摘要：
The present invention relates to a unitary absorbent structure and method thereof wherein said unitary absorbent structure comprises an absorbent core (5) and/or an acquisition and dispersion layers (2) (3) and comprising at least one non- woven fibrous substrate layer (23) having a void volume suitable to be penetrated by super absorbent particles. The super absorbent particles are dispersed in the substrate layer (23) according to a size distribution gradient by vacuum (8') and vibration along the depth direction or z-direction of said absorbent core (5) and/or acquisition (2) and dispersion (3) layers, the smaller particles are placed on the bodyside of th e absorbent articles and the larger particles are located on the opposite side of the absorbent articles.
