The morphology of polyethylene spherulite in two deformation steps before and after annealing was investigated under the polarizing microscope. It was found that the first deformation step is reversible while the second one is irreversible. Furthermore
it is revealed that the fracture of fibre results from the longitudinal sliding displacement of fibrils or microfibrils.
