[0029] The following is combined with Figures 1 - 7 The implementation methods of the present invention are described with relevant embodiments, but the implementation methods of the present invention are not limited to the following embodiments, and the present invention involves relevant necessary components in this technical field, which should be regarded as the known technology in this technical field and can be known and mastered by the technicians in this technical field.

[0030] In the hygiene field, an absorbent refers to materials or structures used to absorb and store liquids to keep the user dry and comfortable. In these hygiene products, the absorbent is usually composed of a polymer absorbent layer 3 and other fiber materials. The polymer absorbent layer 3 can quickly absorb and store a large amount of liquid. The fiber materials play a role in supporting and dispersing the liquid, making the absorbent softer, more comfortable, and easier to use.

[0031] The present utility model provides a bundled absorbent, as Figure 1 shown in Figure 2 the figure, which includes a surface layer 1 in direct contact with the human body, a polymer absorbent layer 3 disposed below the surface layer 1, and a bundled fiber aggregate 2 disposed below the polymer absorbent layer 3. An impermeable bottom layer 4 is provided below the bundled fiber aggregate 2, and the bottom layer is disposed on the side of the bundled fiber aggregate away from the polymer absorbent layer 3. In the present utility model, the bundled fiber aggregate 2 provides a stable framework structure for the polymer absorbent layer 3, fixes the polymer absorbent layer 3, so that it is firmly fixed in place, preventing the polymer absorbent layer 3 from overflowing or leaking to the outside. At the same time, the bundled fiber aggregate 2 quickly transfers the liquid on the surface layer 1 to the polymer absorbent layer 3, accelerating the liquid absorption process.

[0032] The manufacturing process of this application: 1) Manufacture the bundled fiber aggregate 2; 2) Unroll the bottom layer 4 and laminate it with the bundled fiber aggregate 2; 3) Lay the polymer absorbent layer 3 on the bundled fiber aggregate 2; 4) Laminate the surface layer 1 above the polymer absorbent layer 3.

[0033] As Figure 3 shown in the figure, the bundled fiber aggregate 2 is formed by longitudinally arranging and aggregating multiple fiber bundles 21, and the bottom ends of the multiple fiber bundles 21 are respectively laminated and connected with the bottom layer 4. The fiber bundle 21 is a bundle-like structure formed by intertwining multiple fiber filaments of one or more different materials. Multiple pores for providing a penetration path for moisture are formed by intertwining between the multiple fiber filaments, and multiple voids formed by the composite of fiber filaments are provided between adjacent fiber bundles 21.

[0034] Here, the formation of multiple pores for providing a penetration path for moisture by intertwining between multiple fiber filaments is different from the multiple voids formed by the composite of fiber filaments provided between adjacent fiber bundles 21. The size and quantity of the pores are determined by the quantity and winding mode of the fiber filaments, while the voids are left after two fiber bundles 21 are bonded with glue.

[0035] The bundled fiber aggregate 2 of the utility model is formed by a plurality of fiber bundles 21 arranged longitudinally, and the longitudinal arrangement and collection can improve the density and overall strength of the fiber. The fiber bundle 21 of the utility model is a bundle structure formed by a plurality of fiber monofilaments of one or more different materials being intertwined and interwoven with each other. By interweaving and winding, there are more gaps between the fiber monofilaments, so that the fiber bundle 21 has a certain plasticity and can adapt to different shapes and curvatures. The gaps between the fiber monofilaments can improve the absorption rate of the bundled fiber aggregate 2, so that the liquid can be quickly transferred from the surface layer 1 to the polymer absorption layer 3, thereby improving the absorption performance of the absorbent.

[0036] like Figure 7 As shown, the polymer absorption layer 3 of the present application includes polymer water-absorbing particles for absorbing and locking liquids. The polymer absorption layer 3 is divided into a plurality of absorption areas 31 , and adjacent absorption areas 31 are spaced a certain distance apart. Figure 7 The multiple absorption areas are distributed in a grid or strip shape, and the liquid can quickly seep down from the polymer space area. The polymer absorption layer 3 can isolate the reverse osmosis of the liquid, and the dryness performance is further guaranteed.

[0037] Embodiment 1

[0038] A cluster absorber, such as Figure 1 and Figure 2 As shown, it includes a surface layer 1 that is in direct contact with the human body, a polymer absorption layer 3 arranged below the surface layer 1, and a bundled fiber aggregate 2 arranged below the polymer absorption layer 3. A liquid-impermeable bottom layer 4 is provided below the bundled fiber aggregate 2. The bottom layer 4 is arranged on the side of the bundled fiber aggregate away from the polymer absorption layer 3. The polymer absorption layer 3 includes polymer water-absorbing particles for absorbing and locking liquid. The bottom layer 4 is arranged on the side of the bundled fiber aggregate 2 away from the polymer absorption layer 3.

[0039] SAP is a typical functional polymer material that can absorb hundreds or even thousands of times its own weight in water and has a strong water retention capacity, so it is also called a super absorbent or high water retention agent. When fixing SAP, factors such as SAP particle size, shape, liquid absorption capacity and distribution uniformity also need to be considered. Reasonable SAP fixing methods can improve the liquid absorption speed, liquid absorption volume and dryness of absorbent products, while reducing leakage and maintaining the overall performance of the product.

[0040] Among them, the absorbent article has the following methods for fixing SAP: the adhesive method, the fiber coating method, the hot melt layer method, and the structural design method. In view of the fact that the adhesive in the adhesive method has certain requirements for the material, and its bonding effect is related to the external environment, there are many usage restrictions; the hot melt layer method needs to be carried out at a higher temperature and also has high requirements for the material of the workpiece itself; the structural design method requires the design of a relatively complex structure, increasing the manufacturing cost and difficulty. In this embodiment, the way of laying oriented polymers is adopted to make the bundled fiber aggregate 2 and the superabsorbent polymer particles composite.

[0041] As Figure 3 shown, the bundled fiber aggregate 2 is formed by longitudinally arranging and aggregating multiple fiber bundles 21. The bundled fiber aggregate 2 is formed by longitudinally aggregating a single layer of fiber bundles 21, which can ensure the density and overall strength of the fibers, and the longitudinal fiber bundles 21 can longitudinally disperse the liquid permeating from the surface layer 1, avoiding excessive accumulation of the liquid in a certain area, thereby improving the overall absorption efficiency and dryness.

[0042] Both ends of the surface layer 1 extend downward along its width direction to wrap the ends of the superabsorbent layer 3, the bundled fiber aggregate 2 and the bottom layer 4 and are pressed on the lower surface of the bottom layer 4, making the overall stability of the absorbent better.

[0043] The superabsorbent polymer is arranged above the bundled fiber aggregate 2, and the liquid seeps down from the interval area of the superabsorbent polymer through the surface layer 1, and is absorbed and stored by the bundled fiber aggregate 2. The superabsorbent polymer in contact with the skin and the non-woven fabric have high dryness, thereby improving the user experience.

[0044] The aspect ratio of the bundled fiber aggregate 2 is 3 to 20. The aspect ratio of the absorbent has a significant impact on its performance and user comfort, that is, the absorption efficiency, and the aspect ratio of the absorbent changes with the aspect ratio of the bundled fiber aggregate 2.

[0045] The following are the impacts of the aspect ratio on the absorbent:

[0046] 1. An appropriate aspect ratio can help the liquid distribute more evenly in the absorbent article. If the aspect ratio is too large or too small, it may cause excessive accumulation of the liquid in a certain area, thereby affecting the absorption efficiency. 2. A larger aspect ratio may allow more space for the liquid to be accommodated in the longitudinal direction of the absorbent article, but insufficient width may limit the lateral diffusion of the liquid. 3. An appropriate aspect ratio can provide a better fitting effect and reduce the irritation caused by friction or discomfort. If the aspect ratio is too large, it may cause unnecessary gaps of the article on the body, reducing the fitting degree and comfort.

[0047] In this embodiment, the aspect ratio of the bundled fiber aggregate 2 is 3 to 20. An aspect ratio within this range can help the liquid distribute more evenly in the absorbent article, enabling the absorbent body to have more space in the longitudinal direction to accommodate the liquid, and the diffusion in the transverse direction is not restricted. At the same time, it fits the user, retains breathability, and improves comfort.

[0048] The fiber bundle 21 is a bundle-like structure formed by multiple fiber filaments of one or more different materials intertwined with each other. The materials of the fiber filaments include at least one of long-staple cotton fiber, viscose fiber, and lyocell fiber. The long-staple cotton fiber has a relatively long fiber length, is thin and soft, milky white or light yellow in color, and is rich in silk luster, with excellent quality. The characteristics of the long-staple cotton fiber make the surface of the textile smoother, the fabric denser, and less likely to pill, so the textiles made of long-staple cotton are more beautiful and durable.

[0049] Lyocell fiber is a material synthesized from natural fiber and man-made fiber. It uses pulp made from renewable bamboo, wood, etc. after being mashed as raw material. There is no chemical reaction in the production process, and the solvent used is non-toxic, so it is a green fiber. Lyocell fiber combines various excellent properties of natural fiber and synthetic fiber, such as softness, comfort, breathability, and easy dyeing. Using at least one of long-staple cotton fiber and lyocell fiber intertwined to form the fiber bundle 21 can improve the water permeability, softness, and comfort of the fiber bundle 21.

[0050] The intertwining makes there be many gaps between the fiber filaments, making the fiber bundle 21 have a certain plasticity. This plasticity enables the fiber bundle 21 to flexibly adapt to various complex shapes and curvatures without being easily broken or damaged. The gaps in the fiber bundle 21 can effectively promote air circulation and reduce moisture retention, thus keeping the inside of the product dry and comfortable. The plasticity of the fiber bundle 21 also helps to improve the comfort and fit of the product. The gaps between the fiber filaments can increase the absorption magnification of the bundled fiber aggregate 2, enabling the liquid to quickly transfer from the surface layer 1 to the high-molecular absorbent layer 3, thereby improving the absorption performance of the absorbent body.

[0051] Multiple fiber filaments are intertwined to form multiple pores that provide a penetration path for moisture. There are multiple gaps formed by the composite of fiber filaments between adjacent fiber bundles 21. The porosity of the bundled fiber aggregate 2 is between 30% and 80%. The intertwined fiber filaments can increase the porosity of the bundled fiber aggregate 2, thereby improving the water permeability and breathability of the bundled fiber aggregate 2, and the longitudinal arrangement and aggregation of the fiber bundles 21 can ensure the structural strength of the bundled fiber aggregate 2.

[0052] It should be noted that the bundled fiber aggregate 2 is longitudinally assembled by a single layer of fiber bundles 21. The bottoms of multiple strands of the fiber bundles 21 are compounded with the bottom layer 4 through glue to form a compound area 23. More specifically, during the process of applying glue, the gaps between the single fibers may be blocked, reducing the water permeability of the compound area 23; in the non-compound area, due to the absence of interference from these materials, the water permeability is relatively good.

[0053] In this embodiment, the bundled fiber aggregate 2 is longitudinally assembled by a single layer of fiber bundles 21. This bundling method makes the structure of the bundled fiber aggregate 2 relatively uniform, and there is no arc conforming to the inner thigh at both ends, which is suitable for absorbent products such as sanitary napkins and pantiliners.

[0054] Embodiment Two

[0055] The difference between this embodiment and Embodiment One is as follows:

[0056] A bundled absorbent body, as Figure 6 shown, includes a surface layer 1 in direct contact with the human body, at least two layers of bundled fiber aggregates 2 provided below the surface layer 1, and a superabsorbent polymer layer 3 sandwiched between the bundled fiber aggregates 2. The superabsorbent polymer layer 3 includes superabsorbent polymer particles for absorbing and locking liquids. A liquid-impermeable bottom layer 4 is provided below the bundled fiber aggregate 2, and the bottom layer 4 is provided on the side of the bundled fiber aggregate 2 away from the superabsorbent polymer layer 3.

[0057] The overall absorption process of this embodiment: The liquid first contacts the surface layer 1, then the liquid penetrates downward through the surface layer 1, and then the bundled fiber aggregate 2 longitudinally diffuses the liquid and quickly transfers it from the surface layer 1 to the deeper superabsorbent polymer layer 3. The superabsorbent polymer particles in the superabsorbent polymer layer 3 quickly absorb and store a large amount of liquid. At the same time, the liquid-impermeable bottom layer 4 prevents liquid leakage and keeps the outside of the absorbent body dry.

[0058] Compared with Embodiment One, this embodiment adds a layer of bundled fiber aggregate 2 between the superabsorbent polymer layer 3 and the surface layer 2, further increasing the liquid storage capacity of the absorbent body. At the same time, this embodiment adopts the fiber coating method, using two layers of bundled fiber aggregates 2 to coat the SAP particles, significantly improving the liquid storage capacity and distribution uniformity of the absorbent body, thereby improving the performance and comfort of the product.

[0059] Embodiment Three

[0060] The difference between this embodiment and Embodiment One is as follows:

[0061] As Figure 4 And Figure 5As shown in the figure, arc-shaped structures 22 stacked inward from fiber bundles 21 are respectively provided at the middle positions of both ends of the bunch fiber aggregate 2 along its own transverse direction. The two arc-shaped structures 22 are mirror-symmetrically distributed, and the arc-shaped structure 22 is stacked into a double-layer or multi-layer structure by the fiber bundles 21.

[0062] This embodiment is different from the single-layer fiber bundle 21 of Embodiment 1, and the arc-shaped structure 22 is stacked on the basis of Embodiment 1. The arc-shaped structure 22 fits the radian of the inner thigh. The stacked arc-shaped structure 22 is thicker than the fiber bundles 21 in other places and has better absorption performance, playing an effect of preventing side leakage.

[0063] When the arc-shaped structure 22 is stacked into a double-layer structure, the ratio of the fiber bundles 21 stacked into a double-layer structure and arranged in the two arc-shaped structures 22 to the bunch fiber aggregate 2 is 1 / 10 to 1 / 2. Because the arc-shaped structure 22 is double-layer stacked, as Figure 5 shown, the width of the arc-shaped structure 22 is half of the width of the stacked fiber bundle 21.

[0064] When the ratio is less than 1 / 10, the width of the arc-shaped structure 22 is relatively narrow, the arc radian at both ends of the bunch fiber aggregate 2 is relatively small, and it cannot fit well with the inner thigh of the user. At the same time, the narrow width of the arc-shaped structure 22 results in insufficient effect of preventing side leakage. When the ratio is more than 1 / 2, the proportion of the middle position of the bunch fiber aggregate 2 will be too small, so that the two ends of the superabsorbent resin wrapped by it are also stacked, and it is easy to occur the phenomenon that the superabsorbent resin hinders secondary absorption, thus affecting the absorption performance of the absorbent body.

[0065] When the arc-shaped structure 22 is stacked into a multi-layer structure, the ratio of the fiber bundles 21 stacked into a multi-layer structure and arranged in the two arc-shaped structures 22 to the bunch fiber aggregate 2 is 1 / 15 to 1 / 4. Compared with the double-layer stacking, the width of the arc-shaped structure 22 of the multi-layer stacking is a fraction of the width of the stacked fiber bundle 21. Under the same width of the stacked fiber bundle 21, the more layers there are, the narrower the width of the arc-shaped structure 22. Therefore, the ratio interval of the multi-layer structure is narrower than that of the double-layer structure.

[0066] In this embodiment, arc-shaped structures 22 stacked inward from fiber bundles 21 are respectively provided at the middle positions of both ends of the bunch fiber aggregate 2 along its own transverse direction. The arc-shaped structure 22 fits the radian of the inner thigh, and the stacked arc-shaped structure 22 is thicker than the fiber bundles 21 in other places and has better absorption performance, playing an effect of preventing side leakage, and is applicable to absorbent products such as diapers.

[0067] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
