【摘要】 通过X射线衍射、光学显微镜和扫描电子显微镜等方法研究了原液着色腈纶的结晶、取向及形态结构,并对原液着色腈纶纤维的物理、机械性能,热稳定性以及动态力学性能进行了研究,结果说明原液着色后的腈纶纤维的结晶度和取向度略有下降,但其本身的晶体结构及宏观形态结构没有发生显著变化;同时原液着色不会使PAN纤维的物理、力学性能明显劣化,其中的部分性能还会得到明显改善,但对纤维的热性能及动态热力学性能有不同程度的影响。所得结论对于原液着色腈纶纤维产品的开发及生产具有一定的指导意义。更多还原

【Abstract】 By the means of X-ray diffraction analysis,optical microscopy and scanning electron microscope,Its crystalline structure,orientation structure and morphology structure of the dope-dyed PAN fibers were investigated,the results show that the crystallinity and orientation of the dope-dyed acrylic fiber declined slightly,but its own crystal structure and morphology doesn’t significantly change,While the addition of pigment doesn’t make the PAN fibers degradation of physical and mechanical performances,even some performance is improved obviously,but the thermal properties and the dynamic performance of the fiber are influenced in different level Conclusion to the development and production of the acrylic fiber products has certain directive significance.更多还原
