Sanitary napkins or M-napkins.

Also known as sanitary napkin: aunt napkin, M napkin.

The main materials of sanitary napkins are polymers and polymer composite papers formed from cotton, non-woven fabrics, paper pulp or composites of the above materials. The side design is mainly used to prevent side leakage, because When used, it will be at an angle with the sanitary napkin body, making it easier to rub against the groin area. Therefore, sanitary napkins with soft material on the side are more popular among women.

Sanitary napkins are divided into three layers, namely the top layer, absorbent core and bottom layer. The backing glue of sanitary napkins is an impermeable material that can retain menstrual blood in the sanitary napkin and is used to absorb the menstrual blood that flows out of the vagina when women have menstruation.

Misunderstandings about using sanitary napkins:

1. If you use sanitary napkins with strong absorption and good protective functions, you think that they will not last long after being used for a long time. A sanitary napkin doesn't matter either.

2. Forget to change when menstrual blood volume is low. There is a survey: Japanese women change their breasts an average of 6 times a day during menstruation, while Chinese women change them 3 times a day. As Asians, there shouldn't be much difference in their physiques. However, because a high proportion of Chinese women use intrauterine devices, their overall menstrual flow should be greater.

When using sanitary napkins, remember:

1. Change them every two hours.

2. Use medicated sanitary napkins with caution to prevent allergies.

3. Wash your hands before opening sanitary napkins.
