Penetration Rate Of Sanitary Napkin

The faster the penetration rate, the better

Obviously, the faster the liquid is absorbed by the aunt's towel, the more comfortable the skin will feel. This absorption speed is also the penetration speed of the liquid. The penetration is completed by a series of structures, so it is naturally affected by many factors.

Test method: pour the same amount of normal saline on the net surface and record the time. The fastest penetration is the best.

Mesh material: the cotton mesh surface is very loose, and the liquid penetration speed is faster. The dry and dry mesh itself is a waterproof material. After the liquid enters the lower layer through the small hole, it is not easy to return, so the skin will feel more dry.

Diversion channel: after the liquid reaches the mesh surface, it will be evacuated from the concave diversion channel to all directions of the plane. The depth of the diversion channel and the rationality of the channel distribution will affect the diversion speed.

Guide strip: after the liquid passes through the surface layer, a layer of guide strip is required. It is a non-woven fabric with relatively long fiber. Through capillary action, the liquid will quickly diffuse along the fiber to the surrounding and continue to penetrate into the deeper layer. A bad aunt's towel usually doesn't notice this detail.
