摘要： Reinforced filter media are prepared by adhering discrete, non-intersecting strands of thermoplastic or thermoset materials to the filter media web. The filter media may be a fabric, a nonwoven web or a filtering foam. The reinforced filter media can be used to prepare respirators, including flat-fold respirators or molded respirators.

摘要： A flat-fold respirator is made from a stiff filtration panel joined to the remainder of the respirator through at least one line of demarcation. The panel contains a porous monocomponent monolayer nonwoven web that contains charged intermingled continuous monocomponent polymeric fibers of the same polymeric composition and that has sufficient basis weight or inter-fiber bonding so that the web exhibits a Gurley Stiffness greater than 200 mg and the respirator exhibits less than 20 mm H2O pressure drop. The respirator may be formed without requiring additional stiffening layers, bicomponent fibers, or other reinforcement and can be flat-folded for storage. Scrap from the manufacturing process may be recycled to make additional stiff filtration panel web.

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.

摘要： Shaped filtration articles are made from a monocomponent nonwoven web formed by flowing first and second fiber-forming materials of the same polymeric composition through first and second die cavities in respective fluid communication with first and second sets of orifices in a meltblowing die tip. The first fiber-forming material flows at a lesser flow rate or viscosity through the first die cavity and first set of orifices to form a set of smaller size filaments and the second fiber-forming material flows at a greater flow rate or viscosity through the second die cavity and second set of orifices to form a set of larger size filaments. The collected nonwoven web contains a meltblown bimodal mass fraction/fiber size mixture of intermingled continuous microfibers and larger size fibers of the same polymeric composition.

摘要： A molded respirator is made from a monocomponent monolayer nonwoven web of continuous charged monocomponent meltspun partially crystalline and partially amorphous oriented fibers of the same polymeric composition that have been bonded to form a coherent and handleable web which further may be softened while retaining orientation and fiber structure. The respirator is a cup-shaped porous monocomponent monolayer matrix whose matrix fibers are bonded to one another at least some points of fiber intersection. The matrix has a King Stiffness greater than 1 N. The respirator may be formed without requiring stiffening layers, bicomponent fibers, or other reinforcement in the filter media layer.
