[0031] The following will combine with the accompanying drawings of the specification to elaborate in detail on the solutions of the embodiments of the present application.

[0032] In the following description, for the purpose of illustration rather than limitation, the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0033] The present application provides a waist-type absorbent article. Please refer to Figure 1 , Figure 1 which is a schematic cross-sectional exploded view of the first implementation mode of the waist-type absorbent article of the present application. The waist-type absorbent article 10 includes an absorbent layer 11 and a waist layer 260.

[0034] Among them, the absorbent layer 11 is used to fit against the human body, etc., so as to absorb liquid. The absorbent layer 11 is arranged on one side of the waist layer 260. The part of the waist layer 260 connected to the absorbent layer 11 does not fit against the human body, and only the part without the absorbent layer 11 fits against the human body layer. Therefore, the absorbent layer 11 can be regarded as the inner layer, and the waist layer 260 can be regarded as the outer layer. The function of the waist layer 260 is to cooperate with the human body, etc. for wearing when the waist-type absorbent article 10 is used, so as to fix the absorbent layer 11 at a preset position. In the present application, the waist layer 260 includes fabric and bamboo charcoal material doped into the fabric. And because the bamboo charcoal material is doped into the fabric, it will show a black color.

[0035] The addition of the bamboo charcoal material enables the waist layer 260 to have certain antibacterial and deodorizing effects. And during use, since the absorbent layer 11 in the present application is arranged inside the waist layer 260, the waist layer 260 will cooperate with the skin, etc. to enclose the absorbent layer 11, so that the waist-type absorbent article 10 can have good antibacterial and deodorizing effects. In addition, the black waist layer 260 can avoid the embarrassment of others seeing the absorbent liquid state when the user discards the waist-type absorbent article 10 in the trash can after use. At the same time, black as the color of the waist layer 260 will be more fashionable and sexy, and to a certain extent, it enhances the emotional value before the user uses it.

[0036] Preferably, the waistband layer 260 further includes polypropylene and / or polyester material, and bamboo charcoal material is doped into the polypropylene and / or polyester material to make the waistband layer 260 appear black. Polypropylene is the main material for making non-woven fabrics, and polyester material such as polyester fiber is also a commonly used fabric making material. In this application, the waistband layer 260 is preferably made of non-woven fabric or polyester fiber fabric. The fabric made of polypropylene material or polyester material has the characteristics of being non-toxic, colorless, odorless, etc. It is safe and reliable, and can also be dyed black by bamboo charcoal material, with the characteristic of being easy to color.

[0037] To make the waistband layer 260 more durable, the waistband layer 260 may further include one or more of a first softening material, an antioxidant material, an anti-pilling material, and a flame retardant material. The first softening material can be achieved, for example, by adding a softening masterbatch during the production process of the waistband layer 260. The antioxidant material can be achieved by adding an antioxidant during the production process of the waistband layer 260. The anti-pilling material can be achieved by adding an anti-pilling agent during the production process of the waistband layer 260. The flame retardant material can be achieved by adding a flame retardant during the production process of the waistband layer 260. In addition, those skilled in the art can also add other materials to the waistband layer 260 through techniques well-known in the art, which will not be elaborated here. During production, various materials can be added according to needs, such as only adding a softening material and an anti-pilling material, etc., and adjusted as needed, which will not be elaborated here.

[0038] In addition, since the waist-type absorbent article 10 is mostly used in contact with the skin during use, the waistband layer 260 further includes a second softening material to improve the softness of the waistband layer 260. And in order to prevent the bamboo charcoal material from causing skin discomfort, the particle size of the bamboo charcoal material is not greater than 100 nanometers.

[0039] Please continue to refer to Figure 1, wherein the absorbent layer 11 includes a liquid-repellent surface layer 210, a first liquid-permeable layer 220, a second liquid-permeable layer 240, a core absorbent layer 250, and a leakage-proof bottom layer 230. The liquid-repellent surface layer 210 is disposed on a part of the top surface, side surface, and part of the bottom surface of the first liquid-permeable layer 220. The first liquid-permeable layer 240 is surrounded by the liquid-repellent surface layer 210 and forms a receiving space with an opening structure at the bottom surface. The second liquid-permeable layer 240 and the core absorbent layer 250 are disposed in the receiving space. Wherein the second liquid-permeable layer 240 is closer to the top surface of the first liquid-permeable layer 220 than the core absorbent layer 250, and the core absorbent layer 250 is closer to the bottom surface of the first liquid-permeable layer 220 than the second liquid-permeable layer 240. The part of the liquid-repellent surface layer 210 located at the bottom surface of the first liquid-permeable layer 220 is connected to the leakage-proof bottom layer 230. One side of the leakage-proof bottom layer 230 away from the first liquid-permeable layer 220 is connected to one side of the waistband layer 260. The first liquid-permeable layer 220 and the second liquid-permeable layer 240 are used for liquid absorption and penetration. After the first liquid-permeable layer 220 comes into contact with the liquid, it will absorb the liquid and allow the liquid to penetrate in the first liquid-permeable layer 220. The second liquid-permeable layer 240 will receive the liquid absorbed and penetrated by the top surface of the first liquid-permeable layer 220. The liquid-repellent surface layer 210 and the leakage-proof bottom layer 230 are used to isolate the penetration of the liquid and prevent the liquid from flowing out of the first liquid-permeable layer 220. The main function of the absorbent core layer 250 is to absorb and store the liquid that penetrates into the absorbent core layer 250. The absorbent layer 11 can also use the absorbent layer 11 of any existing absorbent article as long as it can absorb and store the liquid. In addition, those skilled in the art can supplement other components to the absorbent layer 11 according to the prior art, and the present application does not make any limitations here.

[0040] Please refer to Figure 2 , Figure 2 is a front view schematic diagram of the second embodiment of the waist-type absorbent article of the present application. In this embodiment, the waistband layer 22 in the waist-type absorbent article 20 is annular. That is to say, the waistband layer 22 is a continuous structure, and the structure of the waist-type absorbent article 20 is similar to that of existing articles such as underwear and pull-ups.

[0041] This kind of structure is relatively simple and can be worn or taken off conveniently and quickly.

[0042] Please refer to Figure 3 , Figure 3Front view schematic diagram of the third embodiment of the waist-type absorbent article of the present application. In this embodiment, the waist layer 32 in the waist-type absorbent article 30 is in the shape of a sheet, and connection structures 321 are provided at different positions for connecting the waist layer 32 into a ring shape by cooperation. The different positions can be the two side edges of the waist layer 32. The connection structure 321 can be a magic tape, a waist sticker, a hook structure, a button structure, a zipper structure, etc., as long as it can connect the two sides of the waist layer 32. This structure has a wide adjustment range and is suitable for users in the stage of body shape change or users who are not very clear about the size requirements.

[0043] By the above method, adding bamboo charcoal material to a larger-area waist layer can increase the area of antibacterial, and through the adsorption function of the bamboo charcoal material, the emission of the liquid smell absorbed by the absorbent article can be reduced, and the peculiar smell generated when the absorbent article is used can be better reduced.

[0044] The present application also provides a manufacturing method of a waist-type absorbent article. Please refer to Figure 4 , Figure 4 Flow chart of the first embodiment of the manufacturing method of the waist-type absorbent article of the present application. In this embodiment, the manufacturing method of the waist-type absorbent article includes:

[0045] S11: Obtain an absorbent layer. The absorbent layer can be obtained by manufacturing or directly using a finished product.

[0046] S12: Obtain a waist layer. The waist layer can be obtained by manufacturing or directly using a finished product. Among them, the order of S11 and S12 is not limited. S11 can be carried out first, or S12 can be carried out first, or S11 and S12 can be carried out simultaneously.

[0047] S13: Thermally fuse the absorbent layer to one side of the waist layer. Among them, bamboo charcoal material is doped in the waist layer. Due to the doping of bamboo charcoal material in the waist layer, the produced waist-type absorbent article can also achieve the above effects.

[0048] Please refer to Figure 5 , Figure 5 For Figure 4 Sub-flow chart of the first embodiment of S12 in

[0049] S121: Obtain polypropylene. Polypropylene can be obtained by manufacturing or directly using a finished product.

[0050] S122: Add bamboo charcoal material to polypropylene and mix evenly to form a mixture. The bamboo charcoal material can be bamboo charcoal particles, bamboo charcoal powder, etc. The particle size of the bamboo charcoal material is preferably not more than 100 nanometers.

[0051] S123: Melt-extrude, spin, form a web, thermally bond, and post-process the mixture to form a waist circumference layer.

[0052] In some embodiments, the step of adding bamboo charcoal material to polypropylene and mixing evenly to form a mixture may further include: adding bamboo charcoal material to polypropylene and adding one or more of a first softening material, an antioxidant material, and a flame retardant material to form a mixture.

[0053] Please refer to Figure 6 , Figure 6 is Figure 4 a sub-flowchart of the second embodiment of S12 in

[0054] S21: Obtain polypropylene. Polypropylene can be obtained by manufacturing or directly using a finished product.

[0055] S22: Feed in. The main raw material is polypropylene, and at the same time, additives such as bamboo charcoal particle powder, softening masterbatch, antioxidant, anti-pilling agent, and flame retardant are added. After mixing the above raw materials evenly, they are transported to a screw extruder through a vacuum system for melt-extrusion to form a hot melt.

[0056] S23: Melt spinning. The melted hot melt is extruded through a spinneret to form a primary fiber web with a diameter of 0.3 - 0.8 mm. The primary fiber web is cooled to 20 - 10 °C in the air, and the humidity is controlled at 20 - 30% to ensure the morphological stability of the fibers. Preferably, the above materials are melt-spun simultaneously through three parallel nozzles.

[0057] S24: Web forming. The primary fiber web is drawn through a drawing device, and the drawing rate is 2000 - 5000 m / min. The above three parallel nozzles are overlapped and tiled to finally form a composite fiber web. The drawn composite fiber web is formed into a uniform non-woven fiber web through air current fiber splitting and web forming.

[0058] S25: Thermal bonding. The formed fiber web is sent to a hot press for thermal bonding to enhance the bonding force between the fibers. The temperature and pressure of the hot press need to be strictly controlled to ensure the strength and softness of the non-woven fabric.

[0059] S26: Post-processing. Post-processing includes steps such as cutting, winding, drawing, and coating, and finally a black super-soft spunbond non-woven waist material, that is, the waist circumference layer, is obtained.

[0060] The above steps can also be replaced by conventional techniques in the art for manufacturing the waist circumference layer. For example, polypropylene can be replaced by polyester material, and the present application does not make any limitations.

[0061] In some embodiments, to make the waist circumference layer softer, the steps of obtaining the waist circumference layer further include: softening the waist circumference layer with a second softening material. Preferably, the second softening material is a cream solvent. Cream solvents are generally used for softening paper and are not used on non-woven fabrics and other cloth materials. However, when cream solvents are applied to non-woven fabrics, the non-woven fabrics will be further softened, increasing their softness. Specifically, a cream solvent can be sprayed onto the waist circumference layer formed in S26 through a spraying device, and the addition amount is between 10% and 35%. Then, drying treatment is carried out, the drying temperature is 70°C, and the moisture regain rate after drying is controlled between 1% and 5%.

[0062] By softening the waist circumference layer in this way for the second time, the softness of the waist circumference layer can be increased, making it fit the skin better and reducing skin damage during wearing.

[0063] Please refer to Figure 7 , Figure 7 , which is a flowchart of an embodiment of the manufacturing method of the cream solvent used in the manufacturing method of the waist-type absorbent article of the present application. The manufacturing method of the above cream solvent may include the following steps:

[0064] S31: Obtain an aqueous phase material and an oil phase material. The aqueous phase material consists of water, an emulsifier, a preservative, and other active ingredients. Among them, the emulsifier is, for example, stearic acid, PEG-100 stearate, etc., the preservative is, for example, methyl paraben, etc., and other active ingredients are, for example, vitamin E, antioxidant, etc. The oil phase material includes oil-soluble components such as mineral oil, stearate, and cetyl alcohol.

[0065] S32: Dissolve and mix evenly the aqueous phase material and the oil phase material obtained in S31 at a temperature of 75°C to 80°C. S31 and S32 can be carried out in combination. For example, first obtain the aqueous phase material and process the aqueous phase material according to S32; then obtain the oil phase material and process the oil phase material according to S32. Or, first obtain the oil phase material and process the oil phase material according to S32; then obtain the aqueous phase material and process the aqueous phase material according to S32. Or, obtain the aqueous phase material and the oil phase material simultaneously, and then process the two materials simultaneously or successively according to S32.

[0066] S33: Mixing and emulsifying. Slowly add the aqueous phase material processed according to S32 to the oil phase material processed according to S32 while continuously stirring to form an emulsion. This process is called emulsification. The emulsifier plays a key role in this process to help form a stable emulsion structure. During the emulsification process, the temperature and stirring speed need to be controlled to ensure the uniformity and stability of the emulsion. Generally, the emulsification temperature gradually decreases from a high temperature to room temperature.

[0067] S34: Cooling and pH adjustment. After emulsification is completed, cool the mixture to room temperature. During this process, appropriate amounts of preservatives and fragrances may need to be added to ensure the stability and sensory quality of the product. Finally, adjust the pH value of the mixture to an appropriate range by adjusting the acidic and alkaline substances in the formula, such as sodium citrate or sodium hydroxide, to ensure the best performance and stability of the product. The pH value of the product is usually 5 - 7.

[0068] S35: Filtration. The prepared cream solvent needs to be filtered to remove possible particles or impurities, ensuring the purity and transparency of the product, thereby obtaining the above-mentioned sprayed cream solvent.

[0069] Alternatively, those skilled in the art can also use other cream solvents that can be used for softening treatment. This is a preferred embodiment and is not limiting.
