ABSTRACT:
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.
