摘要

"Eletreto fibers composed of a polymeric material and an additive fluoroquu00ecmico, non woven braid, respirator, and.The processes of filtration of particulate matter from a gas containing aerosol partu00ecculas, making eletreto fibres, and prediction of the performance of a filter fabric eletreto ".Eletreto fibers containing a polymeric raw material and an additive fluoroquu00edmico. The eletreto fibers have a low level of extractable hydrocarbon material.Eletreto filters which have low levels of extractable hydrocarbon show enhanced filtration performance.
