Abstract

Les fils ou fibres selon l'invention présentent une gaine constituée de polytétrafluoroéthylène finement divisé, d'un pigment conducteur de la chaleur, comme le noir de fumée ou le graphite, et d'un liant (1 = fil; 2 = gaine). Ces fils ou fibres présentent un titre de 500 à 20 000 dtex de préférence de 10 000 à 20 000 dtex. Conductibilité thermique améliorée.
