  • Patent number: 11998073
    Abstract: A non-woven protective clothing against blood and viruses is composed from a non-woven fabric layer, which has two surfaces; and a moisture-permeable layer, which is a porous film that is laminated to one of the surfaces of the non-woven fabric layer; and an elastic pore filling layer, which is a hydrophilic polyurethane. 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. The synthetic blood permeability of the non-woven protective clothing against blood and viruses can resist a pressure of 2.0 psi for one minute, and the Phi-X174 bacteriophage penetrability thereof can resist a pressure of 2.0 psi for one minute.

  • Publication number: 20230041219
    Abstract: A non-woven protective clothing against blood and viruses, which is composed from: a non-woven fabric layer, which has two surfaces; and a high waterproof moisture-permeable layer, which is a porous film that is laminated to one of the surfaces of the non-woven fabric layer; and an elastic pore filling layer, which is a hydrophilic polyurethane. The elastic pore filling layer is coated or printed onto the surface of the high waterproof moisture-permeable layer, and the thickness of the elastic pore filling layer is thinner than that of the high waterproof moisture-permeable layer. The synthetic blood permeability of the non-woven protective clothing against blood and viruses can resist a pressure of 2.0 psi for one minute, and the Phi-X174 bacteriophage penetrability thereof can resist a pressure of 2.0 psi for one minute.

  • Publication number: 20220205171
    Abstract: The present invention provides a waterproof, moisture-permeable composite non-woven fabric able to block viruses and blood, and consists of a non-woven fabric, which is provided with two surfaces and has a basic weight of ?70 g/m2; and a multi-layer breathable membrane, which is at least a three-layer co-extruded membrane. The basic weight of the multi-layer breathable membrane lies between 5˜30 g/m2 and is attached to one of the surfaces of the non-woven fabric. A powder in the multi-layer breathable membrane has a percentage by weight of 40˜60% and an extension ratio ?300%. The present invention has characteristics including a synthetic blood permeability able to resist pressure of 2.0 psi sustainable for at least one minute, a Phi-X17 bacteriophage penetrability able to resist pressure of 2.0 psi sustainable for at least one minute, and a moisture capacity ?1500 g/m2·24 hr.
