摘要: A molded respirator is made from a monocomponent monolayer nonwoven web containing bimodal mass fraction/fiber size mixture of intermingled continuous polymeric microfibers and larger fibers the same composition. The cup-shaped porous matrix whose are bonded to one another at least some points fiber intersection. has King Stiffness greater than 1 N. may be formed without requiring stiffening layers, bicomponent fibers, or other reinforcement in filter media layer.
