A process for producing sheath-core type electrically conductive synthetic composite filaments, which comprises simultaneously melt-extruding in a sheath/core filament configuration an electrically conductive core composition of a thermoplastic synthetic polymer containing an electrically conductive carbon black dispersed therein and a non-conductive sheath composition of a thermoplastic fiber-forming synthetic polymer, and taking up the extruded sheath-core type synthetic filaments at a take-up speed of at least 2,500 meters per minute; and an electrically conductive sheath-core type synthetic filament having a polyamide sheath. |
