DETAILED DESCRIPTION
[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0026] In order to solve the problems of poor liquid absorption, poor dryness and poor comfort of sanitary absorbent products in the related art, such as Figure 1 As shown, the utility model provides a novel sanitary absorbent product, comprising a liquid-permeable surface layer 100, a softening layer 200, an absorbent core 300 or a breathable bottom layer 400 arranged in sequence from top to bottom; wherein the softening layer 200 is composed of two mutually parallel first soft silicone strips 201 and a second soft silicone strip 202, the second soft silicone strip 202 is located between the two first soft silicone strips 201 and is perpendicular to the two first soft silicone strips 201, so that the softening layer 200 is H-shaped; a plurality of guide holes are evenly distributed on the softening layer.
[0027] In the embodiment of the utility model, a softening layer 200 is arranged below the liquid-permeable surface layer 100. The softening layer 200 is composed of a plurality of soft silicone strips arranged mutually so that the softening layer 200 is H-shaped, so that it can not only play a role in supporting the liquid-permeable surface layer 100 and the absorbent core 300, but also increase the softness and air permeability of the sanitary product; further, a plurality of guide holes 203 are evenly arranged on the softening layer 200. When the liquid infiltrates from the liquid-permeable surface layer 100 to the softening layer 200, not only the infiltration speed of the liquid can be accelerated, but also the liquid can be effectively prevented from back-infiltrating through the softening layer 200 to the liquid-permeable surface layer 100, thereby ensuring that the sanitary absorbent product has excellent dryness.
[0028] According to some preferred embodiments, the two first soft silicone strips 201 are arranged along the length direction, the second soft silicone strip 202 is arranged along the width direction, and the second soft silicone strip 202 is located in the middle area of the first soft silicone strip 201 .
[0029] Considering that liquids are generally concentrated in the central area of hygienic absorbent articles, e.g. Figure 2 As shown, in this embodiment, two first soft silicone strips 201 are arranged along the length direction, and the second soft silicone strip 202 is arranged along the width direction, that is, the softening layer 200 is H-shaped along the length direction of the sanitary absorbent product, the length of the first soft silicone strip 201 is the same as the length of the liquid-permeable surface layer 100, and the width of the second soft silicone strip 202 is the same as the liquid-permeable surface layer 100. At this time, the second soft silicone strip 202 is located in the central area of the sanitary absorbent product, which not only increases the softness and air permeability of the sanitary absorbent product, but also better supports the liquid-permeable surface layer 100, so that the sanitary absorbent product has better dryness and comfort.
[0030] According to some preferred embodiments, in the second soft silicone strip 202 , the pore size and density of the guide holes 203 decrease outward from the central area, and in the first soft silicone strip 201 , the pore size of the guide holes 203 is the same.
[0031] According to some preferred embodiments, in the second soft silicone strip 202, the diameter of the guide hole 203 is 2-6 mm (for example, it can be 2 mm, 3 mm, 4 mm, 5 mm or 6 mm); in the first soft silicone strip 201, the diameter of the guide hole 203 is 1-2 mm (for example, it can be 1 mm, 1.5 mm or 2 mm).
[0032] like Figure 3As shown, considering that the soft silicone has a poor liquid absorption capacity, in this embodiment, the liquid absorption speed of the soft layer 200 can be reduced by setting the guide holes 203 on the soft layer 200, and the aperture of the guide holes 203 located in the central area of the soft layer 200 is set to decrease from the central area to the outside, that is, the aperture of the guide holes 203 in the central area is the largest, and a plurality of circles of guide holes 203 are distributed around the guide holes 203 in the central area, and the aperture of each circle of guide holes 203 gradually decreases from the central area to the outside, and the setting density of each circle of guide holes 203 gradually increases, and the aperture of the guide holes 203 is further controlled, which is not only conducive to enhancing the liquid absorption speed of the central area of the soft layer 200, but also can effectively prevent the liquid from osmosis through the soft layer 200 to the liquid permeable surface layer 100, and can also prevent the liquid from leaking sideways. At the same time, considering that the amount of liquid on both sides of the sanitary absorbent product is small, the guide holes 203 in the first silicone strip on both sides of the length direction of the sanitary absorbent product are set to the above-mentioned size, which is beneficial to further improve the liquid absorption performance of the softening layer 200 and increase the air permeability and comfort of the sanitary absorbent product.
[0033] According to some preferred embodiments, the liquid-permeable surface layer 100 is a hot air nonwoven fabric or a spunbond nonwoven fabric; wherein the liquid-permeable surface layer 100 contains coconut oil fibers with a mass fraction of 5-20% (for example, 5%, 10%, 15% or 20%).
[0034] In this embodiment, the liquid-permeable surface layer 100 is preferably a fine-denier hot-air non-woven fabric with a fiber denier of 1-2 denier. The non-woven fabric is delicate and soft. Directly contacting it with the user can ensure good comfort for the user. The liquid-permeable surface layer 100 contains 5-20% by mass of coconut oil fiber. The coconut oil fiber not only has a moisturizing effect, but also has good antibacterial and deodorizing effects. Mixing it with other fibers to make a fine-denier hot-air non-woven fabric can not only further enhance the softness of the liquid-permeable surface layer 100, but also enable the liquid-permeable surface layer 100 to have an antibacterial and deodorizing effect. It should be noted that the liquid-permeable surface layer containing coconut oil fiber was purchased from Shanghai Fengge Nonwoven Fabric Co., Ltd.
[0035] According to some preferred embodiments, the absorption core 300 includes a first absorption layer 301 and a second absorption layer 302 arranged in sequence from top to bottom; wherein the area of the second absorption layer 302 is larger than that of the first absorption layer 301, and the second absorption layer 302 is located in the central area of the first absorption layer 301.
[0036] According to some preferred embodiments, the first absorption layer 301 is polyurethane foam, and the second absorption layer 302 is composed of at least one layer of super absorbent resin absorbent paper.
[0037] like Figure 4 As shown, in this embodiment, by setting the absorption core 300 to a first absorption layer 301 and a second absorption layer 302 of different materials, the first absorption layer 301 adopts polyurethane foam with good softness and good liquid absorption performance, and the second absorption layer 302 adopts highly absorbent resin absorbent paper with excellent liquid absorption and liquid retention performance, and the area of the first absorption layer 301 is smaller than the area of the second absorption layer, and the length of the first absorption layer 301 is slightly larger than the length of the second soft silicone strip 202 in the softening layer 200. By setting the first absorption layer 301 in the central area of the second absorption layer 302 and the second soft silicone strip 202, the absorption core 300 can present a structure with a high middle and low surroundings, which can make the sanitary absorbent product fit the user better. In this way, when the liquid is guided to the absorption core 300 through the softening layer 200, a large amount of liquid is quickly absorbed by the first absorption layer 301, and then diffused through the first absorption layer 301 to the second absorption layer 302 and stored, so that the sanitary absorbent product has excellent liquid absorption and liquid retention performance.
[0038] According to some preferred embodiments, the first absorption layer 301 is provided with a plurality of through holes 304, the aperture of the through holes 304 is 3-10 mm (for example, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm), and the interval between adjacent through holes 304 is 5-10 mm (for example, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm). The second absorption layer 302 is provided with a plurality of slits 303, the length of the slits 303 is 1-5 cm (for example, 1 cm, 2 cm, 3 cm, 4 cm or 5 cm), and the interval between adjacent slits 303 is 5-20 mm (for example, 5 mm, 10 mm, 15 mm, 20 mm).
[0039] Continue to refer Figure 4 In this embodiment, by further providing a plurality of through holes 304 on the first absorbent layer 301 and a plurality of slits 303 on the second absorbent layer 302, and by reasonably controlling the space of the through holes 304 and the length of the slits 303, it is possible to ensure good air permeability of the sanitary absorbent product while further enhancing the liquid absorption speed of the absorbent core 300 and preventing liquid leakage, thereby avoiding the discomfort caused by poor air permeability.
[0040] It should be noted that the utility model does not specifically limit the hole shape of the guide hole 203 and the through hole 304. Those skilled in the art can make adaptive adjustments according to needs. For example, it can be circular, elliptical, rectangular, square or diamond-shaped. At the same time, when the guide hole 203 and the through hole 304 are non-circular, the aperture is expressed by the circumscribed circular aperture of the corresponding shape.
[0041] According to some preferred embodiments, the thickness of the softening layer 200 is 0.5-4 mm (for example, 0.5 mm, 1 mm, 2 mm, 3 mm or 4 mm), and the thickness of the polyurethane foam is 0.5-4 mm (for example, 0.5 mm, 1 mm, 2 mm, 3 mm or 4 mm).
[0042] In this embodiment, by setting the thickness of the polyurethane foam of the softening layer 200 and the first absorption layer 301 to the above range, the sanitary absorbent product can be made softer and more comfortable on the basis of having better liquid absorption performance.
[0043] According to some preferred embodiments, the breathable bottom layer 400 is a PE breathable film.
