Abstract
A method for manufacturing an electrostatic non-woven intake filter, may include a fabric preparation process that weaves at least a kind of fiber fabric into a web, and a filter fabric manufacturing process that weaves the web into a felt that has at least a layer, and manufactures an electrostatic non-woven intake filter material that is a non-woven fabric having a fiber tissue having a semipermanent electrostatic force by allowing a binder and an electrostatic material to permeate the felt.
