摘要： A molded respirator and method of making are disclosed, wherein the molded respirator is made from a porous nonwoven web containing meltblown fibers and staple fibers. The meltblown fibers may be present as a bimodal mixture of microfibers and mesofibers, and comprise an intermingled mixture with staple fibers further intermingled therein. The molded respirator may also contain at least one secondary filtration layer.

摘要： A filter element that comprises a porous molded web 10′ that contains thermally bonded staple fibers 12 and non-thermally bonded electrically charged microfibers 14. The molded web is retained in its molded configuration, at least in part, by bonds between the staple fibers 12 at points of fiber intersection 13. The web may be molded, for example, into the shape of filtering face mask 16.

摘要： Respirator 10 has a respirator body 11 that is configured to fit over the nose and mouth of a wearer. A thermochromic material 18 is positioned on the respirator body 11 such that the thermochromic material 18 makes thermal contact with the wearer's face when the respirator 10 is worn. The contact causes the thermochromic material 18 to change color to allow the wearer to determine if a proper fit has been established.
摘要翻译： 呼吸器10具有配置成配合穿戴者的鼻子和嘴部的呼吸器主体11。 热变色材料18定位在呼吸器主体11上，使得当呼吸器10磨损时，热变色材料18与穿着者的脸部发生热接触。 接触导致热变色材料18改变颜色，以允许穿戴者确定是否已建立适当的配合。

摘要： Molded respirators containing an air-permeable, sorbent-particle-containing layer between air-permeable particle-retaining layers. The particle-containing layer is stretchable during shaping without tearing or significant loss of particles. At least some of the fibers in the particle-containing layer are sufficiently tacky after being formed by themselves into a particle-free web and cooled to room temperature so that the web will adhere to itself. The respirators can be molded from flat webs without the need to fabricate the particle-containing layer into a shaped preform.
摘要翻译： 在透气性颗粒保持层之间含有透气性的含有吸附剂颗粒的层的模制呼吸器。 含颗粒层在成型过程中是可拉伸的，不会撕裂或显着损失颗粒。 含颗粒层中的至少一些纤维在其自身形成无颗粒的纤维网并冷却至室温后具有足够的粘性，使得纤维网将粘附到其自身上。 呼吸器可以由扁平网片模制而不需要将含有颗粒的层制造成成型的预制件。
