Abstract

An anti-vandalism layer, especially for application in vehicle seats, vehicle roofs, vehicle tarpaulins, tents, inflatable structures, wall facing, and similar objects having an incisible exterior layer and subject to vandalism, includes of a knit fabric having at least in part cut-resistant fibers such as aromatic polyamide fibers, gel-spun polyethylene fibers, or glass fibers is disclosed. In at least one thread system, the knit fabric contains a wire present in a thread system projecting from the surface of the knit fabric such that during subsequent gluing of the anti-vandalism layer to, for example, a textile flat structure, gluing tends to occur on this thread system.

Claims

1. A wire-containing knit fabric anti-vandalism layer, said knit fabric anti-vandalism layer comprising cut-resistant fibers, wherein at least one thread system of said knit fabric contains a wire;

wherein said wire is present in at least one thread system projecting from the surface of the knit fabric; and

wherein said wire-containing thread system projects from the surface of the knit fabric in a manner such that during subsequent gluing of the anti-vandalism layer to an exterior layer the gluing occurs on the projecting wire-containing thread system.

2. The anti-vandalism layer in accordance with claim 1, wherein said cut-resistant fibers comprise aramid fibers, polyethylene fibers produced using a gel-spinning process, or glass fibers.

3. The anti-vandalism layer in accordance with claim 1, wherein said knit fabric is a warp knit fabric.

4. The anti-vandalism layer in accordance with claim 1, wherein said knit fabric is a Raschel fabric.

5. The anti-vandalism layer in accordance with claim 1, wherein said knit fabric is a crochet galloon fabric.

6. The anti-vandalism layer in accordance with claim 1, wherein said wire present in at least one thread system has a diameter of from 0.1 to 2.0 mm.

7. The anti-vandalism layer in accordance with claim 1, wherein said wire present in at least one thread system has a diameter of from 0.2 to 0.6 mm.

8. The anti-vandalism layer in accordance with claim 1, wherein said wire present in at least one thread system has a corrugated or spiral shape.

9. The anti-vandalism layer in accordance with claim 1, wherein said wire present in at least one thread system is sheathed in a knit fabric made from textile yarn.

10. The anti-vandalism layer in accordance with claim 1, wherein said wire present in at least one thread system is enveloped by a readily fusible polymer.

11. The anti-vandalism layer in accordance with claim 1, wherein said wire present in at least one thread system is enveloped by a readily fusible polymer and sheathed in a knit fabric made from textile yarn.

12. A vehicle seat comprising the anti-vandalism layer in accordance with claim 1.

13. A sliding roof for motor vehicles or a convertible top comprising the anti-vandalism layer in accordance with claim 1.

14. A protective layer under a tarpaulin for trucks or other commercial transport vehicles comprising the anti-vandalism layer in accordance with claim 1.

15. A protective layer under a woven fabric or other flat structure for tents or inflatable structures comprising the anti-vandalism layer in accordance with claim 1.

16. A protective layer under an exterior layer in wall facing such as impact pads or in similar wall, floor, or ceiling protective facing comprising the anti-vandalism layer in accordance with claim 1.

17. The vehicle seat in accordance with claim 12, wherein said anti-vandalism layer is under an exterior material and said exterior material is glued to said anti-vandalism layer at said wire-containing thread system projecting from the surface of the knit fabric.

18. A tarpaulin for trucks or other commercial transport vehicles, wherein said tarpaulin contains, under the actual tarpaulin layer made from woven fabric or another flat structure, at least one anti-vandalism layer in accordance with claim 1.

19. An impact pad for sports facilities or public transportation, or protective facing of ceilings, walls, or floors, wherein said impact pad or said protective facing contains, under the exterior layer, at least one anti-vandalism layer in accordance with claim 1.

20. The anti-vandalism layer in accordance with claim 1, wherein said fabric weight per unit area is from 100 to 2,000 g/m².

21. The anti-vandalism layer in accordance with claim 1, wherein said gluing is linewise.
