To prepare high-modulus fibers, the vibrating hot-drawing and zone-annealing methods have been applied to nylon 6. The vibrating hot drawing was repeated two times, increasing the applied tension; further, the zone annealing was superposed on the vibrating hot-drawn fibers. The superstructure and me
## Abstract A laserβheating zoneβdrawing and zoneβannealing method using a continuousβwave carbon dioxide laser was applied to poly(ethylene terephthalate) (PET) fiber to improve its mechanical properties. The asβspun fiber was zoneβdrawn under a applied tension (Ο~__a__~) of 4.44 MPa at a laser po
