Fabric materials are disclosed that have been treated with a water resistant and antimicrobial treatment. The water resistant and antimicrobial treatment includes a combination of a durable water resistant composition and an antiviral composition. Protective garments can be made from the fabric that provide protection against airborne pathogens by preventing penetration through the fabric material and by destroying any pathogens that land upon the fabric.

A loose-leaf glove is provided, including a dorsum top layer and a palm inner layer. The periphery of the dorsum top layer is combined with the periphery of the palm inner layer, and the palm inner layer is formed by plural palm inner surfaces. The peripheries of the plural palm inner surfaces are overlapped and combined. A tear line is imprinted at a place where the periphery of the dorsum top layer is combined with the periphery of the palm inner layer. Each palm inner surface can escape from the dorsum top layer by tearing the tear line apart. The separated palm inner surface is discarded, and a next palm inner surface is used instead.

Apparatuses of electrochemical antimicrobial face masks and methods for manufacturing the same are provided. In one embodiment, an electrochemical antimicrobial face mask may include an electrochemical antimicrobial section configured to inactivate microbes that are in contact with the electrochemical antimicrobial section, and a filtration section configured to provide additional protection that prevents a user from breathing in the microbes, and where the electrochemical antimicrobial section is attached to the filtration section. The electrochemical antimicrobial section may include a galvanic corrosion cell membrane configured to generate antimicrobial agents via a galvanic electrochemical reaction, a hydrophilic antimicrobial membrane configured to inactivate microbes using the antimicrobial agents, and a regeneration pad configured to supply materials to the galvanic corrosion cell membrane for generating the antimicrobial agents.

A face mask (100) may comprise at least one layer of filtration material (218) configured to filter one or more harmful substances from the air breathed by a user; at least one layer of absorbent material (214) configured to absorb moisture exhaled by the user, wherein the at least one layer of absorbent material (214) spans the entire inner surface area of the mask (100); at least one layer of waterproof material (216) located between the at least one layer of filtration material (218) and the at least one layer of absorbent material (214) configured to prevent moisture from the absorbent material from contacting the filtration material; and at least one layer of anti-bacterial material (212) located adjacent to the at least one layer of absorbent material (214) and forming the inner surface of the mask (100). The face mask (100) can absorb moisture exhaled by a user.

A personal protective device (PPE) comprising a face cover assembly and a bodysuit configured to be worn by a human user. The device protects users against airborne aerosol particles containing viruses or other infectious agents while enabling improved flexibility relative to prior art designs. The device includes a helmet-like” rotating face cover assembly that fits over the user's head and attaches to a collar on the biohazard bodysuit. This rotating face cover assembly has a plurality of different mask sides, each with differing geometries or other properties. The device enables a user to rotate (either manually or by electric motor) the masks and select a given mask side that best meets that user's needs. The different mask sides can accommodate different facial geometries, eyewear types, and use cases, such as operation in more hostile environments.

The disclosure provides application of sulfated polysaccharides in resisting novel coronavirus, belonging to the technical field of biomedicine. It is confirmed in the disclosure that by binding to an S protein on the surface of the SARS-CoV-2 virus, the sea cucumber polysaccharides, fucoidans or carrageenans can prevent cell membranes of body cells from adsorbing and internalizing the SARS-CoV-2 virus, thereby preventing the SARS-CoV-2 virus from infecting the body cells, which indicates that the sea cucumber polysaccharides, fucoidans or carrageenans have the effect of prevention and treatment of pneumonia caused by the novel coronavirus. These polysaccharides can be used to prepare protective articles having functions of prevention and treatment of novel coronavirus infection, for example: inhalations, hand lotions, oral liquids and respirators.

Provided is graphene-based personnel protection equipment (PPE) product, comprising: (a) a fabric, clothing, face shield, face mask, or glove body configured to support graphene sheets; and (b) graphene sheets deposited on a surface of the body or at least partially embedded in the body, wherein the graphene sheets comprise a plurality of discrete single-layer or few-layer graphene sheets selected from pristine graphene, graphene oxide, reduced graphene oxide, graphene fluoride, graphene chloride, graphene bromide, graphene iodide, hydrogenated graphene, nitrogenated graphene, doped graphene, chemically functionalized graphene, or a combination thereof. Preferably, surfaces of graphene sheets carry an anti-microbial compound, preferably in the form of a nanoparticle, nano-wire, or nano-coating.

A fabric that includes a loop of a yarn including a voltage generating filament. The fabric has a value of X of 1,000 or more, where X=(A+B)×C×D×E, and wherein: A is a loop angle of the loop of the yarn when the fabric is stretched by 10%, B is a connection angle of the loop of the yarn when the fabric is stretched by 10%, C is a number of the loops of the yarn per 1 cm.sup.2 of the fabric, D is a force (N) applied per basis weight (g/m.sup.2) of the fabric, and E is a surface potential (V) of the yarn.
