摘要： A plurality of CNTs 10 are drawn out of VACNTs 2 so as to be continuous in lines and are bundled into a thread shape, and a temporary thread 11 bundled into a thread shape is temporarily wound on the first winder 12. The first winder 12 is then rotated about an axis along a feeding direction of the temporary thread 11 to twist the temporary thread 11 while the temporary thread 11 is fed from the first winder 12.

摘要： An object of the present invention is to prevent edge scraps from being generated when carbon nanotubes are drawn out, and to prevent generated edge scraps from being mixed in a carbon nanotube web. A method for drawing out a carbon nanotube web in accordance with an aspect of the present invention includes a hard-to-draw part forming step of forming grooves (11) each of which has a width that is smaller than a length of one CNT (2) in a CNT array (1) and forming hard-to-draw parts (12) which are formed in regions abutting on the grooves (11) and in which the CNTs (2) are difficult to draw out from the CNT array (1), and a drawing out step of drawing a CNT web (10) out from a region between the plurality of hard-to-draw parts (12) in the CNT array (1).

摘要： The method for producing a carbon nanotube twisted yarn includes preparing a vertically-aligned carbon nanotube that is disposed on a substrate and is aligned vertically to the substrate; drawing a plurality of carbon nanotube single yarns from the vertically-aligned carbon nanotube, and arranging the plurality of carbon nanotube single yarns in parallel to prepare a carbon nanotube web; forming a laminate by stacking the carbon nanotube web in a plural number so that the plurality of carbon nanotube single yarns are extended is in parallel; and twisting the laminate.
