[0001] This utility model relates to the field of adult diaper technology, specifically to a multi-layer absorbent adult diaper. Background Technology

[0002] Adult diapers are disposable paper-based incontinence products, a type of adult care product primarily designed for incontinent adults. They typically consist of a top layer, an absorbent layer, and a bottom layer, designed to absorb the user's secretions, thus preventing staining clothing and keeping it clean. However, existing adult diapers, due to the large volume of excretions in adults, suffer from slow absorption, poor flow control, and low absorbency, leading to decreased user comfort and increased susceptibility to bacterial growth, resulting in odors or even physiological illnesses. Therefore, to overcome these shortcomings, improvements to the existing technology are necessary. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and provide a multi-layer absorbent adult diaper with fast absorption speed and large absorption capacity.

[0004] This utility model is achieved through the following technical solution:

[0005] A multi-layer absorbent adult diaper includes a diaper body with a cotton core wrapped inside. The diaper body is provided with a liquid-permeable layer, an antibacterial layer, a diversion layer, a liquid-impermeable layer, and a breathable bottom film layer from top to bottom. The cotton core is provided with a first wood pulp mixed superabsorbent polymer layer, a superabsorbent polymer layer, and a second wood pulp mixed superabsorbent polymer layer from top to bottom. The upper surface of the cotton core is provided with a plurality of protrusions, and the protrusions form interconnected diversion channels.

[0006] Furthermore, the antibacterial layer is a bamboo charcoal fiber antibacterial layer.

[0007] Furthermore, the liquid-permeable layer is a non-woven fabric liquid-permeable layer with an adhesive-like finish, and the flow-guiding layer is a non-woven fabric flow-guiding layer with an adhesive-like finish.

[0008] Furthermore, the impermeable layer is a cast film impermeable layer.

[0009] Furthermore, the breathable bottom membrane layer is a PE breathable bottom membrane layer.

[0010] Furthermore, the upper part of the cotton core has upper protrusions on both the left and right sides, and the lower part of the cotton core has lower protrusions on both the left and right sides.

[0011] Furthermore, the diaper body has a front waistband and a back waistband on its upper and lower sides, respectively. The bottom surface of the front waistband is provided with a front waistband sticker, and the left and right sides of the back waistband are provided with adhesive strips corresponding to the front waistband sticker.

[0013] Furthermore, the protrusion is a circular protrusion.

[0014] Furthermore, the protrusions that are adjacent to each other on the left and right are staggered.

[0015] Compared to existing technologies, this invention features a diaper body comprising, from top to bottom, a liquid-permeable layer, an antibacterial layer, a diversion layer, a liquid-impermeable layer, and a breathable bottom film layer. The cotton core, from top to bottom, comprises a first wood pulp mixed superabsorbent polymer (SAP) layer, a SAP layer, and a second wood pulp mixed SAP layer. The upper surface of the cotton core has several protrusions forming interconnected diversion channels. The combination of the first, second, and third SAP layers results in high absorbency and better breathability, while also reducing manufacturing costs. The diversion channels quickly and evenly guide excrement, ensuring thorough absorption by the cotton core, thus solving problems of slow absorption, poor diversion effect, and low absorbency. The antibacterial layer provides antibacterial protection, effectively preventing rashes, itching, odor, and other discomfort, improving user comfort and providing peace of mind.
