摘　　要：近年来,随着天然大分子多糖在材料领域的不断研究应用,纤维素、壳聚糖等逐渐引起了人们的广泛关注。由于其自身优异的生物相容性、抗菌性以及可降解性,壳聚糖吸引了众多研究者的高度重视,在医疗、食品、环境工程等领域的研究和应用均取得了可观的进展。首先从壳聚糖的溶液性质研究出发,分别介绍了脱乙酰度、温度、分子量等因素对壳聚糖溶液的溶解行为的影响,重点介绍了醋酸和离子液体体系下的溶液性质,其次对壳聚糖的湿法纺丝研究进行了综述,同时对纤维性能的提高方法以及长丝的实现可能性进行了总结,最后对壳聚糖及其纤维制品的未来发展前景进行了展望。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 influence of deacetylation degree, molecular weight, temperature and other factors on chitosan solution behavior respectively, focusing on the introduction of chitosan dissolution using acetic acidandionic liquid, summarizing 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.
