Abstract

PURPOSE: To obtain a nonwoven fabric laminate for electret formation, having ready handleability, capable of providing an electret body having excellent air permeability, collection efficiency and high dust retention, by sticking fast specific two kinds of nonwoven fabric mats, laminating and carrying out electret formation. CONSTITUTION: A nonwoven fabric mat comprising uniformly dispersed fibers (preferably polypropylene fibers, etc.), having <=4 μm, preferably 0.5-3.0 μm average fiber diameter, having 0.02-0.3 g/cm<3> , preferably 0.06-0.24 g/cm<3> density is stuck fast to and laminated to a nonwoven fabric mat comprising uniformly dispersed polyolefin fibers (preferably polypropylene fibers, etc.), having as >=8 μm, preferably 9-50 μm average fiber diameter, having 10 cc/cm<2> /sec, preferably 15-250 cc/cm<2> /sec air permeability to give the objective nonwoven fabric laminate for electret formation.
