CONDUCTIVE FABRICS COMPRISING ELECTRICAL PATHWAYS AND METHOD OF THEIR MANUFACTURE Russian patent published in 2013 - IPC D04H13/00 B05D7/00 B32B1/00 B32B5/26 

FIELD: textiles, paper.

SUBSTANCE: conductive material comprises a conductive nonwoven fabric containing conductive carbon fibers in an amount of 5-50 wt % in combination with cellulose fibers and/or synthetic fibers. The nonwoven fabric comprises conductive and non-conductive zones that contain sonicated sections. The conductive material is used in production of heating devices, electronic switches, electronic devices, RF modification devices. In the electronic switch the conductive nonwoven fabric is spaced from the opposite conductive layer and the electrical connection is formed between them when they are pressed to each other. The electronic switch is used in production of a garment, a glowing symbol. The electronic product comprises an outer surface intended for location of plurality of keys, a first conductive layer located under the keys, the second conductive layer, spaced from the first conductive layer, and in which when pressing one of the keys an electric connection is created between the conductive layers.

EFFECT: reduction of weight of the non-woven conductive fabric, increased strength of the multilayer flexible electronic device, reduction of the total resistance of heating devices.
