[0021] The absorption core 3 is provided with a multi-layer absorption body 37 structure, comprising an upper anti-adhesion non-woven fabric layer 31, an upper SAP layer 32, a fluffy cloth layer 33, a lower SAP layer 34 and a lower water-repellent non-woven fabric layer 35, and the multi-layer structure enables urine to be quickly absorbed and dispersed, the upper anti-adhesion non-woven fabric layer 31 is provided with liquid-permeable holes 311 on the surface, which can quickly guide urine into the absorption body 37, and through the high-efficiency absorption of the upper SAP layer 32 and the lower SAP layer 34 and the diffusion effect of the fluffy cloth layer 33, the urine can be quickly absorbed and dispersed, thereby improving the absorption efficiency and absorption capacity.

[0022] The ice-sensing surface layer 1 comprises an ice-sensing layer 11 and a heat-conducting layer 12, the ice-sensing layer 11 can bring a cool touch and reduce the skin temperature, the heat-conducting layer 12 has good heat-conducting performance and can further adjust the temperature environment inside the paper diaper, maintain the comfort of the baby's skin, the functional flow guide layer 2 is weakly acidic and helps to maintain the acid-base balance on the skin surface, reduce the breeding of bacteria and maintain the health and comfort of the baby's skin, and the bottom layer 4 adopts a composite structure of an ultra-breathable bottom film layer 41 and a breathable non-woven fabric layer 42, which maintains good breathability of the bottom layer 4 and also maintains certain anti-permeation function.

[0023] In addition, the absorption main body is provided with leakage-proof separation edges 5 on both sides in the width direction, which can effectively prevent side leakage of urine and improve the use reliability of the paper diaper.

[0024] As one of the preferred embodiments of the utility model, the ice-sensing layer 11 is made of polyester fiber containing ice-sensing material, and the ice-sensing material is nano-grade jade material particles.

[0025] The ice feeling layer 11 is made of polyester fibers containing ice feeling materials, and the ice feeling materials are selected as nano jade material particles, and the selected nano jade material particles have natural cooling characteristics, and when they are combined with polyester fibers to form the ice feeling layer 11, they can bring an instant cooling feeling to the baby's skin, so that the ice feeling layer 11 can effectively adjust the temperature environment inside the diaper, and the nano jade material particles have good heat conduction performance, which can quickly absorb and disperse the heat on the skin surface, thereby reducing the skin temperature and keeping the baby's skin comfortable and dry.

[0026] As one of the preferred embodiments of the utility model, the heat conducting layer 12 is made of bamboo carbon fiber and chitin fiber, and the heat conducting layer 12 is compounded on the lower surface of the ice feeling layer 11 by an adhesive.

[0027] The heat conducting layer 12 is compounded on the lower surface of the ice feeling layer 11 to form a composite structure, which enhances the overall stability of the diaper, and the selection and use of the adhesive ensure the firm combination between the heat conducting layer 12 and the ice feeling layer 11, avoiding the separation between the layers caused by friction or pulling during use.

[0028] The bamboo carbon fiber and chitin fiber in the heat conducting layer 12 both have good heat conduction performance, the bamboo carbon fiber can effectively absorb and disperse heat due to its microporous structure, and the chitin fiber can further improve the overall performance of the heat conducting layer 12 due to its natural biocompatibility and heat conductivity, so that the heat conducting layer 12 can quickly conduct the heat absorbed by the ice feeling layer 11, thereby accelerating the heat exchange process inside the diaper and keeping the baby's skin cool and comfortable.

[0029] In addition, the heat conduction performance of the heat conducting layer 12 helps to adjust the temperature environment inside the diaper and reduce the local temperature rise caused by urine absorption, thereby avoiding the discomfort of the baby's skin caused by long-term contact with a high-temperature environment, and at the same time, the blended material of bamboo carbon fiber and chitin fiber also has certain moisture absorption and perspiration functions, which can further improve the air permeability and dryness of the diaper and provide a more comfortable wearing experience for the baby's skin.

[0030] As one of the preferred embodiments of the utility model, the functional flow guiding layer 2 is weakly acidic, and the functional flow guiding layer 2 is a non-woven fabric containing acetate fibers or a weakly acidic polylactic acid fiber hot air non-woven fabric.

[0031] The functional flow guide layer 2 is weakly acidic, which is consistent with the natural acid-base environment of the baby's skin, helps to maintain the acid-base balance of the skin surface, can reduce skin problems caused by acid-base imbalance, such as red buttocks and diaper rash, and the weakly acidic environment has a certain inhibitory effect on the growth and reproduction of bacteria. The functional flow guide layer 2 can reduce the breeding of bacteria in the diaper by its weakly acidic properties, thereby reducing the risk of infant skin infection. The acetic acid fiber or weakly acidic polylactic acid fiber in the composition of the functional flow guide layer 2 itself also has certain antibacterial properties, further enhancing the antibacterial effect of the flow guide layer.

[0032] As one of the preferred embodiments of the present application, as shown in Fig. 1 and Fig. 2 The surface of the upper anti-adhesion non-woven fabric layer 31 is provided with a plurality of uniformly distributed liquid-permeable holes 311, the liquid-permeable holes 311 are formed by perforating the surface of the upper anti-adhesion non-woven fabric layer 31, and the liquid-permeable holes 311 are funnel-shaped V-shaped holes.

[0033] The funnel-shaped V-shaped liquid-permeable holes 311 can quickly guide urine to the inside of the absorbent core 3. When the urine contacts the upper anti-adhesion non-woven fabric layer 31, it can quickly and smoothly flow into the absorbent body 37 along the guide of the V-shaped hole, avoiding the retention and diffusion of urine on the surface layer. The uniform distribution of the liquid-permeable holes 311 ensures that the urine can be uniformly absorbed by the absorbent core 3, thereby avoiding excessive concentration of urine in local areas, allowing the absorbent body 37 to fully exert its absorption capacity, improving the overall absorption efficiency and absorption capacity. The rapid flow guiding effect of the liquid-permeable holes 311 allows the urine to be quickly absorbed by the absorbent core 3, thereby keeping the surface of the diaper dry. In addition, the presence of the liquid-permeable holes 311 also enhances the air permeability of the diaper, allowing air to circulate inside the diaper, helping to remove moisture from the absorbent core 3 and keeping the baby's skin breathable and comfortable.

[0034] As one of the preferred embodiments of the present application, the super air permeable bottom film layer 41 is a polytetrafluoroethylene material film with a grammage of 16gsm.

[0035] The microporous structure of the polytetrafluoroethylene (PTFE) material film allows gas to pass easily while effectively blocking liquid. Therefore, as the super air permeable bottom film layer 41 of the diaper, the polytetrafluoroethylene material film provides excellent air permeability, allowing moisture inside the diaper to be quickly removed, keeping the baby's skin dry and comfortable. The grammage of the polytetrafluoroethylene material is 16gsm, making the diaper overall more lightweight. At the same time, the PTFE material itself has good flexibility and durability, which can adapt to various activities of the baby and is not easy to break or tear.

[0036] As one of the preferred embodiments of the present application, as shown in Fig. 3As shown, the air-permeable non-woven fabric layer 42 is compounded on the lower surface of the super air-permeable bottom film layer 41 by an adhesive, and a plurality of air-permeable holes 43 are uniformly distributed on the surface of the air-permeable non-woven fabric layer 42, which are formed by perforating the surface of the air-permeable non-woven fabric layer 42.

[0037] The air-permeable non-woven fabric layer 42 is compounded on the lower surface of the super air-permeable bottom film layer 41 by an adhesive to form a composite structure, so that the bottom layer 4 of the diaper is more firm and durable, and is also helpful to adjust the temperature and humidity inside the diaper. The air-permeable non-woven fabric layer 42 itself has good air permeability, and its fiber structure allows air and water molecules to pass through relatively easily. The air-permeable holes 43 provided on the air-permeable non-woven fabric layer 42 further enhance the air permeability of the bottom layer 4. In addition, the presence of the air-permeable holes 43 allows the moisture inside the diaper to be discharged more quickly, thereby reducing the hindering effect of the moisture on the absorbent core 3, which helps the urine to penetrate into the absorbent body 37 more smoothly, thereby improving the absorption efficiency and speed.

[0038] The above description is only preferred embodiments of the present application, and it should be pointed out that, for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application.
