Antibacterial textiles, which effectively inhibit bacterial breeding and resist pathogenic diseases, have wide applications in medicine, hygiene, and related fields. However, traditional antibacterial textiles exhibit significant limitations, such as poor antibacterial durability and contamination during preparation. In this work, nanofiber yarn loaded with a high-efficiency antibacterial agent was prepared using electrospinning technology. Polyethyleneimine (PEI) was introduced as a solubilizing material to functionalize graphene oxide (GO) to form GO-PEI composites. A facile microwave heating method was used to synthesize GO-PEI and silver nanoparticles (AgNPs). A multi-needle conjugated electrospinning device was used to blend the nanofibers with the GO-PEI-Ag composite to form a nanofiber core-spun yarn. The antibacterial agent was firmly fixed on the fiber to prevent easy removal. A uniformly oriented yarn structure and internal morphology were observed, and the antibacterial activity of the fabric was measured. The antibacterial rate of the fabric was over 99.99%for both Escherichia coli and Staphylococcus aureus. After ten washes, the antibacterial rate remained above 99.99%. Thus, nanofiber fabric from electrospinning displays high antibacterial activity and excellent durability, thereby providing a feasible methodology for future production of antibacterial textiles.
抗菌纺织品能够有效抑制细菌繁殖并抵抗致病性疾病，在医学、卫生及相关领域有着广泛应用。然而，传统抗菌纺织品存在显著局限性，如抗菌耐久性差以及制备过程中的污染问题。在本研究中，采用静电纺丝技术制备了负载高效抗菌剂的纳米纤维纱线。引入聚乙烯亚胺（PEI）作为增溶材料对氧化石墨烯（GO）进行功能化，以形成GO-PEI复合材料。采用简便的微波加热方法合成了GO-PEI和银纳米颗粒（AgNPs）。使用多针共轭静电纺丝装置将纳米纤维与GO-PEI-Ag复合材料共混，形成纳米纤维包芯纱。抗菌剂牢固地固定在纤维上，不易脱落。观察到纱线具有均匀的取向结构和内部形态，并对织物的抗菌活性进行了测定。该织物对大肠杆菌和金黄色葡萄球菌的抗菌率均超过99.99%。经过十次洗涤后，抗菌率仍保持在99.99%以上。因此，静电纺丝制备的纳米纤维织物具有高抗菌活性和优异的耐久性，为未来抗菌纺织品的生产提供了一种可行的方法。
