Sanitary pads are an indispensable part of feminine hygiene products and are of great significance to women's health and comfort. However, do you really know what sanitary pads are made of? This article will reveal the composition and structure of sanitary pads to help you better understand this commonly used product in daily life.
★ Main components of sanitary pads
1. Absorbent layer:
The core part of sanitary napkins is the absorbent layer, which is responsible for absorbing and fixing menstrual blood. Common absorbent layer materials include:
✿Pure cotton: Pure cotton fibers absorb quickly, have good breathability, are gentle on the skin, and reduce the risk of allergies.
✿Ultra-thin absorption layer: Made of high-molecular water-absorbent material, it absorbs quickly and can effectively keep you dry.
2. Anion chip layer (internal structure):
In some advanced sanitary napkins, the chip layer is used to improve absorption capacity, prevent leakage and keep dry. It is usually composed of polymer materials such as gel microfilaments.
3. Backsheet film:
The backsheet film is made of a breathable film to prevent leakage and maintain comfort.
4. Surface layer (surface layer):
The surface layer contacts the skin and its function is to be soft, breathable, and able to transfer liquid downward to keep the surface dry. It is usually made of non-woven fabric or perforated film.
5. Adhesive:
Adhesives are indispensable for combining materials of various layers. Generally, non-toxic and odorless hot melt adhesives are widely used.
Sanitary pads are usually packaged in polyethylene or polypropylene film to maintain the hygiene and integrity of the product.
★ Structure of sanitary pads
1. Wings:
The wings are located on both sides of the sanitary napkin and can be fixed on the underwear to provide better leakage protection.
2. Tape:
There is usually a layer of tape on the back of the sanitary napkin to facilitate the user to fix it on the underwear.
Sanitary pads are made of a variety of materials, and the central absorption layer, core layer, backing layer and surface layer play different functional roles. Understanding the composition and structure of sanitary pads can help us choose the right product for ourselves and improve comfort and safety. When buying sanitary napkins, it is very important to choose the type and specification that suits you according to your personal preferences and needs.
