摘要
为深入研究壳聚糖(CS)在抗菌纺织品上的应用,对CS的抗菌机制及其抗菌纺织品开发现状进行综述。介绍了分子质量、脱乙酰度、溶液浓度、pH值、溶剂种类、衍生化等因素与抗菌性的关系。结合实际应用认为,CS要发挥优良的抗菌性,应具有高脱乙酰度,中等分子质量,以乙酸作为溶剂,pH值略高于4即可,同时其质量浓度在2.5 g/L以上,还可通过衍生化反应进一步提高其抗菌性。分析CS抗菌纺织品开发现状得知,目前主要通过对传统织物固着CS后整理和开发CS纤维制品这2种方式实现纺织品抗菌,前者抗菌性会随产品洗涤次数增加而逐渐降低,而后者将是较好的解决办法,但还有待进一步研究。
A review of the antibacterial mechanism of chitosan （CS） and the current status of the development of antimicrobial textile was conducted for the purpose of investigating the application of CS to textiles. The effects of molecular weight （MW） , degree of deacetylation （DD） , solution concentration, pH value, types of solvents and derivatives of CS on its antibacterial activity were discussed. It was found by practice that CS with medium MW and high DD, which dissolved in acetic acid at a concentration of over 2.5 g/L with pH value more than 4, possesses excellent antibacterial activity, which can be further enhanced by the derivation of CS. It was shown through analysis that at present there are two ways to produce antimicrobial textile with CS, i. e. , fixing CS to the traditional textile and producing CS fiber products. For the former, the antibacterial activity reduces gradually with washing times. For the latter, it has permanent effect. However, further research is needed for products with good antimicrobial performance.
