Therefore, all other embodiments obtained by a person of ordinary skill in the art without creative efforts based on the embodiments of the present invention shall fall within the protection scope of the present invention.
Examples
As shown in fig. 1-2, a baby diaper with fixed-point high absorption effect comprises a diaper body 1, wherein the diaper body 1 is sequentially provided with a skin-friendly layer 2, an absorption core body 3, a water-repellent bottom film 4 and a casting film 5 from top to bottom.
The whole absorbing core body 3 is formed by sequentially laminating and bonding a non-woven fabric surface layer 6, a high-molecular water-absorbent resin 7 and a fluffy non-woven fabric 8 from top to bottom.
As shown in FIG. 3, the absorbent core 3 can be divided into three parts of a core front part 9, a core middle part 10 and a core back part 11 according to the front and back positions, wherein the thickness of the high molecular water absorbent resin 7 in the core middle part 10 is 1.5-3 times of the thickness of the high molecular water absorbent resin 7 in the core front part 9 and the core back part 11. Thus, the core middle part 10 can absorb urine with larger flow, and the usage amount of the high molecular water-absorbent resin 7 at the core front part 9 and the core rear part 11 is reduced, so that the production cost of the core can be reduced.
The macromolecule water-absorbing resin 7 can expand and become after absorbing urine, so if the thickness of the macromolecule water-absorbing resin 7 is too large, the macromolecule water-absorbing resin 7 on the upper layer can be caused to absorb water and expand, and then the expanded macromolecule water-absorbing resin 7 sticks together, so that the urine is prevented from leaking downwards, the excessive imbibition of the macromolecule water-absorbing resin 7 on the upper layer is caused, and the macromolecule water-absorbing resin 7 on the lower layer cannot absorb the urine.
Therefore, in the present embodiment, the surface of the core body central portion 10 is further provided with liquid-permeable holes 12 of 1/3-1/2 arranged in a matrix shape and extending downward to the thickness of the high molecular water-absorbent resin 7. When urine contacts core middle part 10, some urine can be absorbed by the polymer water-absorbent resin 7 of upper strata, and another part then can enter into the lower floor of core middle part 10 along weeping hole 12 downwards for the polymer water-absorbent resin 7 that is located the below also can play the effect of absorbing the urine simultaneously, and then has effectively promoted polymer water-absorbent resin 7's utilization ratio and the absorption rate to the urine.
In order to further increase the permeation rate of urine to the core body middle part 10, a bowl-shaped water collecting tank 13 for collecting moisture is arranged at the upper end of the liquid permeating hole 12 in the embodiment, and the diameter of the top of the bowl-shaped water collecting tank 13 is 1.5-2 times that of the liquid permeating hole 12.
When the inner macromolecule absorbent resin 7 absorbs urine, the inner macromolecule absorbent resin can also obstruct the circulation of urine, so the bottom of the liquid seepage hole 12 is provided with the draft tube 14 which is buried in the macromolecule absorbent resin 7, the flow of urine flowing from the liquid seepage hole can be guided, thereby improving the absorption efficiency, simultaneously preventing the urine from being broken after the high molecular water-absorbing resin absorbs water and swells, the draft tube 14 comprises a hollow tube body 15 made of spun-bonded non-woven fabric, hydrophilic non-woven fabric, spunlace non-woven fabric, dust-free paper or cotton and hemp cloth and other materials, and fluff pulp 16 filled in the hollow tube body 15, so that the hollow tube body 15 has good hydrophilic effect, the fluff pulp 16 has both a flow guiding effect and an effect of supporting the hollow tube body 15, and can prevent the failure of the flow guiding effect caused by the extrusion of the draft tube 14 after the high molecular water-absorbent resin 7 expands.
