Process for making electrically conductive fibers |
摘要 |
Electrically conductive thermoplastic fibers are made by spinning a fiber having an electrically conductive sheath of thermoplastic polymer formulated with carbon black and a nonconductive core from the thermoplastic polymer; quenching the fiber after said spinning to a temperature below the melting point of the thermoplastic; drawing the quenched fiber at a draw ratio between about 2.0 and about 3.2; and, after drawing, relaxing the fiber at a temperature below the melting point of the thermoplastic but above its glass transition.
