The invention belongs to the technical field of daily protection products, in particular to a filter cloth material for a mask with self-antibacterial and self-disinfecting functions and a manufacturing method thereof. The specific implementation process comprises the steps of discharging, degreasing, washing, acid pickling, sensitizing, washing, activating, pre-silvering, silvering, washing, surface modifying, drying, collecting and the like, and proper nano-silver particles can be deposited on the fiber surface after a conventional mask filter material is treated by the method, so that the killing effect on microorganisms such as bacteria or viruses is realized. According to the technology, the defect that an existing mask filter material can only filter particulate matter or droplets but cannot exterminate bacteria or viruses can be overcome; meanwhile, the nano-silver particles and the filter material fibers are firmly combined and are only distributed on the surfaces of the filtermaterial fibers, and compared with other silver-containing filter materials, the nano-silver filter material has the advantages of continuous industrial production, high effective utilization rate ofsilver, strong binding force of the silver particles and the filter material fibers, low manufacturing cost and the like.
