序态和取向是纤维素纤维超分子结构的两个重要特性。Sisson认为,侧序度和取向度是纤维素纤维物理机械性能的决定因素。Howsmon的实验表明,在取向度相同的情况下,粘胶纤维的断裂强度、延伸度和韧性随侧序度的降低而增大。Навикова得到了相似的结果,并且证明:随着侧序度的降低,纤维的疲劳性能和吸水性相应地提 The order and orientation are two important properties of cellulose fiber supramolecular structure. Sisson believes that the degree of orientation and degree of orientation are the determinants of the physical and mechanical properties of cellulose fibers. Howsmon’s experiments show that the breaking strength, elongation and toughness of viscose fibers increase with decreasing degree of orientation under the same degree of orientation. Навикова obtained similar results and demonstrated that as the degree of lateral order decreases, the fatigue properties and water absorption of the fibers are correspondingly raised
