DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] In order to solve the problems of poor dryness and easy reverse osmosis of sanitary absorbent products in the related art, Figure 1 As shown, the utility model provides a novel sanitary absorbent product, which includes a liquid-permeable surface layer 100, an absorbent main layer 200, a breathable bottom layer 300 and a bottom non-woven fabric 400 arranged in sequence from top to bottom; the absorbent main layer 200 includes a first absorbent layer 201, a second absorbent layer 202 and a third absorbent layer 203, the second absorbent layer is composed of two layers of polyurethane foam, wherein the upper layer of polyurethane foam is provided with a plurality of first funnel-shaped through holes 2021, and the lower layer of polyurethane foam is provided with a plurality of second funnel-shaped through holes 2022, and the first funnel-shaped through holes 2021 and the second funnel-shaped through holes 2022 are symmetrical in the thickness direction.

[0028] In this embodiment, by setting the absorption main layer 200 of the new sanitary absorbent product as the first absorption layer 201, the second absorption layer 202 and the third absorption layer 203, the second absorption layer 202 is composed of two layers of polyurethane foam, and a plurality of funnel-shaped through holes symmetrical in the thickness direction are respectively set in the upper and lower layers of polyurethane foam. In this way, not only the infiltration speed of the liquid in the absorption main layer 200 can be accelerated, but also the storage space of the liquid in the absorption main layer 200 can be increased, so that the sanitary absorbent product has excellent liquid absorption speed and anti-reverse osmosis effect.

[0029] According to some preferred embodiments, the liquid-permeable surface layer 100 is a hot air nonwoven fabric, a spunbond nonwoven fabric, a pure cotton nonwoven fabric or a bamboo fiber nonwoven fabric.

[0030] In this embodiment, the liquid-permeable surface layer 100 is located at the top layer of the sanitary absorbent article and is in direct contact with the user's skin. In order to ensure good softness and that the liquid can quickly penetrate from the liquid-permeable surface layer 100 to the main absorbent layer 200, the liquid-permeable surface layer 100 in this embodiment adopts the above-mentioned type, and more preferably, when the liquid-permeable surface layer 100 is a fine-denier bamboo fiber non-woven fabric, it can not only effectively inhibit the growth of bacteria on the surface of the sanitary absorbent article, but also make the liquid-permeable surface layer 100 have good softness and liquid conductivity. It should be noted that the fiber of the fine-denier bamboo fiber non-woven fabric (made by mixing bamboo fiber and ES fiber, with the mass ratio of bamboo fiber and ES fiber being: 1-10%: 90-99%) is preferably 1 to 1.5 denier.

[0031] According to some preferred embodiments, the first absorption layer 201 is a wet-made super absorbent resin absorbent paper; a plurality of slits are provided on the first absorption layer 201, and the slits are used to accelerate the infiltration of liquid; the length of the slits is 0.5-3 cm (for example, it can be 0.5 cm, 1 cm, 1.5 cm, 2 cm, 2.5 cm, or 3 cm), and the interval between adjacent slits is 1-3 cm (for example, it can be 1 cm, 1.5 cm, 2 cm, 2.5 cm or 3 cm).

[0032] In this embodiment, the first absorption layer 201 in the absorption main body layer 200 is set as a wet-made super absorbent resin absorbent paper, which has good liquid absorption performance and anti-reverse osmosis performance, and further a plurality of slits are set on the super absorbent resin absorbent paper. By controlling the setting length and interval of the slits, it is beneficial to further improve the liquid absorption speed of the absorption main body layer 200, thereby ensuring the good dryness of the liquid-permeable surface layer 100.

[0033] It should be noted that the first absorbent layer 201 in this embodiment can be formed by compounding 1 to 2 layers of super absorbent resin paper, wherein the super absorbent resin paper can be prepared by a common preparation method used by those skilled in the art, for example, it can be compounded by 2 layers of base paper and super absorbent resin, and the weight of the super absorbent resin paper is 50-180g / m 2 .

[0034] According to some preferred embodiments, the thickness of the upper layer of polyurethane foam and the thickness of the lower layer of polyurethane foam are both 2-10 mm (for example, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm or 10 mm).

[0035] like Figure 2 As shown, according to some preferred embodiments, the first funnel-shaped through hole 2021 and the second funnel-shaped through hole 2022 have the same size; the depth of the upper surface of the first funnel-shaped through hole 2021 and the depth of the lower surface of the second funnel-shaped through hole 2022 are both 2-8 mm (for example, they can be 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm or 8 mm), and the width is 2-15 mm (for example, they can be 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10mm, 11mm, 12mm, 13mm, 14mm or 15mm); the depth of the lower surface of the first funnel-shaped through hole 2021 and the depth of the upper surface of the second funnel-shaped through hole 2022 are both 1-2mm (for example, 1mm, 1.5mm or 2mm), and the width is 2-15mm (for example, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm or 15mm).

[0036] like Figure 2 As shown in , in this embodiment, the second absorption layer 202 is composed of two layers of polyurethane foam, which can ensure that the second absorption layer 202 has good liquid absorption and liquid retention performance, and a plurality of funnel-shaped through holes are respectively arranged on the upper polyurethane foam and the lower polyurethane foam, and the funnel-shaped through holes in the upper polyurethane foam and the funnel-shaped through holes in the lower polyurethane foam are symmetrical to each other. When the liquid infiltrates from the first absorption layer 201 to the second absorption layer 202, the liquid can quickly infiltrate through the first funnel-shaped through hole 2021 in the upper polyurethane foam and the second funnel-shaped through hole 2022 in the lower polyurethane foam, thereby ensuring a faster infiltration speed of the liquid, and the second funnel-shaped through hole 2022 and the second funnel-shaped through hole 2022 can increase the surface area of ​​the second absorption layer 202, so that the storage space of the liquid is increased, and at the same time, the liquid can be prevented from infiltrating back to the first absorption layer 201. In this way, the sanitary absorbent product can have both excellent liquid absorption speed and anti-reverse osmosis effect.

[0037] It should be noted that, in this embodiment, the depth and width of the upper surface of the first funnel-shaped through hole 2021 specifically refer to the depth and width of the through hole at the junction of the first funnel-shaped through hole 2021 and the first absorption layer 201, and the depth and width of the lower surface of the first funnel-shaped through hole 2021 specifically refer to the depth and width of the through hole at the junction of the first funnel-shaped through hole 2021 and the lower layer of polyurethane foam.

[0038] According to some preferred embodiments, the lower ends of the first funnel-shaped through holes 2021 are connected to the lower ends of the second funnel-shaped through holes 2022 , so that a plurality of hourglass-shaped through holes are formed in the second absorption layer 202 .

[0039] Continue to refer Figure 2 In this embodiment, the lower end of the first funnel-shaped through hole 2021 in the upper layer of polyurethane foam is connected to the lower end of the second funnel-shaped through hole 2022 in the lower layer of polyurethane foam, so that the through holes in the second absorption layer 202 are hourglass-shaped as a whole. In this way, when a large amount of liquid seeps into the second absorption layer 202, the upper layer of polyurethane foam can first store most of the liquid in the upper half of the first funnel-shaped through hole 2021, and then a large amount of liquid from the lower half of the first funnel-shaped through hole 2021 and the upper half of the second funnel-shaped through hole 2022 seeps into the lower half of the second funnel-shaped through hole 2022 of the lower layer of polyurethane foam, and part of the liquid can be further absorbed by the surrounding polyurethane foam in the process of layer-by-layer infiltration; in this way, not only can the absorption main layer 200 absorb a large amount of liquid, but also it has excellent liquid absorption speed and anti-reverse osmosis effect.

[0040] According to some preferred embodiments, the third absorption layer 203 is composed of highly water-absorbent resin and fluff pulp.

[0041] In this embodiment, a third absorption layer 203 composed of a highly absorbent resin and fluff pulp is arranged below the second absorption layer 202. The absorption layer has a good liquid diffusion effect, so that a large amount of liquid that seeps into the lower half of the second hourglass-shaped through hole can be quickly diffused, thereby further improving the liquid absorption speed of the absorption main layer 200 and further preventing liquid reverse osmosis.

[0042] It should be noted that this embodiment has no particular restriction on the mass ratio of the super absorbent resin and the fluff pulp in the third absorbent layer 203, as long as the third absorbent layer 203 has a good liquid diffusion rate and liquid absorption rate. For example, the mass ratio of the super absorbent resin and the fluff pulp can be (1-4):(5-7).

[0043] According to some preferred embodiments, the sanitary absorbent product further comprises a wrapping layer 600, and the wrapping layer 600 is used to wrap the absorbent main layer 200; the wrapping layer 600 is a spunbonded nonwoven fabric, and the side in contact with the liquid-permeable surface layer 100 is sprayed with an antibacterial factor.

[0044] like Figure 3 As shown, in this embodiment, the sanitary absorbent article further comprises a wrapping layer 600, which is located below the liquid-permeable surface layer 100. The wrapping layer 600 can prevent the layers of the absorbent main layer 200 from being misaligned with each other, thereby ensuring good liquid absorption performance of the absorbent main layer 200. At the same time, the side of the wrapping layer 600 that is in contact with the liquid-permeable surface layer 100 is sprayed with an antibacterial factor, so that the sanitary absorbent article can have good antibacterial and deodorizing performance.

[0045] It should be noted that the antibacterial factor can be a common antibacterial factor in the prior art, such as eucalyptus, mugwort or tea polyphenols, and the spraying amount of the antibacterial factor can be selected according to actual needs.

[0046] According to some preferred embodiments, three-dimensional guardrails 500 are further provided on both sides of the liquid-permeable surface layer 100 , and the height of the three-dimensional guardrails 500 is higher than the surface of the liquid-permeable surface layer 100 .

[0047] In the utility model, Figure 3 As shown, three-dimensional guards 500 higher than the liquid-permeable surface layer 100 are provided on both sides of the liquid-permeable surface layer 100. The three-dimensional guards 500 can be higher than the liquid-permeable surface layer 100, with a height of 1 to 4 cm, and can effectively prevent liquid leakage. The three-dimensional guards 500 can be made of water-repellent non-woven fabric wrapped with elastic band.

[0048] According to some preferred embodiments, the breathable bottom layer 300 is a PE breathable film, and the bottom layer non-woven fabric 400 is a hot air non-woven fabric or a spunbond non-woven fabric.
