Description

Mehrlagiges textiles Gebilde Multi-layer textile structure
Die Erfindung betrifft ein mehrlagiges textiles Gebilde, umfassend zwei textile Oberschichten, wobei zwischen den beiden Oberschichten zumindest eine textile Mittelschicht angeordnet ist. The invention relates to a multi-layer textile structure comprising two textile upper layers, at least one textile middle layer being arranged between the two upper layers.
Derartige textile Flächengebilde sind beispielsweise aus der DE 20 2008 016 926 U1 und der DE 10 2004 024 134 A1 bekannt. DE 20 2008 016 926 U1 zeigt ein Zellstofftuch, bestehend aus einer Faserschicht aus Such flat textile structures are known, for example, from DE 20 2008 016 926 U1 and DE 10 2004 024 134 A1. DE 20 2008 016 926 U1 shows a cellulose cloth consisting of a fiber layer
flüssigkeitsabsorbierenden Zellstofffasern sowie einer einseitig daran gebundenen weiteren Schicht, wobei die weitere Schicht im Hinblick auf Farbe oder Farbmuster von der Faserschicht abweicht. Die Fasern der Faserschicht sind durch partielles Verpressen oder Verdichten der Zellstofffasern liquid-absorbing cellulose fibers and a further layer bonded to it on one side, the further layer deviating from the fiber layer in terms of color or color pattern. The fibers of the fiber layer are made by partially pressing or compacting the pulp fibers

DE 10 2004 024 134 A1 zeigt eine absorbierende Textilstruktur mit hoher Absorptionsleistung für Öle, Emulsionen, Chemikalien sowie andere Wasser- und Bodenschadstoffe. Die absorbierende Textilstruktur besteht aus einem Verbund mit einem umhüllten Saugkern, wobei zwischen einer dünnen, durchlässigen, dimensionsstabilen und flusenfreien Grund- und Deckschicht eine saug- und speicherfähige Schicht angeordnet ist, die aus in wirrer Lage angeordneten Endlosfilamenten gebildet ist. Dabei sind alle Schichten miteinander verbunden. Durch Variation der eingesetzten außenliegenden Vliesstoffschichten und dem mittig eingeschlossenen weitgehend unverfestigten Filamentvliesstoff kann in Abhängigkeit vom Anwendungsgebiet zur Aufnahme von DE 10 2004 024 134 A1 shows an absorbent textile structure with high absorption performance for oils, emulsions, chemicals and other water and soil pollutants. The absorbent textile structure consists of a composite with a wrapped absorbent core, with an absorbent and storable layer between a thin, permeable, dimensionally stable and lint-free base and cover layer, which is formed from continuous filaments arranged in a tangled position. All layers are connected to one another. By varying the external nonwoven layers used and the largely unconsolidated filament nonwoven enclosed in the center, depending on the area of application, it is possible to accommodate

Der Erfindung liegt die Aufgabe zugrunde, ein mehrlagiges textiles Gebilde bereitzustellen, welches bei hoher Wasseraufnahmefähigkeit gleichzeitig eine hohe Reinigungsleistung aufweist. The invention is based on the object of providing a multilayer textile structure which at the same time has a high cleaning performance with a high water absorption capacity.
Diese Aufgabe wird mit den Merkmalen von Anspruch 1 gelöst. Auf vorteilhafte Ausgestaltungen nehmen die Unteransprüche Bezug. This object is achieved with the features of claim 1. The subclaims refer to advantageous configurations.
Das erfindungsgemäße mehrlagige textile Flächengebilde umfasst zwei textile Oberschichten, wobei zwischen den beiden Oberschichten zumindest eine textile Mittelschicht angeordnet ist, wobei die Oberschichten Mikrofasern umfassen. The multilayer textile fabric according to the invention comprises two textile upper layers, with at least one textile middle layer being arranged between the two upper layers, the upper layers comprising microfibers.
Dadurch, dass die Oberschichten Mikrofasern umfassen, ist es möglich, die Oberschichten mit einer verhältnismäßig geringen Porosität auszurüsten. Durch die verhältnismäßig geringe Porosität verringert sich die Wasserabgabe über die Oberschichten. Dadurch, dass die Oberschichten Mikrofasern umfassen, weisen diese eine sehr gute Reinigungsleistung auf. Zum einen wird durch den Einsatz von Mikrofasern und die damit einhergehenden Kapillareffekte zwischen den Fasern ein guter Wasserhaushalt erzielt. Die in der Mittelschicht im Inneren des Tuches gespeicherte Reinigungsflüssigkeit wird sehr gleichmäßig und mit kleinsten Tropfen auf die zu reinigende Because the top layers comprise microfibers, it is possible to provide the top layers with a relatively low porosity. The relatively low porosity reduces the amount of water released through the top layers. Because the top layers comprise microfibers, they have a very good cleaning performance. On the one hand, a good water balance is achieved through the use of microfibres and the associated capillary effects between the fibers. The cleaning liquid stored in the middle layer on the inside of the cloth is very even and with the smallest drops on the surface to be cleaned
Oberfläche abgeben, dadurch können auch glatte sowie glänzende Surface, this can also be smooth and shiny
Oberflächen weitgehend streifenfrei gereinigt werden. Zum anderen weisen textile Oberflächen aus Mikrofasern eine sehr gute Reinigungsleistung gegenüber fetthaltigen Verschmutzungen auf, wenn als Reinigungsflüssigkeit nur Wasser ohne chemische Zusätze verwendet wird. Dabei bildet die Mittelschicht vorzugsweise ein Wasserreservoir, so dass Flüssigkeit im Inneren des mehrlagigen textilen Gebildes gespeichert werden kann. Surfaces can be cleaned largely streak-free. On the other hand, textile surfaces made of microfibres have a very good cleaning performance against greasy soiling if only water without chemical additives is used as the cleaning fluid. The middle layer preferably forms a water reservoir, so that liquid can be stored in the interior of the multilayer textile structure.
Die Oberschichten und die Mittelschichten können als Maschenware ausgebildet sein. Maschenwaren sind textile Flächengebilde, bei denen aus Garnen gebildete Schlaufen in andere Schlaufen hineingeschlungen sind. Dabei bildet sich ein Verbund aus Maschen. Maschenware weist eine hohe Dehnbarkeit und Elastizität bei gleichzeitig voluminösem Griff auf. The upper layers and the middle layers can be designed as knitted fabrics. Knitted fabrics are textile fabrics in which loops made from yarns are looped into other loops. This creates a network of meshes. Knitwear has a high degree of stretchability and elasticity with a voluminous handle at the same time.
Dabei können die Oberschichten und die Mittelschicht als Gewirke The upper layers and the middle layer can be knitted
ausgebildet sein. Gewirke sind aus Fadensystemen oder Fasernsystemen durch Maschenbildung auf einer Wirkmaschine hergestellte Flächengebilde. Im Unterschied zu Strickwaren bilden der Faden oder die Fasern bei einer Wirkware übereinanderstehende Maschen. Der Faden oder die Fasern verlaufen senkrecht und bilden mit dem benachbarten Faden oder den benachbarten Fasern ein Maschenstäbchen. Der Vorteil von gewirkter Flächenware ist die große Formstabilität. In Verbindung mit be trained. Knitted fabrics are flat structures made from thread systems or fiber systems by stitch formation on a knitting machine. In contrast to knitted goods, the thread or the fibers form superimposed stitches in a knitted fabric. The thread or fibers run vertically and form a wale with the adjacent thread or fibers. The advantage of knitted fabrics is their great dimensional stability. Combined with
Reinigungstüchern führt dies bei Verformung zu einem verbesserten Cleaning wipes this leads to an improved deformation
Rückstellvermögen, so dass sich das mehrlagige textile Gebilde besser auswringen lässt. Resilience so that the multilayered textile structure can be wrung out better.
Die Oberschichten und die Mittelschicht können durch Maschenbildung miteinander verbunden sein. Dadurch ergibt sich eine feste Verbindung der Oberschichten und der Mittelschicht miteinander, so dass die Oberschichten und die Mittelschicht verliersicher miteinander verbunden sind. Dabei können die Oberschichten und die Mittelschicht durch Wirkverbindung miteinander verbunden sein. Dies ermöglicht die Fierstellung des mehrlagigen textilen Flächengebildes auf einer Wirkmaschine in einem Zug. Die Oberschichten und die Mittelschicht sind dabei fest miteinander verbunden. The top layers and the middle layer can be connected to one another by knitting. This results in a firm connection of the upper layers and the middle layer to one another, so that the upper layers and the middle layer are securely connected to one another. The upper layers and the middle layer can be connected to one another by operative connection. This enables the multi-layer textile fabric to be folded on a knitting machine in one go. The upper and middle classes are firmly connected to one another.
Das Garn für die zumindest eine Mittelschicht kann Monofilamente enthalten. Ein derartiges Garn weist vorzugsweise einen Titer von mindestens 5 dtex, vorzugsweise mindestens 10 dtex, weiter vorzugsweise von mindestens 25 dtex auf. Bei der Verarbeitung eines derartigen Garnes für die Mittelschicht entsteht eine verhältnismäßig dicke Mittelschicht mit einer hohen Porosität, welche insbesondere dazu geeignet ist, hohe Wassermengen aufzunehmen und dem mehrlagigen textilen Gebilde eine Mindestdicke zu verleihen. The yarn for the at least one middle layer can contain monofilaments. Such a yarn preferably has a titer of at least 5 dtex, preferably at least 10 dtex, more preferably at least 25 dtex. When processing such a yarn for the middle layer, a relatively thick middle layer with a high porosity is created, which is particularly suitable for absorbing large amounts of water and for giving the multilayered textile structure a minimum thickness.
Aufgrund der recht hohen Porosität weist die Mittelschicht auch ein Due to the rather high porosity, the middle layer also shows a bit
verhältnismäßig geringes Flächengewicht auf, so dass das mehrlagige textile Gebilde insgesamt ein verhältnismäßig geringes Flächengewicht aufweist. relatively low weight per unit area, so that the multilayer textile structure has a relatively low area weight overall.
Vorzugsweise bilden beide Oberschichten Reinigungsflächen. Both top layers preferably form cleaning surfaces.
Dementsprechend bildet das mehrlagige textile Gebilde ein Reinigungstuch. Aufgrund der Ausrüstung der Oberschichten mit Mikrofasern ergibt sich eine besonders gute Reinigungsleistung gegenüber fetthaltigen Verschmutzungen. Insofern eignet sich ein derartiges Reinigungstuch besonders zur Reinigung in Flaushalten. Accordingly, the multi-layer textile structure forms a cleaning cloth. Finishing the top layers with microfibres results in a particularly good cleaning performance against greasy soiling. In this respect, a cleaning cloth of this type is particularly suitable for cleaning in unfamiliar households.
Das Garn für die Oberschichten ist vorzugsweise als Multifilamentgarn ausgebildet. Multifilamentgarne weisen im Vergleich zu Monofilamentgarne einen geringeren Durchmesser und ein geringeres Flächengewicht auf. The yarn for the upper layers is preferably designed as a multifilament yarn. In comparison to monofilament yarns, multifilament yarns have a smaller diameter and a lower weight per unit area.
Dabei kann das Garn für die Oberschichten als Stapelfasergarn ausgebildet sein. Stapelfasergarne enthalten Fasern mit endlicher Länge. Dadurch können verschiedene Faserarten gemischt werden und insbesondere Naturfasern verarbeitet werden. The yarn for the upper layers can be designed as a staple fiber yarn. Staple fiber yarns contain fibers of finite length. This means that different types of fiber can be mixed and natural fibers in particular can be processed.
Der Gewichtsanteil der Mikrofasern bezogen auf das Gewicht der jeweiligen Oberschicht beträgt vorzugweise mindestens 30 Gew.%. Bei einem derartigen Anteil von Mikrofasern ergeben sich eine besonders hohe Reinigungsleistung und eine besonders geringe Porosität, so dass sich ein besonders hohes Wasserspeichervermögen des mehrlagigen textilen Gebildes ergibt. The proportion by weight of the microfibers based on the weight of the respective top layer is preferably at least 30% by weight. With such a proportion of microfibers, a particularly high cleaning performance and a particularly low porosity result, so that the multilayer textile structure has a particularly high water storage capacity.
Der Titer der Mikrofasern der Oberschichten kann weniger als 1 dtex betragen. Fasern mit einem Titer von weniger als 1 dtex werden als Mikrofasern bezeichnet und weisen insbesondere gegenüber fetthaltigen Verschmutzungen ein hohes Reinigungsvermögen auf. The titer of the microfibers of the top layers can be less than 1 dtex. Fibers with a titer of less than 1 dtex are considered Microfibers denote and have a high cleaning power, especially with regard to greasy soiling.
Die Mittelschicht kann Mikrofasern enthalten. Dies ist insbesondere dann vorteilhaft, wenn eine höhere Wasseraufnahmekapazität erzielt werden soll. The middle layer can contain microfibers. This is particularly advantageous when a higher water absorption capacity is to be achieved.
Der Gewichtsanteil der Mikrofasern bezogen auf das Gewicht der Mittelschicht kann dabei mindestens 10 Gew.% betragen. The proportion by weight of the microfibers based on the weight of the middle layer can be at least 10% by weight.
Die Oberschichten können eine dreidimensionale Reliefstruktur aufweisen. Daraus kann ein besonders guter Griff resultieren, was insbesondere bei der Verwendung als Reinigungstuch vorteilhaft ist.
