摘要(Abstract):
采用DDV-II型粘弹谱仪对Lyocell纤维的动态力学性能进行了研究。实验结果表明:与粘胶纤维不同,Lyocell纤维的力学损耗正切─温度曲线有两个明显的力学吸收峰,包含两种不同的吸收机理,并且纺丝速度对Lyocell纤维的动态力学性能有一定的影响。
The dynam ic m echanicalproperty ofLyocellfiberw as studied by the dynam ic viscoelastic m ethod. The result showed that the dynamic loss tan!- T curves of Lyocell fiber had two peaks and included two types of viscoelastic absorption mechanism. This was different from the viscose fiber apparently.The spinning speed had some influence on the dynamic mechanical property.
