PET/纳米矿物粒子纤维的结构与性能

 将纳米矿物粒子和聚酯切片共混纺丝，经碱减量处理后制备了PET/纳米矿物粒子纤维．对纤维表面和横截面的SEM观察显示，纳米矿物粒子在纤维中的颗粒比较小，由表及里都分散的比较均匀，纤维存在明显的微孔结构．X射线衍射分析表明，添加纳米矿物粒子后，聚酯纤维的晶形没有改变，其晶粒尺寸增加，而结晶度和取向度降低．性能分析表明，相比普通聚酯纤维，其断裂强度有所降低，但断裂伸长率和断裂功增加，特别是导湿性能改善最为显著，而质量比电阻明显降低．

Structure and properties of PET fibers with nano-mineral particles

PET fibers with nano-mineral particles were prepared by mixing nano-mineral particles with PET pellets and subsequent alkali weight reduction.SEM observation for the surface and cross section of the fibers showed that the mineral particles with a small size dispersed from the surface to the inner of the fibers,which had apparent microcellular structure.With the addition of nano-mineral particles,there was no change for the crystalline allomorphs of the PET fibers,but its crystallite size increased,moreover ...
