| 摘 要： | 对复合PET/EVOH吸湿纤维进行纺丝实验,得到最佳的纺丝工艺参数。通过调整复合PET/EVOH吸湿纤维的皮层和芯层含量,可得到不同皮芯比的复合纤维。对得到的复合纤维进行力学性能和吸湿性能测试后发现:增加皮层PET的含量会使复合纤维的强度提高,纤维的可纺性变好;芯层EVOH含量的提高使复合纤维的吸湿性能得到改善;当皮芯比为5∶5时,复合PET/EVOH吸湿纤维的强度为2.53 cN/dtex,实际回潮率为1.6%,其可纺性及综合性能较好,可满足实际生产加工要求。

| Abstract: | PET/EVOH sheath-core fiber was prepared and the optimal spinning parameters were obtained.The PET/EVOH sheath-core fibers with various sheath-core ratios were prepared by changing the content of the PET and EVOH.After testing the mechanical properties and hygroscopicity of this fiber,it was found that increasing the content of PET would increase the tensile strength of the fiber and make the spinnability better;on the other hand,increasing the content of EVOH would increase the hygroscopicity of the fiber.When the sheath-core ratio was 5∶5,the tensile strength of the PET/EVOH fiber was 2.53 cN/dtex and the actual moisture absorption ration was 1.6%,which would provide the good spinnability and the general properties to meet the process demand. |
