Development of woven fabrics for electromagnetic shielding by quality function deployment application

In order to determine a proper product solution for achieving customer satisfaction and business goals, the entire steps of product development become more significant and complicated when utilizing external resources. The purpose of this work is to develop a woven fabric with a sufficient electromagnetic shielding performance. The concept of Quality Function Deployment (QFD) is used for the development process in which customer needs are translated into product properties and manufacturing process parameters. Two different counts of silver coated yarns are selected to produce various woven structures with plain weave. The electromagnetic shielding effectiveness of these fabrics is measured within the frequency range of 30 MHz to 3000 MHz, by means of a coaxial transmission set-up. The sample incorporating silver coated yarns at both entire warp and weft appeared to provide a shielding efficiency of 40-70 dB at various frequency ranges. © Chamber of Textile Engineers.
