INDUSTRIAL APPLICABILITY

(66) When the body fluid reaches the first fiber layer, which has low surface energy, it then flows to the second fiber layer through the through holes of the first fiber layer, so that it not only has a distributing function, but also enlarges the diffusing area, thus increasing the effective use area of the absorbent product and improving the absorbent performance on the liquid; as the second fiber layer has higher surface energy, so that when the body fluid reaches the second fiber layer, it is quickly absorbed into the layer.
