▎ 摘 要
NOVELTY - The anti-coronavirus non-woven fabric (3) comprises nano silver and an inorganic agent and/or an organic agent. The inorganic agent comprises nano titanium dioxide, nano zinc oxide, nano bismuth tungstate and/or nano silicon dioxide. The organic agent comprises chitosan and/or a quaternary ammonium salt. USE - Anti-coronavirus non-woven fabric used in mask (claimed). ADVANTAGE - The fabric endows the mask with long-acting, anti-haze, anti-epidemic and anti-coronavirus performances (against H1N1 and H3N2) while not affecting the air permeability, has a catalytic degradation function on harmful gases such as formaldehyde and benzene in the air, can be repeatedly washed and recycled, and greatly reduces the use cost of the protective mask. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: a mask comprising a first fabric layer, the anti-coronavirus non-woven fabric, and a second fabric layer, which are arranged in order from the inside to the outside; and a preparation method of the anti-coronavirus non-woven fabric, which invovles either mixing nano silver sol, an inorganic agent and/or an organic agent to prepare sol, soaking the non-woven fabric in the sol, and drying, flattening and rolling, or mixing nano-silver doped inorganic agent, fiber material and solvent, and performing electrostatic spinning to obtain the coronavirus-resistant non-woven fabric, mixing nano silver sol, inorganic agent and/or organic agent to prepare sol, mixing a nano-silver doped inorganic agent, a fiber material and a solvent, and performing electrostatic spinning to obtain a non-woven fabric and soaking the non-woven fabric in the sol, drying, flattening and rolling. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a mask of an anti-coronavirus non-woven fabric. 1First fabric layer 2Haze-proof filter layer 3Anti-coronavirus non-woven fabric 4Second fabric layer
