摘要
通过聚乳酸(PLLA)、聚乙醇酸(PGA)的复合纺丝,获得一种新的皮芯复合纤维,并对纤维拉伸特性和微观结构进行探讨.结果表明:PGA和PLLA在熔融纺丝时没有发生酯交换反应,纤维的强度随牵伸倍数的增加而增大,结晶度和取向度都得到提高,纤维的机械性能可以达到纺丝要求.
A new core-sheath conjugate fiber was obtained through PLLA and PGA conjugate spinning, and the tensile properties and micro-structure were discussed. The results show that ester interchange reaction doesn't occur between PGA and PLLA of the fiber melt-spinning. The tensile strength of the conjugate fibers increases with increasing draw ratio, the crystallization and orientation improve greatly. The conjugate fiber mechanical properties can meet the requirement of spinning.
