Sanitary pads are essential products used by women during their menstrual cycles. The composition of sanitary pads plays a crucial role in their effectiveness and comfort. In this article, we will explore the essential materials used in sanitary pad composition, highlighting their importance and benefits.

1. Absorbent Core


The absorbent core is the heart of a sanitary pad, responsible for absorbing and locking away menstrual flow. Most commonly, the core is made from a combination of wood pulp and superabsorbent polymers (SAPs). Wood pulp provides excellent fluid retention capacity, while SAPs enhance absorption efficiency, preventing leakage and keeping the surface dry.

Other materials, such as natural fibers like cotton or bamboo, can also be included to increase the pad's softness and breathability. These materials help to minimize skin irritation and make the pad more comfortable to wear.

2. Top Sheet

Hot air non woven

The top sheet of a sanitary pad is in direct contact with the skin. It is typically made from non-woven fabrics, which are highly permeable and allow for quick penetration of menstrual flow into the absorbent core. Non-woven fabrics also ensure that the pad stays dry and prevents moisture from coming back to the surface.

To enhance comfort, manufacturers often incorporate a layer of perforated film on the top sheet. This film helps to distribute the liquid evenly throughout the pad, preventing clumping and ensuring a more uniform absorption. Additionally, it prevents backflow, improving leakage protection.

3. Back Sheet

Air through non woven

The back sheet of a sanitary pad is the outermost layer, in contact with undergarments. Its primary function is to provide leak-proof protection and prevent any liquid from seeping through. Back sheets are typically made from polyethylene or biodegradable materials, which are impermeable to fluids.

Some manufacturers have also started using breathable materials for the back sheet, allowing air circulation and reducing heat build-up. This helps to prevent discomfort and minimize the risk of bacterial growth.

In conclusion, the composition of sanitary pads involves various materials carefully selected to provide optimal absorbency, comfort, and leakage protection. The absorbent core, top sheet, and back sheet are essential components that contribute to the overall performance of sanitary pads. By understanding these materials, women can make informed choices when selecting the most suitable sanitary pad for their needs.
