Definitions

  • the present invention firstly relates to an artificial turf comprising a ground fabric made from synthetic ground warp yarns and synthetic weft yarns and a number of plastic blades of grass protruding from the ground fabric in the shape of pile burls which succeed one another in the warp direction and which each comprise two pile legs. Secondly, the present invention relates to a method for producing artificial turf of this type.
  • the climatic conditions are not always suitable for natural turf; the load to which the natural turf is subjected (during sports events) damages the playing field, which makes it necessary to leave considerable intervals before using the playing field again;
  • plastic fibers blades of grass
  • carrier material in which the plastic blades of grass preferably protrude from the carrier material at right angles.
  • the plastic blades of grass are generally hard and smooth plastic fibers, such as polyolefins (polyethylene, polypropylene and mixtures) or polyamides.
  • the carrier material is a textile cloth through which the plastic blades of grass are tufted. This means that a plastic blade of grass is pushed through the cloth by means of a needle to form a loop. On the other side of the textile cloth, a hook takes over the loop which has been produced and takes this loop to the desired level.
  • the loop is then usually cut through, resulting in the formation of two upright blades of grass.
  • the process of tufting the plastic blades of grass currently has the limitation that not less than 120 tufts per meter can be produced in the tuft cloth direction so that there are sufficient loops on the hook and so that, when the subsequent tufts are produced, the pile of the previous loops is not pulled back resulting in very irregular pile or no pile at all. This makes it impossible to produce artificial turf with tuft densities below 10 000 tufts/m 2 having an even spacing between the various tuft rows.
  • the object of the invention is achieved by providing an artificial turf consisting of a ground fabric made from synthetic ground warp yarns and synthetic weft yarns and a number of plastic blades of grass protruding from the ground fabric in the shape of pile burls which succeed one another in the warp direction and which each comprise two pile legs, in which at least three and at most nine weft yarns are inserted between two successive pile legs.
  • the two pile legs of a pile burl are tied up around a different weft yarn which are both situated between these two pile legs.
  • the plastic blades of grass protruding from the ground fabric are tied up into the ground fabric by means of a W weave.
  • the part of the plastic blade of grass which runs on the back of the fabric does not run from one pile leg to the other pile leg on the back of the fabric, but is tied up over one or more weft yarns on the side of the artificial turf pile.
  • the plastic blade of grass is tied up over at least two weft yarns which are situated between the pile legs of this pile burl on the side of the artificial turf of the fabric. This is in particular achieved by means of a 5/12 W weave in which there are 5 weft yarns between the two pile legs of a pile burl.
  • the plastic blade of grass is tied up over three weft yarns which are situated between the pile legs of this pile burl on the side of the artificial turf of the fabric. This is in particular achieved by means of a 7/16 W weave in which there are 7 weft yarns between the two pile legs of a pile burl.
  • the pile legs of adjacent rows of piles are offset with respect to one another.
  • This is preferably achieved by means of a satin weave, thus resulting in a further improvement of the distribution of the pile burls. Examples thereof are: 5/12 W weave in satin 6; 7/16 W weave in satin 4; 7/16 W weave in satin 8.
  • This method makes it possible to produce the artificial turf in a more efficient manner for an even distribution than without this offset.
  • said turf is woven according to a face-to-face weaving method.
  • It is another object of the present patent application to provide a method for producing an artificial turf comprising a ground fabric and a number of plastic blades of grass protruding from the ground fabric, in which a bottom and a top fabric are woven according to a face-to-face weaving method, in which the fabrics are made from synthetic weft yarns, synthetic ground warp yarns and grass blade-forming pile warp yarns by means of which pile burls with in each case two pile legs are formed alternately in both fabrics, in which, in each fabric, each pile leg in a row in the warp direction is separated by at least three and at most nine weft yarns from the next pile leg of a plastic blade of grass in this row.
  • a pile burl is formed in the other fabric using the face-to-face weaving technique before the plastic grass blade yarn again forms pile in the one fabric. If the two pile legs of the pile burl in the other fabric are also separated by at least three weft yarns from one another, there are also at least three weft yarns between the pile legs of successive pile burls in the same fabric. (With 5/12 W weave, there are seven weft yarns inbetween; with 7/16 W weave, there are nine weft yarns inbetween). Compared to the known techniques for producing artificial turf, the method according to the invention offers the following advantages:
  • the plastic blades of grass (the consumption of which is nearly identical in both situations) in the artificial turf according to the invention are distributed over twice as many evenly distributed physical points, as a result of which the performance of the artificial turf improves for the same amount of material (this means that in order to achieve the same performance of the artificial turf, the pile burl density can be reduced which results in a lower consumption of plastic grass blade material);
  • the method according to the invention uses less material as the distance between the two pile legs of a pile burl is only half that of the distance between the pile legs during tufting, as a result of which the material consumption on the back is reduced;
  • relatively thick yarns with a relatively low pile burl density and if weaving is carried out at a consumption of pile material which corresponds to the consumption of pile material of tufted artificial turf said relatively thick integrally formed yarns will result in a better stiffness, a better resilience and a better roll of the ball than is the case when the pile legs of the tufts are placed next to one another.
  • the improved properties and equal consumption again result in less raw material being required in order to achieve the same performance of the artificial turf; -
  • the plastic blades of grass used are usually composed of several filaments which are bundled.
  • the relatively thick plastic grass yarn may be composed of relatively thick filaments of which fewer are ultimately required. This further increases the resilience and playing properties, as a result of which the material consumption can be reduced further while retaining the same playing properties.
  • the purpose of the method is to produce an artificial turf as described above.
  • figure 1 shows a diagrammatic representation of an artificial turf with tufted blades of artificial grass according to the prior art
  • - figure 2 shows a cross section through the artificial turf represented in figure l
  • figure 3 shows a diagrammatic representation of an artificial turf according to the invention.
  • the prior-art artificial turf pitches are composed of tufted artificial turf.
  • This known artificial turf as illustrated in figures 1 and 2, comprises a base fabric and a number of plastic blades of grass (5) protruding from this base fabric.
  • the plastic blades of grass (5) are connected to the base fabric (for example a textile cloth) by means of reciprocating tuft needles and hooks, onto which the tuft burls are transferred from the needles.
  • this known technique has the drawback that in each case two tuft legs (5) of a plastic blade of grass are positioned right next to one another, which indeed do not act a single blade of grass of double thickness due to the limited distance between them. This can be seen in figure 2.
  • the artificial turf (1) according to the present invention and as illustrated in figure 3 consists of a ground fabric and a number of plastic blades of grass (2) protruding out of the ground fabric in the shape of pile burls which succeed one another in the warp direction and which each comprise two pile legs.
  • the ground fabric consists of synthetic, moisture-resistant ground warp yarns and weft yarns (3).
  • tension warp yarns (4) in the ground fabric, which ensure that the weft yarns are layered, as well as binding warp yarns (not illustrated in the figure) which regularly intersect with each other, the weft yarns being situated between the intersecting binding warp yarns.
  • the invention is characterized by the fact that at least three and at most nine weft yarns (3) are inserted between two successive pile legs (2a).
  • five weft yarns (3) are inserted between two successive pile legs.
  • This is preferably achieved by means of the technique of the W weave in face-to-face weaving: this means that the plastic blades of grass consist of pile burls which each consist of two pile legs, with at least three weft yarns (3) and at most nine weft yarns being present between the pile legs and there also being at least five weft yarns and at most eleven weft yarns between the pile legs of successive pile burls.
  • Each pile leg (2a) is tied up around a different weft yarn (3a) which are both situated between the two pile legs.
  • the plastic grass blade section (2b) which connects the two pile legs to one another is tied up in the ground fabric over at least one additional weft yarn (3b) between the two pile legs.
  • the two pile legs (2a) of a tuft are separated from one another over a number weft yarns and therefore over a certain distance.
  • the pile yarn (the plastic blade of grass) then moves to the other fabric in order to also insert two pile legs (2a) in a W weave as a plastic blade of grass (2) and to return to the first fabric in order to insert two pile legs (2a) at a distance from one another as a plastic blade of grass (2), again in W weave.
  • the two pile legs together form one tuft (one blade of grass) in one location during tufting
  • the same amount of pile is produced in two locations which are a distance apart.
  • the two pile legs are also next to one another separated by one weft yarn, as a result of which the two pile legs are virtually next to one another and appear as a single blade of grass.
  • the method of the invention offers the same advantages as the prior art with respect to tufting, especially if the 1/2V technique is used for intermediate distances between the pile legs of more than 10 mm. Furthermore, only that part of the plastic blade of grass which runs between two upright plastic blades of grass of the same pile burl runs on the back of the fabric, while there is no material on the back between two upright plastic blades of grass from a different pile burl, thus resulting in a further reduction in the consumption of material.

Abstract

La présente invention concerne un gazon artificiel (1) ainsi qu'un procédé pour produire un gazon artificiel (1) comprenant un tissu de fond composé de fils de chaîne de fond et de fils de trame synthétiques et de plusieurs lames d'herbe en plastique (2) ressortant du tissu de fond sous la forme de nœuds de boucle qui se succèdent les uns sur les autres dans la direction de la chaîne et comprenant chacun deux ailes de boucle (2a), au moins trois et au plus neuf fils de trame (3) sont insérés étant deux ailes de boucle successives (2a). En particulier, chaque aile de boucle (2a) est enroulée autour d'un différent fil de trame (3), ces deux fils étant situés entre les deux ailes de boucle. Du fait que la distance entre les deux ailes de boucle d'un nœud de boucle est seulement la moitié de la distance entre les ailes de boucle au cours de l'opération de tufting, la consommation de matériaux en termes de fil de lame d'herbe en plastique sera considérablement réduite. En outre, un tel gazon artificiel (1) présente l'avantage que les nœuds de boucle et en particulier les lames d'herbe en plastique sont uniformément répartis à travers le tissu.
