In some embodiments, a facemask assembly can include a strap system, a facial skirt, a filter assembly, a filter material, mounting bracket, front section, a tilt mechanism, and/or a seal-tester. In some embodiments, the facial skirt has at least two seal-layers. In some embodiments, the strap system has a crown section.

The invention relates to antimicrobial and/or antiviral fabric compositions comprising ascorbic acid, citric acid, sodium hypophosphite, or a mixture thereof. The ascorbic acid may be covalently attached to at least one cellulosic portion of the fabric composition. The invention also relates to methods for preparing such fabric compositions.

Some embodiments of the teachings herein include a fiber material for antibacterial and/or antiviral use. The fiber material may comprise: a metallic silver; and manganese(IV) oxide.

The present invention describes a facial protection element for protection against risks of exposure to infectious biological agents, such as microorganisms, like a virus with an envelope, including SARS-CoV-2 and the multidrug-resistant Gram-positive bacteria. Specifically, the present invention relates to a facial protection element of the type comprising: face shields, glasses, masks, counter shields, etc., which prevent not only direct exposure to the infectious biological agent, but rather also inactivate same once the biological agent comes into contact with the facial protection element. The facial protection element comprises a plastic material or glass with a biocidal agent coating layer.

A present invention relates to a functional mask that prevents health problems such as skin problems and bacterial growth caused by internal moisture due to a wearer's exhaled breath by providing an improved structure having an air passage filter. The present invention discloses a functional mask comprising: a first outer layer covering the mouth and nose of the face of a wearer; a second outer layer connected to an ear string, and a filtering inner layer integrally connecting the first outer layer and the second outer layer, wherein an air passage part is formed by a folded structure of the filtering inner layer, thereby allowing an exhaled breath of the wearer to be discharged through the air passage part from the functional mask.

The present disclosure provides designs for an electrically heated respirator/face mask to kill or deactivate airborne viruses and bacteria by creating a seamless thermal and/or humidity chamber/barrier around the wearer's nose and mouth area; in addition to efficiently filtering the tiny particles according to NIOSH N95 standards, it reduces the chance of contracting the disease. The designs include various combinations: a disposable or reusable N95 respirator with or without an exhalation valve, disposable or reusable medical face mask, both with or without integrated and replaceable filter layers, and a reusable respirator with filter cartridges. Each design is comprised of multiple layers with an active thermal filter with a heating element, which is made of graphene. The respirator is connected via a USB cable to a power unit. A control module is used to turn the device on and off and control the inner temperature and humidity optionally through sensors.

A headwear article that converts between a headwear configuration and a mask configuration. The headwear article has a crown for covering at least a portion of a head of a wearer, a visor attached to a front portion of the crown, and at least one mask support element coupled to the crown. From the headwear configuration, at least a portion of the rear portion of the crown is collapsible into the front portion of the crown to position the headwear in the mask configuration. In the mask configuration, the at least one mask support element is configured to secure the headwear over a portion of a face of the wearer.

The present invention provides a filter material comprising an antistatic substrate having a predefined antistatic capacity, and one or more layers of nanofibers applied on the substrate. The one or more layers of nanofibers may be fabricated to have gradient structure in various parameters including thickness of nanofiber layer, nanofiber pore size, nanofiber diameter, nanofiber content and the like to suit different filtration applications. The present invention also provides a face mask comprising the filter material and a method for making the filter material.

The present invention relates to a novel all-purpose face mask device. The device is a protective facial mask that is configured to protect a user from germs, bacteria, and pathogens. The all-purpose face mask comprises an outer layer, an inner layer, an adjustable right ear loop, an adjustable left ear loop, and an opening through both the inner layer and the outer layer, configured to be positioned near the mouth of a user when the face mask is worn. Further, the device comprises a flap component for closing the opening. The flap component can be secured in an open configuration via a twist tie mechanism, buttons, snaps, etc. In this way, the flap component can be opened when a user is consuming food or beverages without fully removing the face mask.

Provided is a textile made of filament yarn comprising a polymer composition that is durable and reusable having permanent or near-permanent antiviral properties and that includes a polymer, a metal ion, preferably a zinc and/or copper ion, and an optional phosphorus compound, wherein fibers and/or fabric formed from the polymer composition demonstrate antiviral properties and wherein the polymer is hygroscopic. The present disclosure also describes methods of forming the polymer compositions and methods of preparing fibers from the polymer composition.
