Abstract

By using commercial available electromagnetic interference (EMI) shielding fabrics, EMI shielding effectiveness(SE) and the physical properties were investigated. Thirteen specimens were chosen six fabrics were non-electrolytic plated with Cu, six plated with Cu+Ni and one plated with Ni, SE was measured by RF Impedance Analyzer HP4291A(Hewlett Co, Ltd)at the frequency of 100MHz-1.8GHz. The results showed that the commercial EMI shielding fabrics provided SE values over 30dB at the frequency of 100MHz-1.8GHz. Fabrics plated with Cu showed more effective shielding than those plated with Ni. The thickness of coating and fabric count were also influential factors on SE. Tensile properties were acceptable for lining fabrics but water vapor transport properties indicated that the better treatment condition were suggested to improve comfort properties.
