Une première buse est montée à l'intérieur de la seconde buse et une des buses est reliée à un réservoir dans lequel se trouve un polymère et l'autre buse est reliée à un réservoir dans lequel des particules électroconductrices sont contenues dans une dispersion. Ladite dispersion dans laquelle sont contenues les particules électroconductrice est guidée hors du réservoir à travers une buse et le polymère est guidé hors du second réservoir à travers l'autre buse, de sorte qu'une fibre est obtenue après la sortie des buses, ladite fibre se composant d'une partie centrale et d'une enveloppe. La partie centrale est constituée par le polymère et l'enveloppe est constituée par les particules électroconductrices ou inversement. Les fibres ainsi formées ou une structure textile sont acheminées pour être soumises à un traitement thermique au cours duquel intervient une carbonisation.
