摘要

Filament multiple wound yarn ones which are produced multiple wound yarn method of the filament with and that are disclosed. Because in detail, the solution thread being able to point to the filament of the plural books with uniform solution thread tension, the multiple wound yarn after doing, to retract it is possible the multiple wound yarn method of the filament which relates to this invention in non twist state, at the time of the solution thread for rear processing, portion of the filament which the multiple wound yarn it does it can prevent the phenomenon which hangs with tension deviation extending effectively. As for any filament multiple wound yarn things of this invention the filament the multiple wound yarn is done in non twist state, per unit length of filament multiple wound yarn ones weight standard deviation of the filament which forms this is 0.0001 - 0.01. This invention when producing the optical cable, especially is useful in the multiple wound yarn of all the aromatic polyamide filaments which the optical fiber the cover ring are done.
