The disclosure is of a method of making air filter fabrics from non-woven, thermoplastic, synthetic polymeric resin, staple textile fibers and of the fabrics so made. The method comprises providing a non-woven web of the fibers, coating the fibers with a fiber stabilizing agent, pressing the fibers together so as to rupture the film at cross-over points and fusing the fibers together at the sites of the ruptured film. The product filter fabrics are characterized by controlled high permeability, strength, wear resistance, dimensional stability, lint free surfaces and advantageous particle release properties.
