ABSTRACT:
An electrically conductive fibre formed from a thermoplastic organic polymer and having a zero or positive temperature coefficient of resistance. It is produced by the sequential steps of embedding and/or dispersing electrically conductive carbon particles into an outer region of the fibre, removing at least some of any free, unadhered carbon particles, if any are present, from the surface of the fibre by washing, and heating the fibre to a temperature whereby its temperature coefficient of resistance becomes zero or is converted to a positive value.
