摘要
The present invention and relates to a method non-woven fabric-type nano-membrane folds back filter manufactured using a heat-resistant polyimide fibers, and the fiber preparation step of preparing the polyimide fiber and more particularly, wherein the polyimide fibers prepared via the fiber preparation step non-woven fabric formation step of forming a non-woven fabric in the, and wrinkle formation step of the non-woven fabric-forming step to form a bag filter element which living quarters to form a wrinkle in the produced non-woven fabric, the bag filter by cutting the coarse bag filter member to the crimping stage It made up of processing to form, removing the fine dust more than 99.9%, a heat-resistant dust-collecting filter media available in the high temperature (above 200), durability, and has acid resistance. To a weak poly-imide fibers acid acid-resistant, and to have the durability by the heat resistance (acid resistance) foam processing, to form a non-woven fabric into a polyimide fibers during the formation of the nonwoven fabric is sikimeuroseo formed by applying a water flow T rakbeop and form wrinkles , it has had a high heat resistance has the effect of improving the filter efficiency by the addition wrinkles soon as possible to form a high density, lightweight non-woven fabric. ;
