ABSTRACT:
A multi-layer fabric having greatly improved tearing resistance is obtained for canopies and tarpaulins and the like by the provision of two-layers of a woven textile fabric positioned on either side of a deformable reinforcing layer formed from wires having a high mechanical strength. The textile layers are bonded to the deformable reinforcing layer by a layer of material having a modulus of elasticity in shear allowing it to break when a force is exerted on the reinforcing wires, thus permitting movement of the wires within the fabric without breaking under the action of the force. Adhesive bonding layers join the outer fiber woven textile material to each other and to the wire loop layer to form a unified fabric structure. Thus, when it is attempted to cut or tear the fabric with a sharp instrument drawn across the surface thereof, the looped wires are displaced and bear successively against one another offering increased resistance until they stop the knife without breaking or tearing further.
