Abstract
A production method of a carbon nanotube yarn includes the steps of: (1) obtaining a web 40 including a large number of carbon nanotubes 36; (2) bringing a slider 24a into contact with the carbon nanotubes 36; and (3) moving the slider 24a in a direction to bundle the carbon nanotubes 36, the direction being inclined with respect to a direction in which the web 40 extends.
Claims8
A production method of a carbon nanotube yarn, the production method comprising the steps of:
- (1) obtaining a web including a large number of carbon nanotubes;
- (2) bringing a first slider and a second slider which is located downstream of the first slider into contact with the carbon nanotubes;
- and
- (3) reciprocating the first slider in a direction inclined with respect to a direction in which the web extends, and at the same time reciprocating the second slider in a direction opposite to a movement direction of the first slider, to bundle the carbon nanotubes.
1 more element
A production apparatus for a carbon nanotube yarn, the production apparatus comprising:
- a first slider that contacts a web including a large number of carbon nanotubes or a bundle obtained from the web;
- a second slider that is located downstream of the first slider and contacts the web or the bundle;
- and
- a drive mechanism that reciprocates the first slider in a direction inclined with respect to a direction in which the web extends and at the same time reciprocates the second slider in a direction opposite to a movement direction of the first slider.
1 more element
A strand comprising a large number of carbon nanotubes, wherein
- the strand includes:
- a right-twisted portion in which all the carbon nanotubes contained therein are twisted in an S direction;
- and a left-twisted portion in which all the carbon nanotubes contained therein are twisted in a Z direction.
