摘　　要：采用射频干燥技术对腈纶干燥工艺进行了试验,探讨了射频作用时间、电极电压、丝束堆积密度和丝束含水率对腈纶纤维回潮率的影响,通过正交试验研究了这些因素的影响程度。研究结果表明,射频作用时间和电极电压对回潮率影响最大,随着作用时间的缩短,回潮率具有明显的上升趋势;随着电极电压的下降,在相同作用时间下,回潮率呈上升趋势。The presented research employed radio frequency drying technology for the drying process of acrylic fibers manufacture. The acting time, electrode voltage, packing density, imported water content fluctuations and other related factors were discussed to analyze their effects on the moisture regain of acrylic fibers. The obtained results showed that the acting time and electrode voltage were the most important affecting factors for the moisture regain of acrylic fibers. With the decrease of action time, the moisture regain had an obvious upward trend. In the same acting time, the moisture regain rose with the decline of electrode voltage.
