In this study, nanoparticle-incorporated nanofiber-covered yarns were prepared using a custom-made needle-free electrospinning system. The ultimate goal of this work was to prepare functional nanofibrous surfaces with antibacterial properties and realize high-speed production. As antibacterial agents, we used various amounts of copper oxide (CuO) and vanadium (V) oxide (VO) nanoparticles (NPs). Three yarn preparation speeds (100 m/min, 150 m/min, and 200 m/min) were used for the nanofiber-covered yarn. The results indicate a relationship between the yarn speed, quantity of NPs, and antibacterial efficiency of the material. We found a higher yarn speed to be associated with a lower reduction in bacteria. NP-loaded nanofiber yarns were proven to have excellent antibacterial properties against Gram-negative (). CuO exhibited a greater inhibition and bactericidal effect against than VO. In brief, the studied samples are good candidates for use in antibacterial textile surface applications, such as wastewater filtration. As greater attention is being drawn to this field, this work provides new insights regarding the antibacterial textile surfaces of nanofiber-covered yarns.
在这项研究中，使用定制的无针电纺系统制备了纳米颗粒复合纳米纤维覆盖纱线。这项工作的最终目标是制备具有抗菌性能的功能性纳米纤维表面，并实现高速生产。作为抗菌剂，我们使用了不同量的氧化铜（CuO）和氧化钒（VO）纳米颗粒（NPs）。对于纳米纤维覆盖纱线，使用了三种纱线制备速度（100 m/min、150 m/min 和 200 m/min）。结果表明，纱线速度、NP 数量和材料的抗菌效率之间存在关系。我们发现较高的纱线速度与细菌减少量较低有关。负载 NP 的纳米纤维纱线被证明对革兰氏阴性菌（）具有优异的抗菌性能。CuO 对 的抑制和杀菌效果大于 VO。简而言之，研究样品是抗菌纺织品表面应用（如废水过滤）的良好候选材料。随着人们对该领域的关注度不断提高，这项工作为纳米纤维覆盖纱线的抗菌纺织品表面提供了新的见解。
