Abstract

The composite fabric comprises a load-carrying grid disposed between cloth and a flexible layer that are held to each other, the load-carrying grid which is at least two-directional being made up at least of warp thread and weft thread which are held to one another, the mesh defined by the grid having openings of area greater than the area of the gaps defined by the texture of the decorative cloth, the decorative cloth being held directly to the flexible sheet through the mesh of the load-carrying grid such that the fabric prevents outer ribs due to the thickness of the weft threads.

Claims

1. A composite fabric constituted by three superposed layers including a woven outer layer, the fabric comprising:

a grid that is two-directional at least, made up of held-together crossed threads of high tenacity, having a diameter greater than the thickness of the woven outer layer such that the fabric includes protecting ribs in the woven outer layer;

an abrasion-resistant outer decorative cloth; and

a waterproof flexible inner layer;

the decorative cloth being held directly to the flexible layer through the mesh of the grid.

2. A composite fabric according to claim 1, wherein at least some of the weft threads of the grid extend obliquely relative to the warp threads and relative to the threads of the outer cloth, constituting a polygonal mesh, said threads being held to one another.

3. A composite fabric according to claim 2, wherein the warp threads are made of polyester, while the weft threads are made of aramid.

4. A composite fabric according to claim 2, wherein the diameter of the weft threads is at least three times greater than the diameter of the warp threads.

5. A composite fabric according to claim 1, wherein the decorative outer cloth is of warp and weft structure being made of threads that withstand abrasion, such as polyester threads.

6. A composite fabric according to claim 5, wherein the warp threads of the grid are made of polyester, while the weft threads of the grid are made of aramid, and wherein the weft threads of the grid are inclined relative to the warp threads and/or the weft threads of the outer cloth.

7. A composite fabric according to claim 1, wherein the diameter of the threads of the grid is at least five times greater than the diameter of the threads of the decorative outer cloth.

8. A composite fabric according to claim 1, wherein the inner layer is bonded to the outer layer by adhesive, coating, or calendaring through the mesh of the grid.

9. Hand baggage made using composite fabric according to claim 1.

10. A garment comprising composite fabric according to claim 1.
