Description

Technical Field

[0001] This utility model relates to the field of absorbent underwear, specifically, to a polymer absorbent, deodorizing, and antibacterial underwear. Background Technology

[0002] During menstruation, women produce a large amount of discharge. Current underwear has limited absorbency, usually requiring the wearing of sanitary napkins to ensure good absorbency and moisture retention. However, wearing underwear while using sanitary napkins is not only cumbersome but also inconvenient. To reduce this hassle, there is an urgent need for underwear that incorporates materials similar to those used in sanitary napkins. Utility Model Content

[0003] The purpose of this invention is to provide a polymer absorbent, deodorizing, and antibacterial underwear, which solves the problem that existing underwear and sanitary napkins need to be worn separately, which is cumbersome and inconvenient in daily life.

[0004] The embodiments of this utility model are achieved through the following technical solutions:

[0005] A type of super absorbent, deodorizing, and antibacterial underwear comprises: a skin-friendly layer, a functional layer, and a distal layer stacked sequentially; the functional layer comprises: a super absorbent polymer layer and an activated carbon layer.

[0006] Preferably, the functional layer further includes a dustproof layer, wherein the activated carbon layer has the dustproof layer on at least one side.

[0007] Preferably, the activated carbon layer is provided on both sides of the polymer absorbent layer.

[0008] Preferably, the superabsorbent polymer layer is disposed near the skin layer, and the activated carbon layer is located on the side of the superabsorbent polymer layer away from the skin layer.

[0009] Preferably, the superabsorbent polymer layer comprises a nonwoven fabric layer and a superabsorbent polymer layer, wherein the superabsorbent polymer layer is located between the two nonwoven fabric layers.

[0010] Preferably, a waterproof layer is provided on the side of the polymer absorbent layer away from the skin layer, and the waterproof layer is disposed between the activated carbon layer and the skin layer.

[0011] Preferably, the orthographic projection of the polymer absorbent layer toward the waterproof layer falls entirely within the coverage area of ​​the waterproof layer, and the waterproof layer further includes a margin area surrounding the coverage area.

[0012] Preferably, the waterproof layer is connected to the distal skin layer, and the activated carbon layer is connected to the proximal skin layer via a first sewing thread, with an expansion gap between the first sewing thread and the polymer absorbent layer.

[0013] Preferably, the proximal skin layer and the distal skin layer are connected by a second sewing thread, which is further away from the superabsorbent polymer layer than the first sewing thread.

[0014] Preferably, a gap is left between the side of the allowance area away from the covered area and the second sewing line.

[0015] This utility model has at least the following beneficial effects:

[0016] This invention uses the quick-absorbing and water-locking material used in sanitary napkins in underwear, and combines it with an activated carbon layer to achieve the functions of water absorption, deodorization, and antibacterial properties. The waterproof layer is located between the activated carbon layer and the skin layer to avoid the waterproof layer from isolating the activated carbon layer and the super absorbent polymer layer, thus preventing the activated carbon layer from being unable to perform its function. The waterproof layer is also positioned away from the super absorbent polymer layer to accommodate changes in the thickness of the super absorbent polymer layer after it absorbs water, thus preventing the super absorbent polymer layer from being unable to effectively absorb water due to the obstruction of the waterproof layer.

Detailed Implementation

[0023] To make the objectives, methods, and advantages of the embodiments of this utility model clearer, the methods in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0024] Example 1: As Figure 1 As shown, a polymer absorbent, deodorizing, and antibacterial underwear includes: a skin-friendly layer 1, a functional layer 2, and a distal layer 3 stacked sequentially; the functional layer 2 includes: a polymer absorbent layer 4 and an activated carbon layer 5.

[0025] In specific implementation, the water-absorbing and water-locking material in the polymer absorbent layer 4 can be FlexFoam liquid material, a novel material composed of polymers with unique elasticity and water absorption. This material is liquefied through emulsification technology, similar to the porous structure of memory foam, which can quickly absorb and lock in liquids to prevent backflow. The activated carbon layer 5 can adopt a structure of two layers of non-woven fabric wrapping activated carbon fibers. In this embodiment, the functional layer 2 can be located close to the crotch area of ​​the underwear, and the structure or material of other parts can refer to existing technologies. Since this embodiment does not improve the shape of the underwear, the basic shape structure is not shown. The attached drawings mainly show the fabric structure of the functional area that achieves the water absorption and deodorization effect.

[0026] Existing underwear often has weak absorbency, requiring the wearing of sanitary napkins when the body secretes large amounts of fluid. Wearing underwear while using sanitary napkins is cumbersome and inconvenient, especially during toileting. Therefore, the applicant considered how to apply sanitary napkin materials to disposable underwear. This embodiment uses a fast-absorbing and moisture-locking material from sanitary napkins in the underwear, combined with an activated carbon layer 5 to achieve dual functions of absorbency and deodorization. The skin-friendly layer 1 and the distal layer 3 can be made of cotton.

[0027] Example 2: To avoid the problem caused by the shedding of activated carbon layer 5, improvements were made based on Example 1, such as... Figure 2 As shown, in this embodiment, the functional layer 2 further includes a dustproof layer 6, and the activated carbon layer 5 has the dustproof layer 6 on at least one side.

[0028] In practice, the dustproof layer 6 can be made of PE mesh film, which prevents activated carbon fibers from passing through while maintaining good breathability. Since the activated carbon layer 5 is made of activated carbon fibers, it will inevitably be disturbed by external forces during wear, resulting in friction and other phenomena. This may cause fibers and powder on the fibers to fall off, potentially causing stains if they come into direct contact with the wearer's body or outer trousers. The dustproof layer 6 can be placed on both sides of the activated carbon layer 5, while preventing it from affecting the body and outer trousers located on either side of the activated carbon layer 5.

[0029] Example 3: To enhance the deodorizing and sterilizing effect, improvements were made based on Example 1, such as... Figure 3 As shown, in this embodiment, the activated carbon layer 5 is provided on both sides of the polymer absorbent layer 4.

[0030] In the specific implementation process, a dustproof layer 6 can be set on the side of the two activated carbon layers 5 away from the polymer water-absorbing layer 4.

[0031] Example 4: In order to effectively utilize the function of activated carbon layer 5, improvements were made based on Example 1, such as... Figure 1 As shown, in this embodiment, the polymer absorbent layer 4 is disposed near the skin-like layer 1, and the activated carbon layer 5 is located on the side of the polymer absorbent layer 4 away from the skin-like layer 1.

[0032] In practice, the polymer absorbent layer 4 is closer to the human body than the activated carbon layer 5, allowing the liquids secreted by the body to be directly absorbed by the polymer absorbent layer 4. If the activated carbon layer 5 were placed closer to the body, the liquids secreted by the body would pass through the activated carbon layer 5 first before entering the polymer absorbent layer 4, reducing the deodorizing effect of the activated carbon layer 5. In addition, odor gases migrating from the polymer absorbent layer 4 towards the skin layer 3 would not be adsorbed by the activated carbon layer 5, also resulting in a poorer deodorizing effect of the product.

[0033] Example 5: Figure 1 As shown, this embodiment provides a structure of a polymer absorbent layer 4, which includes a non-woven fabric layer 41 and a polymer layer 42, with the polymer layer 42 located between the two non-woven fabric layers 41.

[0034] In practice, the polymer layer 42 can be connected to the nonwoven fabric layer 41 by sewing, heat sealing, or adhesive. Applying adhesive to fully bond the polymer layer 42 and the nonwoven fabric layer 41 can improve the stability of the connection between them.

[0035] Example 6: To avoid leakage of secretions, improvements were made based on Examples 1-5, such as... Figure 4 As shown, in this embodiment, the polymer absorbent layer 4 is provided with a waterproof layer 7 on the side away from the skin layer 1, and the waterproof layer 7 is disposed between the activated carbon layer 5 and the skin layer 3.

[0036] In specific implementation, the waterproof layer 7 can be made of materials such as TPU and GORE-TEX. Since the superabsorbent, deodorizing, and antibacterial underwear provided in this embodiment is mainly used in scenarios with large liquid outflow, such as for disabled elderly people, the waterproof layer 7 prevents liquid in the superabsorbent polymer layer 4 from seeping out. The waterproof layer 7 is not located between the activated carbon layer 5 and the superabsorbent polymer layer 4 because the waterproof layer 7 generally has low breathability. Isolating the activated carbon layer 5 and the superabsorbent polymer layer 4 with the waterproof layer 7 might hinder the effective functioning of the activated carbon layer 5. The function of the activated carbon layer 5 mainly relies on its extremely strong adsorption capacity, which can effectively adsorb odors. Its antibacterial effect is also achieved by adsorbing organic substances and other microbial metabolites that cause odors, indirectly reducing the opportunity for bacterial growth.

[0037] Example 7: To reduce the waterproofing effect of waterproof layer 7, improvements were made based on Example 6, such as... Figure 4 As shown, in this embodiment, the orthographic projection of the polymer absorbent layer 4 toward the waterproof layer 7 falls entirely on the covering area 71 of the waterproof layer 7. The waterproof layer 7 also has a margin area 72, which surrounds the covering area 71.

[0038] In practical implementation, this embodiment completely covers the superabsorbent polymer layer 4 with the waterproof layer 7, providing better protection. Furthermore, the waterproof layer 7 has a margin area 72, ensuring that even if the waterproof layer 7 is connected to other layers by sewing, resulting in seam holes, these holes will be far from the superabsorbent polymer layer 4, thus preventing them from affecting the overall waterproof performance of the waterproof layer 7. The waterproof layer 7 is not directly connected to the superabsorbent polymer layer 4, also avoiding any impact of sewing on the performance of either layer.

[0039] Example 8: To further improve the waterproof effect, improvements were made based on Example 7, such as... Figure 4 As shown, in this embodiment, the waterproof layer 7 is connected to the distal skin layer 3, the activated carbon layer 5 is connected to the proximal skin layer 1 through the first sewing line 8, and an expansion gap is left between the first sewing line 8 and the polymer absorbent layer 4.

[0040] In the specific implementation process, the waterproof layer 7 can be connected to the distal skin layer 3 by bonding. Since both the activated carbon layer 5 and the waterproof layer 7 have poor elasticity, when they are simultaneously connected to the proximal skin layer 1, the wrinkling problem caused by the difference in elasticity between them during sewing is quite severe. Therefore, in this embodiment, the waterproof layer 7 is connected to the distal skin layer 3. The connection between the activated carbon layer 5 and the proximal skin layer 1 also allows the activated carbon layer 5 to wrap around the superabsorbent polymer layer 4, preventing or reducing liquid seepage from the sides of the superabsorbent polymer layer 4. Since the thickness of the superabsorbent polymer layer 4 changes to a certain extent after absorbing water, in this embodiment, there is a certain expansion gap between the first sewing line 8 and the superabsorbent polymer layer 4. This gap allows the space between the activated carbon layer 5 and the proximal skin layer 1 to adapt to the volume change of the superabsorbent polymer layer 4. If the first sewing line 8 is placed close to the edge of the superabsorbent polymer layer 4, the space between the activated carbon layer 5 and the proximal skin layer 1 cannot be increased adaptively when the superabsorbent polymer layer 4 absorbs water. Therefore, under the limitation of space size, the water absorption effect of the superabsorbent polymer layer 4 cannot be fully and effectively utilized.

[0041] It should be noted that, theoretically, there is always a certain gap between the first sewing thread 8 and the polymer absorbent layer 4 during sewing. The expansion gap mentioned in this embodiment refers to the gap width being sufficient to satisfy the spatial changes when the polymer absorbent layer 4 reaches its maximum water absorption. The expansion gap can be 1cm.

[0042] Example 9: As Figure 4 As shown, in this embodiment, the proximal skin layer 1 and the distal skin layer 3 are connected by a second sewing thread 9, which is further away from the polymer absorbent layer 4 than the first sewing thread 8.

[0043] In the specific implementation process, the near-skin layer 1, the far-skin layer 3 and the functional layer 2 in this embodiment are not directly sewn together in one go, but are sewn in multiple sections, which can reduce the discomfort caused by the sewn area formed during the sewing process, especially the discomfort caused by the sewn area formed under the elasticity difference of the multi-layer structure.

[0044] Example 10: A gap is left between the side of the allowance area (72) away from the covering area (71) and the second sewing line (9).

[0045] In practice, the excess area does not directly participate in the sewing of the second sewing line 9, which can reduce the impact of the sewing holes on the waterproofing of the waterproof layer 7.

[0046] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
