<P>PROBLEM TO BE SOLVED: To improve absorption volume and absorption rate of a mask, as a virus capturing filter of a conventional mask leaks viruses and smells because floating substances easily carried by wind currents pass through sphere aggregate, while double layered resin uses frankincense on the surface, which is hard to be infiltrated into wood, on the surface and thus adhering particles are hardly penetrated into. <P>SOLUTION: A saclike filtration filter 1 made of nonwoven fabric for the mask for work is placed in front of a capture portion (sphere aggregate) 4 for filtering exhalation. The outside of the frankincense on the sphere surfaces is further covered by Siam Benzoin, so as to form three layers. <P>COPYRIGHT: (C)2012,JPO&INPIT |
