摘要：Elastomeric nonwoven fibrous fluid filter media for removal of particulatecontaminants from the fluid are provided. The filter media comprises thermoplasticelastomeric melt-blown small diameter fibers, the small diameter fibers being randomlyarrayed, the filter media having substantially uniform stretch properties in all directionsand whose filtration properties are independent of filter media elongations sufficient toincrease the filter media surface area at least aout 10 percent. The filter media isparticularly useful as a prefilter on respirators.
