Non-woven protective clothing against blood and viruses

A non-woven protective clothing against blood and viruses, comprising:

• a non-woven fabric layer, which has two surfaces, with a basis weight ≤70 g/m2;
• a moisture-permeable layer, which is a porous film, with a basis weight between 5˜30 g/m2;
• the percentage by weight of a powder in the moisture-permeable layer is 40˜70%, and the draw ratio thereof is ≤400%;
• moreover, the average grain diameters in the powder in the moisture-permeable layer are 0.5˜3 μm, and calcium carbonate (CaCO3) is used as the powder, and the moisture-permeable layer is laminated to one of the surfaces of the non-woven fabric layer;
• an elastic pore filling layer, which is a hydrophilic polyurethane that is composed of at least a hydrophilic waterborne polyurethane and a hydrophilic solventborne polyurethane, wherein, the elastic pore filling layer is coated or printed onto the surface of the moisture-permeable layer, and the thickness of the elastic pore filling layer is thinner than that of the moisture-permeable layer;
• wherein a moisture permeability of the elastic pore filling layer is lower than a moisture permeability of the moisture-permeable layer;
• wherein, the synthetic blood permeability of the non-woven protective clothing against blood and viruses being capable of resisting pressure of 2.0 psi for 1 minute, and the Phi-X174 bacteriophage penetrability thereof being capable of resisting pressure of 2.0 psi for 1 minute.
