Is rice soup used for paper sizing? How to operate specifically?

Bed sheets are sized with rice soup. Cook some porridge first, put twice as much water as usual, pour the cooked rice soup into the basin, put the sheets into the rice soup after washing, and paste the rice soup evenly on the sheets with chopsticks, spoons and other tools. After the rice soup is cold, rinse the sheets with clear water, and then squeeze out the excess water by hand. Rice soup is generally boiled porridge and cooked rice soup with plenty of water.

Sizing sheets, I remember it was the habit of old people in my grandmother's time. It will look very flat and elegant, but it will make the clothes uncomfortable and harmful to the body.

Usually people can accept the harm of chemical raw materials to human body, so why is the rice soup that they drink almost every day harmful to human body? In fact, rice soup is harmless, which is the first thing to be sure.

But after the clothes were starched with rice soup, the holes in the cloth were blocked and the clothes became airtight. It will feel sultry when it is hot in summer, and hard and cold in winter, which is very uncomfortable. The same is true of sheets. After sizing, it is airtight and not soft, which will also make people feel very uncomfortable.

In addition, because the cloth is made of rice soup pulp, it is easy to be moldy and moth-eaten, and wearing it again will cause skin diseases. Therefore, rice soup slurry is not suitable for making clothes or sheets.
