## 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

The kinetics of the "cold crystallization" of poly(ethylene terephthalate) (PET) pre-orientated yarns are investigated both in isothermal and in non-isothermal dynamic conditions. The amorphous-crystalline, solid-solid transformation is analyzed in terms of the Avrami equation and of Ozawa's theory.

High-speed melt spinning of poly(ethylene terephthalate) was performed using a spinning nozzle with an inserted metallic wire of various lengths (0, 8, 30, and 45 mm). The molecular orientation of as-spun fibers increased with the increase in the wire length at all the take-up velocities examined. A
