X" in figures 1 and 2, the ". cndot" indicates the direction out of the paper surface, and the ". cndot" indicates the direction in the paper surface, the air-impermeable bottom layer 1, thecore layer 2, theflow guide layer 3 and thesurface layer 4 are sequentially stacked to form the main body part of the trouser body, the air-impermeable leakproof film material is selected from the air-impermeable bottom layer 1 to ensure that no liquid can seep out of the trouser 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 thesurface layer 4 from the outside of the pants body, namely the outside of theairtight 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 thefine 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 fine air-permeable pipes 5, the areas where the fine air-permeable pipes and the air-impermeable bottom layer 1, thecore layer 2, theflow guide layer 3 and thesurface layer 4 meet are 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 to allow liquid to flow out, the situation that the liquid flows or seeps out at an accelerated speed due to the material properties of the film layers and the fine air-permeable pipes 5 is avoided, and gas exchange can be generated only between the subsection of the fine air-permeable pipes 5 which penetrate through the trousers body and are retained on the inner side of the trousers body and the trousers body.

Referring to fig. 4 and 5, in order to avoid the water seepage problem of the section of the thin air-permeable pipe 5 which is reserved at the inner side of the trousers body, so that the air permeability of the section does not affect the leakage-proof capability, firstly, an impermeabletop layer 6 is covered above the section to ensure that the direct leakage from the inner side of the trousers body to the outer side does not directly contact with the thin air-permeable pipe 5, secondly, in order to avoid the liquid from permeating from the two side wings of the thin air-permeable pipeline 5, ananti-seepage groove 7 is formed in the interface area of the thin air-permeable pipeline 5 and thesurface layer 4, namely the joint by hot pressing and the like, so as to form the effect similar to a sewer, so that the liquid can permeate from thesurface layer 4 to theflow guide layer 3 and thecore layer 2 along theanti-seepage groove 7, and finally, the other positions of thesurface layer 4 can still be directly contacted with the skin of a user, so that the permeation and the water absorption performance of the trousers body can not be influenced; 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.
