METHOD OF MANUFACTURING NONWOVEN ELECTRET FABRIC USING NANOWEB

摘要

PURPOSE: A method for fabricating a non-woven electret fabric using nano web is provided to improve or maintain dust collection efficiency. CONSTITUTION: A method for fabricating a non-woven electrets fabric comprises: a step of preparing non-woven fabric laminate in which melt blown nano web(7) and melt blown non-woven fabric(6,8) formed of non-conducting thermoplastic fibers; a step of passing the non-woven fabric laminate through water of 100-350 bar and discharging the non-woven fabric laminate; a step of drying charged non-woven fabric laminate; and a step of discharging the non-woven fabric laminate.
