Chitosan is partially or completely N-deacetylated derivative of chitin and is chemically composed of β‑(1, 4) linked 2‑amino‑2‑deoxy‑β‑d‑glucopyranose. Biocompatibility, non-toxicity, antifungal activity, water-binding capacity, bioactivity and antimicrobial properties make chitosan particularly attractive substitute for synthetic polymers in different application fields and notably in the textile industry. The presence of reactive amino and hydroxyl groups along the backbone conifer chitosan some interesting properties for use in textile dyeing and finishing. However, the main barrier to the use of chitosan is the lack of water solubility at neutral pH and poor durability on textile surfaces. To overcome this, chitosan has been chemically modified in several ways to obtain a wide range of important derivatives with a broad range of applications. This review is intended to provide a recent overview of chitosan and its derivatives and highlight their role in the development of antimicrobial textiles.
壳聚糖是几丁质的部分或完全 N-脱乙酰化衍生物，其化学组成是β-（1，4）连接的 2-氨基-2-脱氧-β-d-吡喃葡萄糖。壳聚糖具有生物相容性、无毒、抗真菌活性、保水能力、生物活性和抗菌性能，使其成为不同应用领域（特别是纺织工业）中合成聚合物的特别有吸引力的替代品。由于其骨架上存在反应性的氨基和羟基，壳聚糖具有一些在纺织染色和整理中使用的有趣特性。然而，壳聚糖使用的主要障碍是在中性 pH 值下缺乏水溶性和在纺织表面上的耐久性差。为了克服这一问题，壳聚糖已通过多种化学方法进行修饰，以获得具有广泛应用的一系列重要衍生物。本文旨在提供壳聚糖及其衍生物的最新概述，并强调它们在抗菌纺织品开发中的作用。
