Definitions
- the invention relates to a floor covering designed as pile fabric for sports surfaces, in particular artificial turf, with an opening-bearing and therefore water-permeable carrier web, a fibrous material web needled onto the latter and with pole elements attached to the carrier web and forming the pole with their free end regions.
- a similar floor covering which has the features of the preamble of claim 1, is known from DE-A-29 35 387.
- the invention relates to such a floor covering of the type mentioned above, in which the pole elements are knitted into the carrier webs.
- Known floor coverings in the form of a pile fabric, in particular in the form of artificial turf are produced as tufted fabrics with a textile carrier web, as a knitted fabric, knitted fabric or the like and then optionally provide the carrier web with a partial or full-area back coating, in the latter case, however, being ensured by openings in the back coating must that the artificial turf is permeable to water; the latter is important because in the case of such a floor covering laid outdoors, rain and melt water must be able to flow down through the floor covering, but also the water applied from above when the floor covering is moistened - in this connection it must be pointed out that optimal example properties of such a floor covering only arise when the surface of the covering is somewhat damp.
- the floor covering for sports surfaces known from DE-A-38 35 880 which is designed as a pile fabric, is also unsatisfactory; it has a water-permeable carrier web, to which upwardly projecting pole elements are attached with their free end regions, as well as under the carrier web and at a distance therefrom a nonwoven web, which is also water-permeable, and in the space between the carrier web and nonwoven web. Web are connected to the latter, approximately hemispherical cushion elements made of closed-cell plastic foam, which should ensure a satisfactory tread elasticity of this known flooring.
- the space between the carrier web and the nonwoven web left free by these cushioning elements is filled with a granulate filling, which is in particular a mixture of sand and rubber granulate.
- the nonwoven web and the granulate filling are intended to ensure a certain water retention capacity of this known floor covering, to which the upholstery elements cannot contribute because, as mentioned, they consist of a closed-cell plastic foam.
- Sand, rubber granulate or a mixture of these two materials can hardly store water, and water retained by the nonwoven web will hardly reach its surface again with this edged flooring, since there is a gap between the nonwoven web and the recorded surface of the flooring non-water-permeable upholstery elements, the lower, flat surfaces of which cover most of the nonwoven web.
- this object can be achieved in that the fiber material web is arranged on the underside of the carrier web and, when the fiber material web is needled, tufts of fiber protrude upward from the fiber material web through the carrier web between the free end regions of the pole elements.
- the fibrous material web has a double function: on the one hand, it acts as a water reservoir for water accumulating on the surface of the covering and which has passed down through the water-permeable carrier web, and on the other hand, based on a capillary action, water becomes through the fiber tufts protruding through the carrier web transported by the fibrous material web, which acts as a water reservoir, through the carrier web back into the area of the covering surface as soon as it threatens to dry, especially when the floor covering is being used and pressure is exerted on it from above, resulting in a compression of the fibrous material web in the recorded area.
- the water storage and retention capacity of the fibrous material web can be selected by an appropriate choice, for. B.
- the fibrous material web it could, for. B. is a felt or a knitted fabric, but even better results can be achieved with a nonwoven fabric that can store a multiple of its own weight in water.
- the needling of a nonwoven fabric on the carrier web of an artificial turf is known per se (DE-A-29 35 387); in this known artificial turf, however, the nonwoven fabric is needled onto the upper side of the carrier web of the artificial turf designed as tufted goods, and the tufts of fibers pushed through the carrier web during the needling of the nonwoven fabric protrude downward from the carrier web between the anchoring feet of the pole elements of this known artificial turf.
- the nonwoven should serve the purpose of covering the carrier web so that its color is not visible from above, and secondly the fibers pressed through the carrier web from top to bottom have a coating compound applied to the underside of the carrier web a repellent effect on the coating composition, so that the openings in the carrier web required for the water permeability of the artificial turf are at least not completely closed by the back coating composition.
- the task and arrangement of the nonwoven fabric in this known artificial turf are completely different than in the floor covering according to the invention.
- the fibrous material web could be needled onto the carrier web from below before the pole elements, e.g. B. by tufts, are introduced into the carrier web.
- the pole elements have anchoring feet arranged on the underside of the carrier web, which are covered by the fiber material web.
- pole elements introduced into the carrier web by tufts are then better fixed in the carrier web, and in addition, the anchoring feet of the pole elements are not subject to the risk of being chafed due to the use of the flooring when laying the flooring on a rough surface.
- a floor covering according to the invention can be produced without an adhesive or a back coating material, so that the floor covering according to the invention can be produced as a fully recyclable material.
- a fiber material web impregnated to stiffen its fibers is recommended.
- a fiber material web impregnated with a latex emulsion is particularly advantageous, for the following reason: a sports surface floor covering must be replaced after about 5 to 10 years; within such a period of time, however, latex decomposes due to aging and is washed away when the floor covering is sprinkled, so that only pure plastic material has to be worked up when the floor covering is recycled.
- an additional shape-stabilizing material web can also be needled onto the carrier web or the knitted back at the same time as the fiber material web, e.g. B. a mesh, a nonwoven fabric or the like.
- the drawing shows a carrier web 10 designed as a tufting base fabric, which was produced in the present case from plastic tapes 10a and whose water permeability can be ensured in a variety of ways, e.g. B. by the width and density of the plastic ribbon 10a, d. H. by the transverse spacing of the plastic tapes forming the warp and weft threads from one another. Pole elements 12, the anchoring feet 12 a of which lie on the back of the carrier web 10, were introduced into the carrier web 10 using the tufting process. A nonwoven fabric layer 14 was then needled onto the carrier web 10 from below, as a result of which holes 10b were created in the carrier web 10 and pushed through these fiber tufts 14a.

Description
Die Erfindung betrifft einen als Polware ausgebildeten Bodenbelag für Sportflächen, insbesondere Kunstrasen, mit einer Öffnungen aufweisenden und deshalb wasserdurchlässigen Trägerbahn, einer an diese angenadelten Fasermaterialbahn sowie mit an der Trägerbahn befestigten, mit ihren freien Endbereichen den Pol bildenden Polelementen. Ein dergleicher Bodenbelag, der die Merkmale des Oberbegriffes des Anspruchs 1 aufweist, ist aus der DE-A-29 35 387 bekannt. Insbesondere betrifft die Erfindung einen solchen Bodenbelag der vorstehend erwähnten Art, bei dem die Polelemente in die Trägerbahnen eingestrickt sind.The invention relates to a floor covering designed as pile fabric for sports surfaces, in particular artificial turf, with an opening-bearing and therefore water-permeable carrier web, a fibrous material web needled onto the latter and with pole elements attached to the carrier web and forming the pole with their free end regions. A similar floor covering, which has the features of the preamble of claim 1, is known from DE-A-29 35 387. In particular, the invention relates to such a floor covering of the type mentioned above, in which the pole elements are knitted into the carrier webs.
Insbesondere als Kunstrasen ausgebildete bekannte Bodenbeläge in Form einer Polware werden als Tuftingware mit einer textilen Trägerbahn, als Gestrick, Gewirke oder dergleichen hergestellt und dann die Trägerbahn gegebenenfalls mit einer partiellen oder vollflächigen Rückenbeschichtung versehen, wobei in letzterem Fall jedoch durch Öffnungen in der Rückenbeschichtung sichergestellt werden muß, daß der Kunstrasen wasserdurchlässig ist; letzteres ist deshalb wichtig, weil bei einem im Freien verlegten derartigen Bodenbelag Regen- und Schmelzwasser durch den Bodenbelag hindurch nach unten abfließen können muß, ebenso aber auch das beim Befeuchten des Bodenbelags auf diesen von oben aufgebrachte Wasser - in diesem Zusammenhang muß darauf hingewiesen werden, daß sich optimale Bespieleigenschaften eines solchen Bodenbelags nur dann einstellen, wenn die Belagsoberfläche etwas feucht ist.Known floor coverings in the form of a pile fabric, in particular in the form of artificial turf, are produced as tufted fabrics with a textile carrier web, as a knitted fabric, knitted fabric or the like and then optionally provide the carrier web with a partial or full-area back coating, in the latter case, however, being ensured by openings in the back coating must that the artificial turf is permeable to water; the latter is important because in the case of such a floor covering laid outdoors, rain and melt water must be able to flow down through the floor covering, but also the water applied from above when the floor covering is moistened - in this connection it must be pointed out that optimal example properties of such a floor covering only arise when the surface of the covering is somewhat damp.
Bekannte, wasserdurchlässige Bodenbeläge in Form eines Kunstrasens trocknen nun nach einem Befeuchten relativ schnell ab, insbesondere unter dem Einfluß von Sonne und Wind bei sich im Freien befindlichen Sportflächen.Known, water-permeable floor coverings in the form of an artificial turf now dry relatively quickly after moistening, in particular under the influence of the sun and wind Outdoor sports areas.
In dieser Hinsicht ist auch der aus der DE-A-38 35 880 bekannte, als Polware ausgebildete Bodenbelag für Sportflächen nicht befriedigend; er besitzt eine wasserdurchlässige Trägerbahn, an der nach oben ragende, mit ihren freien Endbereichen den Pol bildende Polelemente befestigt sind, sowie unter der Trägerbahn und im Abstand von dieser eine Vliesstoff-Bahn, welche gleichfalls wasserdurchlässig ist, und im Zwischenraum zwischen Trägerbahn und Vliesstoff-Bahn befinden sich mit der letzteren verbundene, ungefähr halbkugelförmige Polsterelemente aus geschlossenzelligem Kunststoffschaum, welche für eine befriedigende Trittelastizität dieses bekannten Bodenbelags sorgen sollen. Der von diesen Polsterelementen freigelassene Zwischenraum zwischen Trägerbahn und Vliesstoff-Bahn ist mit einer Granulatfüllung ausgefüllt, bei der es sich insbesondere um ein Gemisch aus Sand und Gummigranulat handelt. Die Vliesstoff-Bahn und die Granulatfüllung sollen für ein gewisses Wasser-Rückhaltevermögen dieses bekannten Bodenbelags sorgen, wozu die Polsterelemente nicht beitragen können, weil sie, wie erwähnt, aus einem geschlossenzelligen Kunststoffschaum bestehen. Sand, Gummigranulat oder ein Gemisch aus diesen beiden Materialien kann aber kaum Wasser speichern, und von der Vliesstoff-Bahn zurückgehaltenes Wasser wird bei diesem bekanten Bodenbelag kaum wieder an dessen Oberfläche gelangen, da sich zwischen der Vliesstoff-Bahn und der bespielten Oberfläche des Bodenbelags die nicht-wasserdurchlässigen Polsterelemente befinden, deren untere, ebene Flächen den größten Teil der Vliesstoff-Bahn abdecken.In this regard, the floor covering for sports surfaces known from DE-A-38 35 880, which is designed as a pile fabric, is also unsatisfactory; it has a water-permeable carrier web, to which upwardly projecting pole elements are attached with their free end regions, as well as under the carrier web and at a distance therefrom a nonwoven web, which is also water-permeable, and in the space between the carrier web and nonwoven web. Web are connected to the latter, approximately hemispherical cushion elements made of closed-cell plastic foam, which should ensure a satisfactory tread elasticity of this known flooring. The space between the carrier web and the nonwoven web left free by these cushioning elements is filled with a granulate filling, which is in particular a mixture of sand and rubber granulate. The nonwoven web and the granulate filling are intended to ensure a certain water retention capacity of this known floor covering, to which the upholstery elements cannot contribute because, as mentioned, they consist of a closed-cell plastic foam. Sand, rubber granulate or a mixture of these two materials can hardly store water, and water retained by the nonwoven web will hardly reach its surface again with this edged flooring, since there is a gap between the nonwoven web and the recorded surface of the flooring non-water-permeable upholstery elements, the lower, flat surfaces of which cover most of the nonwoven web.
Aufgabe der vorliegenden Erfindung war es deshalb, einen wasserdurchlässigen, als Polware ausgebildeten Bodenbelag für Sportflächen zu schaffen, welcher nach einer Befeuchtung länger die erwünschten spieltechnischen Eigenschaften aufweist als die bekannten Kunstrasen.It was therefore an object of the present invention to provide a water-permeable floor covering for sports surfaces which is designed as a pile fabric and which, after moistening, has the desired playing characteristics longer than the known artificial turf.
Erfindungsgemäß läßt sich diese Aufgabe dadurch lösen, daß die Fasermaterialbahn an der Unterseite der Trägerbahn angeordnet ist und beim Annadeln der Fasermaterialbahn erzeugte Faserbüschel von der Fasermaterialbahn nach oben durch die Trägerbahn hindurch zwischen die freien Endbereiche der Polelemente ragen.According to the invention, this object can be achieved in that the fiber material web is arranged on the underside of the carrier web and, when the fiber material web is needled, tufts of fiber protrude upward from the fiber material web through the carrier web between the free end regions of the pole elements.
Bei dem erfindungsgemäßen Bodenbelag übernimmt die Fasermaterialbahn eine doppelte Funktion: Zum einen wirkt sie als Wasserspeicher für auf der Belagsoberfläche anfallendes und durch die wasserdurchlässige Trägerbahn nach unten hindurchgetretenes Wasser, und zum anderen wird, beruhend auf einer Kapillarwirkung, durch die durch die Trägerbahn hindurchragenden Faserbüschel Wasser von der als Wasserspeicher wirkenden Fasermaterialbahn durch die Tragerbahn hindurch zurück in den Bereich der Belagsoberfläche transportiert, sobald diese abzutrocknen droht, und zwar insbesondere dann, wenn der Bodenbelag bespielt und dadurch von oben Druck auf ihn ausgeübt wird, was zu einem Zusammenpressen der Fasermaterialbahn in dem bespielten Bereich führt. Das Wasserspeicher- und Rückhaltevermögen der Fasermaterialbahn läßt sich durch eine entsprechende Wahl z. B. der folgenden Parameter bestimmen und auswählen: Dicke, Dichte und Struktur der Fasermaterialbahn sowie Art der Fasern, aus welchen sie hergestellt wird. Bei der Fasermaterialbahn könnte es sich z. B. um einen Filz oder ein Fasergewirke handeln, noch bessere Ergebnisse lassen sich aber mit einem Faservlies erreichen, welches ein Vielfaches seines Eigengewichts an Wasser speichern kann.With the floor covering according to the invention, the fibrous material web has a double function: on the one hand, it acts as a water reservoir for water accumulating on the surface of the covering and which has passed down through the water-permeable carrier web, and on the other hand, based on a capillary action, water becomes through the fiber tufts protruding through the carrier web transported by the fibrous material web, which acts as a water reservoir, through the carrier web back into the area of the covering surface as soon as it threatens to dry, especially when the floor covering is being used and pressure is exerted on it from above, resulting in a compression of the fibrous material web in the recorded area. The water storage and retention capacity of the fibrous material web can be selected by an appropriate choice, for. B. determine and select the following parameters: thickness, density and structure of the fiber material web and type of fibers from which it is produced. In the fibrous material web it could, for. B. is a felt or a knitted fabric, but even better results can be achieved with a nonwoven fabric that can store a multiple of its own weight in water.
Das Annadeln eines Faservlieses an die Trägerbahn eines Kunstrasens ist an sich bekannt (DE-A-29 35 387); bei diesem bekannten Kunstrasen ist das Faservlies jedoch auf die Oberseite der Trägerbahn des als Tuftingware ausgebildeten Kunstrasens aufgenadelt, und die beim Aufnadeln des Faservlieses durch die Trägerbahn hindurchgestoßenen Faserbüschel ragen zwischen den Verankerungsfüßen der Polelemente dieses bekannten Kunstrasens nach unten aus dessen Trägerbahn heraus. Bei diesem bekannten Kunstrasen soll das Faservlies zum einen dem Zweck dienen, die Trägerbahn abzudecken, so daß deren Farbe von oben nicht sichtbar ist, und zum anderen haben die von oben nach unten durch die Trägerbahn hindurchgedrückten Fasern beim Aufbringen einer Beschichtungsmasse auf die Unterseite der Trägerbahn eine abweisende Wirkung auf die Beschichtungsmasse, so daß die für die Wasserdurchlässigkeit des Kunstrasens erforderlichen Öffnungen in der Trägerbahn durch die Rückenbeschichtungsmasse zumindest nicht vollständige verschlossen werden. Aufgabe und Anordnung des Faservlieses bei diesem bekannten Kunstrasen sind also völlig andere als bei dem erfindungsgemäßen Bodenbelag.The needling of a nonwoven fabric on the carrier web of an artificial turf is known per se (DE-A-29 35 387); in this known artificial turf, however, the nonwoven fabric is needled onto the upper side of the carrier web of the artificial turf designed as tufted goods, and the tufts of fibers pushed through the carrier web during the needling of the nonwoven fabric protrude downward from the carrier web between the anchoring feet of the pole elements of this known artificial turf. In this known artificial turf, the nonwoven should serve the purpose of covering the carrier web so that its color is not visible from above, and secondly the fibers pressed through the carrier web from top to bottom have a coating compound applied to the underside of the carrier web a repellent effect on the coating composition, so that the openings in the carrier web required for the water permeability of the artificial turf are at least not completely closed by the back coating composition. The task and arrangement of the nonwoven fabric in this known artificial turf are completely different than in the floor covering according to the invention.
An sich könnte bei der Herstellung eines erfindungsgemäßen Bodenbelags die Fasermaterialbahn von unten auf die Trägerbahn aufgenadelt werden, ehe die Polelemente, z. B. durch Tuften, in die Trägerbahn eingebracht werden. Vorteilhafter ist es jedoch, wenn bei der Herstellung eines erfindungsgemäßen Bodenbelags auf den fertigen Kunstrasen von unten eine Fasermaterialbahn aufgenadelt wird, denn dann weisen die Polelemente auf der Trägerbahnunterseite angeordnete Verankerungsfüße auf, welche von der Fasermaterialbahn abgedeckt werden. Vor allem durch Tuften in die Trägerbahn eingebrachte Polelemente sind dann in der Trägerbahn besser fixiert, und außerdem unterliegen die Verankerungsfüße der Polelemente beim Verlegen des Bodenbelags auf einem rauhen Untergrund nicht der Gefahr, infolge des Bespielens des Bodenbelags durchgescheuert zu werden. Bei jeder Art von Polware dienen außerdem die durch die Trägerbahn hindurchgestoßenen und in den Bereich zwischen den Polfäden oder -bändchen hineinragenden Faserbüschel einer Stabilisierung des eigentlichen Pols des Bodenbelags. Schließlich wird durch das Aufnadeln der Fasermaterialbahn die Wasserdurchlässigkeit der Trägerbahn vergrößert.As such, in the manufacture of a floor covering according to the invention, the fibrous material web could be needled onto the carrier web from below before the pole elements, e.g. B. by tufts, are introduced into the carrier web. However, it is more advantageous if a fiber material web is needled from below onto the finished artificial turf when producing a floor covering according to the invention, because then the pole elements have anchoring feet arranged on the underside of the carrier web, which are covered by the fiber material web. In particular, pole elements introduced into the carrier web by tufts are then better fixed in the carrier web, and in addition, the anchoring feet of the pole elements are not subject to the risk of being chafed due to the use of the flooring when laying the flooring on a rough surface. With any type of pile fabric, the fiber tufts pushed through the carrier web and protruding into the area between the pile threads or ribbons also serve to stabilize the actual pile of the floor covering. Finally, the need for the fibrous material web to increase the water permeability of the carrier web.
Aufgrund der vorstehend geschilderten Effekte kann ein erfindungsgemäßer Bodenbelag ohne Klebstoff oder eine Rückenbeschichtungsmasse hergestellt werden, so daß sich der erfindungsgemäße Bodenbelag als voll recyclebares Material herstellen läßt. Um ein Recycling des Bodenbelags noch weiter zu vereinfachen, empfiehlt es sich, Trägerbahn, Polelemente und Fasermaterialbahn sämtlich aus demselben Kunststoff herzustellen, und als besonders günstige Rohstoffe haben sich Polypropylen, Polyäthylen, Polyamid und Polyester erwiesen.Due to the effects described above, a floor covering according to the invention can be produced without an adhesive or a back coating material, so that the floor covering according to the invention can be produced as a fully recyclable material. To further simplify recycling of the floor covering, it is advisable to produce the carrier sheet, pile elements and fiber material sheet all from the same plastic, and polypropylene, polyethylene, polyamide and polyester have proven to be particularly cheap raw materials.
Schließlich empfiehlt sich die Verwendung einer zur Versteifung ihrer Fasern imprägnierten Fasermaterialbahn. Besonders vorteilhaft ist eine mit einer Latexemulsion imprägnierte Fasermaterialbahn, und zwar aus folgendem Grund: Ein Sport-flächen-Bodenbelag muß nach ca. 5 - 10 Jahren erneuert werden; innerhalb eines solchen Zeitraums zersetzt sich Latex jedoch durch Alterung und wird beim Berregnen des Bodenbelags weggespült, so daß beim Recyceln des Bodenbelags nur noch reines Kunststoffmaterial aufgearbeitet werden muß.Finally, the use of a fiber material web impregnated to stiffen its fibers is recommended. A fiber material web impregnated with a latex emulsion is particularly advantageous, for the following reason: a sports surface floor covering must be replaced after about 5 to 10 years; within such a period of time, however, latex decomposes due to aging and is washed away when the floor covering is sprinkled, so that only pure plastic material has to be worked up when the floor covering is recycled.
Schließlich sei noch darauf hingewiesen, daß durch das Annadeln der Fasermaterialbahn eine Flächenstabilisierung des Bodenbelags erreicht und somit die geforderte Maßhaltigkeit des Bodenbelags sichergestellt werden kann. Im Bedarfsfall kann aber gleichzeitig mit der Fasermaterialbahn auch noch eine zusätzlich formstabilisierende Materialbahn an die Trägerbahn bzw. den Gewirkerücken angenadelt werden, z. B. ein Gittergewebe, ein Vliesstoff oder dergleichen.Finally, it should be pointed out that the needling of the fibrous material web stabilizes the surface of the Flooring reached and thus the required dimensional accuracy of the flooring can be ensured. If necessary, an additional shape-stabilizing material web can also be needled onto the carrier web or the knitted back at the same time as the fiber material web, e.g. B. a mesh, a nonwoven fabric or the like.
Weitere Merkmale, Vorteile und Einzelheiten der Erfindung ergeben sich aus der beigefügten schematischen zeichnerischen Darstellung sowie der nachfolgenden Beschreibung einer besonders bevorzugten Ausführungsform des erfindungsgemäßen Bodenbelags; die Zeichnung zeigt einen Schnitt durch den als Tuftingware ausgebildeten Bodenbelag.Further features, advantages and details of the invention result from the attached schematic drawing and the following description of a particularly preferred embodiment of the floor covering according to the invention; the drawing shows a section through the floor covering designed as tufted goods.
Die Zeichnung zeigt eine als Tuftinggrundgewebe ausgebildete Trägerbahn 10, welche im vorliegenden Fall aus Kunststoffbändchen 10a hergestellt wurde und deren Wasserdurchlässigkeit auf die unterschiedlichste Weise sichergestellt werden kann, z. B. durch die Breite und Dichte der Kunststoffbändchen 10a, d. h. durch den Querabstand der die Kett- und Schußfäden bildenden Kunststoffbändchen voneinander. In die Trägerbahn 10 wurden im Tuftingverfahren Polelemente 12 eingebracht, deren Verankerungsfüße 12a auf der Rückseite der Trägerbahn 10 liegen. Dann wurde von unten auf die Trägerbahn 10 eine Faservliesschicht 14 aufgenadelt, wodurch in der Trägerbahn 10 Löcher l0b erzeugt und durch diese Faserbüschel 14a hindurchgestoßen wurden. Durch das Aufnadeln der Faservliesschicht 14 wurde also nicht nur diese an der Trägerbahn 10 befestigt, sondern es wurde auch die Wasserdurchlässigkeit der Trägerbahn erhöht und gleichzeitig gewährleistet, daß durch eine von den Faserbüscheln 14a bewirkte Kapillarwirkung in der Faservliesschicht 14 gespeichertes Wasser nach oben in den Bereich zwischen den von den freien Endbereichen der Polelemente 12 gebildeten Polfäden gefördert werden kann.The drawing shows a
