纤维素的性能与其结构有密切关系,因而纤维素的结构问题是许多年来大家关心的问题。有关纤维素化学加工的各种生产实践中常常需要纤维素结构研究的理论启示。例如值得一提的,近十年来,粘胶纤维的强度几乎提高了一倍,疲劳强度提高了5—7倍,以及其他有关重要性能指标的提高,使粘胶纤维已成为近代轮胎工业中不可缺少的材料。早期曾经认为纤维的力学性能提高,特别是断裂强度提高主要与纤维素分子的聚合度有关。今天看来这样的理解是不全面
The properties of cellulose are closely related to its structure, and the structural problems of cellulose have been a matter of concern for many years. The theoretical implications for the study of cellulose structure are often required in various production practices related to cellulosic chemical processing. For example, it is worth mentioning that in the recent ten years, the strength of viscose fiber has almost doubled, the fatigue strength has been increased by 5-7 times, and other important performance indexes have been improved, so that viscose fiber has become a modern tire industry. Lack of material. Earlier it was thought that the mechanical properties of the fiber increase, especially the increase of the breaking strength mainly related to the degree of polymerization of cellulose molecules. It seems that such an understanding today is not comprehensive
