Abstract
A mask has to possess sufficient electrostatic charges in order to maintain a filtering effect of the mask using static electricity. However, an electrostatic property naturally decreases as an amount of the electrostatic charges decreases when contacting a human body or exposed to the air. Resultantly, as an initial electrostatic filtering effect gradually decreases, an initially intended function of the mask is not implemented.
