Description

Vandal resistant fabric.

The present invention relates to a fabric vandal-proof, which can be used to upholster seats for public or private transport vehicles, for public premises or Any other suitable application.

Background of the invention

Different types of vandal-proof fabrics, whose main characteristic is its great shear resistance

These vandal resistant tissues can be used in seats for public or private transport vehicles, in public places, such as in cinemas and theaters, or in the Home textiles, such as awnings.

One type of these vandal resistant tissues it comprises an upper layer that sticks to a formed lower layer by metallic threads. This type of fabric has the disadvantage that is very rigid, its subsequent being very complicated handling, for example to upholster a seat. This is because mainly to the fact that metallic threads are used with a diameter between 0.5 and 0.6 mm.

In some cases, these metallic wires can be replaced by threads of a very hard plastic material. Without However, the use of this plastic material does not solve the problem of tissue stiffness or resistance to vandalism.

Another drawback presented by the tissues Vandal-proof is that its manufacturing is expensive, since it has to separately manufacture the lower layer and the upper layer and subsequently they have to join each other.

Description of the invention

With the fabric of the invention are achieved solve the aforementioned problems, presenting other advantages that They will be described.

The vandal resistant fabric of the present invention  it comprises an upper layer and a lower layer, comprising the top layer natural or artificial fiber threads and the layer lower metal threads, and is characterized by the fact that said metallic threads of the lower layer are woven with the upper layer threads.

Preferably, the bottom layer also comprises natural or artificial fiber threads woven with threads metallic, the percentage of metallic threads being included with respect to the total of threads present in the lower layer between the 10% and 80%.

Said metallic threads are preferably of stainless steel, carbon steel or copper.

Advantageously, the diameter of each thread Metallic is between 0.05 mm and 0.35 mm.

Said metallic threads may be woven with the threads of the top layer by shedding, double shedding, jacquard, double jacquard or flat.

In addition, the metallic threads of the lower layer They are weft and weft.

If desired, said metal wires may be  coated, preferably by cotton or wool threads.

The vandal resistant fabric of the present invention  It presents a great resistance to the cut and, at the same time, it is very flexible, facilitating its handling and the upholstery of seats public transport vehicles.

Another advantage of the fabric of the present invention is that it forms a barrier against fire.

In addition, the fabric of the present invention can  manufactured at a reduced cost, compared to fabrics currently known vandal-proof, since the upper layers and Lower not be glued after manufacture, but the fabric between the two is made during its manufacture.

Brief description of the drawings

For a better understanding of how much has been exposed Some drawings are accompanied in which, schematically and only to non-limiting example title, a case study of realization.

Figure 1 is a schematic view in perspective of the fabric of the present invention, the layer being superior partially withdrawn; Y

Figure 2 is a schematic plan view of the metallic threads that form the bottom layer.

Description of a preferred embodiment

As can be seen in Figure 1, the vandal-resistant tissue of the present invention, identified in general by reference number 1, it is formed by two layers, a top layer 2 and a bottom layer 3 woven between yes.

The top layer 2 is conventional and is formed by threads of natural or artificial fibers, while the bottom layer 3 comprises metallic threads 3a, 3b and threads of natural or artificial fibers (not shown in the figure 2).

It should be noted that these layers are woven each other, that is, the metallic wires 3a, 3b are also fabrics with the threads of the top layer 2.

The metallic threads are weft in frame 3a and  Warp 3b, as can be seen in Figure 2.

The percentage of metallic threads 3a, 3b with respect  the total number of threads present in the lower layer 3 is comprised between 10% and 80%, depending on the characteristics that are They want to get.

Said metallic wires 3a, 3b may be of stainless steel, carbon steel or copper, although preferably They will be made of stainless steel.

The diameter of each metallic wire 3a, 3b is between 0.05 mm and 0.35 mm, that is, they are of a diameter inferior to the usual metallic threads used in fabrics Vandal-proof, which is usually 0.5-0.6 mm.

Said metallic threads 3a, 3b are woven with the threads of the top layer 2 in any suitable manner, such as for example by openwork, double draft, jacquard, double jacquard or flat.

If desired, said metal wires 3a, 3b they may be coated, for example by cotton threads or wool.

As stated above, the tissue of the The present invention is very flexible, compared to tissues conventional vandal-proof, and forms a barrier against the fire.

Although reference has been made to a concrete embodiment of the invention, is evident to an expert in the matter that the described vandal tissue is susceptible of numerous variations and modifications, and that all the details mentioned can be substituted by others technically equivalent, without departing from the scope of protection defined by the attached claims.
