POSITIVE ELECTRIC CHARGE-MEDIA CONTAINING MULTI-LAMINATING STRUCTURE AND THE PREPARING METHOD THEREOF

摘要

The present invention relates to a positively charged media including a laminated structure. The present invention further relates to a production method thereof. More specifically, the present invention relates to a positively charged media including a laminated structure and a production method thereof. According to the present invention, the positively charged media is produced by coating one side of a non-woven fiber with a coating agent asymmetrically containing cations, thereby having a high surface charge and fine pores. Thus, the positively charged media is capable of adsorbing and eliminating virus which is electrically anionic as well as physically removing foreign substances.
