Definitions

• 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.
• 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 of goods 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.
• 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.
• 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.
• 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 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.
• 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 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.
• 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.
• the need for the fibrous material web to increase the water permeability of the carrier web is also provided.
• 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.
• 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.
• 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.
• 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.
• the fibrous nonwoven layer 14 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.
