Abstract (en)
A periodic unevenness detecting method executed in a textile processing system (100) in which a first fiber bundle (S) that is produced by an upstream process machine (130) is at least drafted by a downstream process machine (150) to produce a second fiber bundle (Y), the periodic unevenness detecting method including a first acquisition step of acquiring first information concerning the upstream process machine (130), a thickness unevenness detecting step of detecting thickness unevenness information concerning periodic unevenness of thickness in the second fiber bundle (Y), and a periodic unevenness identifying step of identifying, based on the first information, the thickness unevenness information, and a total drafting ratio in the downstream process machine, periodic unevenness occurring in the second fiber bundle (Y) due to the upstream process machine (130).
