Abstract

The durability and performance of air purification filters are typically improved through post processing. Post processing of air purification filters is mainly performed using the dipping process, which causes problems such as deformation of the filter media and decreased uniformity because of the increasing tension and mass of the filter media. To resolve these problems, we devised a tension-free post processing method and compared its performance with that of the dipping process. In our method, a resin tube is placed horizontally above a mangle roller, enabling resin to flow down the mangle roller, allowing it to be easily absorbed by the filter media. Owing to the horizontal placement of the resin tube, the tension applied to the filter media can be minimized. The basic physical performance such as tensile strength and initial pressure drop, of the filter media produced using our method improved evidently. Intensive research and development of the postprocessing technique are required to further improve the overall efficiency and durability of air purification filters.
