摘　　要：针对现有抗菌纺织品加工方法存在问题,利用静电纺喷技术,将接枝有机硅季铵盐的氧化石墨烯(GO-QAS)均匀喷射在棉网表面,经后序集聚加捻,构建GO-QAS/棉复合纱线。结果表明:当纺丝电压为35 kV、棉网厚度为3 mm、GO-QAS质量浓度为4 mg/mL时,GO-QAS在静电力作用下能够稳定喷射在棉网表面,同时GO-QAS包裹卷绕在棉纤维表面;进一步集聚加捻获得的GO-QAS/棉复合纱线也显示了优异的力学性能,并对大肠杆菌和金黄葡萄球菌具有大于99.99%的抗菌性。基于静电纺喷工艺路线,通过对氧化石墨烯不同的功能改性,还可制备多重功能因子组合的复合纱线,从而实现纱线的多功能改性。Antibacterial textiles are the first barrier for human body to resist external bacteria and play an important role in improving personal hygiene environment and ensuring human health. Especially after the outbreak of COVID-19 in 2020, antibacterial textiles are favored by more and more people because they can inhibit the propagation of microorganisms, avoid cross infection of bacteria, and prevent the spread of diseases, thus resulting in a substantial increase in demand. As the yarn is the basic component of textiles, it is a simple and effective way to directly construct antibacterial textiles through antibacterial yarns. However, the processing methods of antibacterial yarns widely used in industry have many problems, such as heavy pollution, high energy consumption and unstable antibacterial performance. Therefore, it is of great research value to further develop the green processing method of antibacterial yarns and improve the yarns’ antibacterial property.In view of the existing problems of antibacterial yarns and their processing methods, a new method for fabricating antibacterial blended yarns embedded in graphene is proposed in this paper from the perspective of physical modification based on the principle of electro-spraying. Namely, an organic silicon quaternary ammonium salt(QAS) is first grafted onto graphene oxide by coupling reaction to synthesize nano-composite antimicrobial agents(GO-QAS), in which QAS and GO are respectively used as main antibacterial substance and functional modification carrier. Then, GO-QASs are uniformly sprayed onto the cotton web by electrostatic action to form a GO-QAS/cotton hybrid web. Finally, the GO-QAS/cotton hybrid web is aggregated and twisted into a GO-QAS/cotton blended yarn with antibacterial function. The morphology and chemical structure of GO-QAS antibacterial agent are characterized by scanning electron microscope, Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. The distribution rule and existing form of GO-QAS antibacterial
