Zusammenfassung:PURPOSE: Provided is a spun-bonded cartridge filter for treating water, which is produced from a thermoplastic resin and elvan, and has a multifunction such as porous property, adsorption of heavy metal, and ion exchange. CONSTITUTION: The spun-bonded multifunctional cartridge filter having a fill density of 0.1-0.7 and a pore size of 0.5-200 μm is produced by melting 60-99 wt% of the thermoplastic resin such as high density polyethylene, polypropylene, and polyester and 1-40 wt% of the elvan at 150-270 °C, and then performing spray-spun extrusion of the molten mixture onto a fine fiber by using a multi-nozzle head at 300-450 °C.
