A yarn production process for enabling a yarn formed by filling the interior of a tubular member configured by knitting or braiding a fibrous material with expanded graphite as a base material, to be produced in a state of a high productivity in order to enable the yarn to be actually used in an economical manner is realized and provided. In order to realize this, in a process of producing a yarn formed by filling the interior of a tubular member 3 configured by knitting or braiding a fibrous material 2 with expanded graphite, the process has: a fine cutting step s of successively cutting an expanded graphite sheet 9 which is continuously supplied in a state where the sheet has a predetermined width, to a small width along the width direction of the sheet; and a supplying and filling step k of guiding and supplying a strip-like expanded graphite material 4 which is produced by the fine cutting step s, into the tubular member 3 to be filled into the tubular member. |
