Notes:
It is demonstrated that continuous filaments of rapidly crystallizing polymers, such as polyethylene and polypropylene, can be spun from the melt using an electric field as the only driving force. The molten polymer is fed into a metallic capillary forming a hemispherical drop at the end of the orifice. An electrical field is applied between the capillary and a conducting plate held perpendicular to the axis of the orifice. Above a critical field intensity a fine continuous jet of molten polymer is drawn; rapid crystallization ensues and a continuous fiber is formed. For fibers spun in an uncontrolled thermal environment, corresponding to ambient air temperature, and at electric field intensities of 6 and 7 kV cm-1, the properties are typically those of unoriented or slightly oriented polyolefin fibers, such as would be obtained in a conventional fiber spinning process.
