Abstract: <正>The morphology,mechanical and dynamic mechanicalproperties and shielding efficiency of the novel X-rayshielding fibers were analysed.The results show that thestructure defects which exist in as-spun fibers are obvi-ously reduced in the drawn fibers.The tensile strengthand the elongation at break of drawn fibers decrease withthe increase of the shielding agent content and the tensilestrength increases with the increase of the drawn-foldof the fibers.On the E’-T curves,as the shielding agentcontent increases,there is first an increase,then a de-crease in the E’value above 60% of the shielding agent.Their thermal properties also change evidently.Theshielding efficiency of their nonwoven fabrics is obvious.
