A CNT spun yarn is produced by twisting the CNT web with a spindle that moves backward with respect to the CNT forest and pulling it out. The number of twists and the twist angle are controlled by adjusting the spindle rotation speed and pulling speed. Typical twisting parameters are a rotation speed of 32,000 min-1 and a drawing speed of 120 mm\/s. In this case, when spinning a CNT web with a width of 5 mm, the yarn diameter is about 20 \u03bcm and the twist angle is about 25\u00b0. The surface of CNT twisted yarn has a morphology similar to that of general twisted yarn.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/cnt.eng.shizuoka.ac.jp\/wp-content\/uploads\/2019\/02\/CNT\u30dc\u30d3\u30f3.png\" alt=\"\" class=\"wp-image-503\" width=\"347\" height=\"348\"\/><\/figure><\/div>\n\n\n\n<figure class=\"wp-block-video aligncenter\"><video height=\"480\" style=\"aspect-ratio: 720 \/ 480;\" width=\"720\" controls src=\"https:\/\/cnt.eng.shizuoka.ac.jp\/wp-content\/uploads\/2019\/02\/02_720x480.mp4\"><\/video><figcaption>Fabrication of CNT yarn<\/figcaption><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\">Publication<\/h4>\n\n\n\n<p><strong>Study on the mechanical and electrical properties of twisted CNT yarns fabricated from CNTs with various diameters<\/strong><br>Yoku Inoue, Kohei Hayashi, Motoyuki Karita, Takayuki Nakano, Yoshinobu Shimamura, Keiichi Shirasu, Go Yamamoto, Toshiyuki Hashida<br>Carbon\u00a0<strong>176<\/strong>, 400-410 (2021).<br><a rel=\"noreferrer noopener\" href=\"https:\/\/doi.org\/10.1016\/j.carbon.2021.01.139\" target=\"_blank\">DOI: 10.1016\/j.carbon.2021.01.139<\/a><br><br><strong>Fabrication and mechanical properties of carbon nanotube yarns spun from ultra-long multi-walled carbon nanotube arrays<\/strong><br>Adrian Ghemes, Yoshitaka Minami, Junichi Muramatsu, Morihiro Okada, Hidenori Mimura, Yoku Inoue<br>Carbon <strong>50<\/strong>, 4579-4587 (2012).<br><a rel=\"noreferrer noopener\" href=\"http:\/\/dx.doi.org\/10.1016\/j.carbon.2012.05.043\" target=\"_blank\">DOI: 10.1016\/j.carbon.2012.05.043<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>We fabricate CNT yarns from the CNT web.
