摘要/Abstract

摘要：

为提高聚乳酸(PLA)纤维的力学性能,采用聚丙烯(PP)与聚乳酸(PLA)通过熔融纺丝制备PLA/PP纤维,并借助差示扫描热量仪、热重分析仪、万能材料测试仪、纤维双折射仪对其热学性能、热稳定性、拉伸性能和纤维取向度进行表征。结果表明:PP的引入对PLA的玻璃化转变温度和熔融温度没有显著影响,但促进了PLA的结晶,结晶度提高了585.9%;随着PP质量分数的增加,PLA的热稳定性降低(特别是在初始分解阶段),但其残炭率提高,同时PLA/PP共混纤维的取向度提高,力学性能得到改善;当PP质量分数为20%时,PLA/PP共混纤维的取向度、断裂强度和断裂伸长率分别提高了55.6%,98.2%和44.4%。

Abstract:

In order to enhance the mechanical properties of polylactic acid (PLA) fiber, polypropylene(PP) was melt blended with PLA, then PLA/PP blend fiber was prepared by melt spinning. The thermal property, heat stability, tensile property and orientation degree of the PLA/PP fiber were tested using differential scanning calorimeter, thermal gravimetric analyzer, universal testing machine, fiber birefringence meter, respectively. The results show that the addition of PP has no significant effect on the glass transition temperature and melting temperature of PLA, but the crystallization behavior of PLA is improved, and the degree of crystallinity enhances by 585.9%. With the increasing of PP content, the heat stability of PLA is decreased, especially the initial decomposition temperature is decreased obviously, but the carbon yield is increased. Meanwhile , the degree of orientation and mechanical properties of the PLA/PP fiber are enhanced. When the PP mass fraction is 20%, the orientation degree, breaking strength and elongation at break of the PLA/PP fiber increase 55.6%, 98.2% and 44.4%, respectively.
