Abstract: A method for producing a continuous filament made up of nanofibers is disclosed. A ribbon-shaped nanofiber web is prepared by electrospinning a polymer spinning solution onto a collector 7 applied with a high voltage, the collector 7 consisting of (I) an endless belt type nonconductive plate 7a with grooves having a predetermined width (u) and depth (h) formed at regular intervals along a lengthwise direction and a conductive plate 7b inserted into the grooves of the nonconductive plate, and then the nanofiber web is isolated (separated) from the collector 7, focused, drawn and wound. A continuous filament (yarn) made up of nanofibers can be produced by a simple and continuous process by providing a method for continuously producing a filament (yarn) by an electrospinning technique without a spinning process. The focusability and the drawability can be greatly improved by orienting nanofibers well in the fiber axis direction.
