摘要
测试分析了竹浆纤维、莱赛尔纤维、莫代尔纤维和黏胶纤维的结构与性能。结果表明,竹浆纤维和黏胶纤维纵向有明显的沟槽,莫代尔纤维纵向沟槽较少,莱赛尔纤维纵向表面平滑无沟槽;4种纤维显示出纤维素Ⅱ晶型特征,与莱赛尔纤维相比,竹浆纤维、莫代尔纤维与黏胶纤维的结晶度较低;纤维红外谱图显示4种纤维的化学结构和基团大体相同;干态条件下竹浆纤维和黏胶纤维的断裂强度小于莱赛尔纤维和莫代尔纤维,湿态条件下4种纤维的断裂强度均有下降,断裂伸长率均有增加。
The structure and properties of bamboo pulp fiber, lyocell fiber, modal fiber and rayon fiber were tested. The results showed that bamboo pulp fibers and viscose fibers had obvious grooves in the longitudinal direction, modal fibers had less grooves, and lyocell fibers had smooth longitudinal surface without grooves. The four fibers showed the cellulose II crystal characteristics. Compared with lyocell fiber, bamboo pulp fiber, modal fiber and viscose fiber had lower crystallinity. The infrared spectra of fiber showed that the chemical structures and groups of the four fibers were same substantially. Under dry conditions, the breaking strength of bamboo pulp fiber and viscose fiber was lower than that of lyocell fiber and modal fiber. Under wet conditions, the breaking strength of the four fibers decreased and the elongation at break increased.
