【摘要】 研究无机粒子（代号为ＥＭ）共混收性聚丙烯（ＰＰ）纤维的力学性能、结晶性能和电磁屏蔽性能，讨论无机粒子含量与纤维各项性能之间的关系。认为无机粒子含量为５％时，纤维的综合性能最好。更多还原

【Abstract】 In the paper, we study the system of inorganic particle (named as EM) blended with polypropylene fibers. We discuss the relationship between the inorganic particle content and the mechanical property, crystallinity and Electromagnetic Shielding (EMS) effect. The modified PP fiber shows good EMS ability, and the mechanism of the fiber is testified to be of reflection type. The modified fiber exhibits a good property when the content of EM is 5%.更多还原
