[0033] The present application will be described in detail below in conjunction with the drawings and embodiments. It can be understood that all the structural schematic diagrams of the breathable and quickly absorbent absorbent articles of the present application are structural logic schematics. For the specific connection structure and structural parameters such as the thickness or length between each layer, refer to the structure of actual production. In the following description, specific details such as specific system structures, interfaces, and technologies are proposed for the purpose of illustration rather than limitation, so as to thoroughly understand the present application.

[0034] The present application first provides a packaging structure. Please refer to Figure 1 , Figure 1 It is the structural cross-sectional view of the first embodiment of the breathable and quickly absorbent absorbent article of the present application. As Figure 1 shown, the breathable and quickly absorbent absorbent article 100 provided by the technical solution adopted by the present application can be applied to products that need to absorb liquids, including but not limited to sanitary napkins, and can also be diapers, nursing pads, nursing mats, etc.

[0035] Among them, the absorbent article 100 includes: an absorbent core layer 103 for absorbing liquids;

[0036] Adding a superabsorbent polymer to the absorbent core layer 103 can increase the absorption capacity of the absorbent article 100. In some embodiments, the absorbent core layer 103 can mix the superabsorbent polymer or mix pulverized plant fibers and the superabsorbent polymer or mix plant fibers, chemical fibers and the superabsorbent polymer, and integrally form by a non-woven process.

[0037] The absorbent core layer 103 made of a composite material can reduce the gel effect generated by the superabsorbent polymer after absorbing liquid, and the generated gel effect will also prevent the liquid from seeping down, affecting secondary absorption and multiple absorptions, thereby affecting the air permeability of the absorbent core layer 103 and ensuring the air permeability of the absorbent article 100.

[0038] The liquid-permeable surface layer 101 is disposed on the surface of the absorbent core layer 103 and on the side of the absorbent article 100 for contacting the skin, and is used for guiding and / or absorbing part of the liquid; the liquid-permeable surface layer 101 is formed with holes 102 so that part of the liquid contacts the absorbent core layer 103 through the holes 102.

[0039] The material of the liquid-permeable surface layer 101 can be composed of chemical fibers, natural fibers, or a mixture of chemical fibers and natural fibers. In some embodiments, the chemical fibers are made into the liquid-permeable surface layer 101 of chemical fiber non-woven fabric through a hot air non-woven process. The natural fibers include cotton fibers, silk fibers, hemp fibers, bamboo fibers, etc., and are made into the natural fiber liquid-permeable surface layer 101 through a hydroentangling non-woven process, or the chemical fibers and natural fibers are mixed in a certain proportion to make the liquid-permeable surface layer 101 of a mixed chemical fiber non-woven fabric. The gram weight is between 15 gsm and 55 gsm, and can be 15 gsm, 18 gsm, 20 gsm, 25 gsm, 30 gsm, 32 gsm, 35.5 gsm, 40 gsm, 50 gsm, 55 gsm, etc.

[0040] In the liquid-permeable surface layer 101, especially in the area for skin contact, the skin contact area is reduced through a punching technique, thereby increasing air permeability. The aperture size of the punched holes in the liquid-permeable surface layer 101 is between 0.3 mm and 2 mm, and can be 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, 0.7 mm, 0.9 mm, 1.0 mm, 1.5 mm, 2 mm, etc. The aperture sizes of the punched holes can be equal or unequal, and can be distributed in a matrix, circularly, or randomly, etc. In some embodiments, the aperture or density of the holes 102 in the middle area can be larger than that of the surrounding holes 102 to improve the absorption performance and air permeability. The embossing technique can also be used to further reduce the skin contact area.

[0041] The leak-proof bottom film layer 104 is disposed on the side of the absorbent core layer 103 away from the skin.

[0042] The leak-proof bottom film layer 104 can use a PE (Polyethylene) film, especially including a breathable PE film. The principle of breathable but water-impermeable of the breathable PE film can be utilized to achieve a higher air permeability of the absorbent article 100.

[0043] The layers of the absorbent object can be adhesively fixed at the edges with sticky substances such as glue and hot melt adhesive to improve the air permeability of the skin contact surface of the absorbent article 100.

[0044] Please refer to Figure 2 , Figure 2 which is a structural cross-sectional view of the second embodiment of the breathable and quick-absorbing absorbent article of the present application.

[0045] In an alternative embodiment, the liquid-permeable surface layer 101 includes a first liquid-permeable surface layer 1011 and a second liquid-permeable surface layer 1012. The second liquid-permeable surface layer 1012 is disposed between the first liquid-permeable surface layer 1011 and the absorbent core layer 103.

[0046] The materials of the two liquid-permeable surface layers 101 can be the same or different, and the thicknesses can also be the same or different, and can be composed of chemical fibers, natural fibers or a mixture of chemical fibers and natural fibers.

[0047] There can be a gap or a fit between the first liquid-permeable surface layer 1011 and the second liquid-permeable surface layer 1012, and there can also be a fit or a gap between the second liquid-permeable surface layer 1012 and the absorbent core layer 103, which is selected according to the specific production situation. In one embodiment, the structure with a gap can increase a certain air permeability.

[0048] The first liquid-permeable surface layer 1011 is formed with first holes 1021 therethrough, and the second liquid-permeable surface layer 1012 is formed with second holes 1022 therethrough; at least part of the positions of the first holes 1021 correspond to at least part of the positions of the second holes 1022, so that part of the liquid contacts the second liquid-permeable surface layer 1012 through the first holes 1021, and / or contacts the absorbent core layer 103 through the first holes 1021 and the second holes 1022.

[0049] After the liquid contacts the first liquid-permeable surface layer 1011, part of the liquid seeps through the first liquid-permeable surface layer 1011 to the second liquid-permeable surface layer 1012 and is then absorbed. The first holes 1021 and the second holes 1022 can all correspond one by one, so that the liquid can be quickly diverted to the absorbent core layer 103 when contacting the absorbent article 100. In some embodiments, part of the first holes 1021 and the second holes 1022 can also communicate with each other. The numbers of the first holes 1021 and the second holes 1022 can be the same or different. It can be that the number of the first holes 1021 is more than the number of the second holes 1022, or it can be that the number of the first holes 1021 is less than the number of the second holes 1022. The pore diameters of the first holes 1021 and the second holes 1022 can be equal or unequal, and can be distributed in a matrix, circular or random distribution, etc. In some embodiments, the pore diameter or density of the holes 102 in the middle region can be larger than that of the holes 102 in the surrounding area to improve the absorption performance and air permeability.

[0050] Both the first liquid-permeable surface layer 1011 and the second liquid-permeable surface layer 1012 can adopt embossing technology to further reduce the skin contact area or improve breathability.

[0051] In other embodiments, a third liquid-permeable surface layer with holes or more than three liquid-permeable surface layers can also be provided to improve the comfort or softness of the side contacting the skin.

[0052] Please refer to Figure 3 and Figure 4 , Figure 3 which is a structural cross-sectional view of the third embodiment of the breathable and fast-absorbing absorbent article of the present application. Figure 4 which is a schematic diagram of the perforated structure of the third embodiment of the breathable and fast-absorbing absorbent article of the present application.

[0053] The absorbent core layer 103 is provided with third holes 1031 formed therethrough, so that liquid enters the inside of the absorbent core layer 103 through the third holes 1031 and / or contacts the leak-proof bottom film layer 104.

[0054] Through the third holes 1031, part of the liquid directly seeps down to the leak-proof bottom film layer 104 through the punctured holes for absorption, so that both sides of the absorbent core layer 103 can absorb the liquid, greatly improving the absorption efficiency. Part of the liquid can be absorbed by the hole wall during the process of passing through the third holes 1031, which can also improve the absorption efficiency.

[0055] The third holes 1031 in the absorbent core layer 103 can also be blind holes, which do not directly guide the liquid to the leak-proof bottom film layer 104, but are absorbed by the hole wall or the bottom of the holes 102 in the middle of the absorbent core layer 103, increasing the contact of the liquid with the absorbent material in the absorbent core layer 103.

[0056] In other embodiments, it can also be a single-layer liquid-permeable surface layer 101 or multiple-layer liquid-permeable surface layers 101 stacked on the absorbent core layer 103 to achieve the function of guiding or absorbing liquid.

[0057] Please refer to Figure 5 , Figure 5 which is a structural cross-sectional view of the fourth embodiment of the breathable and fast-absorbing absorbent article of the present application.

[0058] In an alternative embodiment, the absorbent object further includes: a water-repellent surface layer 105, and the water-repellent surface layer 105 is formed with fourth holes 102 (not shown in the figure) therethrough and / or is provided with embossing.

[0059] The liquid-repellent layer 105 is provided at the outer periphery of the absorbent article 100 to prevent liquid from leaking out through the side before being absorbed. A part of the liquid-repellent layer 105 is bent inward into two layers and bonded to improve the adhesion of the liquid-repellent layer 105 to each layer and effectively prevent liquid from penetrating from the side of the absorbent article 100.

[0060] The material of the liquid-repellent layer 105 is mainly composed of chemical fibers. The chemical fibers are made into thermally weathered chemical fiber non-woven fabric through hot air non-woven process, or can be made into spunmelt chemical fiber non-woven fabric through spunmelt non-woven process. Among them, the perforated thermally weathered chemical fiber non-woven fabric can also be realized by the above two methods of online perforation and offline perforation. The spunbond non-woven fabric is adhesively bonded to the upper and lower sides of the meltblown cloth through evenly distributed dot-shaped glue, and can be a three-layer, four-layer, five-layer, or six-layer structure with spunbond non-woven fabric on the upper and lower surfaces and a combination of meltblown + spunbond non-woven fabric in the middle.

[0061] The pore diameter of the perforated thermally weathered chemical fiber non-woven fabric of the liquid-repellent layer 105 is between 0.3 mm and 2 mm, and can be 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, 0.7 mm, 0.9 mm, 1.0 mm, 1.5 mm, 2 mm.

[0062] The gram weight of the material of the perforated thermally weathered chemical fiber non-woven fabric of the liquid-repellent layer 105 is between 15 gsm and 55 gsm, and can be 15 gsm, 18 gsm, 20 gsm, 25 gsm, 30 gsm, 32 gsm, 35.5 gsm, 40 gsm, 50 gsm, 55 gsm, etc. The gram weight of the single-layer spunbond non-woven fabric material is between 3 gsm and 15 gsm, and can be 3 gsm, 3.2 gsm, 3.55 gsm, 4 gsm, 5 gsm, 8 gsm, 10 gsm, 15 gsm, etc. The gram weight of the meltblown non-woven fabric material is between 3 gsm and 15 gsm, and can be 3 gsm, 3.2 gsm, 3.55 gsm, 4 gsm, 5 gsm, 8 gsm, 10 gsm, 15 gsm, etc.

[0063] The diameter of the spunbond pressing points or embossed patterns on the surface of the spunmelt chemical fiber non-woven fabric of the liquid-repellent layer 105 is between 0.45 and 1.5 mm, and can be 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, 0.7 mm, 0.9 mm, 1.0 mm, 1.5 mm.

[0064] Through the setting of perforation or embossing, the air permeability of the liquid-repellent layer 105 in the area in contact with the skin is improved, and the air in the middle will also flow outward, further enhancing the air circulation in the skin contact area of the middle area, effectively improving the air permeability of the whole absorbent article 100.

[0065] The water-repellent top layer 105 is disposed on the side of the absorbent article 100 that contacts the skin, covers a part of the liquid-permeable top layer 101, and is adhered to the leak-proof bottom film layer 104 to fix and / or wrap at least a part of the liquid-permeable top layer 101 and the absorbent core layer 103.

[0066] In an alternative embodiment, the leak-proof bottom film layer 104 is formed with micropores, and embossing is further provided on the side of the leak-proof bottom film layer 104 away from the absorbent core layer 103; the pore size of the micropores is between 10 mm and 100 mm to hinder liquid penetration and allow liquid vapor and / or air flow to pass through.

[0067] The leak-proof bottom layer of the absorbent article 100 uses a breathable PE film, so that the absorbent article 100 has a substantial breathable perception. The leak-proof bottom film 104 is made by blending PE and calcium carbonate through a blow molding or casting process, and the content of calcium carbonate is approximately between 40% and 60%, which can be 40%, 45%, 50%, 55.5%, 58%, 60%, etc. The leak-proof bottom film 104 has many through micropores, and the pore size can be 10 mm, 15 mm, 20 mm, 20.5 mm, 30 mm, 50 mm, 70 mm, 85 mm, 90 mm, 100 mm, etc., so as to achieve the effect of waterproofing but allowing water vapor to pass through.

[0068] The air permeability of the leak-proof bottom film 104 is between 500 and 3000 g / m 2 ·24h, which can be 500 g / m 2 ·24h, 525 g / m 2 ·24h, 550 g / m 2 ·24h, 580 g / m 2 ·24h, 400 g / m 2 ·24h, 500 g / m 2 ·24h, 600 g / m 2 ·24h, 700.5 g / m 2 ·24h, 1000 g / m 2 ·24h, 2000 g / m 2 ·24h, 3000 g / m 2 ·24h, etc. The basis weight of the leak-proof bottom film 104 material is between 25 gsm and 45 gsm, which can be 25 gsm, 28 gsm, 30 gsm, 35 gsm, 40 gsm, 42 gsm, 43.5 gsm, 45 gsm, etc.

[0069] In some embodiments, the exposed side of the leak-proof bottom film 104 can have dot embossing or other embossing indicating breathability, so that users can visually perceive the high breathability of the material.

[0070] After absorbing liquid, since there is no material in the pores, it will not hinder the air circulation after the absorbent core absorbs liquid, and maintain good air permeability of the absorbent article 100.

[0071] Please refer to Figure 6 , Figure 6 which is a structural cross-sectional view of the fifth embodiment of the breathable and fast-absorbing absorbent article of the present application.

[0072] In an alternative embodiment, the liquid-repellent surface layer includes a wrapping liquid-repellent surface layer 1051 that wraps at least part of the liquid-permeable surface layer 101 and the absorbent core layer 103 to form a composite structure; and two side liquid-repellent surface layers 1052 that are partially adhesively disposed between the composite structure and the leak-proof bottom film layer 104 to fix the composite structure.

[0073] The thicknesses of the wrapping liquid-repellent surface layer 1051 and the two side liquid-repellent surface layers 1052 can be the same or different, and the pore diameters or densities of the punched holes can be the same or different. The formed composite structure can prevent liquid from permeating out before being absorbed outside the absorbent object. It can also further strengthen the fixing degree between the layers. Part of the wrapping liquid-repellent surface layer 1051 is bent or folded inward into two layers and adhered to wrap the composite structure, which can improve the adhesion of the liquid-repellent surface layer 105 to each layer and effectively prevent liquid from permeating from the side of the absorbent article 100.

[0074] For the above-mentioned breathable and fast-absorbing absorbent article provided, by punching holes in the liquid-permeable surface layer for skin contact in the middle area of the absorbent article, punching and embossing the liquid-repellent surface layer material of the skin contact layer in the two side areas, puncturing the whole absorbent article or using a dot-permeable PE film for the leak-proof bottom film layer, the air permeability during use is improved. Puncturing the whole absorbent article ensures that air holes are retained after liquid absorption, reduces the reduction of air permeability after absorbing liquid, part of the liquid seeps down to the second liquid-permeable surface layer through the liquid-permeable surface layer and is re-absorbed, part of the liquid directly seeps down to the leak-proof bottom film layer through the punctured holes or is absorbed in the absorbent core layer, achieving double-sided absorption of liquid, increasing the absorption speed, and the embossed pattern increases the user's visual perception of the absorbent article having the functions of breathability and fast absorption.

[0075] The present application also provides a manufacturing method of a breathable and fast-absorbing absorbent article, wherein the manufacturing method of the breathable and fast-absorbing absorbent article is used to prepare any one of the above-mentioned breathable and fast-absorbing absorbent articles.

In some embodiments, the absorbent core layer 103 can mix superabsorbent resin or use pulverized plant fibers and superabsorbent resin or mix plant fibers, chemical fibers and superabsorbent resin, and integrally form by non-woven process.

[0080] The absorbent core layer 103 made of the mixed material can reduce the gel effect generated by the superabsorbent resin after the superabsorbent resin absorbs the liquid, and the generated gel effect will also prevent the liquid from seeping down, affecting the secondary absorption and multiple absorptions, thereby affecting the air permeability of the absorbent core layer 103 and ensuring the air permeability of the absorbent article 100.

[0081] The material of the liquid-permeable surface layer 101 can be composed of chemical fibers, natural fibers or a mixture of chemical fibers and natural fibers. In some embodiments, the chemical fibers are made into the liquid-permeable surface layer 101 of chemical fiber non-woven fabric by hot air non-woven process. The natural fibers include cotton fibers, silk fibers, hemp fibers, bamboo fibers, etc., and are made into the natural fiber liquid-permeable surface layer 101 by hydroentangling non-woven process, or the chemical fibers and natural fibers are mixed in a certain proportion to make the liquid-permeable surface layer 101 of mixed chemical fiber non-woven fabric, and the gram weight is 15 gsm to 55 gsm, which can be 15 gsm, 18 gsm, 20 gsm, 25 gsm, 30 gsm, 32 gsm, 35.5 gsm, 40 gsm, 50 gsm, 55 gsm, etc.

[0082] The leak-proof bottom film layer 104 can use a PE (Polyethylene) film, especially including a breathable PE film. The principle that the breathable PE film is breathable but not permeable to water can be utilized to achieve a higher air permeability of the absorbent article 100.

[0084] In the liquid-permeable surface layer 101, especially in the area for skin contact, the skin contact area is reduced through a punching technique to increase breathability. The aperture size of the punched holes in the liquid-permeable surface layer 101 is between 0.3 mm and 2 mm, and can be 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, 0.7 mm, 0.9 mm, 1.0 mm, 1.5 mm, 2 mm, etc. The aperture sizes of the punched holes can be equal or unequal, and can be distributed in a matrix, circularly, or randomly, etc. In some embodiments, the aperture or density of the holes 102 in the middle area can be larger than that of the surrounding holes 102 to improve the absorption performance and breathability. The embossing technique can also be adopted to further reduce the skin contact area.

[0085] S103: Bond the absorbent core layer 103 and the leak-proof bottom film layer 104 to the surface of the liquid-permeable surface layer 101 away from the side for skin contact in sequence to form the absorbent article 100.

[0086] The liquid-permeable surface layer 101 can be a single layer or multiple layers stacked on the absorbent core layer 103 to achieve the functions of liquid diversion or absorption.

[0087] Between the layers of the absorbent object, viscous substances such as glue and hot melt adhesive can be used to bond and fix them at the edges to improve the breathability of the skin contact surface of the absorbent article 100.

[0088] Please refer to Figure 10 , Figure 10 which is a schematic flow chart of the second implementation manner of the manufacturing method of the breathable and fast-absorbing absorbent article in this application. For reference in manufacturing Figure 4 the structure of the third implementation manner of the breathable and fast-absorbing absorbent article in this application as shown, etc.

[0089] S201: Prepare the absorbent core layer 103, the liquid-permeable surface layer, and the leak-proof bottom film layer 104.

[0090] The specific content of step S201 is the same as that of the above step S201, so it will not be elaborated here.

[0091] In an optional implementation manner, S202: Perform a punching process on the absorbent core layer 103;

[0092] In an optional implementation manner, the liquid-permeable surface layer includes a first liquid-permeable surface layer 1011 and a second liquid-permeable surface layer 1012. The materials of the two liquid-permeable surface layers 101 can be the same or different, and the thicknesses can also be the same or different. They can be composed of chemical fibers, natural fibers, or a mixture of chemical fibers and natural fibers.

[0093] S203: Perform a punching process on the first liquid-permeable layer 1011 and the second liquid-permeable layer 1012 respectively to form a first hole 1021 and a second hole 1022 respectively, and bond the first liquid-permeable layer 1011 and the second liquid-permeable layer 1012.

[0094] There may be a gap or they may be in contact between the first liquid-permeable layer 1011 and the second liquid-permeable layer 1012. There may also be a contact or a gap between the second liquid-permeable layer 1012 and the absorbent core layer 103. The selection is made according to the specific production situation. In one embodiment, the structure with a gap can increase a certain air permeability.

[0095] The first liquid-permeable layer 1011 is formed with a first hole 1021 therethrough, and the second liquid-permeable layer 1012 is formed with a second hole 1022 therethrough; at least part of the position of the first hole 1021 corresponds to at least part of the position of the second hole 1022, so that part of the liquid contacts the second liquid-permeable layer 1012 through the first hole 1021, and / or contacts the absorbent core layer 103 through the first hole 1021 and the second hole 1022.

[0096] After the liquid contacts the first liquid-permeable layer 1011, part of the liquid infiltrates through the first liquid-permeable layer 1011 to the second liquid-permeable layer 1012 and is then absorbed. The first hole 1021 and the second hole 1022 may all correspond one by one, so that the liquid can be quickly guided to the absorbent core layer 103 when it contacts the absorbent article 100. In some embodiments, part of the first holes 1021 and the second holes 1022 may communicate with each other. The number of the first holes 1021 and the second holes 1022 may be the same or different. The number of the first holes 1021 may be more than the number of the second holes 1022, or the number of the first holes 1021 may be less than the number of the second holes 1022. The aperture sizes of the punched holes of the first hole 1021 and the second hole 1022 may be equal or unequal, and may be distributed in a matrix, circularly, or randomly, etc. In some embodiments, the aperture or density of the holes 102 in the middle region may be larger than that of the surrounding holes 102 to improve the absorption performance and air permeability.

[0097] The punching process is online punching and / or offline punching, and the aperture size of the punched holes of the liquid-permeable layer is 0.3 mm to 2 mm.

[0098] Among them, during online punching, when processing the material of the liquid-permeable surface layer on the manufacturing equipment of the absorbent article 100, before laminating the material of the liquid-permeable surface layer with other layers, punching treatment is performed through the punching equipment on the manufacturing equipment. Offline punching means that the material of the liquid-permeable surface layer is punched by a separate punching equipment before being set on the manufacturing equipment of the absorbent article 100, and then the liquid-permeable surface layer 101 with punched holes is set on the manufacturing equipment of the absorbent article 100 for further processing. The punching equipment can be a non-heated punching equipment or a heated punching equipment.

[0099] Both the first liquid-permeable surface layer 1011 and the second liquid-permeable surface layer 1012 can be further processed by embossing technology to reduce the skin contact area or improve breathability.

[0100] In other embodiments, it is also possible to bond the third liquid-permeable surface layer or more than three layers of liquid-permeable surface layers with holes 102 punched therein to improve the comfort or softness of the side in contact with the skin.

[0101] S204: Bond the absorbent core layer 103 and the leak-proof bottom film layer 104 to the surface of the liquid-permeable surface layer away from the side for contacting the skin in sequence to form the absorbent article 100.

[0102] In an alternative embodiment, the leak-proof bottom film layer 104 can be punched through to form micropores during preparation, and embossing is further provided on the side of the leak-proof bottom film layer 104 away from the absorbent core layer 103; the pore size of the micropores is between 10 mm and 100 mm to hinder liquid penetration and allow liquid vapor and / or air flow to pass through.

[0103] The leak-proof bottom layer of the absorbent article 100 uses a breathable PE film, so that the absorbent article 100 has a substantial breathable perception. The leak-proof bottom film 104 is made by blending PE and calcium carbonate through a blow molding or casting process, and the content of calcium carbonate is approximately between 40% and 60%, which can be 40%, 45%, 50%, 55.5%, 58%, 60%, etc. There are many through micropores in the leak-proof bottom film 104, and the pore size can be 10 mm, 15 mm, 20 mm, 20.5 mm, 30 mm, 50 mm, 70 mm, 85 mm, 90 mm, 100 mm, etc., so as to achieve the effect of waterproofing but allowing water vapor to pass through.

[0104] The air permeability of the leak-proof bottom film 104 is between 500 and 3000 g / m 2 ·24h, which can be 500 g / m 2 ·24h, 525 g / m 2 ·24h, 550 g / m 2 ·24h, 580 g / m 2 ·24h, 400 g / m 2 ·24h, 500 g / m 2· 24h, 600 g / m 2 · 24h, 700.5 g / m 2 · 24h, 1000 g / m 2 · 24h, 2000 g / m 2 · 24h, 3000 g / m 2 · 24h etc. The grammage of the leak-proof bottom film 104 material is between 25 gsm and 45 gsm, and can be 25 gsm, 28 gsm, 30 gsm, 35 gsm, 40 gsm, 42 gsm, 43.5 gsm, 45 gsm, etc.

[0105] In some embodiments, the exposed side of the leak-proof bottom film 104 can have dot embossing or other embossing indicating breathability, so that users can visually perceive the high breathability of the material.

[0106] After absorbing liquid, since there is no material in the pores, it will not hinder the air circulation after the absorbent core absorbs the liquid, and keeps the absorbent article 100 having good breathability.

[0107] Please refer to Figure 11 , Figure 11 which is a schematic flow chart of the third implementation manner of the manufacturing method of the breathable and quick-absorbing absorbent article of the present application. For manufacturing reference Figure 5 the structure of the fourth implementation manner of the breathable and quick-absorbing absorbent article of the present application shown, etc.

[0108] S301: Prepare the absorbent core layer 103, the liquid-permeable surface layer and the leak-proof bottom film layer 104.

[0109] The specific content of step S301 is the same as that of step S201 above, so it will not be elaborated here.

[0110] In an alternative embodiment, S302: Prepare the liquid-repellent surface layer 105 and perform punching and / or process treatment on the liquid-repellent surface layer 105.

[0111] The liquid-repellent surface layer 105 is arranged at the peripheral edge of the absorbent article 100 to prevent liquid from leaking out through the side before being absorbed.

[0112] The material of the liquid-repellent surface layer 105 is mainly composed of chemical fibers. The chemical fibers are made into thermally weathered chemical fiber non-woven fabric through hot air non-woven process, or can be made into spunmelt chemical fiber non-woven fabric through spunmelt non-woven process. Among them, the punched thermally weathered chemical fiber non-woven fabric can also be realized by the above two methods of online punching and offline punching. The spunbond non-woven fabric is adhesively bonded to the upper and lower sides of the meltblown cloth through evenly distributed dots, and can be a three-layer, four-layer, five-layer or six-layer structure with spunbond non-woven fabric on the upper and lower surfaces and a combination of meltblown + spunbond non-woven fabric in the middle.

[0113] The pore size of the punched thermally weathered fiber non-woven fabric of the water-repellent layer 105 is between 0.3 mm and 2 mm, and can be 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, 0.7 mm, 0.9 mm, 1.0 mm, 1.5 mm, 2 mm.

[0114] The gram weight of the punched thermally weathered fiber non-woven fabric material of the water-repellent layer 105 is between 15 gsm and 55 gsm, and can be 15 gsm, 18 gsm, 20 gsm, 25 gsm, 30 gsm, 32 gsm, 35.5 gsm, 40 gsm, 50 gsm, 55 gsm, etc. The gram weight of the single-layer spunbond non-woven fabric material is between 3 gsm and 15 gsm, and can be 3 gsm, 3.2 gsm, 3.55 gsm, 4 gsm, 5 gsm, 8 gsm, 10 gsm, 15 gsm, etc. The gram weight of the meltblown non-woven fabric material is between 3 gsm and 15 gsm, and can be 3 gsm, 3.2 gsm, 3.55 gsm, 4 gsm, 5 gsm, 8 gsm, 10 gsm, 15 gsm, etc.

[0115] The diameter of the spunbond pressing points or embossed patterns on the surface of the spunmelted fiber non-woven fabric of the water-repellent layer 105 is between 0.45 and 1.5 mm, and can be 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, 0.7 mm, 0.9 mm, 1.0 mm, 1.5 mm.

[0116] Through the punching or embossing settings, the air permeability of the water-repellent layer 105 in the area in contact with the skin is improved, and the air in the middle will also flow outward, further enhancing the air circulation in the skin contact area of the middle area, effectively improving the air permeability of the entire absorbent article 100.

[0117] The water-repellent layer 105 is disposed on the side of the absorbent article 100 for contacting the skin, covers part of the liquid-permeable layer, and is adhered to the leak-proof bottom film layer 104 to fix and / or wrap at least part of the liquid-permeable layer and the absorbent core layer 103.

[0118] S303: Perform a punching process on the first liquid-permeable layer 1011 and the second liquid-permeable layer 1012 respectively to form a first hole 1021 and a second hole 1022, and bond the first liquid-permeable layer 1011 and the second liquid-permeable layer 1012.

[0119] The specific content of step S303 is the same as that of step S203 above, so it will not be elaborated here.

[0120] S304: Bond the water-repellent layer 105 to the surface of one side of the liquid-permeable layer.

[0121] The water-repellent surface layer 105 of the part is bent inward and bonded in two layers to improve the adhesion of the water-repellent surface layer 105 to each layer and effectively prevent liquid from penetrating from the side of the absorbent article 100.

[0122] In an alternative embodiment, S305: Bond the absorbent core layer 103 to the other side surface of the liquid-permeable surface layer. The liquid-permeable surface layer and the absorbent core layer 103 are bonded to form a bonded structure (not labeled in the figure), and a through-hole punching process is performed to penetrate the bonded structure.

[0123] The size of the through-hole punching aperture of the bonded structure is 1 mm to 1.8 mm.

[0124] After the absorbent article 100 is integrally formed by laminating the liquid-permeable surface layer 101, the second liquid-permeable surface layer 1012 and the absorbent core, punching is performed to penetrate them. The three layers can be punched through by online punching or offline punching. Online punching is to perform punching on the composite material on the absorbent article 100 manufacturing equipment after the liquid-permeable surface layer, the second liquid-permeable surface layer 1012 and the absorbent core are laminated, and then further processing is carried out by setting the absorbent article 100 manufacturing equipment. Offline punching is to punch the liquid-permeable surface layer, the second liquid-permeable surface layer 1012 and the absorbent core, and then before setting the composite material on the absorbent article 100 manufacturing equipment, punch the surface layer through a separate punching device, and then set the punched material on the absorbent article 100 manufacturing equipment for use. The punching device can be a non-heated punching device or a heated punching device. The aperture of the holes punched in the composite material is between 1 mm and 1.8 mm, such as 1 mm, 1.1 mm, 1.2 mm, 1.35 mm, 1.4 mm, 1.5 mm, 1.8 mm, etc. After the composite material is punched, when absorbing liquid, since there is no material in the pores, it will not hinder the air circulation after the absorbent core absorbs the liquid, and keep the absorbent article 100 having good air permeability.

[0125] S306: Bond the leak-proof bottom film layer 104 to the surface of the liquid-permeable surface layer away from the side for contacting the skin. The water-repellent surface layer 105 is bonded to the leak-proof bottom film layer 104 to fix and / or wrap at least part of the liquid-permeable surface layer and the absorbent core layer 103, forming the absorbent article 100.

[0126] Please refer to Figure 12 , Figure 12 is a schematic flow chart of the fourth embodiment of the manufacturing method of the breathable and fast-absorbing absorbent article of the present application. For reference in manufacturing Figure 6 the structure shown in the fifth embodiment of the breathable and fast-absorbing absorbent article of the present application, etc.

[0127] S401: Prepare the absorbent core layer 103, the liquid-permeable surface layer and the leak-proof bottom film layer 104.

[0128] S402: Prepare a water-repellent surface layer and perform punching and / or processing on the water-repellent surface layer.

[0129] In an alternative embodiment, the water-repellent surface layer includes a wrapped water-repellent surface layer 1051 and two side water-repellent surface layers 1052; the size of the punching aperture is 0.3 mm to 2 mm.

[0130] S403: Perform punching process on the first liquid-permeable surface layer 1011 and the second liquid-permeable surface layer 1012 respectively to form a first hole 1021 and a second hole 1022, and bond the first liquid-permeable surface layer 1011 and the second liquid-permeable surface layer 1012.

[0131] The specific contents of steps S401, S402 and S403 are the same as those of steps S301, S302 and S303 above, so they will not be elaborated here.

[0132] S404: Bond the wrapped water-repellent surface layer 1051 to the liquid-permeable surface layer; after the absorbent core layer 103 is bonded to the other side surface of the liquid-permeable surface layer, the other side of the wrapped water-repellent surface layer 1051 wraps the absorbent core layer 103 to form a composite structure.

[0133] Part of the wrapped water-repellent surface layer 1051 and part of the water-repellent surface layer 105 are bent or folded inward into two layers and bonded to wrap the composite structure, which can improve the adhesion between the water-repellent surface layer 105 and each layer and effectively prevent liquid from penetrating from the side of the absorbent article 100.

[0134] S405: Bond the absorbent core layer 103 to the other side surface of the liquid-permeable surface layer, and the liquid-permeable surface layer and the absorbent core are bonded to form a bonded structure, and perform a punching process to penetrate the bonded structure.

[0135] The specific content of step S405 is the same as that of step S406 above, so it will not be elaborated here.

[0136] S406: Partially paste and arrange the two side water-repellent surface layers 1052 between the composite structure and the leak-proof bottom film layer 104 to fix the composite structure, and bond the two side water-repellent surface layers 1052 and the leak-proof bottom film layer 104 to fix and / or wrap at least part of the liquid-permeable surface layer and the absorbent core layer 103 to form an absorbent article 100.

[0137] The thickness of the wrapped water-repellent surface layer 1051 and the two side water-repellent surface layers 1052 can be the same or different, and the aperture or density of punching can be the same or different. The formed composite structure can prevent liquid from penetrating outside the absorbent object before being absorbed. It can also further strengthen the fixing degree between each layer.

[0138] The layers of the absorbent object can be adhesively fixed at the edges with viscous substances such as glue and hot melt adhesive to improve the air permeability of the skin contact surface of the absorbent article 100.

[0139] In the above manner, an absorbent article with air permeability and quick absorption and a manufacturing method of the absorbent article with air permeability and quick absorption are provided. By punching holes in the liquid-permeable layer for skin contact in the middle area of the absorbent article, punching and embossing the water-repellent layer material of the skin contact layer in the two side areas, puncturing the whole absorbent article or using a dot-permeable PE film for the leak-proof bottom film layer, the air permeability during use is improved. Puncturing the whole absorbent article ensures that air holes are retained after liquid absorption, reducing the decrease in air permeability after liquid absorption. Part of the liquid seeps down through the liquid-permeable layer to the second liquid-permeable layer for absorption, and part of the liquid directly seeps down through the punctured holes to the leak-proof bottom film layer or is absorbed in the absorbent core layer, achieving double-sided absorption of the liquid and increasing the absorption speed. The embossed pattern increases the user's visual perception of the absorbent article having the function of air permeability and quick absorption.
