High tensile strength ultra high molecular weight polyethylene (UHMWPE) fibers were prepared via the dry spinning method. Raw material was UHMWPE resin with 6 million viscosity-average molecular weight (Mv). Changes of morphology, mechanical properties, thermal properties and crystallization process of the fibers in the ultra-hot drawing process were studied by scanning electron microscopy (SEM), tensile tester, differential scanning calorimetry (DSC), and wide-angle X-ray diffraction (WAXD). Results show that there was a maximum value of fracture force at a draw ratio of 40 and excessive draw ratio destroyed crystal structures in fibers and led to a decrease in the fracture force value. A shoulder peak appeared in DSC curves of ultra-drawing samples and its peak value maintained at 154°C in different samples. In addition, three peaks can be observed in all WAXD patterns of drawing samples. The mechanism of microstructural changes during the hot drawing process was elucidated.
