Abstract

Reusable nappy pants for babies or incontinence sufferers consists of a flat material, which is a composite material (1-4). The composite material comprises two- or one-component hydrophilic-compact polyurethane that swells in water and/or microporous PUR; a polyurethane that does not swell or hardly swells in water; and a carrier (1).

Description

Die Erfindung bezieht sich auf eine wiederverwendbare, abwaschbare, waschfeste, atmungsaktive Windelhose für Kleinkinder und Inkontinenzpatienten, die aus wenigstens einem Zuschnitt eines Flachmateriales hergestellt ist, welches einerseits eine Nässesperre bildet und anderer­ seits wasserdampfdurchlässig sowie wasch- und reinigungs­ beständig ist.The invention relates to a reusable, washable, washable, breathable diaper pants for Infants and incontinence patients who are at least a blank of a flat material is produced, which on the one hand forms a moisture barrier and on the other partly permeable to water vapor as well as washing and cleaning is stable.

Bekanntlich haben sich zunehmend Wegwerf-Windelhosen auf Grund ihrer einfachen und hygienisch günstigen Handhabung beim Verbraucher durchgesetzt. Sie bereiten aber Probleme bezüglich der Entsorgung, der Deponierung und der Rückge­ winnung. Insbesondere die meist verwendeten Polyolefine für die Sicherung der Dichtheit der Windelhose lassen deren Kompostierung nicht zu. Da sich der Windelverbund außerdem nur schwer trennen läßt, ist eine wirtschaftlich vertretbare Rückgewinnung kaum möglich. So verbleibt nur die Lagerung auf Deponien oder die Verbrennung mit den bekannten Nachteilen für die Umwelt. Die Polyolefinfolie bildet außerdem eine Wasserdampfsperre, so daß der vom Träger abgesonderte Schweiß nicht entweichen kann. Die Haut des Trägers kann somit nicht ausreichend trans­ pirieren, wodurch unangenehme Hautreaktionen nicht aus­ zuschließen sind.As is well known, disposable diaper pants are increasingly on Because of their simple and hygienic handling enforced at the consumer. But they cause problems regarding disposal, landfill and return win. Especially the most used polyolefins to ensure the tightness of the diaper pants not composting them. Since the diaper composite difficult to separate, is economical reasonable recovery hardly possible. So only remains storage in landfills or incineration with the known environmental disadvantages. The polyolefin film also forms a water vapor barrier, so that from Separated sweat cannot escape from the wearer. The Skin of the wearer can therefore not be sufficiently trans pirate, which prevents unpleasant skin reactions are to be locked.

Wiederverwendbare Windelhosen sind bereits bekannt. Eine solche bekannte Windelhose ist zweiteilig ausgebildet und besteht aus der Windel-Überhose und aus der Windel-Unter­ hose. Die Windel-Überhose ist aus einem Flachmaterialzu­ schnitt aus Mikrofasermaterial hergestellt, welches einer­ seits wasserdampfdurchlässig ist und andererseits eine Nässesperre bildet, d. h. einen Nässedurchtritt nach außen verhindern soll. Reusable diaper pants are already known. A such known diaper pants is formed in two parts and consists of the diaper cover and the diaper bottom trousers. The diaper cover is made of a flat material cut made of microfiber material, which one on the one hand is permeable to water vapor and on the other hand one Moisture barrier forms, d. H. a passage of moisture to the outside should prevent.  

Die Windel-Unterhose besteht aus mehreren Lagen eines Materiales aus Naturfasern, wie Baumwolle o. dgl. Die Flachmaterialzuschnitte sind an den Konturen verbunden, wobei zwischen den Lagen und/oder auf der Innenseite der Windel-Unterhose, am Körper anliegend, saugfähige Einlagen aus Naturfasern vorgesehen sind (EP-PS 538 657).The diaper underpants consist of several layers of one Material made of natural fibers, such as cotton or the like Flat material blanks are connected to the contours, being between the layers and / or on the inside of the Diaper pants, close-fitting, absorbent pads made of natural fibers are provided (EP-PS 538 657).

Die bekannte Windelhose ist keine echte Alternative zu den Wegwerf-Windelhosen. Auf Grund der Zweiteilung beschränkt sich die Wiederverwendung auf die Windel-Überhose. Der Verbraucher wird seiner Gewohnheit folgend, die Windel- Unterhose als Wegwerfwindel oder -einlage behandeln, auch wenn sie für eine Wiederverwendung vorgesehen ist. Außerdem bildet die Windel-Überhose, bedingt durch ihre niedrige Druckfestigkeit von bestenfalls 1000 mm Wasser­ säule, keinen ausreichenden Schutz gegen einen Nässedurch­ schlag. Unter ungünstigen Bedingungen wird bei starken Körperbewegungen des Trägers im Liegen oder Sitzen der Körperdruck größer und auf die Windel übertragen. Übersteigt dieser Druck die Druckfestigkeit des Mikro­ fasermateriales der Windel-Überhose, ist insbesondere bei hohem Nässegehalt des saugfähigen Teiles der Windel ein Nässedurchschlag nach außen nicht zu vermeiden, was zur Verunreinigung der Sitz- oder Liegeflächen führt. Die Druckfestigkeit von 1000 mm Wassersäule des Mikrofaser­ materiales wird durch Behandlung mit Flour-Carbonharzen erreicht. Nachteilig ist, daß sich das Harz auswäscht, wodurch sich die Druckfestigkeit bei jedem Waschgang verringert, so daß die Gebrauchsdauer niedrig ist. Das Mikrofasermaterial ist zwar wasserdampfdurchlässig, jedoch wird der Grad der Wasserdampfdurchlässigkeit durch den Gesamtaufbau des Windelhosenverbundes bestimmt. Ihr relativ dicker Aufbau beeinträchtigt die Atmungsaktivität stark, so daß diesbezüglich kaum ein Unterschied zur Weg­ werf-Windelhose besteht. The well-known diaper pants are not a real alternative to the Disposable diaper pants. Limited due to the split reuse on the diaper covers. Of the Consumers will follow their habit of wearing diapers Treat underpants as a disposable diaper or insert, too if it is intended for reuse. In addition, the diaper covers, due to their low compressive strength of at best 1000 mm of water column, insufficient protection against moisture due to blow. Under unfavorable conditions, strong Body movements of the wearer when lying or sitting Body pressure larger and transferred to the diaper. If this pressure exceeds the compressive strength of the micro fiber material of the diaper overtrousers, is particularly at high moisture content of the absorbent part of the diaper Moisture penetration to the outside cannot be avoided, which leads to Contamination of the seating or lying surfaces leads. The Compressive strength of 1000 mm water column of the microfiber material is made by treatment with flour carbon resins reached. The disadvantage is that the resin washes out, which increases the compressive strength with every wash reduced so that the service life is low. The Microfiber material is permeable to water vapor, however is the degree of water vapor permeability through the Overall structure of the diaper pants composite determined. your relatively thick construction affects breathability strong, so that there is little difference to the way throwing diaper pants.  

Weiter ist nachteilig, daß die textile Oberfläche nur eine unzureichende Augenblicksreinigung zuläßt. Verschmutzungen können nur ungenügend beseitigt werden. Das ist besonders störend, wenn die Windelhose nicht sofort gewechselt werden kann, da Geruchsbelästigungen durch anhaftende Rückstände nicht auszuschließen sind.Another disadvantage is that the textile surface is only one allows inadequate instant cleaning. Pollution can only be removed insufficiently. It is special annoying if the diaper pants are not changed immediately can be, because odor nuisance by adhering Residues cannot be excluded.

Der Erfindung liegt das Problem zugrunde, wiederverwend­ bare Windelhosen bezüglich ihrer Handhabung den Ver­ brauchergewohnheiten besser anzupassen, den Wegwerfanteil zu senken, die Trageeigenschaften hinsichtlich des Nässe­ durchtrittes und der Wasserdampfdurchlässigkeit zu verbes­ sern und die Wasch- und Reinigungsbeständigkeit zu erhöhen. Dieses Problem wird durch die in den Patentan­ sprüchen genannten Merkmale gelöst. Die erfindungsgemäße Windelhose ist dadurch gekennzeichnet, daß das die Windel­ hose bildende Flachmaterial ein Verbundwerkstoff aus einem stark in Wasser quellenden, ein- oder zweikomponentigen, hydrophilen-compakten Polyurethan und/oder einem mikropo­ rösen Polyurethan, einem nicht oder kaum in Wasser quel­ lenden hydrophilen-compakten Polyurethan und einem Träger ist, mit einer Wasserdampfdurchlässigkeit nach DIN 53122 von mindestens 1500 g/qm/tag und einer Wasserdichte von mindestens 3500 mm Wassersäule.The problem underlying the invention is re-use bare diaper pants with regard to their handling Ver to better adapt consumer habits, the disposable portion to reduce the wearing properties with regard to moisture penetration and the water vapor permeability to verbes and the resistance to washing and cleaning increase. This problem is compounded by those in the patent characteristics mentioned resolved. The invention Diaper pants are characterized in that the diaper flat material forming a composite material from a strongly swelling in water, one or two component, hydrophilic compact polyurethane and / or a micropo rusty polyurethane, a little or no water lend hydrophilic compact polyurethane and a carrier with a water vapor permeability according to DIN 53122 of at least 1500 g / qm / day and a water resistance of at least 3500 mm water column.

Das Flachmaterial ist ein Verbundwerkstoff ausThe flat material is made of a composite material

  • - wenigstens einer Schicht (4) aus einem nicht oder kaum in Wasser quellendem, hydrophilen-compakten Polyurethan,- at least one layer ( 4 ) made of a hydrophilic-compact polyurethane which does not swell or hardly swells in water,
  • - wenigstens einer Schicht (3) aus mikroporösen Poly­ urethan oder stark in Wasser quellendem, hydrophilen­ compakten Polyurethan,- at least one layer ( 3 ) made of microporous polyurethane or strongly water-swelling, hydrophilic compact polyurethane,
  • - wenigstens einer Haftschicht (2) aus stark in Wasser quellendem, zweikomponentigen, hydrophilen-compakten Polyurethan und- At least one adhesive layer ( 2 ) made of water swelling, two-component, hydrophilic-compact polyurethane and
  • - einem Träger (1), der über die Schicht (2) mit den Schichten (3) und (4) flächig verbunden oder mit diesen punktverklebt ist.- A carrier ( 1 ) which is connected over the layer ( 2 ) to the layers ( 3 ) and ( 4 ) over the surface or is point-bonded to these.

Das Auflagegewicht der Schicht (4) beträgt 6 bis 10 g/qm, der Schicht (3) 25 bis 35 g/qm und der Schicht (2) 40 bis 50 g/qm.The coating weight of layer ( 4 ) is 6 to 10 g / m2, layer ( 3 ) 25 to 35 g / m2 and layer ( 2 ) 40 to 50 g / m2.

Ein weiteres Merkmal ist darin zu sehen, daß die Schich­ ten (3) und (4) mittels thermoplastischem, feuchtigkeits­ härtendem oder lösungsmittelhaltigen zweikomponentigem oder wäßrigem Polyurethan mit dem Träger punktverklebt sind. Der Träger ist ein textiles Gewebe, Gestricke, Vlies oder ein Koagulat.Another feature is that the layers ( 3 ) and ( 4 ) are point-bonded to the carrier by means of thermoplastic, moisture-curing or solvent-containing two-component or aqueous polyurethane. The carrier is a textile fabric, knitted fabric, fleece or a coagulate.

Die aus nicht oder kaum in Wasser quellende, hydrophile­ compakte Polyurethan-Schicht (4) bildet eine innere am Körper anliegende Seite der Windelhose und der Träger eine Außenseite derselben.The hydrophilic compact polyurethane layer ( 4 ), which does not swell or hardly swells in water, forms an inner side of the diaper pants that lies against the body and the wearer an outer side thereof.

Die mit der Erfindung erzielten Vorteile bestehen darin, daß sich der Wegwerfanteil auf die saugfähigen Einlagen, die von der Windelhose lösbar sind, beschränkt. Diese Einlagen sind kompostierbar und führen zur Entlastung der Deponien. Es können aber auch waschbare Einlagen Verwen­ dung finden. Die Handhabung entspricht weitgehend den Verbrauchergewohnheiten, da stark verschmutzte Einlagen wie üblich weggeworfen werden können und das Hosen innere hygienisch auf einfache Weise gesäubert werden kann, ohne diese jedesmal zu waschen.The advantages achieved by the invention are that the disposable portion relates to the absorbent pads, which are detachable from the diaper, limited. These Deposits are compostable and relieve the burden Landfills. Washable insoles can also be used find. The handling largely corresponds to that Consumer habits because of heavily soiled deposits can be thrown away as usual and the pants inside can be cleaned hygienically in a simple manner without wash them every time.

Durch die hohe Wasserdampfdurchlässigkeit und ihre hohe Druckfestigkeit werden bessere Trageeigenschaften erreicht, da die Haut des Trägers ausreichend transpi­ rieren kann und der Nässedurchschlag nach außen auch bei größeren Druckbelastungen sicher verhindert wird. Weitere Vorteile sind ihre Kochwaschbeständigkeit und ihre Abrieb­ festigkeit, wodurch eine relativ lange Gebrauchsdauer ge­ währleistet ist.Due to the high water vapor permeability and their high Compressive strength become better wearing properties achieved because the skin of the wearer sufficiently transpi and the moisture penetration to the outside larger pressure loads is reliably prevented. Further The advantages are their resistance to hot washing and their abrasion strength, resulting in a relatively long service life is guaranteed.

Nachstehend wird die Erfindung an Hand eines Ausführungs­ beispieles und von Zeichnungen näher erläutert. Die Zeichnungen zeigen inThe invention will now be described in terms of an embodiment example and explained in more detail by drawings. The Drawings show in

Fig. 1 einen flächenhaft verbundenen Werkstoff, Fig. 1 is a material surface-bonded,

Fig. 2 einen punktverklebten Werkstoff. Fig. 2 shows a point-glued material.

Die Windelhose (nicht gezeigt) wird in üblicherweise aus einem Flachmaterial zugeschnitten. Das Material wird ent­ lang der Konturen des Zuschnittes gegen Ausfasern einge­ säumt. Im Beinbereich werden Gummizüge und ein Auslauf­ schutz eingearbeitet und im Hüftbereich Klettverschlüsse oder andere geeignete Befestigungsmittel vorgesehen. Auf der Innenseite der Windelhose sind Halteschlaufen zur Aufnahme saugfähiger Einlagen angeordnet. Als saugfähige Einlagen können handelsübliche Wegwerf-Einlagen aus Zell­ stoff Verwendung finden, die leicht verrotten und damit kompostierbar sind. Es können aber auch kochfeste wieder­ verwendbare Einlagen verwendet werden.The diaper pants (not shown) are usually made from cut to a flat material. The material is ent along the contours of the cut against unraveling lines. In the leg area there are elastic bands and a run Protection incorporated and Velcro closures in the hip area or other suitable fasteners are provided. On There are holding straps on the inside of the diaper pants Absorbent pads arranged. As absorbent Deposits can be commercial disposable insoles made of cell Use fabric that rot easily and therefore are compostable. But it can also be boiled again usable insoles can be used.

Das Flachmaterial ist ein Verbundwerkstoff, der im wesentlichen aus Polyurethan-Schichten besteht. Der Träger 1 ist aus einem Polgewirke und bildet die Außen­ seite der Windelhose. Hierfür können aber auch andere textile Gewebe, Gestricke, Vlies oder ein Koagulat ein­ gesetzt werden.The flat material is a composite material that consists essentially of polyurethane layers. The carrier 1 is made of a pile knitted fabric and forms the outside of the diaper pants. However, other textile fabrics, knitted fabrics, fleece or a coagulum can also be used for this.

Nach Fig. 1 ist der Träger 1 mit mehreren Polyurethan- Schichten transfer beschichtet. Auf diese Weise ist der Träger 1 über die Haftschicht 2 mit den Schichten 3 und 4 flächig verbunden. Die Haftschicht 2 ist ein alipha­ tisches zweikomponenten Polyurethan, dessen Quell­ fähigkeit größer als 80% ist und eine hohe Wasser­ dampfdurchlässigkeit besitzt. Hierfür wird Ucecoat TD 9627/E verwendet. Statt dessen kann auch Ucecoat XDR 123 eingesetzt werden. Das Auflagegewicht beträgt 45 g/qm.According to Fig. 1, the support 1 is coated with several layers of polyurethane transfer. In this way, the carrier 1 is connected over the surface to the layers 3 and 4 via the adhesive layer 2 . The adhesive layer 2 is an aliphatic two-component polyurethane whose swellability is greater than 80% and has a high water vapor permeability. Ucecoat TD 9627 / E is used for this. Ucecoat XDR 123 can also be used instead. The coating weight is 45 g / qm.

Auf der Haftschicht 2 befindet sich die Schicht 3 aus einem mikroporösen Polyurethan, das durch Koagulation in situ hergestellt ist, wie beispielsweise Ucecoat 2000. Das Auflagegewicht beträgt 30 g/qm.On the adhesive layer 2 there is the layer 3 made of a microporous polyurethane, which is produced by coagulation in situ, such as Ucecoat 2000. The coating weight is 30 g / m2.

Über der mikroporösen Schicht 3 liegt die Schicht 4, die die Innenseite der Windelhose bildet. Diese Schicht ist aus nicht oder kaum in Wasser quellendem hydrophilen­ compakten Polyurethan, wie Ucecoat NPU 23, dessen Quellung kleiner als 10% ist. Die Schichtdicke beträgt etwa 6 m und das Auflagegewicht zirka 7 g/qm. Die Schicht 4 ist unempfindlich gegen Wasser und beein­ trächtigt die Wasserdampfdurchlässigkeit des Schicht­ nicht.Layer 4 , which forms the inside of the diaper pants, lies over the microporous layer 3 . This layer is made of non-or hardly water-swellable hydrophilic compact polyurethane, such as Ucecoat NPU 23, whose swelling is less than 10%. The layer thickness is about 6 m and the coating weight is about 7 g / sqm. Layer 4 is insensitive to water and does not impair the water vapor permeability of the layer.

Bei einer anderen Ausführung (Fig. 2) besteht der Träger 1 aus einem Koagulat und ist mit den Schichten 3 und 4 punkt- oder flächenverklebt. Die Verklebung erfolgt mit thermoplastischem, feuchtigkeitshärtendem Polyurethan. Es ist auch denkbar einen Verbundwerkstoff einzusetzen, bei dem die Schicht 3 aus hydrophilen-compakten Poly­ urethan, wie Ucecoat AB 7300 oder Impranil AH 03 ist.In another embodiment ( FIG. 2), the carrier 1 consists of a coagulate and is point or surface glued to the layers 3 and 4 . The bonding is done with thermoplastic, moisture-curing polyurethane. It is also conceivable to use a composite material in which the layer 3 is made of hydrophilic, compact polyurethane, such as Ucecoat AB 7300 or Impranil AH 03.
