AIR FILTRATION WITH FINE POLYMERIC FIBRES

摘要

The need for higher filtration efficiencies without adversely affecting the filter lifetime is growing.Fibre diameter is one of the controlling factors in achieving Wgh particulate efficiencies.The most common fibrous raw material which has commercially available fibres with sub-micron diameters is microglass fibre.In recent years,we have seen renewed interest in other manufacturing processes which are capable of manufacturing polymeric fibres with sub-micron diameters.As a result,more tools for the filtration expert to approach their specific problem are becoming available.This paper will take a pragmatic approach to the enhancement of filtration media performance by fine polymeric fibres.Results show a significant impact of these polymeric fine fibres on filtration performance.
