 and have a generally uniform height of the backing layer 122 of more than about 0.5 millimeters and preferably greater than about 1.0 millimeter, the height of the fiber sheet 126 formed is at least one third, and preferably one half and one half of the distance between the bonding locations 128, the individual fibers in the fiber sheet 126 have a size of less than 25 denier (preferably on a scale of 1 to 10 denier), and the fiber sheet 126 without the backup layer 120 has a basis weight on the scale of 5 to 300 grams per square meter (and preferably on the scale of 15 to 100 grams per square meter) measured along the first surface 123 to provide a sufficient open area between the fibers in the fiber mine 126 along the arcuate portions 130 (i.e., between about 10 and 90% of the open area) to provide easy penetration of the fecal matter towards the individual fibers along the arcuate portions 130. The materials suitable for use as the backing layer 120 include, but are not limited to, thermoplastic films, porous films, apertured films, films formed with apertures, films formed without apertures, nonwoven webs, breathable materials, such as breathable films, including but not limited to microporous films, nonwoven webs with openings, canvases, and the like. The term "canvas" as used herein refers to a network of fibers or strands comprising at least two substantially parallel strands or fibers running in a first direction and at least two substantially parallel strands or fibers running in a second direction. . At least some of the fibers or strands running in the first direction are connected to at least some of the fibers or strands running in the second direction at the respective crossing points. The angle between the first and the second direction is at least 30 °, preferably 45 °, preferably 60 °, and most preferably 90 °. A canvas can comprise fibers or strands of different shapes, compositions and dimensions. Preferably, the backing layer is made of thermoplastic polymers. The backing layer 120 is preferably a relatively thin layer with a thickness in the scale of about 0.00125 to 0.025 centimeters. The additional fibers 190 are bonded to the fiber sheet 126 either by thermal bonding or by adhesive bonding. Suitable techniques for fixing the additional fibers 190 to the fiber sheet are by blowing the additional fibers onto the fiber sheet 128 in the molten state or by gathering the additional fibers 190 on the fiber sheet. The additional fibers 190 may be gathered or attached to the entire fiber sheet 126 or only to a portion of the fiber sheet 126, the portion comprising at least some of the arcuate portions 130. Preferably the length of the additional fibers 190 is less than the height of the arched portions 130 on the backrest. The basis weight of the additional fibers 190 may be homogeneous or may vary in different portions of the fiber sheet. Preferably, the basis weight of the additional fibers is between 1 g / m2 and 10 g / m2. Many different types of additional fibers 190 are suitable for use in the present invention. Suitable fibers 190 include natural fibers (modified or unmodified), as well as synthetically processed fibers. Examples of the modified / unmodified natural fibers include cotton, esparto, bagasse, hemp, flax, silk, wool, wood pulp, chemically modified wood pulp, jute, rayon, ethyl cellulose, and cellulose acetate. The synthetic fibers can be made from polyolefins such as polyethylene (for example PULPEX ™) or polypropylene, polyamides such as nylon, polyester such as DACRON ™ or KODEL ™, polyethylene terephthalate, polyvinyl chloride, polyvinyl fluoride, polytetrafluoroethylene, polyvinylidene, polyacrylics such as ORLON ™, polyvinyl acetate, polyethyl vinyl acetate, insoluble or soluble polyvinyl alcohol, polyurethanes, polystyrenes, and the like. The fibers included in the second component may comprise only natural fibers, only synthetic fibers, or any compatible combination of natural and synthetic fibers. Preferably, the additional fibers 190 are selected from the group of: polyester, polyamide, polyethylene, polypropylene, polyethylene terephthalate. These fibers have been widely used in faecal handling members because of their favorable combination of raw material properties such as elasticity and durability, their ease of conversion, and their cost, and the like. The fibers in the fiber sheet 126 can be arranged in several directions with respect to the parallel joining locations 128 and may or may not be joined together at crossing points in the arcuate portions 130.; they can be arranged in various directions with respect to the parallel joining locations 128 with most of the fibers in the fiber sheet 126 (i.e., over 80 or 90%) extending in directions at approximately a right angle to the locations binding 128; or all of the individual fibers in the fiber sheet 126 may extend in generally right-angled directions toward the generally parallel spaced apart 128 locations. The fiber sheet 126 preferably has a hydrophilic character, which is less than the hydrophilic character of the layer. rear 120. In a preferred embodiment, the fiber sheet itself has a gradient of hydrophilic character, wherein the arcuate portions 130 have a hydrophilic character which is less than the hydrophilic character of the joined locations 128. Still in this configuration, it is preferred that the attached locations 128 of the fiber sheet 126 have a hydrophilic character that is less than the hydrophilic character of the backing layer 120. Preferably, the fecal material handling member 29 is secured to the topsheet 24 at a very minimal degree to preserve the opening of the fecal material handling member 29 to allow the easy penetration of fecal material. Most preferably, the fecal material handling member 29 is not secured to the topsheet 24 while retaining the opening of the fecal material handling member 29 and also allowing the topsheet 24 to be separated from the fecal material handling member 29 creating a additional hollow space within the absorbent disposable article. However, it is recognized that the fecal material handling member 2 must be secured with the diaper 20 to prevent it from moving freely around it. Up to this point, it is preferred that the fecal material handling member 29 be secured directly to the underlying absorbent core 28. The fecal material handling member 29 can be attached to the absorbent core 28 through any attachment means known in the art. . For example, the joining means may include a uniform continuous layer of adhesive, a patterned layer of adhesive, or an arrangement in separate spiral lines or spots of adhesive. A preferred attachment means comprises an open-pattern network of filaments of adhesive as described in US Pat. 4,573,986, entitled "Disposable Waste-Containment Garment," issued to Minetola et al. On March 4, 1986. Other suitable bonding media include several lines of adhesive filaments, which are crimped at a spiral pattern, as illustrated by the apparatus and methods shown in the US patent 3,911, 173 issued to Sprague, Jr. on October 7, 1975; the patent of E.U. A. 4,785,996 issued to Ziecker et al. On November 22, 1978; and patent of E.U.A. 4,842,666 issued to Werenciz on June 27, 1989. Each of these patents is incorporated herein by reference. The adhesives that have been found to be satisfactory are manufactured by H. B. Fuller Company of St. Paul Minnesota and sold as HL-1258. Alternatively, the joining means may comprise heat bonds, pressure joints, ultrasonic joints, dynamic mechanical joints, or any other suitable joining means or combinations of these joining means as is known in the art. A particularly preferred binding means is an adhesive having a hydrophilic character, which is greater than the hydrophilic character of fiber sheet 126, most preferably a hydrophilic character which is also greater than the hydrophobic character of the backing layer 120. The arcuate portions of the fecal handling member of the present invention comprise a surface coating agent. As used herein, the term "surface coating agent" refers to any substance or composition that covers at least part of the surface of the arcuate portions of the fiber sheet. Preferably, the surface coating agent of the present invention is a composition containing silicone and / or an oil-containing composition. Other suitable surface coating agents include, but are not limited to, fluorinated materials, such as fluoropolymers (e.g., polytetrafluoroethylene (PTFE), commercially available under the tradename TEFLON ™), chlorofluoropoimers. Other materials that can prove to be suitable as a surface coating agent for the present invention include latex, paraffins, and the like. A silicone-containing composition suitable for the present invention is a silicone release coating available from Dow Corning of Midland. Michigan, USA, under the designation of Syl-Off 7677 to which is added an interlayer available as Syl-Off 7048, preferably in proportions of 100 parts to 10 parts, respectively. Another suitable silicon containing composition is a UV curable silicone comprising a mixture of two silicones commercially available from General Electric Company, Silicone Products Division, of Waterford, New York, USA, under the designations of UV 9300 or UV 9380C-D1, preferably in weight ratios of 100 parts to 2.5 parts, respectively. Examples of suitable oil-containing compositions include those described in U.S. Patent No. 5,607,760 entitled "Disposable Absorbent Article Having A Lotioned Topsheet Containing an Emoilient and a Poiyol Polyester Immobilizing Agent" which was issued for Roe et al. March 4, 1997; U.S. Patent No. 5,609,587 entitled "Diaper Having A Lotion Topsheet Comprising A Liquid Poiyol Polyester Emollient And An Immobilizing Agent" which was issued to Roe on March 11, 1997; U.S. Patent No. 5 635,121 entitled "Diaper Having A Lotioned Topsheet Containing A Polysiloxane Emollient" which was issued to Roe et al. on June 3, 1997; and U.S. Patent No. 5,643,588 entitled "Diaper Having A Lotioned Topsheet" which was issued to Roe et al. on July 1, 1997. The composition containing oil can also be extended in such a way that it is only released at the time of intended use such as being microencapsulated. The stool management member 29 is shown in Figure 1 positioned in the rear waist region 38 of the diaper 20. By placing the fecal material handling member 29 at least in the rear waist region 38, the limb fecal matter management 29 is aligned with the user's rectum, where it can be more effective in handling fecal material deposited on the diaper 20. However, the fecal material handling member 29 can be extended to the crotch region 37. The stool management member 29 also extends to the waist region 36 of the diaper 20. In some embodiments, it is also desirable that the stool management member 29 extend along the entire longitudinal dimension of the stool. diaper 20. In addition to placing the fecal material handling member 29 at least in the rear waist region 38, it is also desirable that the portion of the top sheet 24 placed within the waist region tra sera will have a sufficient open area to handle fecal material of low viscosity. To be more effective in handling low viscosity fecal matter, the fecal management member must have an open structure in elevation. A key component of this equation is the height of the arcuate portions 130 of the fiber sheet 126 from the backing layer 120. As mentioned above, the arcuate portions 130 of the fiber sheet 126 have a generally uniform height from the layer rear 120 of more than about 0.5 millimeters and preferably greater than about 1.0 millimeters. Although even higher heights can provide excellent handling of low viscosity fecal matter, for example, heights of 0.5 centimeters at such heights can create an unwanted volume in the diaper that can cause discomfort to the wearer. The other key component is the elasticity of the fecal handling member 29, more particularly the elasticity of the fiber sheet 126. In order to remain open, the fiber sheet 126 must have sufficient elasticity to withstand the packing forces and those applied by the user. Preferably the fiber sheet 126 has an elasticity of at least 50% after 30 seconds under an applied force of 100g / cm2, most preferably, the fiber sheet 126 has an elasticity of at least 75% after 30 seconds under an applied force of 100g / cm2, most preferably the fiber sheet 126 has an elasticity of at least 85% after 30 seconds under an applied force of 100g / cm2. The anchoring portions 127 preferably are of such dimension that a piano circle having a diameter of about 0.2 millimeters to about 20 millimeters can be inscribed thereon, most preferably, the anchor portions 127 are preferably of such dimension that a flat circle having a diameter of about 0.2 millimeters to about 10 millimeters can be inscribed thereon and preferably, the anchor portions 127 preferably are of such dimension that a flat circle having a diameter of about 0.2 millimeters to about 5 millimeters can be inscribed about them. Figure 3 illustrates a schematic side view of the embodiment of the stool handling member 29 of the present invention shown in Figure 2.
The fiber sheet 126 comprises additional fibers 190 which are attached to at least some of the arcuate portions 130 of the fecal material handling member. Figure 4 shows a schematic side view of a second embodiment of a stool handling member 29 of the present invention. The fiber sheet comprises additional fibers 190 which are attached to the fiber sheet 126. Figure 5 schematically shows a method and equipment for forming the fecal material handling member 29. The method illustrated in Figure 5 generally comprises forming polymer fibers longitudinally oriented to a fiber sheet 126, forming the fiber sheet 126, so that it has arcuate portions 130 projecting in the same direction from the generally parallel, spaced anchoring portions 127 of the fiber sheet 126, and joining the generally parallel parallel anchoring portions 127 of the fiber sheet 126 projecting from the front surface 123 of the backing layer 120. This method is performed by providing first and second hot corrugation members or rolls 226 and 227, each having an axis and including a plurality of generally axially extended flanges, circumferentially spaced apart , 228, around and defining its periphery, the ridges 228 having external surfaces and defining spaces between the flanges 228 adapted to receive the portions of the flanges 228 of the other corrugation member 226 and 227 in a coincident relationship with the fiber sheet 126 between the matching flanges 228 and to provide a roller coupling between the flanges 228 and spaces of the corrugation members in the shape of gear teeth. The corrugation members 226 and 227 are mounted in an axially parallel relationship with the portions of the flanges 228 of the corrugation members 226 and 227 generally coinciding in the shape of gear teeth; at least one of the corrugation members 226 or 227 is rotated; and the fiber sheet 126 is fed between the mating portions of the ridges 228 of the corrugation members 226 and 227 to generally form the fiber sheet 126 to the periphery of the first corrugation member 226 and form the arcuate portions 130 of the sheet of fibers 126 in the spaces between the flanges 228 of the first corrugation member 226 and the generally parallel anchoring portions of the fiber sheet 126 along the outer surfaces of the ridges 228 on the first corrugation member 226. The fiber sheet 126 formed is retained along the periphery of the first corrugation member 226, after it has been moved beyond the matching portions of the flanges 228. The thermoplastic backing layer 120 is formed and is attached to the anchoring portions 127 of the fiber sheet 126 on the end surfaces of the flanges 228 on the first corrugation member 226 by extruding the backing layer thermoplastic 120 (e.g., polypropylene) in a molten state from a die 240 toward a nozzle between the anchoring portions 127 of the fiber sheet 126 on the periphery of the first corrugating member 226 and a cooling roller 250, after which the fecal material handling member 29 is separated from the first corrugating member 226 and partially carried around the cooling roller 250 and through a nozzle between the cooling roller and a step roller 260 to complete the cooling and solidification of the thermoplastic backing layer 120. After leaving the drive roller 260, the surface coating agent 192 is applied to the arcuate portions 130 of the fiber sheet 126 through a surface coating device 190. Many suitable surface coating devices are known in the art., preferably the surface coating device selected from the roller coater, die coater, spray coater, graver coater, knife coater or slot orifice coater. The sheet of fibers 126 fed between the mating portions of the ridges 228 of the corrugation members 126 and 127 may be in the form of strands distributed such that the fibers in the fiber sheet 126 fed between the matching shoulders 228 of the members. The corrugation members 226 and 227 are uniformly distributed across the width of the fiber sheet 126 and extend generally perpendicular to the axes of the corrugation members 226 and 227, or the fibers in the fiber sheet 126 can be disposed in a random orientation as in a nonwoven web or sheet. Said non-woven sheet of randomly oriented fibers 126 without any internal bond except for the friction between the fibers, can be formed from loose fibers using a carding machine 270, as illustrated, said non-woven sheet of randomly oriented fibers 126 has sufficient integrity to be fed from the carding machine 270 to the nozzle between the corrugation members 226 and 227 (if necessary, a conveyor belt (not shown) can be provided to assist the support and guidance of the non-woven fiber sheet randomly oriented 126, preferably the first corrugation member 226 has a rough finish (e.g., formed from sand-sprinkling tooth), the second corrugation member 227 has a smooth polishing finish, and the first corrugation member 226 is heated to a temperature slightly above the temperature of the second corrugation member 226, so that the sheet of f preferably non-woven fibers 126 will remain along the surface of the first corrugating member 226 and will be brought towards the nozzle between the first corrugating member and the cooling roller 250 after passing through the nozzle between the corrugation members 226 and 227. The additional fibers are joined to at least the arcuate portions 130 of the fiber sheet 126 by means of the unit 290. A suitable unit 290 may be a unit that blows the additional fibers 190 onto the sheet of fiber. fibers 126. Alternatively, the unit 290 may be gathering the additional fibers 190 on the fiber sheet 126.
The corrugation members 226 and 227 adapted to have said fiber sheet 126 fed thereto may have their flanges 228 oriented generally in the range of 0 to 90 degrees with respect to their axes, but preferably have flanges 226 oriented at 0 degrees with with respect to (or parallel to) their axes which simplifies the manufacture of the corrugation members 226 and 227. Instead of extruding a solid thermoplastic sheet 120 from a die 240, a plurality of fibers of a die can be extruded to form a die. a backing layer, such as the backing layer 255 illustrated in Figure 4. Instead of extruding a thermoplastic material from a die such as a die 240, a non-cast backing layer may be used. The roller 250 is then heated for the thermal bonding of the backing layer to the fiber sheet. Instead of placing the unit 290 at the end of the process, it can also be placed before the formation of the arched portions 130 in the sheet fibers 126. Alternatively, the fiber sheet 126 can be formed from the fibers already comprising the additional fibers 190 when they are supplied to the process. Preferably, the actuators for the corrugation member 226 and 227 and for the cooling roller 250 are separately controllable, so that the cooling roller 250 can be rotated at a surface speed that is equal to, or different from, the surface velocity of the first corrugation member 226. When the cooling roller 250 and the first corrugation member 226 are rotated to have the same surface velocity, the fiber sheet 126 will have approximately the same shape along the length of the surface. the back layer 120 as that which it had along the periphery of the first corrugation member 226 as illustrated in figures 2 to 5. When the cooling roll 250 and the first corrugation member 226 are rotated so that the The cooling roller has a surface velocity that is less than the surface velocity of the first corrugation member 226, the anchor portions 127 d. The fiber sheet 126 will be moved closer in the backing layer 120 in the nozzle between the cooling roller 250 and the first corrugation member 226, resulting in a higher density of the linker portions 130 along the back layer 120 that when the cooling roller 250 and the first corrugation member 226 are rotated so as to have the same surface velocity. This technique for increasing the number of linker portions 130 or the link population is useful both for making fecal handling members having different numbers of linker portions 130 per centimeter of backup length using the same type, as for making managing members. of fecal matter with more bound portions 130 po centimeter of the back length that can be formed between the ridges 228 machined on the corrugation member 226 and 227 due to the physical limitations in the machining of said ridges 228 very closely. The diaper 20 may also comprise at least one elastic waist feature 34 that helps provide improved fit and containment. The elastic waist feature 34 is generally adapted to elastically expand and contract to dynamically fix the wearer's waist. The elastic waist feature 34 preferably extends at least longitudinally outward from at least one waist edge 62 of the absorbent core and generally forms at least a portion of the outer edge 52 of the diaper 20. In general, disposable diapers are constructed in order to have two elastic waist feature, one placed in the first waist region 36 and one positioned in the second waist region 38. In addition, although the elastic waist feature 34 or any of its constituent elements may comprise one or more separate elements fixed to the diaper 20, the elastic waist feature 34 can be constructed as an extension of other elements of the diaper 20, such as the backsheet 26, the topsheet 24 or both the backsheet 26 and the top sheet 24. The elastic waist feature 34 can be constructed in a number of different configurations, including those described in the US patent 4,515,595 issued to Kievit and others on May 7, 1985; the patent of E.U.A. 4,710,189 issued to Lash on December 1, 1987; the patent of E.U.A. No. 5,151,092 issued to Buell on September 9, 1992; and the patent of E.U.A. No. 5,221, 274 issued to Buell on June 22, 1993.
