摘要:

近年來，隨著天然大分子多糖在材料領域的不斷發展，纖維素、殼聚糖等逐漸引起了人們的廣泛關注。由于自身優異的生物相容性、抗菌性以及可降解性，殼聚糖吸引了眾多研究者的目光，在醫療、食品、環境工程等領域均取得了一定的研究進展。本文首先從殼聚糖的溶液性質研究出發，分別介紹了脫乙酰度、溫度、分子量等因素對殼聚糖溶液的溶解行為的影響，重點介紹了醋酸和離子液體體系下的溶液性質，其次對殼聚糖的濕法紡絲研究進行了概述，同時對纖維性能的提高方法以及長絲的實現可能性進行了總結，最后對殼聚糖及其纖維制品的未來發展前景進行了展望。

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.
