Abstract

A yarn producing apparatus 1 is an apparatus for producing carbon nanotube (CNT) yarn Y by aggregating CNT fibers F and includes a substrate support 10 configured to support a CNT forming substrate S, a winding unit 7 configured to continuously draw the CNT fibers F, a yarn producing unit 4 configured to aggregate the CNT fibers F, a status monitor 6 configured to monitor a state of the CNT yarn Y, and a supply state changing mechanism 20 configured to change a supply state of the CNT fibers F, based on a result of monitoring by the status monitor 6.

Description

technical field [0001] The invention relates to a yarn manufacturing device for manufacturing carbon nanotube yarns from carbon nanotube fiber groups. Background technique [0002] As a yarn manufacturing apparatus as described above, there is known a device that includes a drawing unit that continuously draws out carbon nanotube fibers from a carbon nanotube forming substrate, and that performs a process on the carbon nanotube fibers drawn out by the drawing unit. Yarn manufacturing in a yarn manufacturing section that manufactures yarn by twisting (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2010-116632 [0004] In such a yarn manufacturing apparatus, for example, depending on the quality of the carbon nanotube forming substrate or the like, the pulling performance of the carbon nanotube fiber group from the carbon nanotube forming substrate may vary. When the drawing performance is lowered, a predetermined amount o...
