Factors and Characteristics of Quality Sanitary Napkin Raw Materials

Sanitary napkins, also known as menstrual pads, are an essential product for women during their menstrual cycle. The quality of the sanitary napkin raw materials used to assemble these products is crucial, as it affects not only the comfort but also the hygiene and health of women. Here are some essential factors and characteristics of quality Sanitary Napkin Raw Materials.

Absorbent Core:

The absorbent core is the primary component of the sanitary napkin, responsible for absorbing and retaining menstrual flow. The most commonly used materials for absorbent core are fluff pulp and superabsorbent polymer (SAP).

Fluff pulp is made from wood fibers and is natural, eco-friendly, and biodegradable. It is also soft and has excellent wicking properties.

SAP is synthetic and can absorb several times its weight in fluid, making it highly effective in retaining liquids. However, it can be expensive and may cause skin irritation if not changed frequently.

The right choice of absorbent materials depends on several factors, such as cost, environmental impact, and user requirements.

Top Sheet:

The top sheet is the layer in contact with the skin, and it should be soft, comfortable, and breathable. The most common materials for top sheets are Non-woven fabrics, such as polypropylene and polyester.

Polypropylene is breathable and water-resistant, making it ideal for use in sanitary napkins. It’s also inexpensive and has good durability.

Polyester is soft, comfortable, and offers excellent moisture wicking properties. However, it may be costly compared to polypropylene.

Back Sheet:

The back sheet is the outermost layer of the sanitary napkin and should prevent leakage and provide a smooth surface for the adhesive layer. The most commonly used materials for back sheets are polyethylene and polypropylene.

Polyethylene is water-resistant and cost-effective. However, it may not be breathable, which can cause discomfort and irritation.

Polypropylene is breathable and offers good strength and durability. It also allows air to circulate, reducing the risk of bacterial growth.

Conclusion:

The right choice of sanitary napkin raw materials is essential for comfort, hygiene, and women’s health. Factors such as cost, performance, and environmental impact should be carefully considered when selecting the materials for the absorbent core, top sheet, and back sheet. By understanding the different properties of each material, manufacturers can produce sanitary napkins that are not only effective in managing menstrual flow but also provide comfort and protection to women.
