3. The strong bonding points which are further improved and arranged have enough strong bonding force, so that the strong bonding points can not be propped by the expanded SAP particles, the SAP after being expanded by the absorption liquid can be limited, and the delamination and sliding accumulation of the expanded SAP can be prevented; and by configuring the parameter ranges and proportional relations of the hot melt adhesive such as the adhesive coating area, the thickness and the like, the effects of no fault and large absorption capacity of the core bottom are achieved.

4. The corresponding position of parcel layer and lower parcel layer forms the recess on making strong tie point to can form unobstructed guiding gutter, form the water conservancy diversion effect to the flow of liquid when absorbing liquid, thereby make the absorption more even.

5. The surface of the core body after absorbing urine forms a continuous concave-convex surface, so that the contact area between the skin of a user and a wet part is reduced, and the comfort of the hygienic product is further ensured.
