Abstract

Described is a pile-fabric floor-covering for sports surfaces, in particular synthetic-grass surfaces. The floor-covering has a substrate sheet which has apertures in it and is therefore permeable to water. Attached to the substrate by needling is a sheet of fibrous material. Also attached to the substrate are pile elements which form the pile. To extend the length of time the floor-covering can be played on after being dampened, the sheet of fibrous material is attached to the underside of the substrate, and tufts of fibres produced when the sheet of fibrous material is needled project up from the sheet of fibrous material through the substrate.

Description

Bodenbelag für Sportflächen Flooring for sports areas
Die Erfindung betrifft einen als Polware ausgebildeten Boden¬ belag für Sportflächen, insbesondere einen sogenannten Kunst¬ rasen, mit einer Öffnungen aufweisenden und deshalb wasser¬ durchlässigen Trägerbahn, einer an diese angenadelten Faser¬ materialbahn sowie mit an der Trägerbahn befestigten, den Pol bildenden Polelementen. 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 a so-called artificial turf, with a carrier web which has openings and is therefore permeable to water, a fibrous material web needled to this, and with pole elements attached to the carrier web and forming the pole. 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 texti- len Trägerbahn, als Gestrick, Gewirke oder dergleichen herge¬ stellt und dann die Trägerbahn gegebenenfalls mit einer par¬ tiellen oder vollflächigen Rückenbeschichtung versehen, wobei in letzterem Fall jedoch durch Öffnungen in der Rückenbe¬ schichtung sichergestellt werden muß, daß der Kunstrasen was¬ serdurchlässig ist; letzteres ist deshalb wichtig, weil bei einem im Freien verlegten derartigen Bodenbelag Regen- und Schmelzwasser durch den Bodenbelag hindurch nach unten ab¬ fließen können muß, ebenso aber auch das beim Befeuchten des Bodenbelags auf diesen von oben aufgebrachte Wasser - in die¬ sem Zusammenhang muß darauf hingewiesen werden, daß sich op¬ timale Bespieleigenschaften eines solchen Bodenbelags nur dann einstellen, wenn die Belagsoberfläche etwas feucht ist.Known floor coverings in the form of a pile of goods, in particular in the form of artificial turf, are produced as tufted goods 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, by Openings in the back coating must be ensured that the artificial turf is water-permeable; 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 context it should be pointed out that optimum example properties of such a floor covering only occur when the surface of the covering is somewhat moist.
Bekannte, wasserdurchlässige Bodenbeläge in Form eines Kunst¬ rasens trocknen nun nach einem Befeuchten relativ schnell ab, insbesondere unter dem Einfluß von Sonne und Wind bei sich im Freien befindlichen Sportflächen, weshalb der Erfindung die Aufgabe zugrunde lag, einen wasserdurchlässigen, als Polware ausgebildeten Bodenbelag für Sportflächen zu schaffen, wel¬ cher nach einer Befeuchtung länger die erwünschten spieltech¬ nischen Eigenschaften aufweist als die bekannten Kunstrasen.Known, water-permeable floor coverings in the form of an artificial lawn now dry relatively quickly after moistening, in particular under the influence of the sun and wind Outdoor sports areas, which is why the invention was based on the task of creating a water-permeable floor covering for sports areas designed as a pile fabric, which after moistening has the desired technical playing properties longer than the known artificial turf.
Erfindungsgemäß läßt sich diese Aufgabe dadurch lösen, daß an der Unterseite der Trägerbahn eine angenadelte Fasermaterial¬ bahn angeordnet wird und beim Annadeln der Fasermaterialbahn erzeugte Faserbüschel von der Fasermaterialbahn nach oben durch die Trägerbahn hindurchragen. Besonders vorteilhaft ist es, wenn die beim Annadeln nach oben durch die Trägerbahn hindurchgestoßenen Faserbüschel in die Bereiche zwischen den eigentlichen Pol hineinragen. 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 an¬ deren wird, beruhend auf einer Kapillarwirkung, durch die durch die Trägerbahn hindurchragenden Faserbüschel Wasser von der als Wasserspeicher wirkenden Fasermaterialbahn durch die Trägerbahn hindurch zurück in den Bereich der Belagsoberflä¬ che 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 Zusammen- ' pressen der Fasermaterialbahn in dem bespielten Bereich führt. Das Wasserspeicher- und Rückhaltevermögen der Faser- materialbahn läßt sich durch eine entsprechende Wahl z. B. der folgenden Parameter bestimmen und auswählen: Dicke, Dich¬ te 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. 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 Ober¬ seite der Trägerbahn des als Tuftingware ausgebildeten Kunst¬ rasens aufgenadelt, und die beim Aufnadeln des Faservlieses durch die Trägerbahn hindurchgestoßenen Faserbüschel ragen zwischen den Verankerungsfußen der Polelemente dieses bekann¬ ten 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 Fa¬ sern beim Aufbringen einer Beschichtungsmasse auf die Unter¬ seite der Trägerbahn eine abweisende Wirkung auf die Be¬ schichtungsmasse, so daß die für die Wasserdurchlässigkeit des Kunstrasens erforderlichen Öffnungen in der Trägerbahn durch die Rückenbeschichtungsmasse zumindest nicht vollstän¬ dige verschlossen werden. Aufgabe und Anordnung des Faser¬ vlieses bei diesem bekannten Kunstrasen sind also völlig andere als bei dem erfindungsgemäßen Bodenbelag.According to the invention, this object can be achieved in that a needled fiber material web is arranged on the underside of the carrier web and fiber tufts produced when the fiber material web is needled protrude upward through the carrier web from the fiber material web. It is particularly advantageous if the tufts of fibers pushed upward through the carrier web during the needling project into the areas between the actual pile. In 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 is based on a capillary action, through which protrudes through the carrier web Tuft of fibers transports water from 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 out, in particular when the floor covering is used and pressure is exerted on it from above, resulting in a combination - 'pressing the fiber material web leads in the recorded area. The water storage and retention capacity of the fibrous material web can be selected, for example, by an appropriate choice. 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 fiber, but even better results can be achieved with a nonwoven fabric, which 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 when the nonwoven fabric is needled protrude downward between the anchoring feet of the pole elements of this known artificial turf Carrier web out. In this known artificial turf, the fiber fleece is intended on the one hand to cover the carrier web so that its color is not visible from above, and on the other hand the fibers pressed through the carrier web from top to bottom have a coating composition applied to the bottom ¬ side of the carrier web has a repellent effect on the coating material, 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 material. The task and arrangement of the fiber fleece in this known artificial turf are therefore 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 Träger¬ bahn aufgenadelt werden, ehe die Polelemente, z. B. durch Tuften, in die Trägerbahn eingebracht werden. Vorteilhafter ist es jedoch, wenn bei der Herstellung eines erfindungsge¬ mäßen Bodenbelags auf den fertigen Kunstrasen von unten eine Fasermaterialbahn aufgenadelt wird, denn dann weisen die Pol- elemente auf der Trägerbahnunterseite angeordnete Veranke¬ rungsfüße 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 hineinragen¬ den Faserbüschel einer Stabilisierung des eigentlichen Pols des Bodenbelags. Schließlich wird durch das Aufnadeln der Fasermaterialbahn die Wasserdurchlässigkeit der Trägerbahn vergrößert.As such, when producing 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 on 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 when laying the floor covering on a rough surface are not subject to the risk of being worn through as a result of the floor covering being used. With each type of pile fabric, the fiber tufts which have passed through the carrier web and protrude 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 erfin¬ dungsgemäßer Bodenbelag ohne Klebstoff oder eine Rückenbe- schichtungsmasse hergestellt werden, so daß sich der erfin- dungsgemäße Bodenbelag als voll recyclebares Material her¬ stellen läßt. Um ein Recycling des Bodenbelags noch weiter zu vereinfachen, empfiehlt es sich, Trägerbahn, Polelemente und Fasermaterialbahn sämtlich aus demselben Kunststoff herzu¬ stellen, und als besonders günstige Rohstoffe haben sich Polypropylen, Polyäthylen, Polyamid und Polyester erwiesen.On the basis of the effects described above, a floor covering according to the invention can be produced without adhesive or a back coating material, so that the floor covering according to the invention can be produced as a fully recyclable material. In order to further simplify recycling of the floor covering, it is advisable to produce the carrier web, pole elements and fiber material web 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 Verstei¬ fung 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 wer¬ den; 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 reinforce 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 renewed 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 Anna¬ deln 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 Trä¬ gerbahn bzw. den Gewirkerücken angenadelt werden, z. B. ein Gittergewebe, ein Vliesstoff oder dergleichen.Finally, it should be pointed out that the needling of the fiber material web stabilizes the surface of the Flooring reached and thus the required dimensional accuracy of the flooring can be ensured. If necessary, however, 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. B. a mesh, a nonwoven fabric or the like.
Weitere Merkmale,- Vorteile und Einzelheiten der Erfindung er¬ geben sich aus der beigefügten schematischen zeichnerischen Darstellung sowie der nachfolgenden Beschreibung einer beson¬ ders bevorzugten Ausführungsform des erfindungsgemäßen Boden¬ belags; 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 tufted floor covering.
Die Zeichnung zeigt eine als Tuftinggrundgewebe ausgebildete Trägerbahn 10, welche im vorliegenden Fall aus Kunststoff- bändchen 10a hergestellt wurde und deren Wasserdurchläs¬ sigkeit auf die unterschiedlichste Weise sichergestellt wer¬ den kann, z. B. durch die Breite und Dichte der Kunststoff- bändchen 10a, d.. h. durch den Querabstand der die Kett- und Schußfäden bildenden Kunststoffbändchen voneinander. In die Trägerbahn 10 wurden im Tuftingverfahren Polelemente 12 ein¬ gebracht, 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 Trä¬ gerbahn 10 Löcher 10b erzeugt und durch diese Faserbüschel 14a hindurchgestoßen wurden. Durch das Aufnadeln der Faser¬ vliesschicht 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 Pol¬ elemente 12 gebildeten Polfäden gefördert werden kann. The drawing shows a carrier web 10 designed as a tufting base fabric, which in the present case was made from plastic tapes 10a and whose water permeability can be ensured in a wide variety of ways, e.g. B. by the width and density of the plastic tapes 10a, ie. 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 are located on the back of the carrier web 10, were introduced into the carrier web 10 using the tufting method. A nonwoven fabric layer 14 was then needled onto the carrier web 10 from below, as a result of which holes 10b were produced in the carrier web 10 and pushed through these fiber tufts 14a. By needling the fibrous nonwoven layer 14 not only was it attached to the carrier web 10, but the water permeability of the carrier web was also increased and at the same time it was ensured that water stored in the fibrous nonwoven layer 14 by a capillary effect caused by the fiber tufts 14a the area between the pile threads formed by the free end areas of the pile elements 12 can be conveyed.
