Description

Technical Field

[0001] This utility model relates to the field of hygiene products technology, and in particular to a high absorbency core and hygiene products. Background Technology

[0002] Currently, Chinese Patent Publication No. CN208770166U discloses a dry baby diaper, including a diaper body. The diaper body is defined to have a longitudinal direction along its length and a transverse direction along its width. The diaper body includes a liquid-permeable surface layer, a liquid-impermeable bottom layer, and an absorbent core disposed between the two. The liquid-impermeable bottom layer is composed of a breathable film and a bottom non-woven fabric disposed on its bottom surface. A moisture-absorbing material layer is disposed between the absorbent core and the breathable bottom film, and the moisture-absorbing material layer is disposed where the projections of the absorbent core and the breathable bottom film in the longitudinal direction do not overlap. This discloses a conventional diaper structure. The existing absorbent core is usually made of a mixture of fluff pulp fiber and superabsorbent polymer. For comfort, it is usually pressed into an ultra-thin sheet shape by a pressure roller. However, this absorbent core has low conformity to the human body during female use. Utility Model Content

[0003] Therefore, in view of the above problems, this utility model proposes a highly absorbent core and sanitary products, which solves the technical problem of low fit between the existing absorbent core and the human body during female use.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a high absorbency core and sanitary product, comprising a base film, a first absorbent body disposed on the left and right sides of the base film surface, a second absorbent body containing viscose fiber, and a surface non-woven fabric disposed on the surfaces of the first absorbent body and the second absorbent body, wherein the second absorbent body is disposed in the middle of the base film surface, and a foamed cotton strip is disposed on the bottom surface of the second absorbent body.

[0005] Furthermore, a recessed portion is provided at the top between the second absorber and the first absorber, and hydrophilic yarns are provided on the recessed portion.

[0006] Furthermore, the thickness of the foamed cotton strip is 1mm to 2mm.

[0007] Furthermore, the cross-sectional shape of the foamed cotton strips is convex.

[0008] Furthermore, the first absorber has a spunbond nonwoven fabric in its middle part.

[0009] A highly absorbent sanitary product includes a highly absorbent core as described above, and further includes an outer nonwoven fabric, a front elastic band composited at the front end of the outer nonwoven fabric, a rear elastic band composited at the rear end of the outer nonwoven fabric, elastic guards disposed on both sides of the absorbent core, and a welded portion for composited on the outer nonwoven fabric at the positions of the front and rear elastic bands, wherein the highly absorbent core is disposed in the middle of the outer nonwoven fabric.

[0010] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0011] This highly absorbent core features a foam strip positioned at the bottom of a second absorbent body in the center. The second absorbent body is separate and taller than the first, creating an upward bulge in the center for efficient liquid absorption. Due to the shrinkage resistance of the foam strip, it expands under the pressure of the production line, maintaining the upward bulge of the second absorbent body. Even after being folded and compressed in a sealed individual package, opening the package allows the foam strip to expand and lift the second absorbent body upwards, ensuring a comfortable fit for women. This solves the technical problem of low body fit in existing absorbent cores. Attached Figure Description

[0014] Figure 3 This is a schematic diagram of the structure of the high-absorption hygiene product of this utility model. Detailed Implementation

[0015] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0016] refer to Figures 1 to 3 This embodiment provides a high-absorbency core, including a bottom film 1, a first absorbent 2 disposed on the left and right sides of the surface of the bottom film 1, a second absorbent 3 containing viscose fiber, and a surface non-woven fabric 4 disposed on the surface of the first absorbent 2 and the second absorbent 3. The second absorbent 3 is disposed in the middle of the surface of the bottom film 1, and a foamed cotton strip 5 is disposed on the bottom surface of the second absorbent 3.

[0017] The foamed cotton strip 5 is set on the bottom surface of the second absorbent body 3 in the middle position. The second absorbent body 3 is set separately and its height will be higher than that of the first absorbent body 2. The middle part of the absorbent core will be raised upward, which can absorb liquid in time. Because the foamed cotton strip 5 has anti-shrinkage properties, when the absorbent core is rolled by the production line, the foamed cotton strip 5 has expansion properties, which can keep the second absorbent body 3 in an upward raised state. Even after being folded and compressed in a sealed individual package, after opening the individual package, the foamed cotton strip 5 will expand and push the second absorbent body 3 upward, so that the middle part of the absorbent core fits the woman's use.

[0018] The foamed cotton strips are made of soft material and have a small volume when compressed, which is conducive to the packaging of thin absorbent cores. At the same time, when the human body is in a sitting position, they are soft and flattened when compressed, resulting in low discomfort and good performance.

[0019] The first absorbent 2 is a mixture of fluff pulp fiber and superabsorbent polymer. The first absorbent 2 has a spunbond nonwoven fabric 8 in the middle for layering fluff pulp fiber and superabsorbent polymer. The manufacturing process and mixing ratio of fluff pulp fiber and superabsorbent polymer are conventional technologies in the field and will not be described in detail here.

[0020] The fluff pulp fibers and super absorbent polymers have high absorption capacity. When liquid seeps downward through the first absorbent body 2, it is absorbed by the fluff pulp fibers and super absorbent polymers at the bottom through the spunbond nonwoven fabric. Because the middle part is layered through the spunbond nonwoven fabric, which has unidirectional water-wicking properties, the liquid that is saturated at the bottom of the first absorbent body 2 is not easily back-seeped to the top of the first absorbent body 2 due to the water-repellent properties of the spunbond nonwoven fabric, thus improving the user experience.

[0021] The second absorbent 3 includes a wrapping layer and a fiber absorbent layer disposed within the wrapping layer. The fiber absorbent layer is made of a mixture of viscose fiber, cotton fiber and wool pulp fiber. The wrapping layer is made of spunlace nonwoven fabric, and the fiber absorbent layer is made of water-absorbing fiber. The mixing process and ratio of viscose fiber, cotton fiber and wool pulp fiber are conventional technologies in the field and will not be described in detail here. Spunbond nonwoven fabric and spunlace nonwoven fabric are commercially available materials, and the materials are conventional technologies in the field and will not be described in detail here.

[0022] A recessed portion 6 is provided at the top between the second absorber 3 and the first absorber 2. A hydrophilic yarn 7 is provided on the recessed portion 6. The hydrophilic yarn 7 is preferably spandex yarn or cotton yarn, which has good liquid conductivity during use.

[0023] The hydrophilic yarn 7 has a strong guiding effect. After contacting the liquid, it quickly guides the liquid forward and backward, allowing the liquid to penetrate downward and be absorbed by the first absorber 2 and the second absorber 3.

[0024] The thickness of the foamed cotton strip 5 is 1mm to 2mm, and the cross-sectional arrangement of the foamed cotton strip 5 is "convex". With this shape, the top center of the second absorbent body 3 is not easily flattened in the packaging state. The surface non-woven fabric 4 is a hydrophilic non-woven fabric. The foamed cotton strip 5 is preferably polyethylene foamed cotton, and the thickness is preferably 1mm to 2mm. This is a conventional technology and will not be described in detail here. This thickness provides good softness, and the thickness increases only slightly after the absorbent core is folded and packaged, making it convenient to pack into boxes.

[0025] A highly absorbent sanitary product includes a highly absorbent core as described above, an outer nonwoven fabric 100, a front elastic band 110 compositely disposed at the front end of the outer nonwoven fabric 100, a rear elastic band 120 compositely disposed at the rear end of the outer nonwoven fabric 100, elastic guards 200 disposed on both sides of the absorbent core, and a welding part 130 for compositely disassembling the outer nonwoven fabric 100 on both sides of the positions of the front elastic band 110 and the rear elastic band 120. The highly absorbent core is disposed in the middle of the outer nonwoven fabric 100. This sanitary product fits the female genitalia better during wear and use, resulting in better absorption.
