AIR FILTER MATERIAL USING MULTILAYER ELECTRET NONWOVEN FABRIC |
摘要 |
<p>Present invention provides an air filter material using a laminated electret nonwoven fabric subjected to electret processing in which one layer or a plurality of layers of nonwoven fabrics (referred to as nonwoven fabric B) including fibers having a mean fiber diameter in the range of 10 micrometers to 100 micrometers and being larger than a mean fiber diameter of fibers constituting nonwoven fabric A are laminated on at least one side of a nonwoven fabric (referred to as nonwoven fabric A) obtained by mixing two kinds of fibers having a mean fiber diameter in the range of 0.1 micrometer to 15 micrometers and having a different melting point (fibers having a lower melting point are defined as fibers D and fibers having a higher melting point are defined as fibers E), and a laminated electret filter material having a low pressure loss and a high collection efficiency. The filter material is suitably used for a medical mask, an industrial mask, a general purpose mask or the like.</p> |
