Conductive Yarn

This study aims to develop conductive textile materials using a polyester textile yarn by applying a knife coating method and pre-treatment of a tip-cylinder plasma electrode. In this research, carbon ink was coated on polyester staple yarn which was given a pre-treatment with a plasma generator and coated with the knife coating method. The electrical conductivity of conductive yarns produced from this study was divided into two types, as yarns without plasma treatment and with plasma treatment with a ratio of water and carbon ink concentrations of 1:1 and 2:1. The results of the electrical conductivity with plasma treatment and the concentration of carbon ink and water of 1:1 and 1:2 were 69005 (Ωm)-1 and 50144.25 (Ωm)-1, respectively, while the results of the electrical conductivity for threads with concentrations of carbon ink and water of 1:1 and 1:2 without plasma treatment were 18197.64 (Ωm)­‑1  and 8873.54 (Ωm)-1, respectively. The results showed that the concentration of carbon ink and water and plasma treatment affected the conductive value of the yarn. The results also showed that the presence of plasma pre-treatment improved the coating process of conductive ink on the yarn.Keywords: carbon ink; conductive yarn; plasma; textile A B S T R A KPenelitian ini bertujuan untuk mengembangkan bahan tekstil konduktif menggunakan benang tekstil poliester dengan mengaplikasikan metode knife coating dan pre-treatment plasma elektroda tip-cylinder. Pada penelitian ini dilakukan pelapisan dengan tinta karbon pada benang poliester stapel yang diberi perlakuan awal dengan plasma generator dan dilapisi dengan metode pelapisan knife coating. Konduktivitas listrik benang konduktif yang dihasilkan dari penelitian ini dibagi menjadi dua jenis, yaitu benang tanpa perlakuan plasma dan dengan perlakuan plasma dengan perbandingan konsentrasi air dan tinta karbon sebesar 1:1 dan 2:1. Hasil konduktivitas listrik dengan perlakuan plasma dan konsentrasi tinta karbon dan air sebesar 1:1 dan 1:2 masing-masing adalah 69005 (Ωm)‑1 dan 50144,25 (Ωm)-1, sedangkan hasil konduktivitas listrik untuk benang dengan konsentrasi tinta karbon dan air sebesar 1:1 dan 1:2 tanpa perlakuan plasma masing-masing adalah 18197,64 (Ωm)-1 dan 8873,54 (Ωm)-1. Hasil penelitian menunjukkan bahwa konsentrasi tinta karbon dan air serta perlakuan plasma berpengaruh terhadap nilai konduktivitas benang serta adanya pre-treatment plasma dapat meningkatkan proses coating tinta konduktif pada benang.Kata kunci: benang konduktif; plasma; tekstil; tinta karbon

This article reviews the preparation, development and characteristics of conductive polymer-based electro-conductive textile composites for electromagnetic interference shielding. Modification of ordinary textile materials in the form of electro-conductive composites makes them suitable for this purpose. Various metallic and non-metallic electro-conductive textiles have been explored here as the material for electromagnetic shielding. Different approaches of preparing textile electromagnetic shield have been described here. Recent advancements of application of conductive polymers in the field of textile electromagnetic shielding are described. Conductive polymer-coated textile materials showed superior electrical property as electromagnetic shield. Different methods of applications of conductive polymers onto textile surface are described here with their relative merits and demerits. Different conductive polymer-coated woven and nonwoven fabrics prepared by various researchers for electromagnetic shielding are taken into account. The effects of different process parameters of polymer processing on electromagnetic shielding are described.

Purpose – Flexible light-emitting textile display is designed with floats for electronic elements covering and electronic contacts insulation what at the same time provides an opportunity to develop aesthetic design of the display in the single piece construction of material. The paper aims to discuss these issues. Design/methodology/approach – Display consists of interwoven electrically conductive yarns, non-conductive yarns and SMD LEDs connected to conductive yarns. Industrial jacquard weaving machine have been used, weave patterns were designed in PC-Edit software. Findings – Weave can be used as a tool to build and evolve electrotextile. Exploring weaving techniques and perceiving electronic circuit as a weave pattern, new approaches can be developed in electrotextile design field. Research limitations/implications – Connections of electronic elements and conductive textile materials still is actual problem what should be explored in further research. Practical implications – Flexible light emitting textile display can be used as output interface integrated into communication clothing by representing different animated images directly on clothing. Display also can be used for accessories, room and auto interior etc. applications. Originality/value – Paper describes method of light source integration directly into textile structure, combining functional and visual design of textile display.

Abstract The paper presents a synthesis of the research performed on the electromagnetic properties and characterization of textile and non-textile materials with applications in shielding and protection from the electromagnetic field. The composite structures of functional textiles intended for protective clothing or general applications for electromagnetic immunity are presented and characterized. There are analyzed composite textiles with amorphous, ferrous or non-ferromagnetic metallic threads manufactured by means of woven and knitting classical technologies as well as materials using non-metallic, electrically conductive powders. The properties of the plain jersey, rib jersey, full and half cardigan fabric, Milano rib, are presented, too. Besides textiles, there are also characterized some composite and non-composite structures using metallic yarns and carbon powder. Another direction of interest relates to the use of textile materials with amorphous metal structure with the scope of achieving a more efficient protection to the electromagnetic fields used in cellular systems and Wi-Fi networks. In addition, a comparative analysis of the methods of characterization of composite structures is made.
