These three components, the top layer, the absorbent layer, and the barrier film, allow liquid to flow through their interface. The crucial element in determining how well a sanitary napkin performs is mostly found in the absorbent portion. We must consider the flow channel of fluid through each layer of a sanitary pad to comprehend the basic operation of sanitary napkins.

Barrier layer: As liquid encounters the first layer vertically, it passes through the fluid acquisition layer and into the absorbent layer without spreading into the facing layer. When liquid enters the absorbent layer, it spreads and can be retained without changing the flow's direction.

The interface between the acquisition layer and the absorbent layer is the first issue with sanitary pads. The fluid must be easily moved from the acquisition layer to the absorbing medium since the acquisition layer is mostly made up of hydrophobic fibers and the absorbent layer is made up of hydrophilic fibers. Lack of intimate contact between the two layers will prevent fluid from moving from one layer to the next. Any opening will alter the flow pattern, and leaking liquid could cause the product to malfunction.

Fluffed cellulosic pulp serves as the primary component of the absorbent material in almost all sanitary pads. This fluff is made by defibrillating compressed cellulose boards that have not been opened. There is always a potential that there will be some unopened board, which offers absorbent material heterogeneity. As a result, there will be different fluid flow and retention than the rest of the area.

The ability of sanitary pads to retain fluid or the volume of fluid that remains after applying pressure can be used to assess their performance. Density is one element that influences fluid retention. Super absorbent fiber is utilized in both compressed and uncompressed forms to make modern commercial sanitary pads.

The product's absorption and stability are greatly impacted by density. A fiber that has been firmly compressed will expand upon absorption, but a fiber that has been loosely compressed will collapse. To retain the structural integrity of the absorbent material, compression is therefore required.

All the above qualities of a good performance sanitary pad can be found only in the Kedi 7-Layer Sanitary Pad where the functions of its 7 layers are listed below:

Layer 1 = Soft cotton surface with rapid absorption

Layer 2 = Active Oxygen and negative ions with anti-bacteria function

Layer 3 = Air-laid paper wrapped.

Layer 4 = Super absorbent polymer

Layer 5 = Breathable layer

Layer 6 = Adhesive layer

Layer 7 = Dust-proof layer

Why wait to use the Kedi 7-Layer sanitary Pad when you now know how a good sanitary pad works?
