MULTI-LAYER NON WOVEN FABRIC FOR GAS FILTRATION

摘要

PURPOSE: A multi-layer non woven fabric for gas filtration is provided, which can be easily bent-up by using only non-woven fabric without using plastic net or metal net so that can save production cost and solve the problems of increasing resistance of filter caused by plugging of non-woven fabric where plastic net or metal net contact with the fabric. CONSTITUTION: The multi-layer non-woven fabric is manufactured by laminating (i) No.1 non-woven fabric prepared by at least 70-0 wt.% of a raw material that is selected from a group consists of chemical resin film slitting fiber, a fiber charged with static electricity, polyester fiber, polypropylene fiber, nylon fiber and acrylic fiber; and (ii) at least one non woven fabric that is selected from a group consists of No.2 non woven fabric, No.3 non woven fabric and melt blown non woven fabric.
