Special aluminum foil materials are used as warp and weft threads, and the fabric is formed after high difficulty weaving with specific equipment. In terms of communication, this fabric forms a closed shielding room with surrounding metal, and isolates the metal between two space areas to control the induction and radiation of electric fields, magnetic fields and electromagnetic waves from one area to another. Enclose the interference sources of components, circuits, assemblies, cables or the entire system to prevent the interference electromagnetic field from spreading out; use shielding to enclose the receiving circuit, equipment or system to prevent them from being affected by the external electromagnetic field.
