发明名称 MOLDED RESPIRATOR HAVING OUTER COVER WEB JOINED TO MESH
摘要 A respirator 10 that has a mask body 12 and a harness 14 that is attached to the mask body 12. The mask body 12 includes a filtering structure 18 that has an inner cover web 40a, an outer cover web 40b that comprises melt-blown fibers and staple fibers, and a filtration layer 42 that is located between the inner and outer cover webs 40a, 40b. The mask body 12 also has a mesh 20 that is joined to the outer cover web 40b. A respirator having this construction is more resistant to inward collapse of the filter media during breathing and is more aesthetically pleasing.
