Do you know how sanitary napkins are produced?

Sanitary napkins are a close companion for women throughout their lives. We never seem to know how sanitary napkins are produced. Is a thin and white sanitary napkin really as simple as a pile of cotton? Xingshi will tell you today!
The experience with sanitary napkins is far from as simple as we imagine. White is not only cotton, but also non-woven fabrics, pulp, absorbent polymer materials, and many other materials. In the production process, raw materials should be installed in machine mixing, sorting, and wheel molding, and then through machine transfer, indentation cutting of edges, compression of inner layers and other processes, followed by compression sealing film, separation, folding packaging, thermal sealing, and the birth of sanitary napkins.
Do you think it's over now? Not yet. In the production process of sanitary napkins, repeated tests such as stain detection, calibration and positioning, and metal detection must be carried out. In addition, there are many performance indicators tested for sanitary napkins before, during, and after production, which can eventually leave the machine and enter the market. Behind seemingly simple things, there are often countless people's sweat hidden.
