Claims
- 1. A method for producing an electrically conductive conjugate fiber comprising a thermoplastic polymer as the sheath and a low-melting metal as the core, the method comprising:
- providing a fusion tank which contains a low-melting metal in a molten state;
- discharging molten metal from the fusion tank by the pressure or an inert gas to supply the molten metal to a conjugate spinning nozzle, the pressure of the inert gas being controlled so as to maintain a pressure variation of 0.1 kg/cm.sup.2 or less, the molten metal within said tank being maintained at an almost constant level; and
- spinning a conjugate fiber comprising a thermal plastic polymer as the sheath and the low-melting metal as the core from the conjugate spinning nozzle.
- 2. A method as claimed in claim 1, wherein the polymer has a melt viscosity of 3,000 to 8,000 poises at 300.degree. C.
- 3. A method as claimed in claim 2, wherein the polymer has a melt viscosity of 4,000 to 7,000 poises at 300.degree. C.
- 4. A method as claimed in claim 1, wherein the pressure variation is 0.05 kg/cm.sup.2 or less.
