Abstract: A study on electromagnetic shielding effectiveness of copper core yarn knitted fabrics through Taguchi design and ANOVA has been reported. The copper is selected as the conductive filler to produce copper yarns for making knitted fabric. The electromagnetic shielding effectiveness of these knitted fabrics has been measured in the frequency range 20-18000 MHz using network analyzer equipment. It is observed that with an increase in tightness factors, wale density and course density, the shielding effectiveness increases. The interlock knitted fabric has better electromagnetic shielding effectiveness than rib and plain knitted fabrics. With an increase in copper wire diameter, a decrease in shielding effectiveness is observed.
