Based on the structure analysis of woven fabric composed of metal fiber, it is proved that metal fiber yarn forms an effective electromagnetic shielding structure. The bare copper wires were used to prepare the simulated metal fiber of fabric effective structural models. The arrangement, arrangement spacing and connected manner between the bare copper wires of the samples were different. The shielding effectiveness of these samples was tested by the shielding chamber method, and the frequency range was from 1 - 18 GHz. The results showed that arrangement spacing of the metal fiber is the key facto affecting shielding effectiveness. The shielding effectiveness of the sample with unidirectional arrangement of metal fiber is the same as that with the bidirectional arrangement, but the shielding effectiveness of the sample with unidirectional arrangement metal fiber has significant direction. With bidirectional grid, the grid size of the sample affects its shielding effectiveness. Under laboratory conditions, if the junction of the mental fiber is connectivity, the shielding effectiveness will be changed.
