Abstract

The development of multifunctional cotton fabrics that are stain-resistant, antimicrobial, and easy to clean has sparked scientific interest as well as practical usefulness, owing to its medical and healthcare applications. The purpose of this study was to fabricate self-cleaning and antimicrobial cotton for final use by soaking the cotton fabric in nonfluorinated hybrid formulations based on quaternary chitosan-silane using the sol-gel process. The fluorine-free cotton fabric demonstrated high self-cleaning behavior and outstanding bacterial killing efficacy against E. coli and S. aureus bacteria, without altering the desired textile properties of cotton fabric. Remarkably, cotton textiles using the hybrid formulations HTACC-VTES (N-(2-hydroxy)propyl-3-trimethylammonium chitosan chloride-vinyltriethoxy silane) and TMCC-VTES (N, N, N-trimethyl chitosan chloride-vinyltriethoxy silane) demonstrated promising water contact angles of 147° and 142° respectively, indicating a move toward superhydrophobicity. In FTIR spectra, both treated cotton textiles had an absorption peak at 1208 cm^-1 (SiOC bending), indicating a stronger interaction between silane binding agents and the cotton substrate. The treated cotton fabric with desirable features retains its stability and endurance after 12 cycles of washing for antibacterial tests and 15 cycles for wettability tests. The manufactured cotton fabric has several potential applications, such as in personal hygiene items and medical applications.

制造具有微生物抗粘活性的抗菌棉织物生物基复合材料。

多功能棉织物具有抗污、抗菌和易清洁的特性，由于其在医疗和保健方面的应用，这种织物的开发引发了科学界的兴趣，同时也具有实用性。本研究的目的是利用溶胶-凝胶工艺，将棉织物浸泡在基于季甲壳素-硅烷的无氟混合配方中，从而制造出最终使用的自清洁抗菌棉织物。这种无氟棉织物具有很高的自洁性能，对大肠杆菌和金黄色葡萄球菌具有出色的杀菌效果，同时不会改变棉织物所需的纺织特性。值得注意的是，使用 HTACC-VTES（N-(2-羟基)丙基-3-三甲基氯化壳聚糖-乙烯基三乙氧基硅烷）和 TMCC-VTES（N，N，N-三甲基氯化壳聚糖-乙烯基三乙氧基硅烷）混合配方的棉织物显示出良好的水接触角，分别达到 147°和 142°，表明它们正向超疏水方向发展。在傅立叶变换红外光谱中，两种处理过的棉织物在 1208 cm-1 处都有一个吸收峰（SiOC 弯曲），表明硅烷结合剂与棉基质之间的相互作用更强。经过处理的棉织物具有理想的特性，在抗菌测试中经过 12 次洗涤，在润湿测试中经过 15 次洗涤后，仍能保持其稳定性和耐久性。制成的棉织物具有多种潜在用途，如个人卫生用品和医疗应用。
