Abstract
PURPOSE: To obtain a high-performance air filter capable of incinerating a used filter medium by a method wherein a pluality of webs consisting mainly of extra fine combustible synthetic fibers are integrated by pressing under heating.
CONSTITUTION: A plurality of webs whose weight per square meter is 10W150g/ m2, consisting mainly of the extra fine combustible synthetic resins of 0.1W2 microns in fiber diameter are laminated and integrated to form a fibrous laminate. The laminate has a porosity of 75W95% and an initial resistance to gas permeation of not higher than 30mmH2O (air velocity 3cm/mm).
