The abdomen and back water absorption wrapping area 1 is contacted with a human body through the skin sticking surface layer 11, so that the contact comfort degree is improved; the flow guide layer 15 plays a role in guiding liquid to the water absorption fiber layer 16, and when the water absorption fiber layer 16 is high in local humidity and cannot absorb liquid effectively, the flow guide layer 15 is provided with an area which can guide the liquid to the water absorption fiber layer 16 and is high in absorption capacity, and therefore the liquid absorption efficiency is improved; the leakage-proof bottom film is a PE film layer, so that an effective leakage-proof effect is realized, and the use effect of the incontinence product in the form of the underpants is prevented from being influenced by liquid leakage. The absorbent fiber layer 16 includes a plurality of polygonal frames 161 distributed in an array, and two adjacent polygonal frames 161 are communicated with each other. Meanwhile, a frame body cavity 163 is provided in the polygonal frame body 161, and the frame body cavity 163 is filled with a water absorbing material. Therefore, the absorbent fabric layer 16 isolates the liquid in the corresponding polygonal frame body 161 through the plurality of mutually communicated polygonal frame bodies 161 distributed in an array, so that the absorbent material in the corresponding polygonal frame body 161 influences the absorbent material in the adjacent polygonal frame body 161 when expanding after absorbing the liquid, thereby improving the liquid absorption capacity of the absorbent material in the polygonal frame body 161, and the incontinence article in the form of underpants has the effect of realizing a remarkable improvement in liquid absorption to avoid liquid leakage.

The polygonal frame 161 is a regular polygon having 2n sides, and n is a positive integer. The plurality of polygonal frames 161 are arrayed along the symmetrical included angle directions thereof. Therefore, 2n side edges and the polygonal frame body 161 which is a regular polygon have even number of side edges, and then n side edges are formed along the symmetrical included angle direction to be distributed for the polygonal frame body 161 in an array manner, so that the polygonal frame body 161 forms a connecting structure with high stability, and the liquid absorption effect of the incontinence product in the underwear form is improved by the mutual cooperation of the two adjacent polygonal frame bodies 161 through the mutually communicated structure, thereby effectively avoiding liquid leakage.

As shown in fig. 3 and 4, the polygonal frame 161 is provided with 2n frame corners 162 distributed in an equal arc, and two frame corners 162 of two adjacent polygonal frames 161 intersect with each other, and an intersection cavity 164 located between the two frame corners 162 is formed.

The plurality of polygonal frames 161 located on the outer peripheral side of the water-absorbent fiber layer 16 are formed with outer peripheral side edges 165 matching the outer peripheral side of the water-absorbent fiber layer 16. When the incontinence product in the form of underpants is used, the rectangular connecting section b with the unchanged width is absorbed by the trapezoidal expansion section a with the gradually increased width, so that liquid which is difficult to absorb and flows to the trapezoidal expansion section a is absorbed, and the aim of avoiding leakage is fulfilled; in the actual use process, a small part of liquid is released from the isosceles triangular reduced sections c with gradually reduced width and is absorbed correspondingly, so that the liquid is effectively absorbed, and meanwhile, the liquid is dispersed in the two corresponding isosceles triangular reduced sections c, the effect of avoiding excessive contact with a human body is realized, and the purpose of improving the use comfort level is realized.

Therefore, when arranging the hydrophobic ring body 12 of the same width on one side of the periphery of the absorbent fibrous layer 16, the problem of leakage of liquid from the outer side of the hydrophobic ring body 12 of the box of the absorbent fibrous layer 16 is effectively avoided, and then the liquid is guided to be gradually and completely absorbed along the absorbent fibrous layer 16, so that the liquid leakage is effectively avoided while the liquid absorption efficiency and effect are remarkably improved.

Wherein, the hydrophobic ring body 12 consists of 15 to 20 weight parts of hydrophobic breathable polypropylene, 6 to 8 weight parts of silk fiber, 6 to 8 weight parts of cotton fiber and 0.5 to 0.8 weight part of nano titanium dioxide; and the preparation step of the hydrophobic ring body 12 comprises a, blending hydrophobic breathable polypropylene fibers, silk fibers and cotton fibers into silk according to the corresponding weight part ratio at the temperature of 55-65 ℃ to obtain hydrophobic soft silk threads; b. soaking the hydrophobic soft silk threads into titanium dioxide sol for finishing, and drying to obtain hydrophobic loop threads; c. the hydrophobic loop wires are woven into the hydrophobic loop body 12, so that hydrophobic soft silk threads are prepared by combining the hydrophobic breathable polypropylene fibers, the silk fibers and the cotton fibers in corresponding parts by weight, and then the hydrophobic loop body 12 with a high-efficiency hydrophobic effect is formed by weaving after titanium dioxide sol treatment, so that the incontinence product in the underwear form has the effect of effectively avoiding liquid leakage. Meanwhile, the super absorbent fiber SAF and the water absorbent resin SAP are formed in an embedded filling mode. The embedded filling mode specifically comprises the steps of preparing the water-absorbent resin SAP into non-woven fabric layers with different thicknesses, filling the non-woven fabric layers with super-absorbent fibers SAF with the same mass, and sequentially pasting and forming the non-woven fabric layers with different thicknesses and filled with the super-absorbent fibers SAF according to the thicknesses, wherein the non-woven fabric layers at least comprise three layers. Therefore, while the preparation and acquisition difficulty of the water-absorbing material is remarkably reduced, the liquid can be absorbed layer by layer and the leakage can be controlled on the premise of effectively carrying the super absorbent fiber SAF under the support of the water-absorbing resin SAP, so that the incontinence product in the form of the underpants has the effect of remarkably improving the liquid absorption to avoid liquid leakage.

The water-absorbent fiber layer 16 includes a plurality of polygonal frames 161 distributed in an array, and two adjacent polygonal frames 161 are communicated with each other. Meanwhile, a frame body cavity 163 is provided in the polygonal frame body 161, and the frame body cavity 163 is filled with a water absorbing material. Therefore, the absorbent fiber layer 16 isolates the liquid in the corresponding polygonal frame body 161 through the plurality of mutually communicated polygonal frame bodies 161 distributed in an array, so that the absorbent material in the corresponding polygonal frame body 161 influences the absorbent material in the adjacent polygonal frame body 161 when expanding after absorbing the liquid, thereby improving the liquid absorption capacity of the absorbent material in the polygonal frame body 161, and the incontinence product in the form of underpants has the effect of realizing remarkable improvement of liquid absorption to avoid liquid leakage.
