摘　　要：将二氧化硅(SiO_(2))和氧化锌(ZnO)纳米粒子添加到纺丝液中,利用静电纺丝将SiO_(2)/ZnO/PU纳米纤维沉积在均匀输送的棉网上,通过传统纺纱工艺制成远红外/抗菌多功能纳米纤维纱线,并对其织物的远红外发射率和抗菌性能进行表征。结果显示:SiO_(2)和ZnO粒子的协同作用可有效增强织物的远红外发射功能,其发射率随纳米粒子质量分数的增加而升高;质量分数为6%时,纳米纤维纱线具有较好的形貌与力学性能,同时具有较高的远红外发射率和优异的抗菌性能,远红外发射率为0.896,对大肠埃希菌和金黄色葡萄球菌的抑菌率为99.99%。SiO_(2)and ZnO nanoparticles are added to the spinning solution,and SiO_(2)/ZnO/PU nanofibers are deposited on the evenly conveyed cotton web by electrospinning.The far-infrared/antibacterial multifunctional nanofiber yarns are prepared by traditional spinning process,and the far-infrared emissivity and antibacterial properties of the fabric are characterized.The results show that the synergistic effect of SiO_(2)and ZnO particles could effectively enhance the far-infrared emission of the fabric,and its emissivity increases with the ncrease of the mass fraction of nano-particles.When the mass fraction of nano-particles is 6%,the nano-fiber yarn has good morphology and mechanical properties,high far-infrared emissivity and excellent antibacterial properties.The far-infrared emissivity is 0.896,and the antibacterial rate against escherichia coli and staphylococcus aureus is 99.99%.
