Description

Technical Field

[0001] This utility model relates to the technical field of absorbent product waistband structure, specifically a hydrophilic sandwich moisture-absorbing diaper bubble waistband structure. Background Technology

[0002] The bubble waistband, with its unique three-dimensional design, not only enhances the overall aesthetics of the diaper but, more importantly, achieves a significant breakthrough in wearing comfort. Its unique bubble structure better conforms to the user's waistline, effectively reducing the feeling of constriction and allowing for greater freedom of movement. Simultaneously, the bubble waistband enhances the seal between the diaper and the waist, reducing the risk of urine leakage and providing more reliable protection for the user.

[0003] Building upon the advantages of bubble waistbands, existing technology has been further developed. Patent CN202221372574.8 proposes a 3D integrated bubble waistband structure. This structure is primarily composed of non-woven fabric. The non-woven fabric is folded and placed along the length of the pants to form an outer covering layer. Then, both ends of the outer covering layer are folded again and looped into a ring, covering the width of the pants with the folded opening side facing outwards, thus forming an inner covering layer. A first adhesive layer is placed between the outer covering layer and the bottom layer, while a second adhesive layer is placed on the surface of the pants outside the first adhesive layer. The outer covering layer portion outside the second adhesive layer and the inner covering layer portion together constitute the integrated waistband. Through the combination of adhesive and elastic threads, the interior of the integrated waistband is divided into several bubble cavities, thus forming an integrated bubble waistband with a unique texture. This design ensures that when the user wears it, the elastic threads contract without directly affecting the skin, greatly reducing the pressure sensation when the elastic threads come into contact with the skin, ensuring both a secure fit and significantly improving wearing comfort.

[0004] However, although the bubble waistband performed well in improving wearing comfort, it also had some shortcomings in actual use. Specifically, because the bubble waistband lacked hydrophilic moisture-absorbing material in the upper area, the upper area of ​​the waistband lacked active moisture absorption capacity. When the baby was in motion or wore it for a long time, sweat and moisture easily accumulated on the surface of the waistband in contact with the skin. This area could not achieve rapid absorption of moisture through the material properties, which further caused local skin dampness and discomfort. Utility Model Content

[0005] To address the technical deficiencies in the background art, this utility model proposes a hydrophilic sandwich moisture-absorbing diaper bubble waistband structure, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:

[0006] A hydrophilic sandwich moisture-absorbing diaper bubble waistband structure includes an absorbent body and a double-layer bubble waistband disposed at both ends of the absorbent body along its length. The double-layer bubble waistband includes an inner nonwoven fabric, an outer nonwoven fabric arranged parallel to the inner side of the inner nonwoven fabric, a plurality of second and third welding points for intermittently bonding the inner and outer nonwoven fabrics, and elastic ribs. The inner and outer nonwoven fabrics are folded parallel to the absorbent body at both ends along its length to form the main structure of the double-layer bubble waistband. The double-layer bubble waistband includes an upper waistband area, a middle waistband area, and a lower waistband area arranged sequentially from top to bottom. A hydrophilic moisture-absorbing layer is sandwiched between the inner and outer nonwoven fabrics in the upper waistband area. The inner and outer nonwoven fabrics are connected by the second and third welding points to form bubble cavities on the inner and outer sides of the middle waistband area of ​​the double-layer bubble waistband.

[0007] As a further technical solution of this utility model, the hydrophilic moisture-absorbing layer is either SSS hydrophilic nonwoven fabric or weldable high-strength wet-strength paper.

[0008] As a further technical solution of this utility model, a number of first welding points for intermittently compositing the outer non-woven fabric and the hydrophilic moisture-absorbing layer are provided in the upper waist area. The first welding points are arranged in a single row along the length of the upper waist area, and the first welding points in adjacent single rows are arranged alternately in a W-shaped direction.

[0009] As a further technical solution of this utility model, the shapes of the first solder point, the second solder point and the third solder point can be selected from any one of ellipse, circle, triangle and square.

[0010] As a further technical solution of this utility model, the second welding point is arranged in a single or double row along the length of the middle waist area, and the third welding point is arranged in a single row at the bottom of the middle waist area, and several rows of third welding points are arranged along the length of the middle waist area.

[0011] As a further technical solution of this utility model, the column spacing of the second welding points arranged in a single column along the length of the mid-waist region is 8.5-15.5 mm, the row spacing between the second welding points in the same column is 1-5 mm, and the area of ​​a single second welding point in the same column is 0.25-1.0 mm². 2 .

[0012] As a further technical solution of this utility model, the column spacing of the second welding points arranged in single or double rows along the length direction of the mid-waist region is 9.0-14.0 mm, the column spacing between the second welding points in a double row is 0.2-2.5 mm, the row spacing between the second welding points in a double row is 2.0-5.0 mm, and the area of ​​a single second welding point in a double row is 0.25-0.75 mm². 2 .

[0013] As a further technical solution of this utility model, the elastic ribs are equidistantly arranged between the two inner layers of nonwoven fabric in the upper waist area and the middle waist area, and between the inner and outer layers of nonwoven fabric in the lower waist area along the length direction of the double-layer bubble waistband.

[0014] The beneficial effects of this utility model are as follows:

[0015] By incorporating a hydrophilic and moisture-absorbing layer with excellent hydrophilicity and hygroscopicity inside the upper waistband, sweat and moisture can be quickly absorbed and locked in, preventing local skin dampness and discomfort. This improves the moisture absorption performance of the diaper's waistband, keeping the baby's waist area dry. The middle waistband area forms a bubble cavity through the second and third welding points, while the upper waistband area uses the first welding point to intermittently composite the hydrophilic and moisture-absorbing layer. The inner and outer layers are bonded together with dot matrix welding points to form an inner and outer bubble structure. This ensures a fluffy and soft feel on the waistband surface, providing a comfortable wearing experience, while also ensuring the structural strength of the waistband. Elastic ribs are reasonably and evenly placed in different areas, further enhancing the elasticity and fit of the waistband, making the diaper more comfortable and practical to wear overall.

Detailed Implementation

[0020] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0021] Combination Figures 1 to 3 As shown, this utility model discloses a hydrophilic sandwich moisture-absorbing diaper bubble waistband structure, including an absorbent body 1 and a double-layer bubble waistband 2 disposed at both ends of the absorbent body 1 along its length. The double-layer bubble waistband 2 includes an inner non-woven fabric 24, an outer non-woven fabric 25 disposed parallel to the inner side of the inner non-woven fabric 24, a plurality of second welding points 221 and a plurality of third welding points 223 for intermittently bonding the inner non-woven fabric 24 and the outer non-woven fabric 25, and elastic ribs 26. The inner non-woven fabric 24 and the outer non-woven fabric 25 are disposed at both ends of the absorbent body 1 along its length. The main structure of the double-layer bubble waistband 2 is formed by folding the end of the absorbent body 1 in parallel to the inside. The double-layer bubble waistband 2 includes an upper waistband area 21, a middle waistband area 22 and a lower waistband area 23 arranged sequentially from top to bottom. A hydrophilic moisture-absorbing layer 212 is sandwiched between the inner non-woven fabric 24 and the outer non-woven fabric 25 in the upper waistband area 21. The inner non-woven fabric 24 and the outer non-woven fabric 25 are connected by the second welding point 221 and the third welding point 223 to form bubble cavities 222 on the inner and outer sides of the middle waistband area 22 of the double-layer bubble waistband 2.

[0022] In the above structure, the absorbent body 1 includes a surface layer 11, an absorbent core 12 and a bottom layer 13 arranged sequentially from the inside to the outside along the thickness direction of the absorbent body 1. The surface layer 11 is composited with the outer nonwoven fabric 25 in the lower waist area 23, and the bottom layer 13 is composited with the inner nonwoven fabric 24 in the lower waist area 23.

[0023] The inner non-woven fabric 24 and the outer non-woven fabric 25 of the double-layer bubble waistband 2 of this utility model are connected by a welding point array formed by the second welding point 221 and the third welding point 223 to form the double-layer bubble waistband 2. The double-layer bubble waistband 2 can maintain the stiffness of the waistband structure while ensuring the fluffy and soft touch of the waistband structure surface, which improves the stability of the diaper product when worn. It makes the diaper fit the baby's body without losing the necessary support due to being too soft, and brings a comfortable wearing experience to the baby.

[0024] This invention features a hydrophilic moisture-absorbing layer 212 with good hydrophilicity and hygroscopicity within the upper waist area 21, positioned between the inner non-woven fabric 24 and the outer non-woven fabric 25. When the infant is active or wears the garment for an extended period, sweat and moisture easily accumulate on the skin-contact surface. The hydrophilic moisture-absorbing layer 212, thanks to its material properties, quickly absorbs and locks in this moisture, preventing localized skin dampness and discomfort, and keeping the infant's waist area dry. Furthermore, the hydrophilic moisture-absorbing layer 212 also... To a certain extent, it increases the overall stiffness of the waistband, making it fit the baby's body better and less prone to deformation. The upper waistband area 21 is intermittently composited with the outer non-woven fabric 25 and the hydrophilic moisture-absorbing layer 212 through the first welding point 211. Combined with the bubble cavity 222 formed by the second welding point 221 and the third welding point 223 in the middle waistband area 22, as well as the reasonable setting of the elastic ribs 26, it ensures the soft and fluffy touch of the waistband surface and brings a comfortable wearing experience, while ensuring the structural strength of the waistband and improving the elasticity and fit of the waistband.

[0025] As one of the preferred embodiments of this utility model, the hydrophilic moisture-absorbing layer 212 is either SSS hydrophilic nonwoven fabric or weldable high-strength wet-strength paper.

[0026] SSS hydrophilic nonwoven fabric has good hydrophilicity and moisture absorption, which can quickly absorb and lock in sweat and moisture that accumulates in the contact area between the waistband and the skin, avoiding local skin dampness and discomfort, and keeping the baby's waistband area dry. At the same time, its material properties also help to increase the overall stiffness of the waistband, making the waistband fit the baby's body better and less prone to deformation.

[0027] Furthermore, when it is necessary to further improve the moisture absorption performance of SSS hydrophilic nonwoven fabric, wood pulp fibers can be added to SSS hydrophilic nonwoven fabric to increase the moisture absorption capacity of SSS hydrophilic nonwoven fabric in the upper waist area 21.

[0028] The weldable high-strength wet-strength paper is a high-strength wet-strength paper with a hydrophilic modified porous polyethylene film layer on its surface. The weldable high-strength wet-strength paper has good hydrophilic moisture absorption properties, which can effectively absorb moisture and reduce the feeling of dampness on the skin. Moreover, its strength characteristics can provide a certain support for the waistband. While ensuring the moisture absorption effect, it enhances the stability of the waistband structure. In conjunction with the inner non-woven fabric 24 and the outer non-woven fabric 25, after being intermittently bonded through the first welding point 211, it can be better integrated into the double-layer bubble waistband 2 structure. Together, they can ensure the fluffy and soft touch of the waistband surface and bring a comfortable wearing experience, while ensuring the structural strength of the waistband and improving the overall comfort and practicality of the diaper.

[0029] As one of the preferred embodiments of this utility model, the shapes of the first solder point 211, the second solder point 221 and the third solder point 223 can be selected from any one of ellipse, circle, star, triangle and square.

[0030] In the structure of the double-layer bubble waistband 2, the shape selection of the first welding point 211, the second welding point 221, and the third welding point 223 will have a certain impact on the fluffy feel of the double-layer bubble waistband 2. Elliptical and circular welding points are rounded, and the bonding area transitions smoothly under the same area. When the area is small and the distribution is reasonable, the bonding range can be controlled to ensure the structural strength, leave space for the bubble cavity 222, reduce the damage to the fluffiness of the double-layer bubble waistband 2, and keep the double-layer bubble waistband 2 with a good fluffy feel. Star-shaped, triangular, and square welding points have more corners. When the area is large, the corners will strongly bind the non-woven fabric of the double-layer bubble waistband 2, affecting the fluffiness. However, when the area is small and the distribution is reasonable, the fluffy feel can be maintained to a certain extent by increasing the gaps between the welding points.

[0031] Combination Figures 1 to 3 As shown, in one of the preferred embodiments of the present invention, the upper waist region 21 is provided with a plurality of first welding points 211 for intermittently compositing the outer nonwoven fabric 25 and the hydrophilic moisture-absorbing layer 212. The first welding points 211 are arranged in a single row along the length of the upper waist region 21, and the first welding points 211 in adjacent single rows are arranged alternately in a W-shape.

[0032] In the above structure, by setting several first welding points 211 to intermittently composite the outer non-woven fabric 25 and the hydrophilic moisture-absorbing layer 212, the outer non-woven fabric 25 and the hydrophilic moisture-absorbing layer 212 in the upper waist area 21 can be firmly connected together to form a stable overall structure. This helps to prevent the outer non-woven fabric 25 and the hydrophilic moisture-absorbing layer 212 from separating or shifting during use, ensuring the integrity and reliability of the double-layer bubble waist 2 structure. The intermittent composite method of setting the first welding points 211 can minimize the impact on the softness of the upper waist area 21 while ensuring the connection strength. The alternating staggered arrangement of adjacent single-row first welding points 211 in a W-shape avoids the problem of local hardness in the upper waist area 21 that may be caused by excessively dense welding points, so that the upper waist area 21 can maintain relative softness, comfort and fluffiness while providing support.

[0033] Combination Figure 2 and Figure 3 As shown, in one of the preferred embodiments of the present invention, the second solder joint 221 is arranged in a single or double row along the length of the middle waist region 22, and the third solder joint 223 is arranged in a single row in the lower part of the middle waist region 22, and several rows of the third solder joint 223 are arranged along the length of the middle waist region 22.

[0034] In the above structure, the second welding point 221 is used to intermittently composite the inner nonwoven fabric 24 and the outer nonwoven fabric 25, and is arranged in a single or double row along the length direction in the mid-waist area 22. This intermittent composite method makes the inner nonwoven fabric 24 and the outer nonwoven fabric 25 form bubble cavities 222 in the areas not connected by welding points. The presence of bubble cavities 222 gives the waist structure a fluffy and soft touch, making it more comfortable for the baby to wear and reducing friction and irritation to the baby's skin.

[0035] The third weld point 223 is set in a single row in the lower part of the middle waist area 22, and several rows are set along the length direction. This local reinforcement method can enhance the structural strength of the lower part of the middle waist area 22 and prevent the part from tearing or deforming due to excessive force during use. Especially when the baby is moving, the lower part of the waist will bear a large amount of tension and friction. The setting of the third weld point 223 can effectively improve the durability of the waist.

[0036] Combination Figure 2 As shown, as a further embodiment of the above solution, when the second solder joints 221 are arranged in a single column along the length of the mid-waist region 22, the column spacing of the second solder joints 221 in the single column along the length of the mid-waist region 22 is 8.5-15.5 mm, the row spacing between the second solder joints 221 in the same column is 1-5 mm, and the area of ​​a single second solder joint 221 in the same column is 0.25-1.0 mm². 2 .

[0037] In the above structure, the second welding point 221 in a single row is set with a column spacing of 8.5-15.5 mm along the length of the waist area 22, and the row spacing between welding points in the same column is 1-5 mm. This can control the size of the unwelded area between the inner non-woven fabric 24 and the outer non-woven fabric 25, thereby forming a bubble cavity 222 of appropriate size and even distribution. The presence of the bubble cavity 222 gives the waist structure a fluffy and soft feel, making it more comfortable for the baby to wear and reducing friction and irritation to the baby's skin.

[0038] The area of ​​a single second solder joint 221 is 0.25-1.0 mm. 2 The appropriate welding point area will not excessively damage the overall structure of the nonwoven fabric. While ensuring the connection strength between the inner nonwoven fabric 24 and the outer nonwoven fabric 25, the fluffiness of the bubble cavity 222 is preserved to the maximum extent. This balance allows the waistband structure to have a soft touch while providing a certain degree of support through the bubble cavity 222, preventing the waistband from becoming too soft and slump.

[0039] Specifically, among the above parameters, the column spacing of the second weld points 221 in a single column along the length of the mid-waist region 22 is preferably 11 mm, the row spacing between the second weld points 221 in the same column is preferably 2.5 mm, and when the shape of the second weld point 221 is preferably elliptical, the area of ​​a single second weld point 221 in the same column is 0.80 mm². 2 .

[0040] Combination Figure 3 As shown, as a further embodiment of the above solution, when the second solder joints 221 are arranged in two rows along the length of the mid-waist region 22, the column spacing of the two rows of second solder joints 221 along the length of the mid-waist region 22 is 9.0-14.0 mm, the column spacing between the second solder joints 221 in the two rows is 0.2-2.5 mm, the row spacing between the second solder joints 221 in the two rows is 2.0-5.0 mm, and the area of ​​a single second solder joint 221 in the two rows is 0.25-0.75 mm². 2 .

[0041] In the above structure, the column spacing of the double-row second welding points 221 along the length of the mid-waist region 22 is set to 9.0-14.0 mm, the column spacing between the welding points in the double rows is 0.2-2.5 mm, and the row spacing is 2.0-5.0 mm. By setting the spacing, the unwelded areas between the inner non-woven fabric 24 and the outer non-woven fabric 25 can be precisely controlled, forming appropriately sized and regularly distributed, stable bubble cavities 222. The presence of the bubble cavities 222 gives the waistband structure a fluffy and soft feel, making it more comfortable for babies to wear.

[0042] The area of ​​a single second solder joint 221 is 0.25-0.75 mm. 2 The relatively small welding point area does not excessively damage the overall structure of the nonwoven fabric. While ensuring the connection strength between the inner nonwoven fabric 24 and the outer nonwoven fabric 25, it maximizes the preservation of the fluffiness of the bubble cavity 222. This balance allows the waistband structure to have a soft touch while providing a certain degree of support through the bubble cavity 222, preventing the waistband from becoming too soft and slump.

[0043] Compared to a single row, the double-row second welding point 221 significantly enhances the structural strength of the mid-waist area 22. The double-row welding points are reasonably distributed along the length direction, making the welding point distribution more dense and uniform. This effectively prevents excessive deformation or displacement of the waistband during the baby's activities, thereby maintaining the stability of the waistband structure and ensuring that the diaper always fits the baby's body tightly.

[0044] Specifically, among the above parameters, when the second solder points 221 are arranged in two rows along the length of the mid-waist region 22, the column spacing of the two rows of second solder points 221 along the length of the mid-waist region 22 is preferably 11.7 mm, the column spacing between the second solder points 221 within the two rows is 1.8 mm, the row spacing between the second solder points 221 within the two rows is 3.33 mm, and when the shape of the second solder point 221 is preferably circular, the area of ​​a single second solder point 221 within the two rows is 0.5 mm². 2 .

[0045] Combination Figure 1 As shown, in one of the preferred embodiments of this utility model, the elastic ribs 26 are equidistantly arranged along the length direction of the double-layer bubble waistband 2 between the two inner layers of nonwoven fabric 24 in the upper waistband region 21 and the middle waistband region 22, and between the inner layer of nonwoven fabric 24 and the outer layer of nonwoven fabric 25 in the lower waistband region 23.

[0046] In the mid-waist region 22, the inner non-woven fabric 24 and the outer non-woven fabric 25 are connected by the second welding point 221 and the third welding point 223 to form a bubble cavity 222. The elastic ribs 26 provide support for the bubble cavity 222, preventing it from deforming or collapsing excessively when subjected to external pressure. It acts like an invisible frame, maintaining the shape and structure of the bubble cavity 222, thus ensuring the fluffy and soft feel of the waist structure surface.

[0047] The upper waist area 21 contains a hydrophilic moisture-absorbing layer 212, and the elastic ribs 26 further enhance the overall rigidity of the double-layer bubble waistband 2 by setting up the entire waist area. The elastic ribs 26 can work together with the hydrophilic moisture-absorbing layer 212 and the bubble cavity 222 to ensure that the waistband has sufficient strength and stability while maintaining a soft touch, avoiding the situation of collapsing, and ensuring that the diaper can always fit the baby's body during wear, providing a good wearing experience.

[0048] The elastic band 26 allows the double-layer bubble waistband 2 to tightly wrap around the baby's waist, reducing waistband shifting during wear. When the baby moves, the elastic band 26 automatically adjusts the tightness of the waistband, maintaining a close fit and preventing urine or feces leakage due to waistband shifting. The close-fitting waistband structure better blocks urine and feces leakage.

[0049] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
