| 摘 要： | This paper deals with the fracture feature of three kinds of polyester fibers with differentstructures under different tensile conditions.We studied fracture initiation,crack propagationand ultimate fracture characteristics under tension of polyester fibers.The fracture features ofpolyester fibers are related with fiber structure and tensile condition.Crack is initiated in fibersurface.It propagates from outside to inside and eventually causes rupture of the fiber.In addi-tion,it is stated also that the analysis on tensile fracture feature of fibers might be confirmed bydynamic testing technique of scanning electron microscopy.
