A filter or mask structure, comprising a first face layer comprising a polymer and having a face basis weight, a second outer layer comprising a polymer and having an outer basis weight less than 34 gsm, and a third outer layer comprising a polymer and having a third basis weight and disposed between the first face layer and the second outer layer. At least one of the layers further comprises an AM/AV compound. The mask structure demonstrates an Escherichia coli efficacy log reduction greater than 4.0, as measured in accordance with ASTM E3160 (2018) and a particulate filtration efficiency greater than 90%, as measured in accordance with ASTM F2299-03R17.

A face mask include a bulbous area that reduces contact between the wearer and the mask, with the inner surface texture and material adapted to be comfortable to the wearer. The bulbous area may be equipped with a filter retained by slots at the edge of the bulbous area, with the inner surface texture and material of the filter also adapted to be comfortable to the wearer. The mask may be knit with seamless transitions between wearer-contacting surfaces and the bulbous area, which enhance the comfort of the mask. The mask may include silvered yarns for antimicrobial properties. Furthermore, the bulbous area increases the effective surface area of the mask on both inhalation and exhalation, unlike pleats that collapse on inhalation.

(1) The elastic nonwoven fabric includes a resin composition containing a specific low-crystalline polypropylene, and an -olefin copolymer A containing an ethylene-derived constitutional unit and a propylene-derived constitutional unit, and having a melting point of 100 C. or more and a crystallization degree of 15% or less. (2) The resin composition contains from 5 parts by mass to 50 parts by mass of the -olefin copolymer A with respect to 100 parts by mass of the resin composition.

A nonwoven fabric is disclosed. The nonwoven fabric can include a first surface and a second surface and at least a first visually discernible zone of three-dimensional features on one of the first or second surface. Each of the three-dimensional features can define a microzone comprising a first region and a second region. The first and second regions can have a difference in values for an intensive property, and the first visually discernible zone can exhibit a high visual resolution.

A thermoset composite and method for producing the same is provided. The method includes: providing at least one surface veil layer that includes a fibrous layer saturated with a water based binder, and one or more composite constituent layers; applying an amount of thermoset resin to the composite constituent layers; arranging the surface veil layer and the composite constituent layers in a stack; and producing the thermoset composite by pulling the composite constituent layers and the surface veil layer through a forming die.
