Toilet paper was introduced to China during the Republic of China, but because people were generally poor at that time, only those families with extremely rich countries dared to use it.

Before paper appeared and was cheap enough to be wiped, toilet cleaning materials used by people included water, cloth, leaves, corncob, sawdust and bamboo chips (toilet fragments) and clods.

The earliest record of using paper to wipe filth in China was found in the Southern and Northern Dynasties. In the third year of Yuan history, Yuan's wife was extremely filial to her in-laws, and waited on her mother-in-law, Queen Zhao Ruishun (Queen Chayu). "The toilet paper never leaves her hand, and she has to wipe her face to make it soft."

Identify the quality of toilet paper:

1, some toilet paper feels thick, and this kind of paper is of low grade. Because, under the same weight, there are fewer sheets of thick paper. For example, there are more than 270 sheets of D-grade paper per 500 grams, while there are less than 250 sheets of E-grade paper. So in the case of the same weight, choose a whole package of thinner toilet paper.

2. Because toilet paper is sold by weight, individual manufacturers will add more fillers in the production process. The paper produced in this way is thick and hard, which is harmful to human body. So choose soft toilet paper when you buy it.

3. The whole process of toilet paper production is completed at high temperature. If the packaging is not timely, incomplete or stored improperly, the paper will be contaminated by moisture. Therefore, when choosing, we must choose those products that are well packaged and have close production dates.

4. Pay attention to the industry standard of the Ministry of Light Industry (QB2500-2000), which divides wrinkled toilet paper into two types: small roll paper and knife-cut paper, and the technical indicators are divided into five grades: A, B, C, D and E. ..
