摘　　要：将采用原位聚合法自制的核-壳型碳微球(CMSs)/聚对苯二甲酸乙二醇酯(PET)微胶囊(PCMSs)作为阻燃剂,采用熔融纺丝法制备阻燃PCMSs/PET功能纤维。通过扫描电镜、声速仪、强伸仪、极限氧指数仪等测试设备对添加不同质量分数的阻燃剂的阻燃功能纤维的结构及性能进行测试和表征。结果表明:当阻燃剂PCMSs的质量分数为0.6%时,PCMSs在PET纤维基体中的分散性和相容性良好,此时纤维表面较为光滑,同时具有优良的吸湿性能和阻燃性能,但其力学性能稍低于PCMSs质量分数为0.2%时的PCMSs/PET纤维。The core-shell carbon microspheres(CMSs)/polyethylene terephthalate(PET)capsule(PCMSs)by in situ polymerization was selected as flame retardant.The flame-retardant PCMSs/PET functional fiber was prepared by melt spinning method.The structure and properties of PET fiber with different mass fractions of flame retardant were characterized by SEM,sound velocimeter,tensile tester and limit oxygen index apparatus.The results show that PCMSs has a good compatibility and dispersion within PET matrix,and the excellent moisture absorption and flame retardant properties of functional PET fiber with smooth surface is obtained when the mass fraction of PCMSs is0.6%,but the mechanical property of PCMSs/PET fiber with 0.6% PCMSs is a little lower than the PCMSs/PET fiber with 0.2% PCMSs.
