In allusion to some types of the functional fibre s performances and characters the paper mainly has this fibres microstructure scanned by electron microscrope . in addition we also discuss their differences of microstructure eroded by the plasm . meanwhile by performing mechanics analysis we get theoretical analysis of their space - conglomerating structure . finally we perform analysis of the ultraviolet radiation and analysis of the caloricr weightlessness . as a result these types of fibre not only keep their own fine traits , but also own good conglomerating structure , crystal limit , calorifics performance and mechanics performance . compared with the ordinary fiber , the neatness of high - contracted polyester fiber increases and it s diameter also increases . there are bubbles in the burning - resisting viscose fiber and it has smooth vertical structure 对应子高收缩的涤纶纤维的平整度有所提高，有较普通纤维变粗的趋势；在难燃粘胶纤维里面有气泡，其具有较明显的光滑平整纵向结构；涤纶系列棉纤维，在其耐刻蚀方面是比较强的，仅有均匀的小部分刻蚀现象；抗菌卫生级粘胶纤维的刻蚀效果是较差的：难燃的粘胶纤维，刻蚀的效果最好；而抗紫外粘胶纤维刻蚀的效果略有逊色。
