Abstract
There are derivative many problems from electromagnetic (EM) wave radiation with the development of communication technique. To protect the human body from the EM radiation, in this study, the antibacterial nylon (AN)/ bamboo charcoal polyester (BC-PET)/ stainless steel wire (SSW) metal composite yarns was produced on a hollow spindling spindle machine. In this study, we used the SSW as the core yarn, the AN and BC-PET as the outer and inner wrapped material, respectively. The wrapped amounts were varied from 6.5-11 turns/cm. Then, the AN/BC-PET/SSW metal composite yarns were woven into knitted fabrics on a circular knitting machine. Moreover, we also investigated the electromagnetic shielding effectiveness (EMSE) and water evaporation rate of the fabricated metal composite knitted fabrics. Optimum EMSE –30dB was obtained at the incident frequency of 0.54GHz.
