In this paper, the surface area of coated polymer-based textiles, i.e., copper and nickel plated woven polyester fabric, copper and acrylic coated woven polyester fabric, and copper and acrylic coated non-woven polyamide fabric, is investigated. In order to evaluate the surface area of the woven fabrics, Peirce’s geometrical model of the interlacing point and measurement using an electron microscope are used. Non-woven fabrics are evaluated using an optical method, handmade method, and MATLAB functions. An electrochemical method, based on the measurement of the resistance between two electrodes, is used for relative comparison of the effective surface area of the coated woven and non-woven fabrics. The experimental results show that the measured and calculated warp lengths do not differ within the standard deviation. The model for the surface area evaluation of the Pierce’s geometrical model for monofilament (non-fibrous) yarns is extended to multifilament yarns and to a uniform sample size. The experimental results show the increasing trend of surface area evaluation using both modeling and electrochemical methods, i.e., the surface area of the copper and acrylic coated woven Polyester fabric (PES) is the smallest surface area of investigated samples, followed by the surface area of the copper and acrylic coated non-woven fabric, and by copper and nickel plated woven PES fabric. These methods can be used for surface area evaluation of coated polymer-based textiles in the development of supercapacitors, electrochemical cells, or electrochemical catalysts.

“…4 One of the applications of electrically conductive textiles that is gaining a great deal of attention is the development of fabrics that shield objects or bodies from undesirable electromagnetic (EM) fields. 5,6 The demand to limit nonionizing radiation generated by special devices, such as cellphones, radars, wireless routers, and diagnostic devices, which are frequently found in homes, vehicles, planes, and boats, 7 has become essential. Each of these applications requires certain levels of electrical conductivity.…”

The development of textiles with the ability to shield an electromagnetic field is still of great interest, and the influences of the construction parameters of woven fabric (weave, input fibrous material composition, three-dimensional (3D) construction) on the resulting electromagnetic shielding efficiency have still not been sufficiently investigated. The main goal of this study is therefore to analyze the weaves of special electrically conductive woven fabrics and evaluate their impact on electromagnetic shielding effectiveness (SE) using statistical methods. Here, the interlacing structure cells of woven fabric are newly used to describe the weave. The results confirmed that the proposed theory of the interlacing of woven fabric is satisfactory for evaluating and, especially, for prediction of the SE of electromagnetic shielding woven fabrics. For this study, the input yarn (made from a mixture of traditional and extremely thin discrete stainless steel fibers) is used for the production of 21 types of dobby woven fabrics with different weaves and its SE was analyzed using the coaxial transmission-line technique. This contribution can be used as theoretical guidance for the construction, design, and production of special woven fabrics (dobby and jacquard pattern) with controlled SE.
