    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: An incrementally activated laminate that includes an incrementally activated fibrous web and a film having alternating first and second regions and a laminate of the film and an extensible fibrous web. The first region of the film includes a first polymeric composition, and the second regions include an elastic polymeric composition that is more elastic than the first polymeric composition. In the incrementally activated laminate, the distance between midpoints of two first regions separated by one second region is smaller than the activation pitch, and the first regions are not plastically deformed. In the extensible laminate, a tensile elongation at maximum load of the film is up to 250 percent of the tensile elongation at maximum load of the extensible fibrous web. Methods of making the laminates are also described.

    Abstract: A system including a polymeric sheet. The polymeric sheet comprises a base sheet having a first surface and a second surface opposite the first surface and a multiplicity of spaced rails projecting from the first surface of the base sheet. The rails comprise a stem portion attached to and substantially upright from the first surface of the base sheet and a top portion on the distal end of the stem opposite the base sheet. The top portion comprises a first surface opposite the base sheet and a second surface facing the first surface of the base sheet. Additionally, the rails have a length greater than the width of the stems. The first surface of the base sheet, the second surface of the top portion and the surface of the stem defines a cavity with walls, and an adhesive coated on at least a portion of the cavity wall.
