In the invention, the isolation layer 5 can also be arranged on the liquid-permeable surface layer 1, and the isolation layer 5 is bonded on the upper surface of the liquid-permeable surface layer 1 outside the leakage-proof separation edge 4; after the paper diaper is worn, the isolation layer 5 is in a tension state when being bonded, and the isolation layer 5 is lifted under the action of the leakage-proof separation edges 4 and is erected on the two leakage-proof separation edge rubber bands 42 to be attached to the skin; specifically, the isolation layer 5 can be provided with different layers of netted non-woven fabrics according to the actual required effect, and the isolation layer can be provided with more than one layer.
Meanwhile, as shown in fig. 5, the retaining wall 6 may also be composed of a sheet-like absorbent core 61 adhered to the surface of the liquid-permeable top sheet 1, the sheet-like absorbent core 61 being rotatably disposed on the upper surface of the absorbent body.
In the production process, after the absorber material and the liquid-permeable surface layer 1 material are compounded in the step (1), the sheet-shaped absorption core 61 is bonded on the liquid-permeable surface layer 1 material, so that the bottom of the sheet-shaped absorption core 61 is bonded on the outer surface of the liquid-permeable surface layer 1 to form the retaining walls 6, and the retaining walls 6 are close to the longitudinal two ends of the paper diaper body.
The invention adopts the structure that the isolation layer is arranged on the leakproof isolation edge or the liquid permeability surface layer, after the loose excrement of the baby falls into the absorber, the isolation layer can be isolated from the skin of the baby under the action of the isolation layer, thereby avoiding the direct contact between the skin and the excrement, keeping the skin dry and comfortable, reducing the breeding of bacteria, arranging the isolation layer between the rear waist region and the crotch region of the diaper body, protecting the hip skin of the baby in a targeted manner, and arranging the isolation layers with different lengths according to the size of the product, thereby ensuring the isolation effect, reducing the contact area between the isolation layer and the skin as much as possible under the condition that the excrement does not fall into the absorber, and reducing the use of isolation layer materials; the leakage-proof separation edges are arranged on the two transverse sides of the liquid-permeable surface layer, the composite positions of the leakage-proof separation edges and the liquid-impermeable bottom layer are respectively positioned on the outer edges of the two transverse sides of the absorber, and an interval is arranged between the composite position and the absorber; the retaining walls are arranged at the two longitudinal ends of the paper diaper, so that the two longitudinal ends of the paper diaper also have the functions of leakage prevention and diffusion prevention, the leakage prevention in all directions is realized by matching with the leakage prevention separating edges, and the use effect is good particularly when loose stools are diffused forwards and backwards; the barricade is rotatable structure, when wearing, laminating that can be better can not form the indentation or strain the trace on the human body, has guaranteed the travelling comfort.
While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
