Friction-charged filter material |
摘要 |
The invention provides a charged filter material composed of a combination of polyester fiber and polyolefin fiber, which can exhibit high particle collection efficiency with low pressure loss, and further provides a charged filter material which is self-extinguishing in the combustibility classification according to JIS D 1201 (1977) "method of combustibility test for organic materials disposed in automobile compartment" and which does not generate dioxins at the time of incineration. Disclosed is a friction-charged filter material comprising at least 20 mass % of polyester fiber containing a phosphinic acid compound and/or sulfonic acid compound and at least 30 mass % of polyolefin fiber, as well as the above-described friction-charged filter material wherein the polyester fiber comprises a phosphinic acid compound and/or sulfonic acid compound copolymerized with a polyester molecular chain.
