摘　　要：以丙烯腈(AN)、醋酸乙烯酯(VAc)、碱性第三单体(TAM)为单体共聚合制得聚合物,并将聚合物浆化溶解,试纺出酸性可染聚丙烯腈纤维,用酸性染料对其进行染色,测得平均上染率为90%。对制得的纤维进行DSC分析和SEM分析,发现纤维无序结构的增加以及TAM的亲水性有利于该纤维与酸性染料作用,提高了上染率。The copolymer made from AN, VAc and TAM can be spun to polyacryonitrile fibers which can be dyed with acid dyes, and the dye-uptake of the fiber can be up to 90%. Through DSC and SEM analysis the results reveal that the increase of disorder structure and hydrophile of TAM in this kind of fiber are very useful for its function with acid dyes. Furthermore, the dye-uptake improves.
