Abstract: An unfinished reinforced multilayer fabric (11), able to produce a finished reinforced multilayer fabric (18) which includes an initial layer (12) of threads (13) parallel with each other, superimposed, with the interpositioning of a binding layer (14) on at least a second layer (12) of threads (13), these also being basically parallel with each other, where the threads (13) of the first layer (12) are set in various directions with respect to the threads (13) of the second layer (12) and the two layers (12) are also joined by a large number of binding threads (15), made of a thermoplastic, or thermosetting type material, or of a material which is water-soluble or soluble in a suitable solvent.
