摘要： Various embodiments of a respirator and a method of making such respirator are disclosed. In one or more embodiments, the respirator includes a mask body and a harness attached to the mask body. The mask body can include an outer cover web, an inner cover web, a filtration layer disposed between the outer cover web and the inner cover web, and a contrast layer disposed between the outer cover web and the inner cover web in a sinus region of the mask body. A portion of the contrast layer can be visible through an outer surface of the outer cover web to form a contrast region of the mask body, where the outer surface of the outer cover web faces away from the filtration layer.

摘要： The method of forming pleated filter media includes providing a generally planar web of filter material (12), folding the web to form a pleated web having a plurality of fold lines, arranging the plurality of pleats (24) in a first spaced configuration defined by a first distance between adjacent pleat tips (34), applying a continuous strand of adhesive (32) to the web, and adjusting the arrangement of the plurality of pleats (24) into a second spaced configuration defined by a second distance between adjacent pleat tips (34). The web has a front face (36) and a rear face. Each fold line is intermediate oppositely sloping first and second wall surfaces (35). The plurality of fold lines form a plurality of pleats (24) having a first plurality of pleat tips(34) and a second plurality of pleat valleys (46). The second distance is different from the first distance.

摘要： A flat fold filtering face piece respirator 10 that includes a mask body 12 and a harness 14. The mask body 12 includes a filtering structure 16 that contains a cover web 48, 50 and a filtration layer 52 that contains electrically-charged microfibers. The filtering structure 16 is folded over upon itself in a nose region 32 of the mask body 12 to be at least 1 centimeter or more wide and to extend across the upper perimeter of the mask body in a generally straight line when the respirator is in the folded condition. The filtering structure 16 has a deflection greater than about 0.5 millimeters and has a recoverability of at least 40% in the folded condition. A mask body having this construction is beneficial in that it does not need to use a nose foam to obtain a snug fit over the nose.

摘要： A filtering face-piece respirator (10) that includes a harness (14) and a mask body (12) that has a multi-layer filtering structure (16). Present at the perimeter (24) on the interior surface of the mask body (12) is a region having an increased coefficient of friction (44), in relation to the filtering structure (16). This region (44) can be formed by a discontinuous coating of a polymeric material. The region (44) improves the fit of the respirator (10) on the wearer's face, providing a non-slip seal, yet allows moisture laden air to exit from the interior gas space of the mask body (12).
