Vacuum Cleaner Bag
Conventional vacuum cleaner bags are usually made of a nonwoven layer that cannot
prevent dust particles passing through the bag into the air. The released dust particles
in the air can penetrate bronchi and lungs and pose a severe health threat. Therefore,
new classes of vacuum cleaner bags which have electrospun nanofibers laminated between
their layers are very useful for filtering the pollutants released from vacuum cleaner
bags. Nanofiber layer in vacuum cleaner bag must be laminated by two nonwoven layers
as protective layers which is shown in the image below.
