蓄光型稀土长余辉聚酯长丝的性能研究

Study on the properties of light-storing rare earth long afterglow PET filament

研究测试了蓄光型稀土长余辉聚酯长丝的发光性能、断裂强力、断裂伸长和热收缩性能与稀土长余辉化合物添加量的关系。结果表明:随着稀土长余辉化合物添加量的增加,余辉性能显著提高,但断裂强力明显降低,断裂伸长提高,长丝的抱合力和可织造性能也降低。

The relations of the luminescent, breaking strength, breaking elongation and thermal shrinkage properties of light-storing rare earth long afterglow PET filament against the adding quantity of rare earth long afterglow compounds are tested. The result shows that the property of afterglow will be improved significantly, but its breaking strength will decrease markedly and the breaking elongation will increase as well as the filament cohesion and knittability will diminish with the increase of rare earth long afterglow compounds.
