摘要： An article of personal protective equipment. The article has an external side for facing side the environment and an internal side for facing the body of a user. The article is air permeable but has a porosity sufficient to entrap and thereby filter selected infectious agents (I As). The one or more layers provide (1) disabling disruption of the IAs by oligodynamic or electroceutical effects and/or (2) moisture management effects.

摘要： A filtration device against breathing in of small particles or virus, comprising a filtering membrane for air filtration, at a distance to the face to create a large space of the filtered air and a large active area of the filtering membrane for easy breathing and for low resistance, which the filtering membrane puts up to the flowing of the filtered air, wherein, die space of the filtered air includes a free space under the nose and a free space under the chin flowing of the breathed out air directed through the nose around the chin to the neck. The breathed out air is discharged through an active area of the filtering membrane into the free space and/or the filtering membrane by moving away to a distance from the cheeks creates a large space in front of the cheeks of the face flowing of air to the sides and creates a large active area of the filtering membrane extending to the sides up to a few mm from the ears, wherein the large space of the filtered air in the space at the ears, is realized by an offset or by a step offset.

摘要： A blended polymer comprising, an amorphous thermoplastic polymer and a thermoplastic semi-crystalline polymer, each of the polymers being essentially miscible in the other and being blended at a weight ratio of amorphous polymer/semi-crystalline polymer of greater that 0.05 to about 20 forms a melt blown nonwoven fabric having essentially no defects with long fiber lengths having uniform diameters. The nonwoven fabrics when used as a filter may have greater than 95% efficiency at a pressure drop of less than 2 mm Hg even after being exposed to high temperatures (~70°C) for an hour or more.

摘要： A face covering (100) is configured to obscure the nose and the mouth of a wearer. The face covering includes an upper portion (104) including a free lower edge (120) and a lower portion (106) coupled to the upper portion, and the lower portion includes a free upper edge (124). The free lower edge and the free upper edge are relatively movable to provide an opening therebetween, and the opening (126) is configured to permit a mouthguard to pass through the face covering.
