Description

Sheet paper with air purification function {SHEET WITH AIR PURIFICATION FUNCTION}

The present invention relates to sheet paper having an air purification function, and more particularly, to sheet paper having an air purification function capable of purifying air by removing volatile organic compounds and odors in the air.

The environment we live in is polluted with volatile organic compounds (VOCs; hereinafter referred to as 'VOCs') and various bacteria and fungi.

The volatile organic compounds (VOCs) include benzene, toluene, xylene, etc., which are highly toxic and can cause mutations and cancer even in very small amounts.

In particular, benzene is a carcinogen and a substance that causes leukemia and lymphoma. Toluene and xylene are known to cause damage to the kidneys and liver as well as brain dysfunction when habitually inhaled (MOBachmann and JE). Myers, Soc Sci Med 40, 245, 1995) Environmentally friendly regulations on these substances these days are in the case of the United States and Japan, the "Pollutant Release and Transfer Register (PRTR)" system is implemented to discharge, transfer, and register environmental pollutants in their country. In the European Union, it is managed through the REACH system, which has been applied since 2004, and in Korea, volatile organic compounds are managed through related laws and regulations. Countermeasures against this are still insufficient.

In addition, air pollution caused by bacteria and mold causes a lot of discomfort by generating bad odors from clothes and interior products that are frequently used in real life.
