Multilayer textile article with an inner heating layer made of an electrified fabric, and respective manufacturing process

A new and innovative textile article (10, 10-1; 10-2; 10-3; 10-4), in the form of a heating multilayer sheet or fabric, exhibiting improved heating capacity and transmission of heat to the outside, comprising: at least one textile heating layer (10d) associated with an electrical resistance (R) adapted to be powered with an electric current (I) for generating by joule effect heat (C); and at least a reflective layer (10c) which is arranged adjacent to the heating layer (10d) to receive and reflect to a determined side, i.e. the front side (10"), of the fabric article (10, 10-1; 10-2; 10-3; 10-4) the heat generated by the heating layer (10d), wherein the heating layer (10d) in turn is made from a fabric that incorporates in its textile structure, as electrical resistance (R) for the generation of heat, a yarn or thread (F), for example in form of a serpentine, consisting of carbon fibers (CF). The heating multilayer textile article (10), in its various embodiments (10-1; 10-2; 10-3; 10-4), may also comprise ot
