The invention adopts a new synchronous split-level process; that is, a linear grid-shaped trapezoid-shaped compaction mechanism, of which the height is smaller than that of a circular-platform structure, incompletely compacts the absorbent core and separates the absorbent core into numerous small convex spaces, while a circular-platform structure carries out the dot-shaped compaction for the absorbent core. Under the conditions that the liquid-absorption functions of a deflector layer and a reservoir layer are maintained, the movement of polymer water-absorption material is completely limited while the strength of a core body is enhanced. The invention adjusts the structure of the core body and a process of preparing it, thus facilitating the improved multilayer structure to have more liquid-absorption amount, faster liquid-absorption speed and increased strength. 1.
