The invention discloses an antibacterial medical coated non-woven fabric and a preparation method thereof. First, nano-zinc oxide whiskers and nano-titanium dioxide whiskers are modified by using a silane coupling agent, and the modified whiskers are mixed into spinning stock solution Spinning and making a non-woven matrix; Loading sustainable release Ag + on graphene oxide to obtain modified graphene oxide, adding modified graphene oxide and lauric anhydride to coating A and coating on the non-woven fabric. The lower surface of the woven fabric substrate; the antibacterial microcapsules and porous starch are mixed into the coating layer B and coated on the upper surface of the non-woven fabric substrate, and the antibacterial type coated non-woven fabric is obtained by irradiation with an ultraviolet lamp; The synergistic effect of layer A, coating B and non-woven fabric matrix, the prepared antibacterial medical coated non-woven fabric has excellent antibacterial properties, the strongest hemostatic effect, high tensile breaking strength, water soluble, and has a very broad application prospects. |
