【摘要】 首先介绍棉纤维与铜氨纤维的结构差异，并详细阐述一种快速制备铜氨纤维的方法。通过对实验各环节以及红外光谱的解析，拟揭示铜氨纤维制备中发生的剥皮反应、氧化降解及水解作用导致的纤维素聚合度下降，同时帮助师生理解诸如材料改性、氢键、配合物等相关知识。更多还原

【Abstract】 In this paper,the structural differences between cotton fiber and copper ammonia fiber are introduced,and a method for preparing copper ammonia fiber is described in detail.Through the analysis of each link of the experiment and infrared spectrum,it is intended to reveal the degradation of cellulose polymerization caused by peeling reaction,oxidative degradation and hydrolysis in the preparation of copper ammonia fiber,and help teachers and students understand the relevant knowledge such as material modification,hydrogen bonding and complex.更多还原
