A disposable highly-protective oral-nasal mask comprises a fixing part. A notch is formed in the portion, corresponding to an oral cavity, of the fixing part. An oral cavity coverage part is arranged at the notch, corresponding to the oral cavity, of the fixing part, and is detachably connected to the fixing part. A first fold part with upward external folds is further arranged on the oral cavity coverage part. A second fold part with downward external folds is arranged on a nasal cavity coverage part. Two easily deformed components are located in accommodating cavities which are formed in the fixing part in one-to-one correspondence with the easily deformed components. Both accommodating cavities are arranged in the length direction of the fixing part. One accommodating cavity is located between the oral cavity coverage part and the nasal cavity coverage part, and the other accommodating cavity is located above the nasal cavity coverage part. As a result, air circulation parts of the oral cavity and a nasal cavity are separated to reduce the air circulation between the oral cavity and the nasal cavity.

A mask comprising: a first layer in the shape of polygon includes an upper side, a bottom side and at least two short sides; a third layer in the shape of polygon includes an upper side and a bottom side and at least two short sides, and at least two short sides, the angle of bottom side of the third layer is the same as the angle of bottom of the first layer, the third layer is arranged parallel to the first layer, and at least one short side of the first layer is joined with the at least one short side of the third layer; and a second layer has an accordion-like folding structure, wherein the accordion-like folding structure is composed of alternate mountain-shaped folding lines and valley-shaped folding lines, wherein the first layer, the second layer and the third layer form a closed bag with an opening on the upper side, and when the opening is opened, accordion-like folding structure of the second layer is propped up and expanded inside the mask to form a space for the mouth and nose.

A facemask with an exposed surface, and a silane quaternary ammonium ion or salt thereof disposed on the exposed surface. The facemask further can have a main body portion, and one or more straps extending from the main body portion. The silane quaternary ammonium ion or salt thereof is disposed on the main body and on the straps. The main body portion can include a convex side and a concave side. The silane quaternary ammonium ion or salt thereof can be further disposed on the convex side and the concave side. The silane quaternary ammonium ion or salt thereof can be one or more of: 3-(trimethoxysilyl)propyldimethyloctadecyl ammonium ion, 3-(trimethoxysilyl)propyldimethyloctadecyl ammonium chloride, 3-(trihydroxysilyl)propyldimethyloctadecyl ammonium ion, and 3-(trihydroxysilyl)propyldimethyloctadecyl ammonium chloride. A solution including the silane quaternary ammonium ion or salt thereof can be applied to the exposed surface. The solution can further include water, isopropyl alcohol, and hydrogen peroxide or hypochlorous acid.

A method implemented by a computing system comprises receiving, by the computing system and from a user device, a subject profile information that specifies a plurality of body measurements associated with one or more images of a subject that are captured by the user device. The computing device receives a selection of a garment, where the garment is associated with a category, a brand, a style, and a plurality of sizes. A sizing recommendation engine of the computing system determines, based on the plurality of body measurements, a particular size of the garment that is associated with the subject profile information. The computing system communicates the particular size to the user device.

A method of manufacturing an antiviral fiber product includes impregnating a virus-inactivating agent into a cellulose-based fiber at a temperature of 120° C. to 200° C. and a pressure of 0.0098 MPa to 0.59 MPa. The virus-inactivating agent contains: an aqueous organic acid solution containing 40 wt % to 50 wt % of organic acid partially lactonizing when dissolved in water; zinc oxide nanoparticles dispersed in the aqueous organic acid solution; and zinc salt of organic acid generated by dispersion of the zinc oxide nanoparticles into the aqueous organic acid solution.

A face contact function includes a contact member comprising a first cutting line provided in the upper left end of the mask body to form a first fastening protrusion by an external force, a first fastening protrusion cutting line provided in the lower left end of the mask body and providing a space in which the first fastening protrusion is to be fitted so as to maintain a state that the upper end is in close contact with the lower end, a second cutting line provided in the upper right end of the mask body to form a second fastening protrusion by an external force, and a second fastening protrusion cutting line provided in the lower right end of the mask body and providing a space in which the second fastening protrusion is to be fitted.

A disposable face mask includes an upper portion of the face mask and a lower portion of the face mask, the upper portion and lower portion of the face masks each adjoin monolithically formed therewith face mask straps defined by perforations in a web of material used to form the face mask and straps, wherein the perforations allow the straps to be partially separated and utilized for securing said face mask to a wearer's face. The disposable face mask may be made by perforating patterns into a web of materials to define the face mask straps and face mask body that are formed monolithically from the web of materials. The face masks may be wound on a roll for dispensing by tearing off from the roll and then separating the straps at the perforations. Alternatively, the face mask borders may be cut-through to allow dispensing of the face masks individually from bulk packaging, where the face mask is removed from the package and the straps are separated at the perforations to allow the face mask to be secured to the wearer's face by tying the straps behind the wearer's head.

The present disclosure relates to imparting a cooling effect on textiles or fabrics by treating them and incorporating sugar alcohol and carbonate compositions.

The present invention discloses a disposable mask comprising a filter body including a base and at least one connecting part fixed to the base, and at least one detachable decorative strap connected to the filter body. The present invention brings users both functionality and aesthetics.

A mask with detachable earrings includes a mask body that covers wearers' mouth and nose, and earrings respectively provided on left and right sides of the mask body, where the mask body comprises a cutting line or an unevenness portion capable of selectively attaching and detaching the earrings to and from the mask body. According to the present invention, it is possible to freely attach and detach earrings to and from a mask body even without using a separate connection tool, and it is unnecessary to install the earrings to the mask body, and thus the production amount of the mask may increase by 3 to 10 times, and the manufacturing cost of the mask may be reduced.
