摘要： Various embodiments of a respirator that includes a harness, a mask body, and an exhalation valve are disclosed. The exhalation valve can include a valve seat and a flexible flap that is in engagement with the valve seat. The flexible flap can have one or more materials that can cause the flap to flash when moving from a closed position to an open position or vice versa. The flashing valve can make it easier for a user to ascertain whether the valve is operating properly.

摘要： A filtering face mask that includes a mask body that is adapted to fit at least over the nose and mouth of a wearer to create an interior gas space when worn; and an exhalation valve that is in fluid communication with the interior gas space. The exhalation valve includes a valve seat with a seal surface and an orifice through which exhaled air may pass to leave the interior gas space; and a flexible flap that is mounted to the valve seat such that the flap makes contact with the seal surface when the valve is in its closed position and such that the flap can flex away from the seal surface during an exhalation to allow exhaled air to pass through the orifice. The flap is unbiased when in its closed position and exhibits a cantilever bend ratio of 0.0050 or less.
摘要翻译：一种过滤面罩，其包括面罩主体，所述面罩主体适于至少装配在穿戴者的鼻子和嘴部之上，以在佩戴时产生内部气体空间; 以及与内部气体空间流体连通的呼气阀。呼气阀包括具有密封表面的阀座和呼出的空气可通过的孔口以离开内部气体空间; 以及安装到阀座的柔性翼片，使得当阀处于其关闭位置时，翼片与密封表面接触，并且使得在呼气期间翼片可以从密封表面弯曲以允许呼出的空气通过通过孔口。当其处于关闭位置时，该挡片是无偏的，并且悬臂弯曲比为0.0050或更小。

摘要： A method of making an auxetic mesh, which method includes: (a) extruding a polymeric material (60) onto an open casting surface (58) that has an intended pattern (62) disposed therein, the pattern (62) being configured to create an auxetic mesh ((20); (b) wiping off excess extruded polymeric material (60) from the open casting surface (64); (c) removing the cast mesh (20) from the open casting surface (64) after the excess polymeric material (60) has been wiped off; and (d) removing any residual polymeric material that is not of the intended mesh pattern (20). The method allows for the continuous production of auxetic meshes.

摘要： A filtering face-piece respirator 10 that has a harness 14 and a mask body 12. The mask body 12 includes a support structure 16 and a filtering structure 18. The support structure 16 contains an auxetic mesh 20 that has been molded into an intended cup-shape configuration, and the filtering structure 18 contains a filtration layer 42 for removing contaminants from the ambient air. The use of an auxetic mesh 20 in the support structure 16 provides more uniformly-sized openings 26 in the mesh 20 and reduces opportunities for mesh overlapping and mesh distortion.

摘要： A filtering face-piece respirator 10 that includes a mask body 12 and a harness 14. The mask body 12 contains a filtering structure 18 that is retained in position on the mask body 12 by a support structure 16 that includes a longitudinally-movable, centrally-spaced, transversely-extending member 26 that extends from a first side 22 of the structure 16 to a second side 24 without being joined together by any longitudinally-extending members that hinder movement of the transversely extending member 26 in the longitudinal direction. The transversely-extending members converge towards each other at east side 22, 24 of the mask body 12. A filtering face-piece respirator 10 of this construction can allow the mask body 12 to readily accommodate the motion of a person's jaw. Workers who use this filtering face-piece respirator may find it much easier to talk to other persons when working. A single mask size also may be able to properly fit to faces of various sizes.
摘要翻译：包括面罩主体12和线束14的过滤面件呼吸器10.面罩主体12包含过滤结构18，其通过支撑结构16保持在面罩主体12上的适当位置，支撑结构16包括纵向可移动的中心横向延伸的构件26，其从结构16的第一侧面22延伸到第二侧面24，而不被阻碍横向延伸构件26在纵向方向上的运动的任何纵向延伸的构件接合在一起。横向延伸构件在面罩主体12的东侧22,24处朝向彼此会聚。具有这种结构的过滤面罩呼吸器10可以允许面罩主体12容易地容纳人的颚的运动。使用这种过滤式面罩式呼吸器的工作人员在工作时可能会更容易与其他人交谈。单一的面罩尺寸也可以适当地适合各种尺寸的面部。

摘要： Articles comprise: a nonwoven fiber web and one or more strips bonded to the nonwoven fiber web. The strips comprise a shape-memory polymer that has a strained temporary shape and an intrinsic shape. If heated at or above a transition temperature, the strip at least partially converts from the strained temporary shape to the intrinsic shape, thereby causing at least one of folding, cupping, or puckering of the nonwoven fiber web. Methods of heating the articles to provide folded, cupped, and/or puckered articles are also disclosed.
