| 摘 要： | 以聚乳酸切片为原料，通过熔融纺丝一热板拉伸二步法制得聚乳酸纤维，研究了纺丝温度、拉伸温度、拉伸倍数对聚乳酸纤维性能的影响．实验结果表明，聚乳酸有良好的成纤性；当拉伸倍率为4倍时，聚乳酸纤维的性能最好，即纤维的结晶度、取向度、断裂强度均表现出最佳值． |
| 关 键 词： | 聚乳酸 熔融纺丝 拉伸 |

| Abstract: | PLA filament was made from PLA chips by melt-spinning and heat-plate drawing. The effects of temperature and drawing ratio on filament performance were investigated. The results show that the PLA has good fiber-forming behavior. The filament is of best behavior at a drawing ratio of 4, i. e, the break strength, crystallization and orientation of the filament reach the best. |
| Keywords: | PLA melt spinning drawing |
