What Constitutes A Sanitary Napkin?

A sanitary napkin, also known as a menstrual pad, is composed of several layers designed to absorb menstrual fluid and provide comfort. Here are the main components:

1. Top Layer: This is the layer that comes in direct contact with the skin. It’s usually made of soft, non-woven fabric to ensure comfort and quick absorption.

2. Absorbent Core: This layer is responsible for absorbing and retaining menstrual fluid. It often contains materials like cellulose fibers and superabsorbent polymers (SAP) that can hold a significant amount of liquid.

3. Bottom Layer: This is the waterproof layer that prevents leakage. It’s typically made of polyethylene or another waterproof material.

4. Adhesive: This is used to keep the pad in place. It is usually applied to the bottom layer and helps the pad stick to underwear.

5. Wings (optional): Some sanitary napkins have wings that wrap around the sides of underwear to provide extra protection against leaks.

These components work together to ensure that the sanitary napkin is effective, comfortable, and secure.
