| Abstract: | The filtration behaviour of two types of spun-laid nonwoven fabrics, namely
thermobonded and needle-punched, with wide range of physical parameters has
been studied. A computerized air filtration apparatus has been designed and
developed for measuring the air filtration characteristics of different types
of filter fabrics. The developed apparatus measures the filtration parameters
following the principle of dry filtration mechanisms. Needle-punched
nonwovens show good filtration efficiency with lower pressure drop than the
corresponding thermobonded nonwovens. Overall, the needle-punched fabrics
perform better as a filter fabric in comparison to thermobonded nonwovens |
