## Abstract The zoneβdrawing method has been applied to prepare ultraβhigh modulus polyvinyl alcohol fibers. First, the suitable temperature for zoneβdrawing was decided. In the first zone drawing, when drawing temperature was as high as near melting point, the highest draw ratio and modulus were o
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
