Investigation of electro-magnetic properties of knitted fabrics with combined electro-conductive yarns

The article is devoted to the investigation of electromagnetic properties of knitted fabrics for special purposes with the combined electro-conductive yarns. In the article main indices of physical-mechanical and conductive properties of the conductive yarns and knitted fabrics for special purposes are described. The results of experiments, determining influence of different weaves and physical-mechanical properties of knitted fabrics on their electromagnetic properties are described. The optimal weave was found which allows reaching of maximal shielding effect by frequency 2GHz with the maximal yarn density.
