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.
