Who invented sanitary napkins?

During World War I, French nurses observed that cellulose materials used to bandage wounds could absorb menstrual blood better than cloth strips. The invention of "cellulose cotton" was used in disposable bandages and related products. Inspired by this, nurses made their own "disposable sanitary napkins" using cotton or cloth wrapped in cheese. Modern sanitary napkins were born.

Sanitary napkins are a type of sanitary product used by women during menstruation. The main materials are cotton, non-woven fabrics, pulp, or polymers and polymer composite paper formed by composites of the above materials.

Sanitary napkins on the market are divided into three categories according to their materials: dry mesh sanitary napkins, cotton soft sanitary napkins and pure cotton sanitary napkins.

Other common menstrual products include tampons, menstrual cups, panty liners, etc. When choosing sanitary napkins, you should pay attention to the material composition, hygiene standards and your actual situation.

What kind of garbage do sanitary napkins and diapers belong to?

Sanitary napkins and diapers are classified as dry garbage, and most of their materials cannot be degraded by themselves, which is in line with the nature of dry garbage. Sanitary napkins, diapers and other dry garbage are generally disposed of in sanitary landfills, while wet garbage will be reclassified and refined into resources such as feed and organic fertilizer.

Sanitary napkins and diapers are classified as dry garbage because their main material is inorganic cotton, which cannot be degraded. Although the high-molecular water-absorbent resin inside can be degraded, most of the ingredients inside cannot be degraded, which is consistent with the nature of dry garbage.

The opposite of dry garbage is wet garbage. The definition of wet garbage is household waste that is easy to rot, deteriorate and can decompose naturally. Common wet garbage in life includes melon peels and fruit shells, leftovers, expired food, flowers and plants, leaves and weeds.

Wet garbage and dry garbage have different properties and are treated differently. Sanitary napkins, diapers and other dry garbage are mainly treated by sanitary landfill or incineration, while wet garbage is usually sorted again and extracted to make organic fertilizer, feed or other resources.

Can expired sanitary napkins be used if they are not opened?

Expired sanitary napkins cannot be used if they are not opened, because higher hygiene standards are set when manufacturing sanitary napkins, and expired sanitary napkins will not be able to meet these standards. The shelf life of sanitary napkins is generally around 3 years, but those that have been opened can only be kept for 2 months. In addition, sanitary napkins should be stored separately and never placed in the bathroom.

Expired sanitary napkins cannot be used if they are not opened. Sanitary napkins have a strict set of production standards, and expired sanitary napkins may have bred a large number of bacteria or harmful substances. If you continue to use them, it may have a certain impact on human hygiene.

2. Save time

Sanitary napkins can be stored for up to 3 years, but once opened, they may be exposed to the air, thus providing conditions for the growth of bacteria. Therefore, sanitary napkins should be used as soon as possible after opening, and no more than 2 months at most, so as not to affect normal use.

3. Notes

Sanitary napkins should be stored in a dry and ventilated environment and should be individually packaged to avoid contact with other objects and infection from bacteria and harmful substances. Do not place sanitary napkins directly in the bathroom for convenience, as this can easily cause the sanitary napkins to mold.
