The high-speed melt spinning of poly(ethylene 2,6-naphthalene dicarboxylate ) ( PEN ) was performed up to the take-up velocity of the ultra-high-speed region, 9 km/min. From the investigations of the structure and physical properties of the asspun fibers, the high-speed spinning of PEN was divided i
## Abstract In recent years the spinning speeds of poly(ethylene terephthalate) (PET) fiber have increased to the point that significant structural development is being observed in the spun yarn. At even higher speeds significant crystallization has been obtained. Data characterizing these yarns wi
