Abstract
Description
Die Erfindung betrifft ein elastisches Laminat mit einer textilen Oberfläche, ein Herstellungsverfahren sowie ein Bandmaterial, eine Rolle, ein Windelverschlussband und eine Windel, jeweils mit einem elastischen Laminat mit textiler Oberfläche.The The invention relates to an elastic laminate having a textile surface Manufacturing process and a strip material, a roll, a diaper closure tape and a diaper, each with a flexible laminate with textile Surface.
Um ein elastisches Laminat mit einem textilen haptischen Charakter an der Oberfläche zu erzeugen, wird herkömmlich ein – meist kardiertes – Vlies an der Außenschicht einer elastischen Folie angeordnet. Hierzu werden dort Fasern, meist aus Polypropylen (PP), mit Klebstoff befestigt.Around an elastic laminate with a textile haptic character on the surface to produce, becomes conventional one - mostly carded fleece on the outer layer an elastic film arranged. For this purpose, there are fibers, mostly made of polypropylene (PP), fixed with adhesive.
Ein technisches Einsatzgebiet eines solchen Laminats liegt in der Verwendung als Teil eines Windelverschlussbandes. Insbesondere Babywindeln, aber auch Inkontinenzwindeln, erfordern für einen bestmöglichen Sitz am Körper eine Elastizität der Verschlussbänder. Dabei ist aus Gründen des Tragekomforts eine textile Haptik an der Oberfläche gewünscht.One technical application of such a laminate is in use as part of a diaper fastening tape. Especially baby diapers, but also incontinence diapers, require for the best possible Seat on the body an elasticity the fastener tapes. It is for reasons the wearing comfort desired a textile feel on the surface.
Bei den herkömmlichen Herstellungsmethoden sind nachteilhaft mehrere Arbeitsgänge erforderlich. Außerdem besteht zwischen dem elastischen Träger über den Kleber und die Außenschicht oft nur eine schlechte Verbundfestigkeit. Hinzu kommt, dass die Oberfläche oft nur verhalten flauschig ist.at the conventional one Manufacturing methods are disadvantageously several operations required. Furthermore exists between the elastic carrier over the adhesive and the outer layer often only a poor bond strength. In addition, the surface often only fluffy is behaving.
Der Erfindung liegt die Aufgabe zugrunde, einen elastischen flauschigen Verbund zur Verfügung zu stellen, der gut verarbeitbar ist.Of the Invention is based on the object, an elastic fluffy Verbund available too which is easy to process.
Nach einem ersten Aspekt der Erfindung löst diese Aufgabe ein elastisches Laminat mit einem elastischen Träger und einer textilen Oberfläche, wobei die textile Oberfläche zwei unterschiedliche Faserscharen aufweist.To In a first aspect of the invention this object solves an elastic Laminate with an elastic support and a textile surface, the textile surface has two different fiber bundles.
Durch das Verwenden mehrerer unterschiedlicher Faserarten, die jeweils als Schar im Wesentlichen identischer Fasern vorliegen, können die Gesamteigenschaften des Faserverbundes sehr individuell an bestimmte Erfordernisse und Aufgaben angepasst werden. Dabei können die Unterschiede zwischen den Faserscharen insbesondere in einer anderen Formgebung liegen, beispielsweise in Unterschieden der Länge, der Dicke, der Querschnittsform und/oder der Texturierung. Alternativ und kumulativ können sich die Faserscharen im Werkstoff unterscheiden. Auch sind Konstellationen denkbar, in denen sich die Fasern zweier Scharen in einem Merkmal, beispielsweise des Werkstoffs, unterscheiden, während die Schar des ersten Werkstoffs und/oder die Schar des zweiten Werkstoffs noch in sich weiter variiert, beispielsweise dahingehend, dass noch unterschiedliche Faserlängen vorhanden sind. Eine solche Konstellation wird sich auch bei Benutzung eines Laminats ergeben, bei welchem zunächst die Fasern einer Schar alle dieselbe Länge haben, wenn zumindest ein Teil der Fasern infolge mechanischer Belastung bricht oder reißt.By using several different fiber types, respectively as a family of substantially identical fibers, the overall properties the fiber composite very individual to specific requirements and Tasks are adjusted. The differences between the fiber bundles are in particular in a different shape, for example, in differences of length, thickness, cross-sectional shape and / or the texturing. Alternatively and cumulatively, the fiber bundles can differ in the material. Also, constellations are conceivable in which the fibers of two coats in a feature, for example of the material, while different the family of the first material and / or the family of the second material still varies in itself, for example, to the effect that still different fiber lengths available. Such a constellation will also be in use a laminate in which initially the fibers of a crowd all the same length have, if at least some of the fibers due to mechanical stress breaks or tears.
Die Erfindung nutzt dabei die Erkenntnis, dass den verschiedenen Faserscharen eine Aufgabenteilung zugeordnet werden kann, beispielsweise dahingehend, dass eine erste Faserschar überwiegend den Verbund mit dem Träger bewirkt, während die zweite Faserschar überwiegend die Oberflächeneigenschaften des Laminats bestimmt. Durch eine geeignete Auswahl der Faserscharen und gegebenenfalls ein geeignetes Auftragverfahren der Fasern auf den Träger zu einem Vliesstoff ermöglicht die Erfindung das gezielte Herstellen von elastischen Laminaten mit textiler Oberfläche, welche die an sie gestellten Aufgabenstellungen in bislang nicht gekannter Weise erfüllen.The The invention uses the knowledge that the different fiber bundles a task sharing can be assigned, for example, to that a first group of fibers predominantly the bond with the carrier causes while the second group of fibers predominantly the surface properties of the laminate. By a suitable selection of fiber bundles and optionally, a suitable application method of the fibers the carrier allows for a nonwoven fabric the invention the targeted production of elastic laminates with textile surface, which the tasks put to them in so far not meet the known manner.
Wenn schwerpunktmäßig zwei Aufgaben für das herzustellende Laminat identifiziert werden, nämlich beispielsweise Verbundfestigkeit am elastischen Träger und Flauschigkeit der Oberfläche, ist es von Vorteil, genau zwei unterschiedliche Faserscharen am Träger vorzusehen, wobei die beiden Faserscharen jeweils schwerpunktmäßig eine der beiden Hauptaufgaben lösten.If mainly two Tasks for that to be produced laminate, namely, for example, bond strength on the elastic carrier and fluffiness of the surface, it is advantageous to have exactly two different fiber bundles on carrier provide, with the two fiber bundles each a focus solved the two main tasks.
Wie bereits erläutert wurde, kann sich eine vorteilhafte Konstellation einstellen, wenn überwiegend eine erste Faserschar unmittelbar mit dem elastischen Träger verbunden ist. Bei geeigneter Auslegung der ersten Faserschar zum Herstellen des Verbunds mit dem elastischen Träger, beispielsweise hinsichtlich der Werkstoffwahl, lassen sich hier hervorragende Ergebnisse erzielen. So eignet sich für ein elastisches Laminat, welches in einem Windelverschlussband eingesetzt werden soll, besonders Polyethy len (PE) für einen thermischen Verbund mit dem Träger. Gleichzeitig setzen PE-Fasern die Dehnbarkeit des elastischen Trägers auf ein Maß, welches gerade für den Einsatz in Windelverschlussbändern sehr geeignet ist. Auch kann das Laminat mit PE-Fasern als mit dem Träger verbundene Faserschar auch hohe Kräfte mühelos aufnehmen.As already explained a favorable constellation can arise, if predominantly a first fiber bundle directly connected to the elastic carrier is. With a suitable design of the first fiber share for manufacturing of the composite with the elastic support, for example with regard to the choice of material, excellent results can be achieved here. So is suitable for a elastic laminate used in a diaper fastening tape is to be used, especially Polyethy len (PE) for a thermal bond with the carrier. At the same time PE fibers put on the elasticity of the elastic carrier a measure of which especially for the use in diaper fastener tapes very suitable. Also, the laminate with PE fibers than with the carrier Connected group of fibers also effortlessly absorb high forces.
In einer bevorzugten Ausführungsform des elastischen Laminats sind zumindest nahezu ausschließlich Fasern der ersten Faserschar unmittelbar mit dem elastischen Träger verbunden. Hierdurch wird eine Aufgabenteilung in sehr scharfem Maße möglich.In a preferred embodiment the elastic laminate are at least almost exclusively fibers the first fiber bundle directly connected to the elastic carrier. As a result, a division of tasks is possible to a very sharp extent.
Wenn die erste Faserschar zumindest überwiegend in Verbund mit dem elastischen Träger steht, wird vorgeschlagen, dass die zweite Faserschar eine äußere Grenzschicht mit der ersten Faserschar formt. Der Verbindungsbereich der ersten Faserschar mit dem elastischen Träger bildet eine innere Grenzschicht. Dabei können die Fasern der ersten Faserschar beispielsweise eine bestimmte Strecke, somit die Tiefe der Grenzschicht, in das elastische Laminat eingedrungen sein. Auch ist möglich, dass die Fasern der ersten Faserschar ausschließlich an der Oberfläche des elastischen Trägers anhaften. In diesem Falle liegt die innere Grenzschicht mit nur sehr geringer Tiefe an der Oberfläche des elastischen Trägers vor. Wenn die Fasern der zweiten Faserschar mit den Fasern der ersten Faserschar die äußere Grenzschicht formen, liegt diese zumindest im ganz Wesentlichen außerhalb des elastischen Trägers. In der äußeren Grenzschicht sind ausschließlich Verbindungen zwischen den Fasern, dabei insbesonde re zwischen den Fasern der beiden verschiedenen Scharen, vorhanden. Eine solche Anordnung orientiert die zweite Faserschar schwerpunktmäßig zur Oberfläche des Laminats hin, während die erste Schar schwerpunktmäßig zum Träger orientiert istWhen the first fiber bundle at least predominantly in association with the elastic carrier it is proposed that the second fiber bundle forms an outer boundary layer with the first fiber bundle. The connecting region of the first fiber bundle with the elastic carrier forms an inner boundary layer. In this case, the fibers of the first fiber bundle, for example, a certain distance, thus the depth of the boundary layer, have penetrated into the elastic laminate. It is also possible that the fibers of the first fiber bundle adhere exclusively to the surface of the elastic carrier. In this case, the inner boundary layer is present at the surface of the elastic support with only a very small depth. When the fibers of the second fiber bundle with the fibers of the first fiber bundle form the outer boundary layer, this is at least substantially outside the elastic support. In the outer boundary layer only connections between the fibers, while insbesonde re between the fibers of the two different flocks available. Such an arrangement orients the second fiber bundle primarily toward the surface of the laminate, while the first share is oriented primarily toward the carrier
Es sei darauf hingewiesen, dass sich die äußere Grenzschicht auch bis zur Oberfläche des Laminats erstrecken kann. In diesem Falle wird die Oberfläche durch Fasern beider Faserscharen gebildet, wobei je nach Faserwahl diese dort zu gleichen oder ungleichen Teilen vorliegen können. Üblicherweise wird jedoch in der äußeren Grenzschicht ein Übergang von der ersten Faserschar zur zweiten Faserschar erfolgen.It It should be noted that the outer boundary layer also up to the surface of the laminate can extend. In this case, the surface gets through Fibers of both fiber bundles formed, depending on the fiber choice this can be there in equal or unequal parts. Usually will however, in the outer boundary layer a transition take place from the first fiber share to the second fiber share.
Alternativ ist es jedoch denkbar, dass beide Faserscharen gleichmäßig in der textilen Oberfläche verteilt sind, sodass insbesondere Fasern jeder Faserschar jeweils an die Oberfläche gelangen.alternative However, it is conceivable that both fiber bundles evenly in the distributed textile surface are, so in particular fibers each fiber group each to the surface reach.
Es wurde bereits vorstehend erläutert, dass sich insbesondere für ein Band, welches an einem Windelverschlussband angewendet werden soll, Polyethylen zum Herstellen des Verbundes mit dem elastischen Träger und somit als erste Faserschar hervorragend eignet. Unabhängig hiervon wird jedoch vorgeschlagen, dass die Faserscharen unterschiedliche Polymere aufweisen. Polymere sind in ihrer Eigenschaft als Kunstfasern kostengünstig herstellbar und gut zu einem elastischen Laminat nach der Erfindung verarbeitbar.It has already been explained above, that in particular for a tape which is applied to a diaper fastening tape polyethylene, for making the composite with the elastic carrier and thus as a first fiber share excellent. Independent of this However, it is proposed that the fiber bundles different Have polymers. Polymers are in their capacity as synthetic fibers economical manufacturable and good to an elastic laminate according to the invention processable.
Neben Polyethylen ist auch Polypropylen ein gut geeigneter Werkstoff zum Verarbeiten in einer der Faserscharen. Wenn die Oberfläche des Laminats ein großes Maß an Polypropylen-Fasern oder einer Mischung aus Polypropylen- und Polyethylen-Fasern aufweist, ergibt sich dort eine beachtliche Erhöhung der Flauschigkeit. Das Polyethylen ist – wie bereits erläutert – insbesondere dazu geeignet, eine dauerhafte Verbindung zwischen der elastischen Trägerlage und den Polypropylen-Fasern herzustellen. Reines Polypropylen beispielsweise lässt sich insbesondere thermisch nur sehr schlecht anbinden.Next Polyethylene is also a good suitable material for polypropylene Processing in one of the fiber bundles. If the surface of the Laminate a big one Measure Having polypropylene fibers or a blend of polypropylene and polyethylene fibers, There is a considerable increase in fluffiness there. The Polyethylene is - like already explained - in particular suitable for a permanent connection between the elastic support layer and produce the polypropylene fibers. Pure polypropylene, for example let yourself especially thermally bond very poorly.
Unabhängig von der Werkstoffwahl der beiden Faserscharen wird vorgeschlagen, dass zumindest eine Faserschar texturierte Fasern aufweist. Texturierte Fasern, also solche mit einer Oberfläche, die von einer glatten vor allem gebogenen Zylinderform abweichen, bieten nicht nur den Vorteil, dass sie beim Kardieren leicht zu händeln sind. Sie gehen auch sehr stabile Verbunde mit benachbarten Fasern ein. Dies ist insbesondere dann von Vorteil, wenn die Faserscharen auf dem Träger einen Vliesstoff bilden.Independent of the choice of material of the two fiber bundles is proposed that at least one fiber bundle has textured fibers. textured Fibers, ie those with a surface that are smooth especially curved cylinder shape, not only provide the Advantage that they are easy to handle while carding. They go too very stable composites with adjacent fibers. This is special then advantageous if the fiber bundles on the carrier a Form nonwoven fabric.
Um die Produktion möglichst kostengünstig zu halten und um ein mögliches Herauslösen eines Drittstoffs zu vermeiden, wird vorgeschlagen, dass das Laminat klebstofffrei ausgeführt ist. Es wurde bereits erläutert, dass zumindest eine der beiden Faserscharen den Verbund zum elastischen Träger herstellen kann und dass die beiden Faserscharen miteinander verbunden sein können, so dass ein Klebstoff nicht benötigt wird.Around the production as possible inexpensive too hold and a possible leaching to avoid a third party, it is suggested that the laminate executed adhesive-free is. It has already been explained that at least one of the two fiber bundles the composite to the elastic carrier can make and that the two fiber coulters connected together could be, so that an adhesive is not needed becomes.
Für eine besonders angenehme Haptik können beide Oberflächen des Laminats textil ausgestaltet sein.For a special pleasant feel both surfaces be configured of the laminate textile.
Nach einem zweiten Aspekt der Erfindung löst die Aufgabe ein Verfahren zum Herstellen eines elastischen Laminats mit einem elastischen Träger und einer textilen Oberfläche, wobei eine erste Faserschar mit dem Träger verbunden wird und eine zweite Faserschar mit dem Träger und/oder mit der ersten Schar untereinander verbunden wird. Ein solches Herstellungsverfahren ergibt unmittelbar ein elastisches Laminat wie nach dem ersten Erfindungsaspekt beschrieben.To In a second aspect of the invention, the object solves a method for producing an elastic laminate with an elastic Carrier and a textile surface, wherein a first fiber bundle is connected to the carrier and a second Fiber bundle with the carrier and / or with the first group is interconnected. One such manufacturing process immediately gives an elastic Laminate as described according to the first aspect of the invention.
Um die Produktion möglichst kostengünstig zu halten, wird vorgeschlagen, dass die Verbindungen zwischen dem elastischen Träger und den Faserscharen bzw. zwischen den Faserscharen untereinander in einem Arbeitsgang hergestellt werden, bevorzugt nachdem die erste und die zweite Faserschar im Kardierprozess miteinander vermischt worden sind.Around the production as possible inexpensive too hold, it is suggested that the connections between the elastic carrier and the fiber bundles or between the fiber bundles with each other be prepared in one operation, preferably after the first and the second fiber bundle in the carding process mixed together have been.
Dabei kann der elastische Träger insbesondere aus einem thermoplastischen Elastomer extrudiert werden. Auf diese Weise können leicht lange Bänder hergestellt werden. Beispielsweise bei der Verwendung als Teil eines Windelverschlussbandes ist dies von großem Nutzen.there can the elastic carrier be extruded in particular from a thermoplastic elastomer. That way you can slightly long ribbons getting produced. For example, when used as part of a Diaper fastening tape is of great use.
Wenn der Träger heiß extrudiert wird, können die Faserscharen leicht auf den Träger aufkaschiert werden, während der Träger noch erwärmt ist. Auf diese Weise entfällt ein weiteres Erwärmen, und dennoch können die Fasern zumindest einer Faserschar einen innigen Verbund mit dem elastischen Trägermaterial eingehen.When the carrier is hot extruded, the fiber bundles can be easily laminated to the carrier while the carrier is still heated. In this way, eliminates further heating, and yet the fibers of at least one fiber group can form an intimate bond with the elastic support material.
Mit einem Verfahren nach dem zweiten Erfindungsaspekt kann insbesondere ein elastisches Laminat nach dem ersten Erfindungsaspekt hergestellt werden. Dies ist unmittelbar ersichtlich.With A method according to the second aspect of the invention can in particular an elastic laminate according to the first aspect of the invention are produced. This is immediately apparent.
Ein elastisches Laminat nach dem ersten Erfindungsaspekt kann besonders vorteilhaft bei der Herstellung eines Bandmaterials mit einem elastischen Abschnitt eingesetzt werden, wobei gerade der elastische Abschnitt ein solches Laminat aufweist. Beispielsweise kann das ausgeprägte elastische erfindungsgemäße Laminat an zwei im Wesentlichen inelastischen Bandstücken befestigt sein. Hierdurch ergibt sich eine Elastizität des Gesamtbandmaterials, wobei für die im Wesentlichen inelastischen Bandstücken eine freie Werkstoffwahl herrscht. Der Anschluss kann beispielsweise mit Klebstoff hergestellt sein.One elastic laminate according to the first aspect of the invention can be particularly advantageous in the production of a strip material with an elastic Be inserted section, where just the elastic section has such a laminate. For example, the pronounced elastic laminate according to the invention be attached to two substantially inelastic band pieces. hereby results in an elasticity of the total band material, wherein for the substantially inelastic band pieces a free choice of material prevails. The connection can be made for example with adhesive.
Ein solches Bandmaterial wird bevorzugt zu einer Rolle aufgewickelt, wenn es zur Weiterverarbeitung bereitgestellt wird.One such strip material is preferably wound into a roll, when it is provided for further processing.
