摘　　要：纤维素是自然界中最丰富的可再生资源,具有量大价廉、可再生、再生周期短、可生物降解和环境友好等诸多优点。但由于其结构特点,使天然纤维素的应用受到很大的限制。而将其溶解后再生,可拓展纤维素的应用前景。针对应用目的不同,对再生纤维素的结晶结构要求也不同。本文主要综述了溶解体系、溶解时间、溶解温度、溶解浓度、沉淀剂类型、沉淀方式、干燥方式等再生条件对再生的纤维素结晶度的影响。Cellulose is the most abundant renewable resources in nature,which shows substantial advantages including low costsources,short regeneration time,biodegradable and environment friendly. But its application area is largely limited because of itsmolecular structure. The potential availability of cellulose can be expanded by dissolution and regeneration. The crystal structure ofthe regenerated cellulose varies for different application areas. This article mainly reviewed that the regenerated cellulose crystallinitycould be affected by different regeneration conditions such as dissolution system,dissolution time,dissolution temperature,dissolutionconcentration,precipitation agent,precipitation method,drying method,and so on.
