Description

Technical Field

[0001] This utility model relates to the field of disposable hygiene products technology, and more specifically, it relates to a dry surface layer for disposable hygiene products. Background Technology

[0002] Disposable hygiene products are a widely used category of personal care products, primarily used to absorb liquids, keep skin dry, and provide hygienic protection. They are commonly used in personal care, medical care, and daily life, and are characterized by their convenience, hygiene, and ease of use.

[0003] Disposable hygiene products play an indispensable role in modern life, greatly improving convenience and hygiene. Among these many key factors, the dry-off layer, as the first material in direct contact with the skin, is of paramount importance.

[0004] As a key component of disposable hygiene products, the dry-surface layer plays an important role in improving the user experience and product performance. However, current single-surface layer technology still has some drawbacks. For example, traditional single-surface layer materials may experience backflow after absorbing liquid, causing users' skin to be in contact with a humid environment for a long time, which may lead to skin problems. At the same time, some single-surface layers have insufficient breathability, which can easily cause the skin to feel stuffy and affect the comfort of use. Therefore, a dry-surface layer for disposable hygiene products is proposed to improve the existing problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dry surface layer for disposable hygiene products.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a dry surface layer for disposable hygiene products, comprising an upper surface layer and a lower surface layer disposed at the bottom of the upper surface layer; the upper surface layer includes a hydrophobic surface and a hydrophilic surface, which are alternately distributed; the lower surface layer is provided with a plurality of micropores.

[0007] The present invention is further configured such that the upper surface layer and the lower surface layer are superimposed to form a double-layer structure, and the hydrophobic surface and the hydrophilic surface are both located on the side of the upper surface layer away from the lower surface layer.

[0008] The present invention is further configured such that the upper and lower surface layers are both made of hydrophilic nonwoven fabric.

[0009] The present invention is further configured such that: protrusions are provided on the hydrophobic surface, the protrusions are evenly and equidistantly arranged, and the shape of the protrusions is irregular.

[0010] The present invention is further configured such that: a plurality of protrusions are spaced apart on the hydrophobic surface, and the protrusions are positioned higher than the hydrophilic surface.

[0011] The present invention is further configured such that the hydrophilic surface is disposed between the two protrusions.

[0012] The present invention is further configured such that the micropores are uniformly arranged below the hydrophilic surface, and the micropores are configured as inverted cones.

[0013] In summary, this application includes at least one of the following beneficial technical effects: By cleverly combining hydrophobic and hydrophilic surfaces, the liquid is rapidly and directionally drained, significantly improving the product's absorption performance. At the same time, since the part in contact with the skin is mainly composed of hydrophobic surfaces, this design not only ensures that the liquid can be absorbed quickly, but also keeps the skin contact area dry, thus providing users with a long-lasting dry experience and maintaining comfort and hygiene even during prolonged use.

[0015] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0017] Please see Figures 1-3 The present invention provides the following technical solution: Example 1, see Figures 1-3 A dry surface layer for disposable hygiene products includes an upper surface layer 1 and a lower surface layer 2 disposed at the bottom of the upper surface layer 1; the upper surface layer 1 includes a hydrophobic surface 3 and a hydrophilic surface 4, which are distributed alternately; the lower surface layer 2 is provided with a plurality of micropores 5.

[0018] When the liquid comes into contact with the upper surface 1, it will first meet the hydrophobic surface 3 and then be guided to the hydrophilic surface 4. This process ensures that the hydrophobic surface 3 is dry and provides a comfortable experience for the user.

[0019] After absorbing liquid, the hydrophilic surface 4 can quickly conduct the liquid to the lower surface layer 2. The lower surface layer 2, with its uniformly distributed micropores 5, can efficiently guide and diffuse the liquid to other areas, thereby significantly improving the absorption efficiency.

[0020] This ingenious combination of hydrophobic surface 3 and hydrophilic surface 4 enables rapid directional drainage of liquids, significantly improving the product's absorption performance. At the same time, since the part in contact with the skin is mainly composed of hydrophobic surface 3, this design not only ensures that the liquid can be absorbed quickly, but also keeps the skin contact area dry, thus providing users with a long-lasting dry experience and maintaining comfort and hygiene even during prolonged use.

[0021] See Figures 1-3 Furthermore, the upper surface layer 1 and the lower surface layer 2 are superimposed to form a double-layer structure, with the hydrophobic surface 3 and the hydrophilic surface 4 both located on the side of the upper surface layer 1 away from the lower surface layer 2.

[0022] See Figures 1-3 Furthermore, both the upper surface layer 1 and the lower surface layer 2 are made of hydrophilic non-woven fabric.

[0023] See Figures 1-3 Furthermore, the hydrophobic surface 3 is provided with protrusions, which are evenly and equidistantly arranged, and the protrusions are irregular in shape.

[0024] Among them, the protrusions on the hydrophobic surface 3 are embossed and can be presented in various shapes according to production needs. Taking the arc shape as an example, when the liquid flows to the top of the protrusion, due to the influence of gravity, the liquid will naturally flow down along the contour of the arc and will not stay on the hydrophobic surface 3 for a long time. By setting the protrusion structure, not only is the residence time of the liquid on the surface effectively shortened, but also a rapid and directional guiding function is achieved, so that the droplets can leave the surface quickly along the preset path, thereby significantly improving the absorption efficiency of the liquid.

[0025] See Figures 1-3 Furthermore, multiple protrusions are spaced apart on the hydrophobic surface 3, and the protrusions are higher than the hydrophilic surface 4.

[0026] In this design, the protrusion of the hydrophobic surface 3 is higher than that of the hydrophilic surface 4. This design allows liquid to be naturally guided to the hydrophilic surface 4 when it comes into contact with the hydrophobic surface 3. The hydrophilic surface 4 then conducts the liquid to the lower surface layer 2. This process not only ensures that the hydrophobic surface 3 always stays dry, avoiding the dampness and discomfort caused by liquid residue and backflow to the skin, but also improves the absorption efficiency and comfort of the entire dry surface layer by quickly absorbing and conducting liquid.

[0027] See Figures 1-3 Furthermore, the hydrophilic surface 4 is positioned between the two protrusions.

[0028] See Figures 1-3 Furthermore, micropores 5 are evenly distributed below the hydrophilic surface 4, and the micropores 5 are configured as inverted cones.

[0029] Among them, the inverted conical structure of the micropore 5 can effectively guide the liquid to flow downward quickly, reduce the residence time of the liquid on the lower surface layer 2, thereby accelerating the absorption speed and improving the overall liquid conduction efficiency. On the other hand, the inverted conical structure makes it difficult for the liquid to backflow after being absorbed, because its structure restricts the path of liquid return, thus better keeping the hydrophobic surface 3 dry.

[0030] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
