Development of meltblown non-woven fabric type non-magnetic noise suppressor

Abstract

This paper systematically discusses fabrication process, morphological observation and electromagnetic noise suppression performance of new series of the non-woven fabric type noise suppressor consisting only of the meltblown thin fibers. Effect of contact resistance has been clarified experimentally for the first time as the sheet resistance becomes the less and accordingly the loss ration becomes higher as the pressure during fabrication increases, and as the heat treatment is applied to weld the fibers. The noise suppression performance was as high as conventional thick-thin fiber type NSS.
