Carboxymethyl chitosan (CMCTS) and silver nanoparticles (Ag NPs) were successfully linked onto a cotton fabric surface through a simple mist modification process. The CMCTS binder was covalently linked to the cotton fabric via esterification and the Ag NPs were tightly adhered to the fiber surface by coordination bonds with the amine groups of CMCTS. As a result, the coating of Ag NPs on the cotton fabric showed excellent antibacterial properties and laundering durability. After 50 consecutive laundering cycles, the bacterial reduction rates (BR) against both S. aureus and E. coli remained over 95%. It has potential applications in a wide variety of fields such as sportswear, socks, and medical textile.
羧甲基壳聚糖（CMCTS）和银纳米粒子（Ag NPs）通过简单的雾化改性工艺成功地连接到棉织物表面。CMCTS 粘合剂通过酯化共价连接到棉织物上，Ag NPs 通过与 CMCTS 的胺基形成配位键紧密附着在纤维表面。结果，Ag NPs 在棉织物上的涂层表现出优异的抗菌性能和耐洗性。经过 50 次连续洗涤循环后，对金黄色葡萄球菌和大肠杆菌的抑菌率（BR）仍保持在 95%以上。它在运动服、袜子和医用纺织品等多种领域具有潜在的应用。
