Description

Technical Field

[0001] This utility model relates to the field of hygiene products, specifically to a hygiene product fabric, core, and hygiene product. Background Technology

[0002] Hygiene products include sanitary napkins, diapers, pull-ups, etc., and are mainly used by infants and women. Currently, hygiene products mainly consist of a top layer, a distribution layer, a core, and a bottom layer. During use, the top layer comes into contact with the skin. Fluids such as urine and loose stools from infants, and menstrual blood from women, are absorbed by the top layer. The fluids then flow down through the distribution layer to the core, where they are absorbed and stored. The bottom layer is an outer membrane that prevents leakage of fluids from the product.

[0003] Infant urine is primarily located in the middle or front of the crotch area of ​​sanitary products, while loose feces are located in the back. After excretion, urine easily seeps through the surface layer and drainage layer into the core and is absorbed. However, loose feces contain both liquid and solid matter. While the liquid in feces can quickly seep through the surface layer and drainage layer into the core and be absorbed, the solid matter cannot be absorbed quickly or at all. This results in a large amount of fecal matter adhering to the infant's buttocks, requiring extensive wiping and washing. During this process, the presence of so much fecal matter can cause annoyance, nausea, and vomiting for the person washing the buttocks, leading to discomfort. Furthermore, the prolonged adhesion of fecal matter to the infant's buttocks can also cause discomfort.

[0004] For women, menstrual blood usually contains some solids. These solids are mainly a mixture of shed uterine lining tissue, cells or tissue fragments, blood clots and other bodily fluids. After the blood is absorbed into the sanitary product, the remaining solids will not enter the sanitary product. The solids will stick to the woman's buttocks, causing discomfort. Utility Model Content

[0005] This utility model aims to provide a sanitary product fabric, core, and sanitary product, which divides the fabric, core, and crotch area of ​​the sanitary product into sections. By improving the back area of ​​the fabric, it can accommodate part of the human body's excrement, reducing the amount of excrement adhering to the buttocks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sanitary product fabric, the surface of which is flat or patterned; the fabric surface is divided into a front area, a middle area and a back area, the middle area being located between the front area and the back area; the back area is provided with a receiving space for accommodating excrement.

[0007] The principle and advantages of this solution are as follows: The fabric surface in this application is divided into a front zone, a middle zone, and a back zone. The fabric is applied to sanitary products. The middle zone is located in the middle of the crotch area of ​​the sanitary product, the front zone is located in the front part of the crotch area, and the back zone is located in the back part of the crotch area. The back zone is opposite to the buttocks, and excretory solids (such as fecal matter or solids and adhesives from menstrual blood) are located in the back zone. The liquid from the excretory waste is absorbed by the core through the surface of the sanitary product. Because the back zone has a space for accommodating excretory solids, some of the excretory solids will enter the space, thus reducing the amount of excretory solids adhering to the buttocks. This not only improves the comfort of the buttocks but also reduces the workload of cleaning feces adhering to the baby's buttocks when the baby uses the product. With less feces adhering to the buttocks, it also helps to alleviate and reduce the annoyance, nausea, and vomiting experienced by the person washing the baby.

[0008] Preferably, as an improvement, the rear area is provided with multiple protrusions, and there are gaps between adjacent protrusions, the gaps being accommodating spaces.

[0009] As a result, the excreted solids enter the gap between adjacent protrusions. The excreted solids are contained in the gap, and the protrusions act on the skin of the buttocks to support the excreted solids in the gap. The excreted solids in the gap are less likely to adhere to the skin, reducing the dispersion of excreted solids on the buttocks, thereby reducing the amount of excreted solids adhering to the buttocks.

[0010] Preferably, as an improvement, the protrusion is in the shape of a circular block, a polygonal block, a strip, or an irregularly shaped block. Therefore, since the shape of the protrusion and the accommodating space have little impact on the capacity for excreted solids, different shapes can be chosen for the protrusion.

[0011] Preferably, as an improvement, the rear area is provided with multiple seepage holes, which serve as containment spaces.

[0012] The containment space is designed in the form of a perforation hole. Excreted solids enter the perforation hole and are contained there. After the excreted solids enter the perforation hole, the amount of excreted solids between the sanitary product surface and the buttocks is reduced, thus reducing the dispersion of excreted solids on the buttocks and reducing the amount of feces adhering to the buttocks.

[0013] Preferably, as an improvement, the front area has multiple protrusions with gaps between adjacent protrusions.

[0014] Therefore, when sanitary products are worn, the protruding part of the front area of ​​the crotch area acts on the skin, and the protruding part has a supporting function. The design of the protruding part creates a gap between the front part of the crotch area of ​​the sanitary product and the skin. The gap between adjacent protruding parts can serve as a ventilation channel. In this way, the front part of the crotch area of ​​the sanitary product will not be completely pressed against the skin, which helps to improve the breathability of the sanitary product and makes it more comfortable to wear.

[0015] Preferably, as an improvement, the protrusion is in the shape of a circular block, a polygonal block, a strip, or an irregularly shaped block. Therefore, since the shape of the protrusion has little effect on improving breathability or reducing the amount of the entire front surface of the sanitary product's crotch area adhering to the skin, the shape of the protrusion can be set to different shapes.

[0016] Preferably, as an improvement, the volume of the protrusions gradually decreases from the rear end away from the center area towards the center; the volume of the protrusions gradually decreases from the front end away from the center area towards the center. Thus, the volume of the protrusions gradually increases from the center area towards the rear end away from the center, and the volume of the protrusions gradually increases from the center area towards the front end away from the center. This gradual transition in the size of both the protrusions and protrusions towards the center improves aesthetics. Furthermore, the skin in the center of the crotch is more sensitive than the skin in the front and back areas. This design ensures that the volume of the protrusions and protrusions is smaller closer to the center, resulting in a smoother fabric surface and improved wearing comfort. Conversely, the volume of the protrusions and protrusions increases further away from the center, and the skin in the front and back areas requires less comfort than the skin in the center area. This design also increases the rear area's capacity to hold excreted waste and ensures breathability in the front area.

[0017] To achieve the above objectives, the present invention also adopts the following technical solution: a core body, wherein the core body is provided with receiving holes, and the receiving holes are correspondingly provided with seepage holes in the fabric of sanitary products.

[0018] As a result, excreted solids permeate downwards through the seepage holes and can then enter the core's receiving holes, thus further improving the sanitary product's capacity to hold excreted solids and reducing the amount of excreted solids adhering to the buttocks.

[0019] To achieve the above objectives, this utility model also adopts the following technical solution: a sanitary product comprising a surface layer, a diversion layer, a core, and a bottom film laminated together, wherein the sanitary product fabric serves as the surface layer. Thus, by using the fabric described in this application on the sanitary product, the sanitary product can better contain excreted solids, reducing the amount of excreted solids adhering to the buttocks.

[0020] To achieve the above objectives, this utility model also adopts the following technical solution: a sanitary product comprising a composite surface layer, a flow-guiding layer, a core, and a bottom film, with the sanitary product fabric serving as the surface layer; the flow-guiding layer has connecting holes, and the connecting holes, seepage holes, and receiving holes are connected to form a cone shape. Therefore, by using the fabric described in this application on the sanitary product, the sanitary product can better accommodate excreted solids, reducing the amount of excreted solids adhering to the buttocks. In this solution, excreted solids flow into the connecting holes in the flow-guiding layer through the seepage holes, and then continue to permeate downwards through the connecting holes, thereby entering the receiving holes of the core, improving the sanitary product's capacity to accommodate excreted solids and reducing the amount of excreted solids adhering to the buttocks. The connecting holes, seepage holes, and receiving holes are connected to form a cone shape, resulting in a larger cone-shaped opening on the surface layer, making it easier for excreted solids to enter and be accommodated in the sanitary product.

[0025] The following detailed description illustrates the specific implementation method:

[0027] Example 1

[0028] The basics are as follows: Figure 1 , Figure 4 As shown: This embodiment discloses hygiene products. Hygiene product 1 is a product used by infants or women, such as diapers, pull-up pants, and sanitary napkins. This embodiment uses diapers used by infants as an example for description and explanation.

[0029] In this embodiment, the sanitary product 1 includes a surface layer 9, a flow-guiding layer 10, a core 11, and a bottom film 12. The surface layer 9, the flow-guiding layer 10, the core 11, and the bottom film 12 are sequentially laminated together. The sanitary product 1 is worn on the body, and the surface layer 9 is the layer that comes into contact with the baby's skin.

[0030] In this embodiment, the surface layer 9 is a non-woven fabric 5. The surface of the fabric 5 is either flat (flat means that there are no additional patterns except for the texture of the non-woven fabric itself) or has patterns, such as embossing on the fabric 5 in the prior art, such as square embossing.

[0031] The improvement of fabric 5 in this embodiment is that the surface of fabric 5 is divided into front area 2, middle area 3, and back area 4. For ease of explanation, front area 2, middle area 3, and back area 4 are selected with dashed lines in the figure, but there will be no dashed lines in the actual product. Middle area 3 is located between front area 2 and back area 4. When this fabric 5 is used on the crotch area of ​​sanitary product 1, middle area 3 corresponds to the middle of the crotch, front area 2 corresponds to the front of the crotch, and back area 4 corresponds to the back of the crotch. Front area 2, middle area 3, and back area 4 are the approximate divisions of the crotch area. In actual production, the proportions, widths, and lengths of front area 2, middle area 3, and back area 4 are adjusted accordingly. In this embodiment, middle area 3 is the existing fabric structure. Middle area 3 is provided with some conventional patterns 7 found on existing fabrics, or middle area 3 is flat without patterns 7. More simply, the surface of middle area 3 is the same as the surface layer in the prior art. In this embodiment, the rear area 4 is provided with a space for accommodating excreted solids (infants, this mainly consists of feces; for women, it mainly consists of solid insoluble substances and adhesives from menstrual blood). The accommodating space is specifically implemented as follows: the rear area 4 has multiple seepage holes 8, which serve as the accommodating space. In this embodiment, the seepage holes 8 gradually decrease in size from the end of the rear area 4 towards the middle area 3; that is, the seepage holes 8 closer to the middle area 3 have smaller volumes, while those farther from the middle area 3 have larger volumes. In this embodiment, the seepage holes 8 are circular with a diameter of 1-5 mm. Of course, in other embodiments, the seepage holes 8 can also be other shapes, such as square holes, triangular holes, pentagonal holes, hexagonal holes, etc. In this embodiment, the seepage holes 8 on the fabric 5 can be processed by needle punching, where a needle passes through the non-woven fabric to create the seepage holes 8.

[0032] In this embodiment, the front region 2 has multiple protrusions, which are protrusions 6. There is a gap between adjacent protrusions, with a depth of 1-5 mm. In this embodiment, the protrusions are circular blocks, extending above the surface of the nonwoven fabric. The volume of the protrusions gradually decreases from the end of the front region 2 away from the middle region 3 towards the middle region 3; that is, the closer to the middle region 3, the smaller the volume of the protrusion, and the farther away from the middle region 3, the larger the volume of the protrusion. In this embodiment, the diameter of the protrusion is 1-5 mm. Of course, in other embodiments, the protrusions can also be polygonal blocks, columnar, strip-shaped, or irregularly shaped blocks. In this embodiment, the protrusions can be prepared using existing methods: the nonwoven fabric passes through a pressure roller on the production line. The pressure roller is located on the back of the nonwoven fabric, and the protruding teeth on the pressure roller press the protrusions out from the usable surface of the nonwoven fabric. The shape of the protruding teeth on the surface of the pressure roller is the same as the shape of the processed protrusion.

[0033] Combination Figure 4 As shown, in this embodiment of the sanitary product 1, the drainage layer 10 in the crotch area is provided with a connecting hole 13, and the core 11 is provided with a receiving hole 14. The connecting hole 13 connects the seepage hole 8 and the receiving hole 14, and the connecting hole 13, the seepage hole 8, and the receiving hole 14 are connected to form a cone shape. The connecting hole 13, the seepage hole 8, and the receiving hole 14 can preferably be set in the following way: after the surface layer 9, the drainage layer 10, and the core 11 are combined, the seepage hole 8, the connecting hole 13, and the receiving hole 14 are pierced by a conical needle in the rear area 4 of the surface layer 9, and in the drainage layer 10 and the core 11 corresponding to the rear area 4 of the surface layer 9. Alternatively, the following method can be used: the surface layer 9, the flow guiding layer 10, and the core 11 are needle-punched with infiltration holes 8, connecting holes 13, and receiving holes 14, respectively, and then the surface layer 9, the flow guiding layer 10, and the core 11 are composited. However, in the latter processing method, care must be taken to ensure that the infiltration holes 8, connecting holes 13, and receiving holes 14 are in relative positions before composited.

[0034] In this embodiment, when using the sanitary product 1, the diaper is worn with the back area 4 facing the buttocks. The baby's excrement is concentrated in the back area 4. The liquid in the loose stool seeps through the surface of the sanitary product 1 and the guide layer 10 into the core 11, where it is absorbed. Simultaneously, for the solid fecal matter that is difficult to seep, a portion of the solid matter enters the seepage hole 8 and then through the seepage hole 8 and the connecting hole 13 into the receiving hole 14. This way, the feces are contained within the seepage hole 8, the connecting hole 13, and the receiving hole 14, reducing the amount of feces adhering to the baby's buttocks. This not only improves the baby's comfort but also reduces the workload of cleaning the baby's buttocks. Less feces adhering to the buttocks also helps alleviate or reduce feelings of annoyance, nausea, and vomiting experienced by the cleaning personnel.

[0035] As for the front area 2, which is located on the front side of the baby's body, the front area 2 has a protrusion that acts on the skin. The protrusion prevents the front area 2 from completely adhering to the skin, allowing air to flow in the gaps between the protrusions. This improves the breathability of the sanitary product 1 and enhances the comfort of wearing the sanitary product 1.

[0036] Of course, in other embodiments, only the infiltration holes 8 can be provided in the rear area 4 of the surface layer 9, while the guiding layer 10 and the core 11 do not have the connecting holes 13 and the receiving holes 14. Feces can still be contained through the infiltration holes 8, but the containing effect is not as good as when the guiding layer 10 and the core 11 have the connecting holes 13 and the receiving holes 14. In this case, the rear area 4 needs to be thickened to ensure that the infiltration holes 8 have a certain depth (e.g., 2-5 mm) so as to contain as much feces as possible.

[0037] In addition, the pattern 7 in the figure is only shown in the middle area 3. Of course, in actual implementation, the pattern 7 can also be set in the front area 2 and the rear area 4. The pattern 7 itself is relatively shallow and has no effect on the setting of the protrusion and the seepage hole 8.

[0038] Example 2

[0039] Combination Figure 2 and Figure 3 As shown, this embodiment differs from Embodiment 1 in its arrangement of the rear area 4 for accommodating feces. Instead of using the infiltration holes 8, this embodiment features multiple protrusions, each a protrusion 6, with gaps (1-5mm deep) between adjacent protrusions, serving as accommodating space. The protrusions in this embodiment are circular blocks with a diameter of 1-5mm. However, in other embodiments, the protrusions can be polygonal, cylindrical, strip-shaped, or irregularly shaped. The size of the protrusions in this embodiment is similar to the gradual change in the infiltration holes 8 in Embodiment 1; that is, the closer to the middle area 3, the smaller the volume of the protrusion, and the closer to the end of the rear area 4, the larger the volume. The protrusions in this embodiment are processed in the same way as those in Embodiment 1, using a rolling process.

[0040] The crotch structure of the sanitary product 1 in this embodiment is composed of a surface layer 9 with protrusions, a conventional flow-guiding layer 10, a conventional core 11, and a conventional bottom film 12. Therefore, the difference between the crotch structure of the sanitary product 1 in this embodiment and the prior art is that the structure of the surface layer 9 is different, while the flow-guiding layer 10, core 11, and bottom film 12 are the same as those in the prior art.

[0041] As a result, the excreted feces enter the gap between the adjacent protrusions. The feces are contained in the gap, and the protrusions act on the skin of the buttocks to support the feces in the gap. The feces in the gap are less likely to stick to the skin, thereby reducing the amount of feces adhering to the baby's buttocks.

[0042] Example 3

[0043] The protrusion in Example 2 and the seepage hole 8 in Example 1 can also be set in the rear area 4 at the same time.
