With the rapid development of technology in recent years, electrical and electronic devices have gained an important place in our lives. Electromagnetic waves and electromagnetic pollution that occur with the use of these devices are a serious problem. Shielding the electromagnetic waves is important for our health and safety. In our study, easy-to-use fabrics were designed and these fabrics can prevent radar imaging to electrical and electronic devices used for military purposes. Comez brand raschel knitting machine was used to produce mesh structure fabric that shields electromagnetic waves. Core yarns containing silver plated copper wire were used so that the fabric could shield electromagnetic waves. In order to add the specified core yarns into the fabric structure, designs were created with different knitting densities using the appropriate knitting structure. Then, the fabric samples were performed to measurements according to the ASTM D4935 test standard between frequencies of 15 MHz and 3000 MHz. According to the test results performed on the network analyser device, it was determined that the sample fabrics showed electromagnetic shielding effectiveness (EMSE) of approximately 10 dB in average at the specified measurement frequencies. This shows that the designed fabrics shield electromagnetic waves to a certain extent. It has also been determined that fabrics with more conductive content get higher EMSE values. Although EMSE results which performed according to ASTM D4935 by using network analyser as a test device are important, it is understood that higher performance results can be obtained by using different knitting structures with different amounts of conductive content for future studies.
