Definitions

  • the invention relates to grid fabric, in particular as a floor grid for raising chickens, according to the preamble of claim 1.
  • the woven mesh For this purpose, it is known to coat the woven mesh with a PVC plastisol. This is done using an appropriate coating bath. For this purpose, the mesh fabric is drawn through the coating bath of predetermined viscosity filled with liquid plastisol. The liquid particles located in the immediate area of the warp threads and weft threads remain stuck here.
  • the coating thickness also depends on the given viscosity of the plastisol. To achieve the required stability Achieving physical properties is therefore necessary under the existing conditions a double coating. Although the viscosity of the plastisol could be increased, the coat thickness per coat could be increased. However, tests have shown that this can lead to an undesirable displacement of the pre-woven lattice fabric.
  • a disadvantage of the mesh fabric according to DE-OS 41 23 055 is the requirement of multi-stage impregnation in order to coat the threads as a whole.
  • the mesh fabric can also be wrapped in one step in order to connect the threads so that they cannot move.
  • lattice structures are not suitable for use as a rearing grid in chicken coops, since experience has shown that the plastic coating becomes too thin and thus easily destructible with only one-stage impregnation.
  • the advantages of the invention are that, with improved constancy of the grid size, an additional internal Closer cohesion between warp threads and weft threads ensures that additional work steps for coating are saved, and that the required layer thickness can nevertheless be achieved.
  • the so-called wrap-around warp thread fixes the crossing points between the warp thread bundle and the weft thread bundle that are affected by the wrap.
  • the loop-rotating warp thread wraps around each crossing point with full integration of the respective weft bundle.
  • Each weft bundle is completely constricted between the warp bundle and the loop-rotating warp thread.
  • at least one of the warp threads is guided in such a way that it changes in a zigzag shape from one crossing point to another crossing point from one side of the warp thread bundle to the opposite side of the warp thread bundle, but at the same time completely encompasses the weft thread bundle and with it - loops.
  • the respective bundle of threads (warp bundle / weft bundle) is drawn together at the crossing points and the two bundles of threads wrapped around one another under the predetermined tension conditions of the wrapping-rotating warp thread, so that a relatively slip-proof cohesion is ensured at the crossing points .
  • the cohesion is so great that the lattice fabric produced in this way can be passed through a PVC plastisol of considerably high viscosity without the crossing points between the weft bundles and the warp bundles being able to shift against one another.
  • the viscosity is adjusted in such a way that the liquid remaining on the lattice fabric has a layer thickness which can withstand the chemical and technical requirements. This layer thickness is already applied in one operation.
  • the strength of the lattice structure can be significantly increased with features 1.2.
  • the use of an emulsifier-free PVC in conjunction with a plasticizer based on alkyl sulfonic acid ester contributes to a considerable improvement in dimensional stability of the mesh fabric.
  • Plasticizers of this type can be obtained commercially, for example, under the name Mesamol II.
  • the use of plasticizers of this type additionally creates a continuously smooth surface of the PVC sheathing because, surprisingly, the combination of PVC with such plasticizer has shown that the plastisol has a significantly improved self-venting behavior.
  • the surfaces of the casing are particularly smooth and free from microscopic notches. This increases not only the strength but also the abrasion resistance in connection with a low tendency to contamination.
  • Figure 1 is a mesh fabric according to this invention.
  • FIG. 2 shows an enlarged detail from a mesh fabric according to FIG. 1;
  • Fig. 3 shows a coated mesh.
  • Such a lattice fabric 1 consists in each case of a bundle of threads 2 for the weft threads 4 or the warp threads
  • the chain is a multifilament yarn, preferably a polyester yarn.
  • the polyester yarn is very strong.
  • the weft threads are likewise a multifilament yarn, likewise high tenacity, preferably polyester yarn. As can be seen, a weft thread bundle is formed in each case
  • the mesh size is, for example, 1 centimeter
  • the fabric thus produced must be made using a PVC Plastisol 7 coated and fixed in the process.
  • the individual filament bundles are encased in such a way that each individual filament lies completely within the plastisol 7.
  • the crossing points 5 are also coupled to one another via the plastisol.
  • the plastisol has an extremely high film strength in order to stabilize all crossing points in such a way that the coated mesh provides a permanent floor for chicken rearing houses.
  • At least one individual warp thread 6 of the warp thread bundle 3 is guided in the manner of a zigzag in such a way that it alternates over the warp thread bundle 3 from the crossing point 5 to the crossing point 5 and then again runs underneath the warp thread bundle 3 and at the same time wraps each weft thread bundle 4 from the side opposite the warp thread bundle.
  • the wrap-around single thread 6 clamps the weft bundle 4 between itself and the warp thread bundle 3, at the same time changing the side of the warp thread bundle from crossing point 5 to crossing point 5, on which it approaches the previous crossing point 5. was led. In this way, the individual
  • Thread bundles 3, 4 are fixed against one another in the region of the crossing points 5 by the individual warp thread 6 and tied together.
  • the sheathing of the mesh fabric with an emulsifier-free PVC in combination with a saponification-resistant plasticizer based on alkyl sulfonic acid esters, enhances the stabilizing effect as a result of the features according to claim 1, characterized in that the strength properties of the plastisol so equipped additionally be used for the further stabilization of the lattice fabric.
  • the relatively early gelling behavior of such plastisol ensures that the plastisol penetrates completely into the bundle of threads 3, 4 while avoiding the formation of drops. In this way, the bundles of threads are completely and homogeneously embedded in the plastisol sheathing and protected within the lattice fabric in a uniform sheathing thickness.

Abstract

L'invention concerne un tissu réticulé (1) utilisé en particulier comme treillis de sol pour l'élevage de volailles, constitué de fils de chaîne (3) et de fils de trame (4) croisés en faisceaux, qui sont, après le tissage, revêtus d'une matière plastique molle leur conférant une résistance aux produits chimiques. Au moins un fil (6) du faisceau de fils de chaîne (3) est amené d'un point de croisement (5) à un autre (6) en zigzag, et, de façon alternée, sur le faisceau de fils de chaîne (5) et de nouveau sous le faisceau de fils de chaîne (3), chaque faisceau de fils de trame (4) étant simultanément guidé de façon à former une boucle, depuis le côté opposé au faisceau de fils de chaîne (3).
