Introduction
Sanitary pads are one of the most commonly used menstrual products worldwide. They help keep women and girls comfortable and confident throughout their menstrual cycle. Pads are designed to absorb menstrual blood and prevent leakage, thus protecting clothing and bedding from stains. While pads have been in use for decades, many are still curious about how they work. In this article, we will discuss in detail how pads work.
The anatomy of a pad
Before we delve into how pads work, it is essential to understand their anatomy. A typical sanitary pad consists of four layers, each playing a specific role in ensuring that the user stays comfortable and dry.
The first layer is the top cover, which is in contact with the skin. It is made from a soft and absorbent material such as cotton. The cover’s primary function is to keep the user comfortable by providing a soft and smooth surface that does not irritate the skin.
The second layer is the absorbent core, which is responsible for soaking up menstrual blood. The absorbent core can be made from a blend of materials, such as cellulose, synthetic fibers, and superabsorbent particles. The absorbent core’s structure varies between brands, with some being thicker and more absorbent than others.
The third layer is a waterproof barrier that prevents leakage. It is made from a polyethylene film, which is a highly water-resistant material. The barrier is usually located between the absorbent core and the bottom layer, which is in contact with the user’s underwear.
The final layer is the adhesive layer, which is a strip that attaches the pad to the underwear. The adhesive is typically made from a pressure-sensitive glue, which can be removed easily without damaging the underwear.
How pads work
Sanitary pads work by absorbing menstrual blood and preventing it from leaking onto clothing and bedding. Upon contact with the pad’s top layer, menstrual blood is drawn towards the absorbent core, where it is absorbed and trapped. The absorbent core’s structure enables it to hold a significant amount of fluid, which can be up to four times its weight.
During periods, the uterus sheds its inner lining, which consists of blood and tissues. This shedding happens intermittently, which means that blood flow can be heavy at times and light at others. Pads are designed to cater to varying levels of blood flow. Absorbent cores can hold more blood than is usually expelled during a menstrual cycle, thus ensuring that the user remains protected from leakage.
The waterproof barrier located between the absorbent core and the bottom layer prevents menstrual blood from leaking onto clothing and bedding. The barrier can withstand pressure, ensuring that even when the pad is compressed, menstrual blood does not escape onto the user’s underwear.
Types of pads
There are two main types of pads; disposable and reusable pads. Disposable pads are the most commonly used type of pad and are designed to be used once and disposed of. They are convenient and hygienic, making them suitable for use in public restrooms or when traveling.
Reusable pads, on the other hand, are designed to be washed and reused several times. They are environmentally friendly and economically viable, making them an excellent option for users who are conscious about their impact on the environment. Many reusable pads are made from soft, breathable materials such as cotton or bamboo, which are gentle on the skin.
Pads versus other menstrual products
Pads are not the only menstrual product available in the market. Other popular options include tampons, menstrual cups, and period panties. Tampons are small cylindrical plugs made from absorbent materials such as cotton or rayon. They are inserted into the vagina and can hold more blood than pads. Menstrual cups are bell-shaped devices that are inserted into the vagina to collect menstrual blood. Unlike tampons, menstrual cups are reusable and can hold significantly more blood. Period panties are underwear designed to absorb menstrual blood and prevent leakage.
While all these menstrual products serve the same function, they differ in terms of their usage and effectiveness. Pads are convenient to use and do not require any insertion, making them ideal for users who are uncomfortable with inserting objects into their vagina. They also provide ample coverage, ensuring that users remain protected from leaks.
Conclusion
Menstruation is a natural and essential part of a woman’s life. Sanitary pads have made managing menstrual periods more convenient and comfortable. Pads work by absorbing menstrual blood and preventing leakage. They come in two main types, disposable and reusable, providing users with options based on their preferences and priorities. While pads are one of the most commonly used menstrual products, users can choose from several others, including tampons, menstrual cups, and period panties. Ultimately, the choice of menstrual product is subjective, and users should choose one that meets their needs.
