Abstract:
In recent years, with the development of natural polysaccharide in the field of material, cellulose and chitosan have attracted wide attention. Because of its excellent biocompatibility, biodegradability and antibacterial properties, chitosan has attracted attention of many researchers.Great progress has been made in the medical, food, environmental engineering and many other fields. This paper starts from the solution properties of chitosan, introducing the effect of deacetylation degree, molecular weight, temperature and other factors on chitosan solution behavior, especiallywhenusing acetic acidandionic liquid.Also, we summarize the wet spinning of chitosan, as well as the methods to improve the performance of fiber and the possibility of filament realizing.Finally, the future development of chitosan and its fiber products are prospected.
