Definitions

  • the present invention concerns the technical field of nets for agriculture.
  • the present invention refers to the manufacture of insect nets used to cover cultivations and protect them from insects and/or aphids and their eggs.
  • a first known type of protection nets consists of nets arranged as a covering to ensure protection from hail, which are frequently used, for example, in vineyards and/or orchards.
  • Another type of protection nets of known type is constituted by the so-called insect nets, that is, nets made up of plaited and woven yarns, normally according to a weft and warp pattern, sufficiently close, on one hand, to prevent the passage of insects and/or aphids or their eggs that could reach the cultivations from the outside and, on the other hand, to allow the passage of light and of a sufficient quantity of air for the growth of the cultivations.
  • insect nets that is, nets made up of plaited and woven yarns, normally according to a weft and warp pattern, sufficiently close, on one hand, to prevent the passage of insects and/or aphids or their eggs that could reach the cultivations from the outside and, on the other hand, to allow the passage of light and of a sufficient quantity of air for the growth of the cultivations.
  • said nets In addition to ensuring protection from the outside, said nets also favour the so-called biological fight, meaning the fight against harmful insects through the introduction of other insects that are natural predators of the former and are not harmful to the cultivations.
  • the greenhouses provided with the nets described above prevent said predatory insects from flying out of them.
  • the nets described above are made of a polymeric material, in particular high-density polyethylene, preferably transparent and ensuring protection against UV rays.
  • Protection against UV rays can be obtained, as known, by spreading a thin protective film on the outer surface of the yarns that make up the net.
  • the net is transparent, even if it tends to lose part of its protective characteristics over time, due to the wear of said external layer.
  • the yarns can be manufactured by adding protective substances inside them, for example titanium dioxide, in which case the net can ensure protection against UV rays for a longer period, even though it becomes opaque and is not transparent any longer.
  • the manufacture of the nets includes the use of yarns with circular cross section, made of said polymeric material and plaited using the known weaving techniques, that is, arranging them in a first direction side by side and parallel to each other, and in a second direction side by side and parallel to each other, the second direction being preferably perpendicular to the first one.
  • Said nets are manufactured using frames that starting from the base material consisting of polyethylene yarns produce the fabric with weft and warp yarns.
  • the preparation of the warp consists in transferring the yarn, wound on bobbins or reels, to the special area of the frame where it is divided in two series, that is, the even and the odd.
  • the two series are divided placing one of them above and the other below, thus obtaining a passage through which the weft yarn is inserted.
  • the series exchange place meaning that the upper one moves down and vice versa, thus producing a crossing that locks the weft yarn.
  • the latter is then pushed against the preceding weft and the fabric is thus produced.
  • a first drawback posed by said nets of known type lies in that following the weaving process the weft and warp yarns often present imperfections in their configuration, and this means that the interlaced structure does not form a homogeneous pattern, so that in some areas the adjacent weft and warp yarns can be closer than in other areas, thus losing their parallel configuration.
  • Another drawback posed by said nets of known type lies in that during use the fabric of said nets can be subjected to deformations, so that the interlaced structure loses its homogeneity characteristics. This happens, for example, when some material, for example hail, accumulates on the net and its weight causes the fabric to deform due to the movement of the weft and warp yarns. Furthermore, said loss of homogeneity can occur during handling of the nets.
  • the dimensions of the fabric meshes exceed those expected and desired, meaning that insects and/or aphids or their eggs can pass through them or predatory insects can fly out of them in organic cultivations. Therefore, the net partially loses the required capacity to protect cultivations from the outside and/or from the inside.
  • said nets can wear out or break over time in the areas where said non-homogenoeus points are created, so that it is necessary to replace them.
  • the main object of the present invention is therefore to solve at least partially the problems that characterize the nets of known type.
  • the present invention is based on the general consideration that it should be possible to make the surface characteristics of a net for agriculture homogeneous and/or to improve them and/or to improve the aeration characteristics of the same by shaping the cross section of the yarns that make it up.
  • the object of the present invention is a net according to claim 1, meaning a net for agriculture comprising a plurality of interwoven warp yarns and weft yarns, at least one of said warp yarns or said weft yarns featuring a non-circular cross section.

  • the production process is advantageously simple.
  • the net is woven according to a leno weave pattern.
  • the net of the invention is an insect net.
  • the subject of the present invention is a yarn according to claim 14, meaning a weft or warp yarn for making nets for agriculture, said yarn featuring a non-circular cross section.

  • Figure 1 shows a net 1 according to a first preferred embodiment of the invention.
  • the net 1 is shown when used in a structure of the greenhouse type, that is, covering the agricultural culture to be grown and protected against insects and/or aphids and their eggs or against the escape of the predatory insects in cultivations adopting biological fight.

  • the net 1 is constituted by a plurality of warp yarns 2 and a plurality of weft yarns 3 arranged perpendicular to each other and interwoven so as to form a homogeneous fabric.

  • the warp yarns 2 in fact perform on the weft yarns 3 a continuous and constant alternating movement from top to bottom and, vice versa, the weft yarns 3 perform on the warp yarns 2 a continuous and constant alternating movement from top to bottom.
  • different weaving patterns are possible, intended to obtain different types of fabric of known type, like for example herringbone, sateen, leno weave, as shown in Figure 12, or fabrics containing also diagonal yarns, as shown for example in the embodiment illustrated in Figure 13.
  • the warp yarns 2 and weft yarns 3 are preferably made of transparent high- density polyethylene, coloured or neutral, preferably UV stabilized.
  • Protection against UV rays can be obtained, as known, by spreading a thin protective film on the outer surface of the yarns that make up the net.
  • the yarns can be manufactured by adding protective substances inside them, for example titanium dioxide, in which case the net is opaque and not transparent.
  • the insect net described herein preferably comprises a number of warp and weft yarns per square centimetre included between 6x6 and 23x14, preferably included between 16x10 and 22x12, and even more preferably equal to 20x12.

Said figure shows an enlarged detail of a crossing area with a first configuration of the crossing pattern between a warp yarn 2 and a weft yarn 3, and also shows the cross section of the warp yarn 2.
  • the star shape of the invention makes it possible to obtain a larger contact surface between the weft yarn 3 and the underlying warp yarn 2.
  • the warp yarn 2 and the weft yarn 3 come into contact in two distinct areas 7 and 8, as shown in Figure 5a, and not in a single contact area 7' as it happens in the known art. Therefore, the friction force that is generated between the warp yarn 2 and the weft yarn 3 at each crossing point is higher than in the known art and the arrangement of the crossings of the net 1 can be maintained more effectively.
  • the net 1 is more resistant and has a greater capacity to bear external deformation forces.
  • the net 1 is therefore homogeneous and its homogeneity lasts longer over time.
  • the net 1 of the invention alternatively offers an advantage in terms of either higher friction or better aeration compared to the nets of the known art.
