AIR FILTER HAVING METAL-SPATTERED SURFACE AND REGENERABLE BY WASHING

摘要

PROBLEM TO BE SOLVED: To provide an air filter regenerable by washing which can be repeatedly washed and used by subjecting metal sputtering to the surface of non-woven cloth with metal. SOLUTION: In the air filter regenerable by washing, the surface is subjected to metal sputtering, thereby, a filter pressure loss is easily recovered, the recycling use is permitted and the durability is maintained even after cleaning because metal sputtering fibers are used. Further, when a nonwoven fabric subjected to metal sputtering and a nonwoven fabric not subjected to metal sputtering are laminated, the nonwoven fabric subjected to metal sputtering functions as a prefilter, prevents the fouling of the nonwoven not subjected to metal sputtering and can prolong the life.
