摘　　要：本研究对自制聚对苯二甲酸乙二醇酯(PET)沉析纤维进行筛分处理,并与PET短切纤维混抄成纸,探讨了沉析纤维的尺寸效应对PET纸结构、机械及电气性能的影响。结果表明,筛分目数为100、含量50%的PET沉析纤维成纸性能最好,PET纸匀度指数达94,抗张指数56.2 N·m/g,撕裂指数42.9 mN·m^(2)/g,层间结合强度79.4 N·m/g,耐压强度9.51 kV/mm。In this study,the self-made polyethylene terephthalate(PET)precipitated fiber was screened and mixed with PET chopped fiber to form paper.The effects of the precipitation fiber size on structure,mechanical and electrical properties of PET paper were discussed.The results showed that the PET precipitation fiber with 100 mesh and 50%content had the best performance,with a uniformity index of 94,a tensile index of 56.2 N·m/g,a tear index of 42.9 mN·m^(2)/g,an interlayer bonding strength of 79.4 N·m/g and a compressive strength of9.51 kV/mm.
