Abstract:

In the research, The electromagnetic interferences (EMI) have drastically increased and can disrupt and reduce the life time and the efficiency of devices. Therefore, the electromagnetic shielding problem is become the important issue. In the research, Ni wire and Cu wire (Floodlit Enterprise Co., Ltd.) were used to make the Ni conductive composite yarn and Cu conductive composite yarn via an electrical covering machine. And the Cu conductive composite yarn was fabricated to the woven fabrics with the plain weaving. The test results revealed that the EMSE of the W/K/W complex fabrics have stable EMSE than the W/W/W complex fabrics when the laminated at the same direction. The W/90W/W complex woven fabrics were shown the best EMSE of 46.25 dB, which the test frequency is 1800 MHz.
