Definitions

  • the present invention relates to a new type of openwork textile articles, produced on knitted looms; it also relates to a method for obtaining such an openwork article.
  • Knitted items e. discarded knits having a structure similar to a net are well known to technicians and have been the subject of numerous publications such as those which appeared in the review "Knitted Outerwear Times" of July 1968 pages 37 to 40.
  • the openwork structure according to the invention has the characteristics of having a width that is significantly greater - than the knitting width, which can reach two to three times the latter and this, while exhibiting the aforementioned properties.
  • the invention also relates to a method for obtaining such an openwork textile structure.
  • the openwork textile structure according to the invention is of the type constituted by a knitted fabric knitted made from yarns comprising a sheath of thermoplastic material, said sheath being partially melted and binding the threads together in the areas where they are in mutual contact and they are characterized by the fact that said knitted fabric is based on a weave comprising at least three bars and that the days are in the form of polygons regular, at least some of the sides of which are oriented at an angle with respect to the length of the structure and that the stitches of said knit trap a woven thread which extends in a substantially straight line parallel to the sides of the days formed.
  • the days of the structure have a hexagonal shape, which makes it possible to obtain practically identical resistances as well in the direction of the length, in the transverse direction and in the bias direction .
  • the days have a diamond shape, which gives perfectly balanced properties in the bias direction.
  • the invention also relates to a method for obtaining an openwork textile structure as defined above.
  • the loom is adjusted so as to have a decontextured structure, the stitches being loose, this being obtained, for example, by increasing the flow and / or the felling to a value higher than that used for the production of knitted nets proposed to date.
  • a Rachel loom of gauge 12 is used as a loom (that is to say having twelve needles in 25, 4 mm) the food threads being coated threads comprising. a core based on high tenacity polyester, 1100 decitex, coated with PVC at a rate of 30% polyester and 70% PVC by weight.
  • FIG. 1 illustrates a perforated textile structure in accordance with the invention obtained from a three bar weave knit.
  • the front bars (I and II) are threaded at disposal, a full, a vacuum, and work so as to form a net whose days are likely to be deformed if the knitting is pulled.
  • Such a type of openwork structure is not industrially usable taking into account this possibility of deformation.
  • This passage on the ream allows to give the knitting days a hexagonal, regular configuration.
  • the sides formed by the parts corresponding to the area A of FIG. 1 are arranged in the lengthwise direction of the fabric, while the sides corresponding to the areas referenced B and C are oriented at an angle relative to the length of the article. .
  • the wires of bar III which work in the weft on a needle are brought in a substantially straight line with respect to the sides of the formed day.
  • FIG. 2 is comparable to the previous example, but differs from it in that the weave ratio is 32 rows instead of 10.
  • An openwork textile structure is also obtained, the days having a hexagonal shape, the sides extending both in the long direction and at an angle and in which, the wires of the bar (III) which form the wefts, are substantially aligned with respect to the sides of said days.
  • FIG. 3 shows an openwork textile structure according to the invention produced in a four-bar weave.
  • the bars (I) and (II) form the openwork mesh structure of the knitted fabric while the bars (III) and (IV) are threaded at disposal and work in a woven weave.
  • this openwork textile structure appears, after widening and heat treatment, with diamond-shaped days, the weft threads extending substantially rectilinearly inside the knitted fabric. .
  • This example illustrated in FIG. 4 is a variant making it possible to obtain an openwork textile structure having diamond-shaped days.
  • the bars (I) and (II) form the mesh structure while the bars (III), (IV) (V) and (VI) work in a screened armor. After widening the knit and heat treatment, a perfectly stable and balanced article is obtained.
  • the articles obtained in accordance with the invention can find numerous applications and be used as is, for example, as a safety net, windbreak nets, fall protection, geotextile articles.
  • thermoplastic sheath makes it possible to obtain very good protection against bad weather, ultraviolet radiation,. Or even coloring effects.
  • the material used is wires of which only the outer periphery is based on a thermoplastic material
  • the heat treatment to which the article is subjected is such that there is only a partial melting of the thermoplastic sheath, and this in order to keep it a certain flexibility, it could be envisaged to carry out a treatment much more thermal depending on the desired stiffness.
