Fabric capable of inhibiting bacteria and viruses, and preparation method thereof, and protective clothing prepared from fabric

The invention discloses a fabric capable of inhibiting bacteria and viruses. The fabric comprises an isolating layer, a composite salt coating and an ionizing layer, wherein the isolating layer is theinner layer of the fabric, the composite salt coating serves as the middle layer of the fabric and is prepared by dip-coating or spraying a base material with a composite salt solution, the base material can be made of a porous material such as a non-woven fabric or gauze and the like, the composite salt coating can dehydrate and inactivate bacteria and viruses attached to the base material, thecrystalline salt of the composite salt coating can pierce bacteria and viruses to kill the bacteria and the viruses, the ionizing layer serves as the outermost layer of the fabric, is made of a metalnet, is connected with a high-voltage pulse generator and kills bacteria and viruses through high-voltage low-current pulse discharge. According to the invention, the fabric can dehydrate and inactivate bacteria and viruses con
