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.
  • 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.
  • JP A-51-47165 provide a method for manufacturing an artificial turf which comprises a double fabric structure incorporating flat pile yarns. According to JP A-51-47165 , the surface of the base fabric is fully and efficiently covered by the pile yarns and a better appearance and cushion similar to the natural turf are realized in spite of that the mass thereof is relatively small.
  • Product leaflet Textile Industry SRX82 Van de Wiele, July 1985 describes a synthetic grass obtained by face-to-face weaving method and comprising a ground fabric and a number of plastic blades of grass protruding from the ground fabric which are tied up into the ground fabric e.g. by means of a W weave.
  • 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 of a pile burl, and at least three weft yarns between the pile legs of successive pile burls.
  • 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 of a pile burl of a plastic blade of grass 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, and at least three weft yarns between the pile legs of successive pile burls.
  • 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).
  • the method according to the invention offers the following advantages:
  • the purpose of the method is to produce an artificial turf as described above.
  • 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). In the case of the artificial turf illustrated in figure 3 , 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. Furthermore, 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.
