摘　　要：对采用NaSCN的一步法、二步法的湿纺工艺生产的腈纶的染色性能进行了研究和比较。染色饱和值、上染率中心值、染色吸附等温曲线和升温上染曲线测试结果表明,由于共聚体中第三单体含量的差异,二步法腈纶较一步法腈纶染色饱和值低、染色速率慢,最终上染率也较低。The dyeing properties of acrylic fibers produced with NaSCN one - step and two - step wet - spinning processes were studied and compared. Testing results of dyeing saturation value,central value of dye - uptake rate,dyeing adsorption isothermal curve and heating dyeing curve showed that comparing with one -step acrylic fibers, two - step acrylic fibers were low in dyeing saturation value, dyeing speed and final dye - uptake rate due to the difference in contents of the third monomers in copolymer.
