摘　　要：利用动态粘弹谱仪考察和分析了新型再生纤维素纤维的动态粘弹性能。结果表明，在-150℃－35O℃温度范围内，再生纤维素发生了复杂的松弛和转变，这些松弛和转变表明再生纤维素的结构非常复杂，而产生这一复杂性的根本原因是纤维素中大量的复杂的氢键作用及其运动。从帕弹性角度对氢键进行了讨论，首次提出了红键破碎区，同时首次发现了纤维素在更低温度下的y松弛。The dynamic viscoelastieity of a novel regener-ated cellulose fiber has been investigated. The results show that there were several relaxations in the dynamic viscoelastic spectra of The regenerated cellulose, indicating a complexity in the structure of the regenerated cellul0se. The complexity is mainly due to the intra - and inter - molecular hydrogen bonding and the motion and rearrangement of the hydrogen bonds. From the view point of dynamic viscoelasticity, the hydrogen bonding and rearrangement have been discussed in this paper. For the first time,the mechanism of hydrogen bond breaking region has been put fOrward. In addition, the Y relaxati0n has been discovered for the first time.
