Abstract:
Various embodiments of a filtering face-piece respirator and a method of making such respirator are disclosed. In one or more embodiments, the filtering face-piece respirator includes a mask body and a harness attached to the mask body. The mask body includes a corrugated filtering structure including peaks separated by valleys, and bridging filaments that are in discontinuous contact with at least one of an interior surface and an exterior surface of the corrugated filtering structure. The bridging filaments are attached to at least some of the peaks.
Abstract:
Various embodiments of a respirator are disclosed. The respirator can include a mask body and one or more elastic straps that are secured to the mask body on opposing sides. The elastic straps can have an openwork construction and can include a netting that has an array of polymeric strands periodically joined together at bond regions throughout the array. In one or more embodiments, the openwork elastic straps are lighter and more breathable than conventional straps. This improvement in breathability can make the respirator more comfortable to wear.

Abstract:
A filtering face-piece respirator 10 that comprises a mask body 12 and a harness 14. The mask body 12 includes a supporting frame structure 16 and a filtering structure 18. The frame structure is injection molded onto the filtering structure 18 such that the frame structure 16 becomes bonded to the filtering structure 18. A mask body having such a support structure allows the filtering structure to follow its configuration closely, providing improved aesthetics and collapse resistance to the resulting article.
