"Mesh fabric"

The invention relates to a mesh fabric with improved resistance to displacement. Lattice fabrics are sparsely adjusted fabrics in which the individual threads shift slightly against each other. In order to avoid these thread displacements as far as possible, it is customary to glue the fabric produced directly on the loom with suitable adhesives, for example with dispersion adhesives or PVC pastes.

The aim of the invention is to prevent the use of adhesives to avoid thread displacements entirely.

A mesh fabric made of warp and weft threads with excellent Resistance to displacement found, which is characterized in that the warp and / or weft thread layers are made of conventional Threads or threads obtained from foils made of the same or a different material than that of the usual threads are woven in or are twisted and / or doubled with the usual threads of the warp and weft thread layers.

The non-shifting mesh fabrics according to the invention have not been consolidated with the aid of adhesives, but contain them additional layers in the warp and / or weft thread layers obtained from foils, for example by cutting or splicing, Twisted or untwisted threads that prevent the actual lattice base fabric from shifting. As thread material for example, cotton, wool, polyamides, polyester or other natural fibers are used for the grid base fabric made of conventional threads or synthetic polymers are used, polyesters such as polyethylene terephthalate are preferred. Under the term "üblicjie

Threads "become mono- and multifilaments as well as fiber yarns Understood.

If the threads of the lattice base fabric and the foil threads are made of different materials, the individual thread types melt usually at different temperatures. A thread material is preferred in comparison to the lattice backing fabric lower melting foil thread material used; this makes it possible to use the mesh directly on the loom or afterwards in a separate operation by heating to a temperature above the softening or melting point of the film thread material, but to stick below the softening or melting point of the lattice backing thread material. If the lattice base fabric threads consist of high-melting material, the preferred film thread materials are polyvinyl chloride and polyolefins such as polyethylene, polypropylene are used.

The mesh fabrics according to the invention can also be made in such a way that the usual threads of the warp and weft thread layers with dm Foil threads are twisted and / or doubled.

The tissues according to the innovation are used after pasting, for example with polyvinyl chloride paste as tarpaulin.

Example:

Mesh fabric, consisting of 5 threads / cm in warp and weft

A mesh fabric consists of 10 threads / cm in warp and weft, and although alternating 2 threads made of polyethylene terephthalate (dtex 1100) and 2 polyvinyl chloride film threads (dtex 1100). It is a dense tissue that is no longer susceptible to displacement. If this fabric is pasted with polyvinyl chloride paste, so the polyvinyl chloride film threads connect with the paste or dissolve in it, and only the polyvinylchloride-glued remains Mesh fabric in the setting 5 threads / cm in warp and weft over. _

The accompanying drawing serves to explain the innovation according to the invention in an exemplary manner. In a grid fabric made of standard polyethylene terephthalate threads are in warp and
Weft woven in film threads made of polyvinyl chloride. There are 2 foil threads for every 2 threads of the base fabric.

In the drawing mean

1 warp threads made from standard polyethylene terephthalate threads

2 weft threads made of conventional polyethylene terephthalate threads

3 warp threads made of foil

4 weft threads from foils.
