However, people cannot wash hands in time in daily life, particularly in outdoor activities, which is harmful to the health of people to a certain extent, so that the demand and the day of the wet tissue are greatly increased. Particularly, in recent two years, the production and market development of the wet tissue are very rapid, the use of the wet tissue is diversified day by day, and the wet tissue becomes a new favorite in the market of the toilet paper. The wet tissue is a tissue for wiping face and hands or skin made of pure water, spunlace nonwoven fabric and propylene glycol.
