The structural characteristics and the implementation principle of the invention are as follows: firstly, the side of the pants body far away from the skin of the user is defined as the outer side, and the side close to the skin of the user is defined as the inner side, as shown in fig. 1 and 2 ". "and" x "directions. "indicates the direction of the paper surface outward," x "indicates the direction of the paper surface inward, the airtight bottom layer 1, the core layer 2, the flow guiding layer 3 and the surface layer 4 are stacked in sequence to form the main body part of the trousers body, and the airtight leakproof film material is selected from the airtight bottom layer 1, so that no liquid can seep out of the trousers body, and the waterproof performance can be best under the condition of controllable cost because the air permeability does not need to be considered.

With reference to fig. 3, for the ventilation problem, a mode of introducing and finally penetrating the surface layer 4 from the outside of the pants body, namely the outside of the airtight bottom layer 1, into the inner side of the side close to the skin of the user and then penetrating out of the pants body is set, so that the gas directly enters the pants body from the outside, and along with the movement of the user, the pants body is intermittently extruded by the limbs of the user, and the ventilation efficiency of the fine ventilation pipeline 5 is accelerated; in order to solve the problem of the holes of the air-impermeable bottom layer 1 and other film structures generated by the thin air-permeable pipes 5, the areas where the thin air-permeable pipes and the air-impermeable bottom layer 1, the core layer 2, the flow guide layer 3 and the surface layer 4 meet are all subjected to hot pressing treatment, as shown in the indication range of the hot pressing area shown in fig. 3, 4 and 5, the joint is ensured not to generate gaps so as to allow liquid to flow out, the situation that the liquid is accelerated to flow or seep out due to the material properties of the film layer and the thin air-permeable pipes 5 is avoided, and gas exchange can be generated only at the sections of the thin air-permeable pipes 5 which penetrate through the trousers body and are retained on the inner side of the trousers body.

With reference to fig. 4 and 5, in order to avoid the problem that water seeps from the section of the thin air-permeable pipe 5 inside the pants body, so that the air permeability of the thin air-permeable pipe 5 does not affect the leakage-proof performance, firstly, an impermeable top layer 6 is covered above the section to ensure that direct leakage from the inside of the pants body to the outside does not directly contact with the thin air-permeable pipe 5, secondly, in order to avoid liquid from permeating from the two side wings of the thin air-permeable pipe 5, an impermeable groove 7 is formed in the boundary area of the thin air-permeable pipe 5 and the surface layer 4, namely, the joint by means of hot pressing and the like, so as to form an effect similar to a sewer, so that the liquid permeates into the flow guide layer 3 and the core layer 2 from the surface layer 4 along the impermeable groove 7, and finally, the other positions of the surface layer 4 can still directly contact with the skin of the user, so that the permeation and the water absorption performance of the pants body cannot be affected; on the basis of ensuring that the thin air-permeable pipeline 5 cannot cause the problem of water seepage, the thin air-permeable pipeline is made of a material with good air permeability, so that air entering the pipe body from the outside of the trousers body can permeate the pipe wall of the thin air-permeable pipeline 5 in the trousers body, the air can enter the trousers body, and the problem of air permeability is ensured; in addition, the thin air-permeable pipeline 5 is made of high air-permeable materials and even made in a hole-opening mode, so that the overall structural strength can be reduced, and the hot-pressing area can play a role in strengthening the structural stability of the thin air-permeable pipeline 5 and improving the structural strength of the paper diaper body to a certain extent, thereby achieving multiple purposes.

In summary of the above principles and structural descriptions, the main implementation of the present invention is to realize physical separation and organic integration of ventilation and absorption from the physical structure, so that the cost for selecting the film material can be reduced on the basis of minimum mutual interference, and the low-cost film material with better single performance can exert its own performance advantages as much as possible to avoid its performance disadvantages. Therefore, the diaper can have good air permeability, absorption performance and leakage-proof performance on the premise of good overall cost controllability, limited research and development and production cost can be better returned, customers can obtain good wearing experience, more representative products can be conveniently input and developed by manufacturers, and the output of products with good practicability can be maintained.

Referring to fig. 1, 2 and 5, in a preferred embodiment of the present invention, the two sides of the pants body are provided with side leakage prevention guards 8 which extend from the middle of the pants body to the two sides in the length direction after being tightly pressed with the air-impermeable bottom layer 1, the thin air-permeable pipe 5 passing around the area of the surface layer 4 close to one side of the user is arranged between the side leakage prevention guards 8 and the air-impermeable bottom layer 1 in a penetrating manner, the intersection area of the thin air-permeable pipes 5 is also subjected to heat pressing treatment, and the surrounded part is also provided with the impermeable top layer 6.

Based on the implementation principle of the invention, the embodiment further refines the specific arrangement mode of the side leakage prevention structure and the thin ventilation pipeline 5 of the diaper, and aims to avoid the problem that the side leakage prevention structure cannot be combined with the ventilation structure in related functions, and the side leakage prevention enclosure 8 can be reinforced in the supporting structure thereof after being hot-pressed by the thin ventilation pipeline 5, so that the root of the side leakage prevention enclosure 8 is fluffy by the thin ventilation pipeline 5, the pressure of the side leakage prevention enclosure 8 on the groin of a user can be reduced, and the air can be better extruded by the thigh of the user and then is actively blown to the inner side of the diaper body through the thin ventilation pipeline 5.
