Description

Technical Field

[0001] This utility model relates to the field of diaper technology, specifically to an antibacterial and deodorizing adult diaper. Background Technology

[0002] Chinese Patent Publication No. CN214231735U discloses a zeolite diaper, which includes a diaper body. The crotch area in the middle of the diaper body has a concave space. The diaper body is provided with a leak-proof bottom layer, a water-locking layer, an absorbent layer, a permeable layer, an antibacterial layer and a contact layer from top to bottom. An absorbent core is provided in the interlayer of the absorbent layer and the absorbent core is filled with zeolite material.

[0003] This invention features an absorbent layer that provides good water absorption, odor removal, and antibacterial properties. Zeolite powder is filled into the absorbent core, utilizing the adsorption, ion exchange, and catalytic properties of zeolite to reduce dampness and stuffiness. However, the inclusion of an antibacterial layer results in an overly thick product. Furthermore, the antibacterial function of the layer is rapidly lost after the first contact with urine, making it difficult to maintain its effectiveness over the duration of wear. Utility Model Content

[0004] Therefore, in order to address the above problems, this utility model provides an antibacterial and deodorizing adult diaper, which solves the problems of existing diapers with added zeolite powder being thick and having a short duration of antibacterial effect.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] An antibacterial and deodorizing adult diaper includes, from top to bottom, a liquid-permeable top layer, a flow-guiding layer, an absorbent core, and a liquid-impermeable bottom layer, and further includes an antibacterial and deodorizing chip. The antibacterial and deodorizing chip is disposed between the flow-guiding layer and the covering layer that encapsulates the absorbent core. The antibacterial and deodorizing chip is composed of a surface-modified natural zeolite carrier, lactic acid loaded in the pores of the carrier, and fiber material through an airflow web forming process. The natural zeolite carrier is in powder form.

[0007] Furthermore, the particle size of the natural zeolite carrier is 50-200 μm.

[0008] Furthermore, the mass ratio of the natural zeolite carrier to the lactic acid it supports is 0.2-0.25.

[0009] Furthermore, the antibacterial and deodorizing chip is fixed to the flow guiding layer or the coating layer by hot pressing or adhesive bonding.

[0010] Furthermore, the antibacterial and deodorizing chips are arranged in the form of multiple parallel strips or a dot matrix.

[0011] Furthermore, the antibacterial and deodorizing chip is also mixed with superabsorbent polymer particles.

[0012] Furthermore, the fiber material is one or more of polyester fiber, polypropylene fiber, or ES fiber.

[0013] Furthermore, the mass ratio of the natural zeolite carrier to the fiber material is 3-5.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention uses high specific surface area natural zeolite, and controls the particle size through ultra-fine grinding and gradation technology to improve the carrier-lactic acid binding efficiency. Lactic acid solution is loaded through pore size control and surface modification technology, and food-grade lactic acid is embedded into the zeolite channels using vacuum impregnation method to form a stable slow-release system. The antibacterial and deodorizing chip is embedded between the diaper's distribution layer and wrapping layer and fixed by hot pressing to ensure that the function is activated immediately upon contact with urine. The strong adsorption of zeolite is used to actively capture odor molecules such as ammonia and sulfides in urine, while the slow-release lactic acid destroys bacterial biofilm, realizing a dual deodorization mechanism of "adsorption decomposition + active antibacterial".

[0020] 1. Liquid-permeable surface layer; 2. Flow guiding layer; 3. Antibacterial and deodorizing chip; 4. Coating layer; 5. Absorbent core; 6. Liquid-impermeable bottom layer. Detailed Implementation

[0021] The following will describe the implementation of this utility model in detail with reference to specific embodiments, so that the process of how this utility model uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] Example 1: As Figures 1 to 2 As shown, this embodiment provides an antibacterial and deodorizing adult diaper, which includes, from top to bottom, a liquid-permeable surface layer 1, a diversion layer 2, an antibacterial and deodorizing chip 3, a covering layer 4, an absorbent core 5, and a liquid-impermeable bottom layer 6.

[0023] The antibacterial and deodorizing chip 3 is disposed between the flow guiding layer 2 and the coating layer 4 that encapsulates the absorbent core 5. The chip is fixed to the coating layer 4 by an ultrasonic hot-pressing device, arranged in three parallel strips.

[0024] The antibacterial and deodorizing chip 3 is composed of the following components through an airflow web-forming process:

[0025] Surface-modified natural zeolite carrier: This carrier is in powder form with a particle size of approximately 70-80 μm. The zeolite carrier is surface-modified using a silane coupling agent ethanol solution.

[0026] Lactic acid: The lactic acid is loaded into the pores of the zeolite carrier. Testing showed that the mass ratio of the natural zeolite carrier to the loaded lactic acid was approximately 22%.

[0027] Fiber material: The fiber material used in this embodiment is ES fiber. The mass ratio of the natural zeolite carrier (containing loaded lactic acid) to the ES fiber is approximately 4:1.

[0028] Example 2: The difference between this example and Example 1 is that the antibacterial and deodorizing chip 3 is also uniformly mixed with superabsorbent polymer (SAP) particles. The mass ratio of SAP particles to zeolite particles is 0.2-1, preferably 0.4-0.7. In this example, a mass ratio of 0.5 is selected.

[0029] Compared with Embodiment 1, the advantage of this embodiment is that it can maintain the diaper's instant absorption capacity without affecting the antibacterial and deodorizing chip 3.

[0030] Example 3: Figure 3 As shown, the difference between this embodiment and Embodiment 1 is that the antibacterial and deodorizing chip 3 is laid in a dot matrix pattern between the flow guiding layer and the coating layer.

[0031] Example 4: The difference between this example and Example 1 is that the fiber material is a mixture of polyester fiber and polypropylene fiber.

[0032] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
