The embodiment of the invention provides an antibacterial anti-
virus washable multifunctional 
mask and a preparation method thereof. The 
mask comprises a 
mask body and two ear bands, wherein the maskbody comprises two composite protective 
layers which are oppositely overlapped and sewn; each composite protective layer comprises a 
polyester fiber long 
fiber fabric layer and a 
polyester fiber shortfiber fabric layer arranged on the 
polyester fiber long fiber fabric layer; therefore, the mask body with the four protective 
layers is made of polyester, the mask has good crease resistance, 
water resistance and antifouling property, good conformality, repeatable cleaning, the repeated use frequency is up to 50 times; 
medical waste and reducing 
ambient pressure are reduced, an antiviral auxiliary agent and an antibacterial auxiliary agent are treated by an atomizer and permeate into the fiber structures of the composite protective 
layers; the mask has the advantages that the anti-
virus and anti-bacterial functions are achieved, the fabric is high in 
water resistance and breathability, the face is not prone to stuffiness and sweating, the mask is suitable for long-term wearing, in addition, an far-
infrared auxiliary permeates into the composite protective layers in an atomization mode, and therefore the mask has the health care function.
