“…Another research work was carried out to test the electro-thermal stability of silver yarn or silver-coated yarn by performing an oven aging test; the results found better electrical resistivity of silver yarn by showing a strong linear density. At a voltage of 9 V, that resistivity made the samples capable of obtaining higher temperatures [ 77 , 78 ]. Kexia et al [ 78 ] showed the relation of temperature and the resistance of wool and silver yarn made conductive electro-thermal knitted fabric ( Figure 4 B).…”

Intelligent textiles are predicted to see a ‘surprising’ development in the future. The consequence of this revived interest has been the growth of industrial goods and the improvement of innovative methods for the incorporation of electrical features into textiles materials. Conductive textiles comprise conductive fibres, yarns, fabrics, and finished goods produced using them. Present perspectives to manufacture electrically conductive threads containing conductive substrates, metal wires, metallic yarns, and intrinsically conductive polymers. This analysis concentrates on the latest developments of electro-conductivity in the area of smart textiles and heeds especially to materials and their assembling processes. The aim of this work is to illustrate a potential trade-off between versatility, ergonomics, low energy utilization, integration, and heating properties.

“…So the analytical equation could accurately model the electro-thermal characteristics of the thermal fabrics under an applied electric current and compute the temperature at a certain time. Li et al [20] evaluated the thermal-electrical stability of heating element with silver yarn. The results showed a larger linear density made the silver coated yarns better electrical resistance stability in the oven ageing experiment.…”

“…An infrared photographic instrument is used to measure the temperature variation on the electrically conductive yarns through which an electric current of different power flows. High temperatures increase the electrical resistance of the yarn [ 12 , 13 ]. Thermal cameras are also used, which take thermal photos through a textile circuit in which the electrically conductive yarns are under different voltage values [ 14 ].…”

In recent years, more and more researchers have been focused on electrically conductive textiles that generate heat or transmit electrical signals and energy to embedded electrical components. In this paper, the dissipation of heat due to the flow of electric current at given voltages is investigated, and at the same time it is determined how this heat affects the change in the electrical resistance of the electrically conductive yarn in the immediate surroundings. Three fabric samples were woven in a plain weave with three types of different electrically conductive yarns. Three electrically conductive yarns are woven in parallel in the weft direction and separated from each other by one polyester (PES) yarn due to electrical insulaton. Conductive yarns are electrically connected so that the outer yarns are used for heating by the flow of electric current at a certain constant voltage, and the central yarn is used only to measure changes in electrical resistance. When electrothermally conductive fabrics are subjected to certain voltages over time, experimental results have shown that resistance values increase over a short period of time and then gradually decrease, while the temperature gradually increases and stabilizes over time. Based on the analysis of the obtained results of the ratio between the values of applied voltage and temperature to the electrically conductive yarns, the value of thermal dissipation in conductive yarns can be calculated in advance depending on the applied voltage. Furthermore, the obtained results can be further used in applications where conductive yarns are used as heaters for realistic prediction of the obtained heat.
