In this research work, copper core yarns with cotton/polyester sheaths were produced by friction spinning machines and their woven fabrics were made by looms with varying fabric structures for electromagnetic (EM) shielding purposes. The effect of varying structures, varying materials, varying numbers of layers, core sheath ratio, and lay-up angle on EM shielding effectiveness were studied. The shielding effectiveness of copper core yarn fabrics was measured by using a Network Analyzer - EM shielding test (ASTM D4935-99) in the frequency range from 20—18,000 MHz.
