Description

Technical Field

[0001] The present invention relates to the technical field of urine pads, and particularly to a urine pad made of a waterproof and breathable membrane. Background Art

[0002] In family life, the comfort of children, the elderly, or patients at home has become the key to a family's happiness. Especially for infants and the elderly with limited mobility who are unable to take care of themselves, it has become a concern for many families. With the development of society, disposable diapers have been developed to solve these problems, but disposable diapers also have some problems, such as poor breathability, causing skin allergies, etc. For long-term bedridden patients, due to long-term local tissue compression of the body, blood circulation is blocked, resulting in necrosis or ulceration and forming bedsores, etc. None of these problems can be solved by a simple urine pad or protective pad.

[0003] Traditional urine pads usually adopt a multi-layer structure, including a skin-friendly layer, a water-absorbing layer, and a waterproof layer. However, most products still need to be improved in terms of waterproof and breathable performance, antibacterial performance, water absorption capacity, cleaning and maintenance convenience, and comfort.

[0004] There is a common urine pad. This urine pad adopts a multi-layer structure design, including a non-woven fabric surface layer, a wood pulp water-absorbing layer, and a PE waterproof layer. Although this design can provide basic waterproof and water absorption functions, the PE waterproof layer has poor breathability, which easily causes the skin to be wet and leads to problems such as red buttocks. In addition, the water absorption capacity of the wood pulp water-absorbing layer is limited, and it cannot quickly absorb a large amount of urine, easily resulting in back leakage.

[0005] There is also an improved urine pad. This urine pad adopts a design of a skin-friendly layer, a water-absorbing layer, and a waterproof and breathable layer. Although the breathability has been improved, the antibacterial performance and wear resistance of its waterproof and breathable layer are insufficient, which easily breeds bacteria and affects the health of infants. At the same time, the cleaning and maintenance of this product are still not convenient enough, and dirt and odor are easily left on the bottom layer material. Summary of the Invention

[0006] (I) Technical Problems to be Solved In view of the deficiencies of the prior art, the present invention provides a urine pad made of a waterproof and breathable membrane, which solves the problems raised in the above background art.

[0011] Preferably, the water-absorbing and liquid-storing layer is made of a mixture of wood pulp and SAP particles. The production process of the water-absorbing and liquid-storing layer is that after the wood pulp is dispersed, loosened and fluffed, SAP particles are added, and it is formed into a long strip-shaped intermediate water-absorbing layer through a carding machine. Then, SAP particles are sprayed on the surface of the intermediate water-absorbing layer to form a strong water-absorbing layer. A PU coating is fixedly connected to the bottom of the water-absorbing and liquid-storing layer, and carbon black is mixed inside the PU coating. The water-absorbing and liquid-storing layer and the skin-friendly layer are fixed by a cold pressing and laminating process.

[0012] Preferably, the waterproof and breathable film layer is based on polytetrafluoroethylene and combined with PE to form a composite film structure. The surface of the composite film structure is subjected to a surface treatment technology by plasma to coat a hydrophobic coating to ensure excellent waterproof and breathable performance.

[0013] Preferably, the supporting bottom layer is made of polyester double-sided cloth material, and a number of semi-circular protrusions are fixedly connected to the lower side wall of the supporting bottom layer to enhance the anti-slip performance.

[0014] Preferably, the supporting bottom layer and the waterproof and breathable film layer are bonded by hot melt adhesive dots.

[0015] (III) Beneficial Effects The present invention provides a waterproof and breathable film-made urine pad, which has the following beneficial effects: 1. This invention utilizes a polytetrafluoroethylene and PE composite membrane structure, plasma surface treatment, and hydrophobic coating to ensure excellent waterproof and breathable properties.

[0017] 3. The water-absorbing and liquid-storage layer uses a combination of wood pulp and SAP particles, which has a high water absorption rate and can quickly absorb and lock liquids to prevent reverse osmosis. The middle water-absorbing layer is formed into a long strip through a combing mechanism, and SAP particles are sprayed on the surface to form a strong water-absorbing layer, ensuring excellent water absorption performance.

[0018] 4. The support base is made of polyester double-sided fabric with a smooth surface, easy to clean, and chemical-resistant, and can be cleaned with detergent. The semi-circular raised design enhances the anti-slip performance and facilitates dirt removal.

[0019] 5. The skin-friendly layer is made of organic cotton and bamboo fiber and has been softened to make it soft to the touch and friendly to baby's skin. The softening treatment involves soaking in a softener solution at 30℃-40℃ for 10-20 minutes to ensure the skin-friendly layer is soft and comfortable. BRIEF DESCRIPTION OF THE DRAWINGS
