Abstract

The combined use of insect repellent (IR) and antimicrobial (AM) agents on textiles offers a promising approach to combating microbial and viral threats. This study presents a novel method for covalently bonding IR-containing microcapsules and AM agents onto hyperbranched polyethylenimine (PEI)-functionalized nylon-cotton (NyCo) fabric for prolonged protection. Geraniol essential oil, encapsulated in a gelatin/gum arabic shell, serves as the IR agent, while polyhexamethylene biguanide (PHMB) is covalently attached via a cyanuric chloride-based reactive dyeing method. Covalent attachment was confirmed using FTIR and ninhydrin assays, and morphological characterization was conducted via optical, fluorescent and scanning electron microscopy. A complete protection time assay and wash durability tests showed sustained IR efficacy (5–13 days), while direct-contact tests confirmed strong AM activity, achieving 99% bacterial reduction. Notably, both functionalities remained effective without adversely affecting each other. These findings highlight the potential of durable AM/IR-coated textiles for enhanced protective applications.

复合抗菌剂与驱虫微胶囊在织物上协同作用的研究

在纺织品上联合使用驱虫剂（IR）和抗菌剂（AM）为对抗微生物和病毒威胁提供了一种很有前途的方法。本研究提出了一种将含红外微胶囊和AM剂共价结合到超支化聚乙烯亚胺（PEI）功能化尼龙-棉（NyCo）织物上的新方法，以延长保护时间。香叶醇精油包被在明胶/阿拉伯胶壳中，作为红外剂，而聚六亚甲基双胍（PHMB）通过基于三聚氰胺的活性染色方法共价附着。通过FTIR和ninhydrin检测确认共价附着，并通过光学、荧光和扫描电镜进行形态表征。完整的保护时间测定和洗涤耐久性试验显示持续的红外效能（5-13天），而直接接触试验证实了强大的AM活性，达到99%的细菌减少。值得注意的是，这两种功能都保持有效，而不会相互产生不利影响。这些发现突出了耐用AM/ ir涂层纺织品在增强防护应用方面的潜力。
