Definitions

  • the present invention relates to a new type of material based on a nonwoven textile web usable as reinforcement for waterproofing coatings consisting of a support embedded in a bitumen composition.
  • a nonwoven textile web usable as reinforcement for waterproofing coatings consisting of a support embedded in a bitumen composition.
  • the invention will be described for such an application, but it is obvious that this is not limiting and that, possibly, such a material could be used in other applications, for example as a support for coating or reinforcing reinforcement of resin-based laminated articles.
  • Sealing screeds made of a textile reinforcement printed with bitumen are well-known articles and are used in many fields, in particular in the building industry.
  • the invention therefore relates to a material based on a nonwoven textile web usable in particular as a reinforcement for sealing coatings, said material being of the type constituted by a fibrous web associated with a textile grid, and it is characterized by the fact that the textile grid is embedded inside the fibrous structure whose fibers are entangled through the interstices of said grid and protrude on each side of the latter, the entanglement of fibers through the reinforcing grid being obtained by the action of jets of fluid (air or water) which entrain the fibers through the grid and distribute them on either side of the latter without damaging it.
  • the connection between the fibrous structure and the reinforcing grid is obtained mechanically, by entanglement and not by gluing as in most of the previous solutions.
  • the reinforcing grid and the fibrous structure entangled with said grid can be based either on textile materials of the same kind, or based on textile materials of different nature.
  • the grid may also be based on glass fibers, polyester, a mixture of these fibers.
  • the invention also relates to a process allowing the production of such materials, this process consisting in superimposing a textile grid (woven or non-woven) with a non-woven fibrous web, produced by dry process (carding in particular), the process according to the invention characterized by the fact that the complex thus formed is subjected to the action of jets of fluid (air or water) acting on the superposed materials at least on the side of the nonwoven fibrous web, the jets entraining the fibers of this tablecloth through the grid and distributing them on either side of the latter.
  • the fibrous structure based on polyester fibers is intimately entangled with the textile grid by subjecting the two superimposed materials to the action of jets of fluid (water) acting on the polyester web.
  • the association of the two layers is carried out, for example, on a conventional type of material such as that marketed by the company "HONEYCOMB SYSTEMS, INC” commonly designated by technicians by the expression “hydraulic intermixing”.
  • a complex according to the invention is produced from a grid and a veil of fibers similar to Example 1 but, when the entanglement is produced, the grid based on glass threads is inserted between two veils based on polyester fibers, the assembly being subjected to the action of jets of fluid on the two opposite faces.
  • a complex is obtained in which the glass sheet is embedded inside the fibrous structure based on polyester fibers, the latter being intimately entangled, covering the grid, and being distributed on either side of the latter. regularly.
  • a complex is produced in accordance with the invention by associating with a glass grid of the type of examples 1 and 2 one or two veils based on glass fibers having a length of 50 mm and a diameter of 14 microns and weighing 50 g / m2.
  • All the materials described above can be easily stored and handled and, after coating with a layer of bitumen, make it possible to obtain complexes having excellent characteristics of dimensional stability and resistance to static and dynamic punching.
  • the fibers being oriented in all directions and over the entire thickness of the complex, this facilitates impregnation with bitumen or resin in the case of laminates, and gives a very homogeneous finished material.

Claims (10)

1. Material auf der Basis eines nichtgewebten Textilvlieses, das insbesondere als Verstärkungsstruktur von Abdichtbelägen verwendbar ist, die aus einem mit einem textilen Gitterwerk asoziierten Faservlies gebildet sind, dadurch gekennzeichnet, daß das textile Gitterwerk im Innern einer Faserstruktur vollständig eingebettet ist, wobei die Fasern durch die Gitteröffnungen des Gitters hindurchreichend wirr durcheinander angeordnet sind und sich beidseits des letzteren erstrecken, wobei die wirre Anordnungen der Fasern durch das Verstärkungsgitter hindurch durch die Wirkung von Fluiddüsen (Luft oder Wasser) erhalten wird, die die Fasern durch das Gitterwerk hindurchfördern und diese beidseits des letzteren verteilen ohne diese zu beschädigen.
2. Material nach Anspruch 1, dadurch gekennzeichnet, daß das textile Gitterwerk ein nichtgewebtes Gitterwerk ist.
3. Material nach Anspruch 2, dadurch gekennzeichnet, daß das textile Gitterwerk auf der Basis von Glasfasern aufgebaut ist.
4. Material nach Anspruch 3, dadurch gekennzeichnet, daß das textile Gitterwerk auf der Basis von Polyester aufgebaut ist.
5. Material nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, daß die Faserstruktur auf der Basis von Glasfasern aufgebaut ist.
6. Material nach einem der Ansprüche 2 oder 3, dadurch gekennzeichnet, daß die Faserstruktur auf der Basis von Polyester aufgebaut ist.
7. Material nach einem der Ansprüche 2 oder 3, dadurch gekennzeichnet, daß die Faserstruktur auf der Basis einer Mischung an Glasfasern und an Polyesterfasern aufgebaut ist.
8. Material nach einem der Ansprüche 2 bis 7, dadurch gekennzeichnet, daß die Faserstruktur gleichermaßen einen geringen Anteil an Fasern aufweist, die Eigenschaften aufweisen, die sich bei einer späteren Behandlung zeigen.
9. Verfahren zum Herstellen eines Materials nach einem der Ansprüche 1 bis 8, bei dem ein textiles Gitterwerk (gewebt oder nichtgewebt), und ein nichtgewebtes, auf trocknem Wege hergestelltes Faservlies aufeinandergelegt werden, dadurch gekennzeichnet, daß man den so geformten Zusammenbau der Wirkung von Fluiddüsen unterwirft, die zumindest auf seiten des nichtgewebten Faservlieses auf das übereinandergelegte Material einwirken, wobei die Düsen die Fasern dieses Vlieses durch das Gitterwerk hindurchfördern und diese beidseits des letzteren verteilen.
10. Verfahren nach Anspruch 9, dadurch gekennzeichnet, daß man den Zusammenbau mittels Fluiddüsen einer zweiten Behandlung unterzieht, wobei diese auf der Seite einwirken, die der der ersten Behandlung gegenüberliegt.
