There is an urgent need to develop novel antimicrobial cotton textiles (CT) because microbial contamination is one of the greatest threats to public health due to the emerging of infectious diseases and drug-resistant pathogens. In this work, an isocyanate group containing borneol-based antimicrobial finishing agent (NCO-B) was developed which can be covalently grafted to the surface of cotton textiles by a simple one-step method. The obtained NCO-B-finished CT (NCO-B-CT) exhibited broad-spectrum antimicrobial adhesion properties against bacteria (E. coli), including superbugs (MRSA), and fungi (A. niger). Due to its unique antimicrobial mechanism of borneol stereochemistry, the obtained NCO-B-CT is a non-releasing antimicrobial material which causes no skin sensitization and has no cytotoxicity. The mechanical properties of the CT were also improved after this finishing process. Additionally, it displayed durable washing fastness and antimicrobial adhesion properties by bearing 50 times laundering cycles. Therefore, this material may have great potential for application in multifunctional textiles, flexible skin electronics and medical protection.

用天然冰片基整理剂装饰的耐用抗超级细菌粘附棉纺织品
迫切需要开发新型抗菌棉纺织品 (CT)，因为由于传染病和耐药病原体的出现，微生物污染是对公众健康的最大威胁之一。在这项工作中，开发了一种含异氰酸酯基的冰片基抗菌整理剂（NCO-B），它可以通过简单的一步法共价接枝到棉纺织品表面。获得的 NCO-B-finished CT (NCO-B-CT) 对细菌 (大肠杆菌) 表现出广谱抗菌粘附特性，包括超级细菌 (MRSA) 和真菌 ( A. niger )）。由于其独特的冰片立体化学抗菌机理，所得到的NCO-B-CT是一种不引起皮肤致敏、无细胞毒性的非释放型抗菌材料。CT 的机械性能在此精加工过程后也得到了改善。此外，它通过承受 50 次洗涤循环，显示出持久的耐洗牢度和抗菌粘附性能。因此，这种材料在多功能纺织品、柔性皮肤电子和医疗防护方面可能具有巨大的应用潜力。
