Abstract
The present invention relates to a method of utilizing the aerodynamic interlacing process to produce a chemical filter media, comprising: (a) utilizing the airflow to bring short-cut fibers and functional particulates to a composite air blower, thereby enabling the blowing air of the short-cut fibers and the functional particulates to enter into diffusing mixing conveying area at the same time so that the mixed airflow diffuses the short-cut fibers and the functional particulates from the top to the bottom which flow afterwards to a multilayer interlacing forming area beneath; (b) utilizing an air suction device under the multilayer interlacing forming area to adsorb the short-cut fibers and the functional particulates for sequentially piling up on a moving forming matrix so that the filter media is formed with a laminated structure having several layers of from sparse to dense, (c) heating the filter media and (d) cooling the filter media.
