Abstract

The invention discloses a compound filter membrane as well as a processing device and method thereof. The compound filter membrane is prepared by hot pressing multiple layers of ES fiber spun-bonded non-woven fabrics. According to the compound filter membrane as well as processing device and method thereof disclosed by the invention, as the characteristic of low cortical tissue melting point of a bi-component skin-core structure of ES fibers are fully utilized, in the premise without using an external adhesive, compounding of the non-woven fabrics can be achieved by utilizing hot-pressing adhesion of the fibers with one another due to self fiber melting; by carrying out permutation and combination and a hot-pressing adhesion process on the non-woven fabrics with different filtering accuracies, the compound filter membrane is accurate and uniform in controlling the filtering accuracy, large in pollutant holding quantity, high in filter flux and long in service life, and the using cost of a user is lowered.

Description

technical field [0001] The invention relates to a filter material, in particular to a composite filter membrane with high dirt-holding capacity and a processing device and method for the composite filter membrane. Background technique [0002] At present, the industrial fluid filtration filter material generally adopts metal powder sintering, natural or synthetic fiber wool sticky, non-woven fabric, fiber paper, etc., among which the non-woven fabric has excellent filtration characteristics, consistent filter hole precision and easy processing and filtration. The capacity is controllable and becomes an ideal material for high-precision filter media. For example, the Chinese utility model patent with the authorized publication number CN2224016Y and the name of multi-layer melt-blown composite filter material discloses a multi-layer melt-blown composite filter material. Spray-blown non-woven fabric is used as the core material, and spun-bonded fabric is used as the surface lay...
