摘要： A filtering face-piece respirator 10 that comprises a mask body 12 and a harness 14 that is attached to the mask body 12. The mask body 12 comprises a shaping layer 20 and a filtering structure 22 that contains a filtering layer 32. The filtering structure 22 also comprises an outer cover web 36b that includes colored melt-blown fibers and staple fibers. The use of colored melt-blown fibers and staple fibers in an outer cover web provides the respirator with a mottled colored appearance—that is, the color does not appear uniform over the outer surface of the outer cover web.

摘要： A respirator 10 that has a mask body 12 and a harness 14 that is attached to the mask body 12. The mask body 12 includes a filtering structure 18 that has an inner cover web 40a, an outer cover web 40b that comprises melt-blown fibers and staple fibers, and a filtration layer 42 that is located between the inner and outer cover webs 40a, 40b. The mask body 12 also has a mesh 20 that is joined to the outer cover web 40b. A respirator having this construction is more resistant to inward collapse of the filter media during breathing and is more aesthetically pleasing.

摘要： A pleated filter is made from a monocomponent monolayer nonwoven web containing a bimodal mass fraction/fiber size mixture of intermingled larger size and smaller size continuous monocomponent polymeric fibers of the same polymeric composition. Rows of pleats are formed in the nonwoven web, and the pleated web is cut to a desired size and shape to provide a filter element containing a self-supporting porous monocomponent monolayer matrix of fibers bonded to one another at least some points of fiber intersection and having an average initial submicron efficiency of at least 15% at a 1.52 meters/sec face velocity. The filter element is deformation resistant without requiring stiffening layers, bicomponent fibers or other reinforcing measures in the filter media layer.

摘要： A pleated filter is made from a monocomponent monolayer nonwoven web of continuous monocomponent meltspun partially crystalline and partially amorphous oriented fibers of the same polymeric composition that are bonded to form a coherent and handleable web having a Gurley Stiffness of at least 100 mg and which further may be softened while retaining orientation and fiber structure. Rows of pleats are formed in the nonwoven web, and the web is cut to a desired size and shape to provide a pleated filter element containing a self-supporting porous monocomponent monolayer matrix of fibers bonded to one another at least some points of fiber intersection and having an average initial submicron efficiency of at least 15% at a 1.52 meters/sec face velocity. The filter element is deformation resistant without requiring stiffening layers, bicomponent fibers, adhesive or other reinforcement in the filter media layer.

摘要： A molded respirator is made from a monocomponent monolayer nonwoven web containing a bimodal mass fraction/fiber size mixture of intermingled continuous monocomponent polymeric microfibers and larger size fibers of the same polymeric composition. The respirator is a cup-shaped porous monocomponent monolayer matrix whose matrix fibers are bonded to one another at least some points of fiber intersection.

摘要： A flat-fold respirator is made from a stiff filtration panel joined to the remainder of the respirator through at least one line of demarcation. The panel contains a porous monocomponent monolayer nonwoven web that contains charged intermingled continuous monocomponent polymeric fibers of the same polymeric composition and that has sufficient basis weight or inter-fiber bonding so that the web exhibits a Gurley Stiffness greater than 200 mg and the respirator exhibits less than 20 mm H2O pressure drop. The respirator may be formed without requiring additional stiffening layers, bicomponent fibers, or other reinforcement and can be flat-folded for storage. Scrap from the manufacturing process may be recycled to make additional stiff filtration panel web.
