1)Acrylic dust bag possesses large porosity, good permeability and anti-chemical property. 2)Its surface is neat and smooth

1)Acrylic dust bag is produced by needling craft, made of acrylic fiber of staggered arrangement and gap uniform distribution.

2)Its surface is neat and smooth processed through heat setting and singeing, so it cannot be stemmed by dust easily.

3)possesses large porosity, good permeability and anti-chemical property.

4)takes effect in conditions of middle temperature and environment filling acid and alkali gas.
