Abstract: Thermal properties of conductive nanocomposite core-shell filament yarns have been investigated as a structure of a textile for the purpose of generating heat from an electrical power source. A fine copper monofilament is coated with a composite of polypropylene and various filler content of copper nanoparticles by an injection molding process to study the thermal properties of yarn as a function of filler shell content. Electrical analogy of Fourier’s law in thermal circuit has been used for development of a theory for thermal parameters. Then theoretical approaches are compared with modeling results obtained by ANSYS software and experimental results. Results reveal that although increase in filler content causes an increase in electrical and thermal conductivity of composite shell of yarn, heat generation in shell is negligible compared to that in core. Furthermore, results reveal that optimum value of filler fraction for desirable heat transfer is achieved at = 0.065.
