摘　　要：用无机活性炭与丙烯腈-偏氯乙烯共聚体共混,以二甲基甲酰胺(DMF)为溶剂纺制了腈氯纶吸附与阻燃纤维．文中研究了活性炭作为无机共混添加物在腈氯纶纺丝原液中的分散性和活性炭含量及纺丝工艺参数等对纤维机械性能的影响,并以此确定了最佳工艺参数．结果表明,适合纺丝的活性炭微粉平均粒径约为 0．8μm;且所添加的活性炭质量分数不应超过30％;纺丝最佳工艺参数为喷丝速度9．55 m／min,凝固浴温度6℃,凝固浴中DMF质量分数55％,拉伸浴温度70℃,牵伸速度3．33 m／min．By mixing activated carbon with AN-VDC copolymer and using DMF as the solvent of coagulation bath, the absorbable and flame retardant AN-VDC copolymer fibers is prepared. The dispersibility of activated carbon as inorganic adding mixture in AN-VDC copolymer spinning liquid, the influences of the content of activated carbon and the spining parameters on the mechnical properties of fibers are researched, then the optimum spinning pa- rameters are determined. The results show that the diameter of activated carbon particle suitable for spinning is about 0.8 μm, and the content of activated carbon shouldn＇t be beyond 30%, and the optimum spinning parameters are that the spinning rate is 9.55 m/min, the coagulation bath temperature is from 6 ℃ to 10 ℃ and the content of DMF in coagulation bath is 55%, the temperature＂ of drawing bath is 70 ℃, the drawing rate is 3.33
