摘　　要：讨论了气凝胶在聚酯中的应用情况,讨论添加不同比例的气凝胶对聚酯的影响情况,添加气凝胶的方式对能否进行缩聚反应非常重要,研究气凝胶-PET共聚酯聚合与纺丝工艺,当聚酯中气凝胶含量达到1%时,共聚酯切片外观及可纺性较好,纤维极限氧指数达到31.3%,阻燃性能较好。The application of aerogels in polyester is discussed.The influence of aerogels with different proportions on polyester is discussed.Aerogels are very important for polymerization.The aerogel-PET copolymerization and spinning process are studied.When the aerogel content in polyester reaches 1%,the appearance and spinnability of copolyester chips are better,and the limiting oxygen index of fibers reaches 31.3%,good flame retardancy.
