AI Technical Summary
The existing diaper products have insufficient comfort in terms of the side panel structure. In particular, the non-woven fabric of the double-layer side panel structure is too stiff after wrapping the elastic band, which can easily scratch the baby's skin and affect the comfort of wearing the diaper.
The structure features a liquid-permeable top layer, an absorbent core layer, and a liquid-impermeable bottom layer. The non-woven fabric on the side is folded twice to form multiple hollow channels, which wrap around the rubber band on the side to form a flexible air-feeling channel structure. This reduces the contact sensitivity between the rubber band and the skin and improves the ability to block body fluids.
It improves the comfort of wearing diapers, reduces the risk of leakage, and maintains good side leakage prevention. The soft side panels and multi-layer structure enhance the ability to block body fluids.

Abstract
Description
Technical Field
[0001] This invention relates to the field of disposable hygiene products, specifically to an air-feeling diaper with side panels and its manufacturing process. Background Technology
[0002] The side panels of existing diaper products are mainly categorized by their shape during use: folded outwards or not folded outwards. Structurally, they are further divided into single-layer and double-layer. The most basic structure involves wrapping an elastic side panel between two layers of non-woven fabric. After the non-woven fabric wraps the elastic panel, it is laminated to the diaper body. Currently, the single-layer side panel structure cannot achieve the same or near-equivalent liquid barrier performance as the double-layer side panel. Therefore, many diaper products on the market have begun to adopt a double-layer side panel structure. The existing double-layer side panel diaper product structure is illustrated in Chinese Patent CN 219983221. As shown in Figure U, a double-layer three-dimensional partition diaper with core-guided flow includes a diaper body and three-dimensional partitions disposed on both sides of the diaper body in the width direction. The diaper body includes a flow-guiding surface layer, a core, and a bottom layer disposed from the inside out. The three-dimensional partitions include an outer three-dimensional partition and an inner three-dimensional partition. The inner three-dimensional partition includes a hydrophilic covering fabric and a first elastic band. The hydrophilic covering fabric is disposed between the core and the bottom layer, and the hydrophilic covering fabric is folded inward on both sides along the width direction of the core. The first elastic band is disposed between the folded positions of the hydrophilic covering fabric. An outer three-dimensional partition is provided on the outside of the inner three-dimensional partition, and a second elastic band is provided inside the outer three-dimensional partition.
[0003] This structure uses two closely spaced outer and inner three-dimensional partitions to form a double-layer anti-leakage design. From the perspective of a single partition structure, it still adopts the traditional form of partition rubber wrapped between two layers of non-woven fabric.
[0004] In this design, the space formed by the non-woven fabric wrapping the elastic band is not combined with other soft materials. In addition, the non-woven fabric has a low basis weight, so the elastic band feels obvious when you touch it. The entire elastic band feels hard and the elastic band feels obvious. When the baby's delicate skin rubs against the elastic band, it can easily cause redness or even scratches, reducing the comfort of wearing the diaper and affecting consumers' desire to buy. Summary of the Invention
[0005] Therefore, the present invention provides an air-feeling side-part diaper and its manufacturing process, which solves the problem of insufficient comfort of the side-part structure in existing diaper products.
[0006] To achieve the above objectives, the present invention is implemented through the following technical solution:
[0007] An air-feeling diaper with side panels includes a liquid-permeable top layer, an absorbent core layer, and a liquid-impermeable bottom layer stacked from top to bottom. The upper surface of the liquid-permeable top layer is symmetrically provided with leak-proof side panels. Each leak-proof side panel includes a side panel elastic and a side panel non-woven fabric that is folded twice to wrap the side panel elastic. The side panel non-woven fabric is divided into a first folded part and a base part by a first fold, forming a first fold line that separates the first folded part and the base part. The side panel elastic is adhered to the base part by adhesive and covered by the first folded part. The free end of the first folded part is bonded to the base part to form a first hollow channel covering the side panel elastic.
[0008] The first fold portion and the base are folded a second time to form a second fold portion and a second fold line. The first hollow channel is separated by the second fold line to form two second hollow channels. The free end of the second fold portion is bonded to the non-woven fabric of the side to form a third hollow channel located between the two second hollow channels.
[0009] Preferably, during a single fold, the minimum distance between the first fold line and the spacer rubber band is not less than 10 mm.
[0010] Preferably, during the second fold, the maximum distance between the second fold line and the spacer rubber strip is not less than 5 mm.

[0056] By adopting the aforementioned technical solution, the beneficial effects of the present invention are:
[0057] The diaper product shown in this technical solution has a significantly different structure in its leak-proof side panels compared to traditional side panels. It features a double-folded design that fully covers the elastic band of the side panel. The double folding of a single layer of non-woven fabric creates multiple hollow channels outside the elastic band. During use, as the elastic band contracts, these hollow channels form multiple flexible, airy channels, creating a "bubble side panel." This structure greatly reduces the perceived softness of the elastic band when in contact with the consumer, as is common in traditional side panel designs, resulting in greater comfort. Furthermore, the multi-layered structure also improves the barrier against bodily fluids, enhancing leak prevention and significantly reducing the risk of leakage.
[0058] During production, the position of the spacer rubber and the glue application are adjusted to form a situation where glue is applied at the sealing point and not applied to the hollow channel, so that the non-woven fabric at the spacer can form folds as the spacer rubber shrinks. With this design, only a folding mechanism and a related sealing glue gun need to be added to the production equipment. The equipment modification is small, highly feasible, and practical.

[0063] The following will describe in detail the implementation of the present invention with reference to specific embodiments, so that the process of how the present invention uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Example 1
[0064] refer to Figure 1 An air-feeling diaper with side panels includes a liquid-permeable top layer, an absorbent core layer, and a liquid-impermeable bottom layer stacked from top to bottom. The upper surface of the liquid-permeable top layer is symmetrically provided with leak-proof side panels. Each leak-proof side panel includes a side panel elastic 2 (here, there are two side panel elastic 2s, which are arranged in parallel) and a side panel non-woven fabric 1 that is folded twice to wrap the side panel elastic 2. The side panel non-woven fabric 1 is divided into a first folded part 11 and a base part 12 by a first fold, and a first fold line 111 is formed to separate the first folded part 11 and the base part 12. The side panel elastic 2 is adhered to the base part 12 by adhesive and is covered by the first folded part 11. The free end of the first folded part 11 is bonded to the base part 12 to form a first hollow channel 1a covering the side panel elastic 2.
[0065] The first fold 11 and the base 12 are folded a second time to form a second fold 13 and a second fold line 131. The first hollow channel 1a is separated by the second fold line 131 to form two second hollow channels 1b. The free end of the second fold 13 is bonded to the side non-woven fabric 1 to form a third hollow channel 1c located between the two second hollow channels 1b. The diaper product shown in this technical solution has a significantly different structure in its leak-proof side panels compared to traditional side panels. It is folded twice to fully cover the side panel elastic 2. The double folding of the single-layer non-woven side panel fabric 1 creates multiple hollow channels outside the side panel elastic 2. During use, as the side panel elastic 2 shrinks, multiple flexible, airy channels are formed at the locations of these hollow channels, creating a "bubble side panel." This structure greatly reduces the perceived contact between the side panel elastic 2 and the consumer, improving the softness of the side panel and making it more comfortable to wear. Furthermore, the multi-layer structure also improves the barrier against bodily fluids, enhancing the leak-proof function and significantly reducing the risk of leakage.
[0066] The following process is used in the production of an air-feel side-part diaper: The process includes the following steps:
[0067] 1. Preparation of a liquid-permeable surface layer;
[0068] II. Preparation of the absorber core layer;
[0069] III. Preparation of an impermeable liquid bottom layer (Steps one, two and three all use conventional processes and techniques, which will not be described in detail here).
[0070] IV. Preparation of leak-proof partitions;
[0071] V. Stack and fix the products from steps one, two, and three together. Simultaneously, symmetrically place the leak-proof partition obtained in step four on the impermeable bottom layer on both sides of the absorbent core. Then, perform arc-shaped edge cutting and slit to form individual absorbent items. Step four includes:
[0072] a. Take a water-repellent flexible material as the non-woven fabric 1, apply adhesive to its surface and fix the rubber strip 2 at the adhesive application position;
[0073] b. Fold the non-woven fabric 1 of the side partition into a double-layer structure to wrap the side partition rubber 2, and apply adhesive to the ends of the folded non-woven fabric 1 to seal it.
[0074] c. Fold the non-woven fabric 1 of the side partition twice to form a stacked four-layer structure, and apply adhesive to the ends of the folded non-woven fabric 1 to seal it, thereby obtaining a single leak-proof side partition.
[0075] d. Repeat steps a to c to obtain another leak-proof barrier. After obtaining two leak-proof barriers, apply adhesive to their longitudinal front and rear ends. After applying the adhesive, laminate them with the liquid-permeable surface layer, absorbent core layer, impermeable bottom layer, and other related conventional structures.
[0076] During production, it is important to note that during the first fold, the minimum distance L1 between the first fold line 111 and the spacer rubber 2 is not less than 10 mm; this ensures sufficient space for the second fold to form the second fold 13, and also ensures that the edge of the second fold 13 extends beyond the two spacer rubber 2.
[0077] Meanwhile, during the second fold, the maximum distance L2 between the second fold line 131 and the spacer rubber 2 is not less than 5 mm. This size design is to ensure that the second hollow channel 1b has sufficient longitudinal space under the premise of meeting production conditions, with 5 mm as the bottom line, to ensure that the three-dimensional space structure of the "bubble spacer" is large enough. Example 2
[0078] refer to Figure 2 Compared with Embodiment 1, another side-blocking structure based on the same principle is shown, specifically an air-feel side-blocking diaper, including a liquid-permeable top layer, an absorbent core layer, and a liquid-impermeable bottom layer stacked from top to bottom. The upper surface of the liquid-permeable top layer is symmetrically provided with leak-proof side-blocking. Each leak-proof side-blocking includes a side-blocking elastic 2 and a side-blocking non-woven fabric 1 that is folded twice to wrap the side-blocking elastic 2. The side-blocking non-woven fabric 1 is divided into a first folded part 11 and a base part 12 by a first fold, and a first fold line 111 is formed to separate the first folded part 11 and the base part 12. The free end of the first folded part 11 is bonded to the base part 12 to form a first hollow channel 1a covering the side-blocking elastic 2. The side-blocking elastic 2 is adhered to the surface of the first folded part 11 by adhesive and is located outside the first hollow channel 1a.
[0079] The first fold 11 and the base 12 are folded a second time to form a second fold 13 and a second fold line 131. The first hollow channel 1a is separated by the second fold line 131 to form two second hollow channels 1b. The second fold 13 covers the spacer rubber 2. The free end of the second fold 13 is bonded to the spacer nonwoven fabric 1 to form a third hollow channel 1c located between the two second hollow channels 1b. The spacer rubber 2 is located in the third hollow channel 1c.
[0080] Compared to the structure shown in Embodiment 1, this structure has the spacer rubber 2 located in the third hollow channel 1c, which is closer to the center of the leak-proof spacer cross-section. After the spacer rubber 2 shrinks, the resulting "bubble spacer" structure is more uniform. However, it places greater demands on the gluing process for the second fold to prevent the seal from coming undone after the second fold. But in terms of the product, it has the same or better comfort.
[0081] The following process is used in the production of an air-feel side-part diaper: The process includes the following steps:
[0082] 1. Preparation of a liquid-permeable surface layer;
[0083] II. Preparation of the absorber core layer;
[0084] III. Preparation of an impermeable liquid bottom layer;
[0085] IV. Preparation of leak-proof partitions;
[0086] V. Stack and fix the products from steps one, two, and three together. Simultaneously, symmetrically place the leak-proof partition obtained in step four on the impermeable bottom layer on both sides of the absorbent core. Then, perform arc-shaped edge cutting and slit to form individual absorbent items. Step four includes:
[0087] a. Take a water-repellent flexible material as the side-separating non-woven fabric 1, fold the side-separating non-woven fabric 1 once to form a double-layered structure, and apply adhesive to the ends of the folded side-separating non-woven fabric 1 to seal it.
[0088] b. Apply adhesive to the surface of the double-layered nonwoven fabric 1 and fix the rubber strip 2 at the adhesive application position;
[0089] c. Fold the non-woven fabric 1 of the side partition twice to form a stacked four-layer structure, and apply adhesive to the ends of the folded non-woven fabric 1 to seal it, thereby obtaining a single leak-proof side partition.
[0090] d. Repeat steps a to c to obtain another leak-proof partition.
[0091] During production, it is important to note that during the first fold, the minimum distance L1 between the first fold line 111 and the spacer rubber 2 is not less than 10 mm; this ensures sufficient space for the second fold to form the second fold 13, and also ensures that the edge of the second fold 13 extends beyond the two spacer rubber 2.
[0092] Meanwhile, during the second fold, the maximum distance L2 between the second fold line 131 and the spacer rubber 2 is not less than 5 mm. This size design is to ensure that the second hollow channel 1b has sufficient longitudinal space under the premise of meeting production conditions, with 5 mm as the bottom line, to ensure that the three-dimensional space structure of the "bubble spacer" is large enough.
[0093] It should be noted that both of the above structures can be produced using the same set of leak-proof side panels (i.e., the same single diaper product). A single piece of wide non-woven fabric 1 is used for the side panels, with both edges folded simultaneously before being cut and shaped. Figure 3 As shown, (cut by the cutting line d) is the forming and folding form of the leak-proof partition shown in Embodiment 1 and Embodiment 2. In this form, the layout length of the production line can be greatly shortened, saving space and increasing the integration of the equipment.
[0094] Although the invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the invention without departing from the spirit and scope of the invention as defined in the appended claims, all of which shall be within the scope of protection of the invention.

Then, perform arc-shaped edge cutting and slit to form individual absorbent items. Step four includes: a. Take a water-repellent flexible material as the side-separating non-woven fabric (1), fold the side-separating non-woven fabric (1) once to form a double-layer structure, and apply adhesive to the ends of the folded side-separating non-woven fabric (1) to seal it. b. Apply adhesive to the surface of the double-layered nonwoven fabric with side septum (1) and fix the side septum rubber (2) at the adhesive application position. c. Fold the non-woven fabric (1) of the side panel twice to form a stacked four-layer structure, and apply adhesive to the ends of the folded non-woven fabric (1) of the side panel to seal it, thereby obtaining a single leak-proof side panel. d. Repeat steps a to c to obtain another leak-proof partition.
10. A manufacturing process for an air-feeling side-parted diaper according to claim 4, characterized in that, Includes the following steps:
1. Preparation of a liquid-permeable surface layer; II. Preparation of the absorber core layer; III. Preparation of an impermeable liquid bottom layer; IV. Preparation of leak-proof partitions; V. Stack and fix the products from steps one, two, and three together. Simultaneously, symmetrically place the leak-proof partition obtained in step four on the impermeable bottom layer on both sides of the absorbent core. Then, perform arc-shaped edge cutting and slit to form individual absorbent items. Step four includes: a. Take a water-repellent flexible material as the side-separating non-woven fabric (1), fold both sides of the side-separating non-woven fabric (1) once to form a double-layer structure with both edges overlapping, and apply glue to the ends of the folded side-separating non-woven fabric (1) to seal it. b. Apply adhesive to the surface of the double-layered nonwoven fabric with side septum (1) and fix the side septum rubber (2) at the adhesive application position. c. Fold the non-woven fabric (1) with the side folding to form a four-layer structure, and apply adhesive to the ends of the folded non-woven fabric (1) to seal it. d. Cut at the center of symmetry of the nonwoven fabric (1) to obtain two symmetrical leak-proof partitions.
