The copper wires, 5% steel stainless-95% polyester blended yams, 10% steel stainless-90% polyester blended yams and 100% steel stainless blended yams in the structure of double plain inlaid knitted fabrics for designing electromagnetic wave absorbing screen, to improve absorbing screen by impedance match. In the study By experiment, the different effectiveness yams, the angle of samples' direction would influence the performance of attenuation effect. From the results, the performance of steel stainless blended yams screen is much more than copper wires screen. And the attenuation effect is increased with increasing the number of layers.
