Abstract

An air filter in which a thick sheet of textile of three-dimensionally knitted synthetic fiber thread is sliced at a middle position in a thickness direction and separated into a front face and a rear face. The front face or the rear face is one face side, and many short fibers are protruding from another face side. Further, the air filter is electrified as a whole.

Description

Technical field [0001] The present invention relates to an air filter and a manufacturing method thereof. The air filter is used to clean air for household or commercial electrical equipment that requires air circulation. Background technique [0002] As shown in FIG. 12, the conventional air filter has a corrugated honeycomb structure, in which a circular-wave first member 26 and a flat second member 27 are sequentially layered (stacked) to be received in a direction perpendicular to the surface of the filter The airflow, thereby collecting dust and deodorizing. And, as shown in FIG. 13, another conventional filter is composed of a pleated filter 28 and a plate-shaped filter 29. The pleated filter 28 is sequentially formed with a convex part and a concave part (cross section), The plate filter 29 is used to maintain the configuration of the filter 28 to receive the air flow in the direction of the arrow C. [0003] However, the conventional air filter requires more labor in manu...
