摘　　要：采用原位聚合的工艺,制备出含微量稀土元素的镁电气石超细粉体/聚酯复合材料,运用涤锦复合高速纺丝POY-DTY二步法技术,生产出涤锦(70/30)负离子超细纤维的DTY长丝,对工艺参数与纤维力学性能之间的关系进行探讨,确定了最佳参数,测试了纤维的负离子发生率。结果表明,由于负离子粉体的加入,导致切片熔点降低,宜采用较低的纺丝温度和纺速,侧吹风风速控制在0.5 m/s为宜,负离子纤维的强力与断裂伸长率比普通聚酯纤维有所下降,电气石质量分数为2.5%的超细纤维负离子释放达到800个/cm3,是公园环境下负离子水平的4倍。The magnesium tourmaline superfine powder/polyester composite polymer containing trace rare earth elements was produced by in-situ polymerization.The DTY anionic polyester/polyamide（70/30） microfibers were produced with POY-DTY two-step technology.The relationship between the technologic parameters and mechanical performance was discussed,the optimal technology was determined,and the anionic release rate of the fibers was tested.The results showed that polyester′s melting point was reduced due to the addition of anionic powders,and lower spinning temperature and speed should be adopted with the cross air blasting controlled at 0.5 m/s.The strength and breaking elongation of the anionic fibers were declined compared with those of the ordinary polyester fibers.The anionic release of the anionic microfibers with mass fraction of tourmaline 2.5% was up to 800 per cubic meter,that was 4 times as much as the anionic concentration in the park.
