摘要/Abstract

摘要：

为增强增韧聚乳酸纤维，采用聚酰胺（PA）与聚乳酸（PLA）制备了PLA/PA 共混纤维，并对其热学性能、结晶、热稳定性、PA 的分散性以及PLA/PA共混纤维的力学性能进行了研究。研究结果表明：PA的加入对PLA 的玻璃化转变温度及熔融温度没有显著影响，但改善了PLA的结晶行为，结晶度提高了51.6%；PLA 热稳定性随着PA 含量的增加而提高；PA在PLA 中分散均匀；随着牵伸倍数的增加，PLA/PA 共混纤维的取向度提高，力学性能得到改善，当牵伸倍数从1.5增加到3.0 时，取向度提高了30.88%，同时纤维的断裂强度提高了48.58%；当ＰＡ质量分数为1%和20%时，PA/PLA共混纤维的断裂强度分别提高了8.6%和25%，断裂伸长率分别提高了10.9%和55.9%。

Abstract:

In order to reinforce and toughen polylactic acid (PLA) fiber, polyamide (PA) was blended with PLA, and then spun. The thermal property, crystallization, heat stability, dispersibility of PA and mechanical property of PLA/PA fiber were studied. The results show that the addition of PA has no significance 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 551.6%. The heat stability of PLA was improved with the increasing of the content of PA, and the dispersibility of PA is very uniform in PLA. With the increasing of draft ratio, the orientation degree and mechanical property of PLA/PA fiber are enhanced. When the draft ratio increased from 1.5 to 3.0, the orientation degree and breaking strength of PLA/PA fiber enhanced 30.88% and 48.58%, respectively. When the content of PA is 1% and 20%, the breaking strength of PLA/PA fiber increased 8.6% and 25%, and elongation at break of PLA/PA increases by 10.9% and 55.9%, respectively.
