“…This was due to the highest electrical conductivity of silver and uniform distribution of the fibers. Although copper has higher conductivity than SS, due to lower strength of Cu than SS, its wires were broken during the manufacturing of hybrid yarn and fabrics that lead to discontinuity in the conduction path and hence lowered the SE [83]. Bahadir et al used stainless-steel wrapping polyester yarns to knit fabrics in different patterns like rib, panama, twill, and plain.…”

“…The shielding effectiveness was in the range of 30 to 60 dB at 30–3000 MHz [82]. The preparation of the commingled yarn and obtained hybrid yarns are represented in Figures 6 and 7 respectively [83]. Core-cover and plied yarns containing metallic wire-like steel wire and textile yarns (polyester) or filaments (polyester) can be manufactured by twisting.…”

The rapid proliferation of electronic devices and their operation at high frequencies has raised the contamination of artificial electromagnetic radiations in the atmosphere to an unprecedented level that is responsible for catastrophe for ecology and electronic devices. Therefore, the lightweight and flexible electromagnetic interference (EMI) shielding materials are of vital importance for controlling the pollution generated by such high-frequency EM radiations for protecting ecology and human health as well as the other nearby devices. In this regard, polymeric textile-based shielding composites have been proved to be the best due to their unique properties such as lightweight, excellent flexibility, low density, ease of processability and ease of handling. Moreover, such composites cover range of applications from everyday use to high-tech applications. Various polymeric textiles such as fibers, yarn, woven, nonwoven, knitted, as well as their hybrid composites have been extensively manipulated physically and/or chemically to act as shielding against such harmful radiations. This review encompasses from basic concept of EMI shielding for beginner to the latest research in polymeric-based textile materials synthesis for experts, covering detailed mechanisms with schematic illustration. The review also covers the gap of materials synthesis and their application on polymeric textiles which could be used for EMI shielding applications. Furthermore, recent research regarding rendering EMI shielding properties at various stages of polymeric textile development is provided for readers with critical analysis. Lastly, the applications along with environmental compliance have also been presented for better understanding.

“…According to the literature, 15,17,20,33 integrating the SS wire into the structure leads to an increase in their EMR shielding ability by the mechanism of reflection. The results of the experiment show that there is no dependence of shielding efficiency on the percentage of SS wire content.…”

Today we can’t imagine our life without electricity and technology, transport and television. In the information age, computers, the Internet, cell phones, and smartphones are helpers for everyday needs. However, our environment and comfortable living in it can be detrimental to our health. It is hard to realize the fact that such a global technical breakthrough has hit human health. Exposure to electromagnetic radiation could lead to changes in the structure of nerve cells and blood formulas, deformation of the circulatory system, pathology of the endocrine system, decreased immunity, and so on. Nowadays the development of innovative textiles with electromagnetic radiation shielding is a relevant topic that promotes the creation of a flexible protective screen for the human being and various electronic devices. Textiles themselves do not protect against electromagnetic radiation; however, the textiles can be successfully converted into protective material after changing the raw material composition, creating a new production process, or adapting technologies that can make them electrically conductive. Basic methods of textile producing such as weaving, knitting, non-weaving, or their combination can be used to make electromagnetic shielding fabric. In this study, the knitting on 8-gauge flat-bed machine has been chosen as main technology. The metal wire (stainless steel: 0.12 mm) is used separately or together with 10 × 2 tex cotton yarn. Two sets of samples with different interloopings are produced which differ by steel percentages and positioning in the structures. Electromagnetic shielding effectiveness of textile samples (dB) was measured according to ASTM 4935-10 on frequency range 30 MHz–1.5 GHz. It is concluded that the positioning of the metal components in the knitted structure is the main factor determining the shielding ability. The half Milano rib knitted structure demonstrates the highest shielding efficiency.

“…The EMSE values were measured for the electric field (30 Hz -6 GHz) and for the magnetic field (10 Hz -1 GHz) using isotropic E-field and H-field probes. Özkan studied the antimicrobial and EMSE properties of metal composite single jersey [18] and 1x1 rib fabrics [19,20]. EMSE of samples was measured according to the free space test method (0.8 -5.2 GHz).…”

The aim of this study is to investigate the influence of knitting structure and metal wire amount on the electromagnetic shielding effectiveness (EMSE) of knitted fabrics comparatively. Single jersey, single pique, weft locknit, and cross miss fabrics involving stainless steel or copper wires were produced on a flat knitting machine. A free space measurement technique was used for the EMSE measurements in an anechoic chamber. The variance analysis results of the EMSE values reveal that the effect of knitting structure, metal wire type, metal wire amount, and incident wave frequency is highly significant. It was observed that fabrics with tuck and miss loop structures had higher EMSE values than single jersey fabrics. It was found that single pique fabrics had higher EMSE values than single jersey fabrics that contain twice as much metal wire. It indicates that changing the knitting structure is more effective than changing the metal wire amount.
