摘　　要：通过β射线辐照涤纶纤维,研究不同辐射吸收剂量的涤纶纤维的表面形态、力学性能和抗紫外性能。结果表明,经β射线辐照后的涤纶纤维表面的粗糙度增加,比表面积增加;β射线辐照增强了涤纶纤维织物的抗紫外线防护能力,且随着辐照剂量的增加,抗紫外线防护能力增加;β射线辐照使涤纶纤维的断裂强力下降,且当辐照吸收剂量高于300 KGy后,断裂强力下降明显。The morphology, mechanical property, and uhraviolet resistance of the polyester fiber absorbed different β radiation dose are evaluated. It is found that the surface roughness and specific surface area of the polyester fiber are increased after modified by β ray. The β ray modification enhanced the ultraviolet： resistance of the polyester fabric, and the ultraviolet resistance increases as the absorbed radiation dose increases. The breaking strength of the polyester fiber decreases after β ray modification, and the breaking strength decreases distinctly when the absorbed radiation dose is above 300KGy.
